WEBVTT

00:00:00.560 --> 00:00:07.279
what the heck look at this thing

00:00:05.440 --> 00:00:12.960
i have never in all my years seen a CPU that looks

00:00:10.880 --> 00:00:17.359
anything like that that's it

00:00:14.160 --> 00:00:20.640
that's the CPU so the bare dye is

00:00:17.359 --> 00:00:22.320
exposed it's got like this looks like

00:00:20.640 --> 00:00:28.320
it's an aluminum like mounting plate thing that is then

00:00:25.279 --> 00:00:29.199
screwed into what would normally be the

00:00:28.320 --> 00:00:33.520
the mounting plate for the socket where the

00:00:31.760 --> 00:00:37.120
CPU would fit the back plate's normal but hold on here

00:00:35.520 --> 00:00:42.960
we go this is it what even are these things

00:00:41.200 --> 00:00:48.399
how would you be expected to install them so our story begins

00:00:46.079 --> 00:00:52.160
with the word from our sponsor Corsair Corsair's hydrox series of custom water

00:00:50.399 --> 00:00:56.000
cooling components has great performance RGB etc etc you're going to find out a

00:00:54.800 --> 00:01:02.000
lot more about it as the video progresses because we're going to be using a hydrox setup to cool

00:01:00.000 --> 00:01:06.400
this okay not this this is a motherboard but

00:01:04.400 --> 00:01:13.439
inside this box is something the likes of which i have

00:01:09.920 --> 00:01:16.880
never seen anything quite like so this

00:01:13.439 --> 00:01:18.880
is actually a big long note from tim

00:01:16.880 --> 00:01:27.040
a big fan of the channel and the new local supplier of bga to lga 1151

00:01:23.040 --> 00:01:29.439
cpus and tim has actually sent us over a

00:01:27.040 --> 00:01:32.720
whack of these cpus to check out and what's interesting about them

00:01:31.439 --> 00:01:39.680
is that these are laptop processors so bga or ball

00:01:37.280 --> 00:01:44.400
grid array chips that are designed to be soldered directly onto a motherboard and

00:01:42.240 --> 00:01:47.600
then with you know some kind of custom cooling solution applied over top of

00:01:46.240 --> 00:01:53.759
them like heat pipes or whatever the case may be so these are these laptop

00:01:50.159 --> 00:01:56.399
cpus these bga cpus that are soldered

00:01:53.759 --> 00:01:59.920
instead of to a laptop motherboard to this

00:01:57.200 --> 00:02:05.680
carrier adapter pcb and then in turn no wait okay so no this

00:02:02.880 --> 00:02:10.239
is actually a super thick pcb that the ball grid array CPU is soldered

00:02:07.920 --> 00:02:15.440
onto and then there's going to have to be pass-through traces inside it which

00:02:12.959 --> 00:02:21.520
we can't see and then it's actually just machined out on either side so that this

00:02:18.319 --> 00:02:23.760
bottom lga 1151 compatible

00:02:21.520 --> 00:02:28.000
surface here full of contact pads can fit properly in the socket wow

00:02:26.400 --> 00:02:32.800
there's a couple things that are unique about this solution one of them is of

00:02:30.319 --> 00:02:40.239
course the adapter and the second is this piece right here so this is the

00:02:36.519 --> 00:02:42.239
su-pch named presumably for mr sue who

00:02:40.239 --> 00:02:46.720
is running this operation now this does a couple of things number one is it

00:02:44.400 --> 00:02:51.200
takes our custom pcb here and allows us to

00:02:49.120 --> 00:02:56.160
have it held in place so there's actually four little mounting holes on

00:02:53.760 --> 00:03:01.360
the corners and those correspond to four little pegs on the inside of this uh

00:02:58.959 --> 00:03:06.560
this adapter plate here the second thing that it does is it acts as a shim which

00:03:04.239 --> 00:03:11.200
is a way of keeping the CPU safe when you're mounting a cooler to it now in

00:03:08.400 --> 00:03:16.720
the old days desktop processors just like their mobile counterparts had

00:03:13.360 --> 00:03:18.400
exposed dies like this but nowadays in

00:03:16.720 --> 00:03:22.319
order to keep them from getting cracked while people are you know applying heat

00:03:20.239 --> 00:03:26.400
things to them and stuff like that most manufacturers cover their chips with an

00:03:24.319 --> 00:03:31.360
ihs or an integrated heat spreader now that comes with actually a heat transfer

00:03:28.560 --> 00:03:35.840
penalty but it was seen as not being as important as keeping the things from

00:03:33.040 --> 00:03:40.239
getting cracked and chipped and broken so this shin that goes around it

00:03:38.159 --> 00:03:43.280
prevents us from putting a CPU on top of this thing and accidentally having it

00:03:41.519 --> 00:03:47.040
rock back and forth and chip off a corner or something like that now let's

00:03:45.040 --> 00:03:53.040
have a look at some of the CPU options that are available here uh we've got a

00:03:50.080 --> 00:03:56.560
core i7 7820hk that should actually be an overclockable

00:03:55.040 --> 00:04:02.000
chip i'm going to want to try that one for sure next up we've got a whatever

00:03:58.640 --> 00:04:06.400
this is and uh whatever this is so these

00:04:02.000 --> 00:04:08.400
are apparently a ql2x and a ql3x so

00:04:06.400 --> 00:04:13.680
these are engineering samples that never got formal names so one of them runs at

00:04:11.040 --> 00:04:18.560
2.4 gigahertz based 3.5 gigahertz boost and the other is 2.7 base 3.8 boost and

00:04:16.799 --> 00:04:25.120
apparently both of them will overclock in the range of 4.2 to 4.6 gigahertz and

00:04:23.120 --> 00:04:30.960
stay there so these are unlocked chips and you can get them for as little as 80

00:04:28.160 --> 00:04:36.240
to 90 dollars which i guess reveals the whole point of all of this which is that

00:04:33.759 --> 00:04:41.280
if you happen to have an old z170 motherboard or something similar and you

00:04:39.280 --> 00:04:45.199
want a whole lot of performance for not a lot of money this could be a very

00:04:43.440 --> 00:04:50.880
interesting way to do it the last chip that we've got here appears to be a 7700

00:04:48.160 --> 00:04:55.840
hq and this is a qualifying sample so most of the cpus we've got are not

00:04:53.360 --> 00:04:59.440
legitimate cpus that were pulled off of boards these are like

00:04:57.199 --> 00:05:02.960
qualifying and engineering samples so this this whole

00:05:01.199 --> 00:05:07.280
thing we're doing is super duper condoned by Intel i'm sure i actually

00:05:05.520 --> 00:05:11.199
have no idea what's pre-installed in the board here so we'll find that out soon

00:05:09.120 --> 00:05:14.639
enough first i want to just make sure it's working at

00:05:12.800 --> 00:05:19.919
all so you're going to notice that i put a very very small amount of thermal

00:05:16.800 --> 00:05:21.919
compound on here that's because the dye

00:05:19.919 --> 00:05:26.800
is very very small we don't need to cover a whole lot of surface area now

00:05:24.560 --> 00:05:31.600
mr sue claims that with this mounting shim here you

00:05:28.960 --> 00:05:35.039
can actually install just a normal freaking

00:05:32.639 --> 00:05:38.400
Intel stock cooler so i think that's the first thing we're going to try i'm going

00:05:36.639 --> 00:05:43.840
to be really interested to see what the BIOS reports about this thing

00:05:40.960 --> 00:05:48.000
we ready for the magic moment our RGB RAM is lit up we basically have

00:05:45.919 --> 00:05:51.919
all the functionality we need now let's see if we can get into the BIOS

00:05:49.440 --> 00:05:56.160
here f2 delete this doesn't appear to list

00:05:53.039 --> 00:05:58.800
a CPU model anywhere in here

00:05:56.160 --> 00:06:03.600
yes so we are unlocked ah

00:05:59.680 --> 00:06:05.520
here we go oh so this is a 6700 hq why

00:06:03.600 --> 00:06:09.520
would that be unlocked that shouldn't be unlocked

00:06:07.440 --> 00:06:13.919
okay so why don't we throw one of our well first let's get into Windows let's

00:06:11.440 --> 00:06:17.840
get some hardware info fired up here everything seems to be working

00:06:15.280 --> 00:06:22.240
relatively normally there it is 6700 hq running just like you would

00:06:20.960 --> 00:06:28.400
expect now as expected the CPU is running

00:06:24.560 --> 00:06:30.720
really cool like 19 to 22 degrees at

00:06:28.400 --> 00:06:36.880
idle let's go ahead and just throw a quick blender render at it and see

00:06:33.600 --> 00:06:40.400
how it looks after that even this

00:06:36.880 --> 00:06:42.639
pinner Intel stock one on it under load

00:06:40.400 --> 00:06:46.000
we're looking at 45 degrees celsius so i think it's pretty safe for us to crank

00:06:44.080 --> 00:06:50.479
that multiplier up to the maximum it'll reach and let's see what our performance

00:06:48.319 --> 00:06:54.240
looks like as it is we're turboing to just 3.1 gigahertz on all course i think

00:06:52.880 --> 00:06:59.680
we can do better all right so as expected yes that 35

00:06:56.639 --> 00:07:02.160
multiplier is indeed the max single core

00:06:59.680 --> 00:07:06.000
turbo frequency of this particular chip we're just going to see if we can hit

00:07:03.599 --> 00:07:10.080
that all course now i have no experience trying to overclock Intel's locked

00:07:07.680 --> 00:07:14.960
mobile chips even just to run all cores at the single core boost frequency

00:07:12.479 --> 00:07:20.160
because even if Intel did allow this kind of behavior uh no mobile you know

00:07:17.919 --> 00:07:22.880
device manufacturer in their right mind would allow you to do that

00:07:21.759 --> 00:07:26.720
kind of thing because you would overwhelm the cooling and i guess i have

00:07:25.039 --> 00:07:30.639
no more experience than i did before because as you can see here it doesn't

00:07:28.560 --> 00:07:34.960
work we're still running at 3.1 but that's okay because between the

00:07:33.120 --> 00:07:39.599
qualifying samples the engineering samples and the straight up k series

00:07:37.759 --> 00:07:43.039
unlocked chips we can still do some overclocking today so i was actually in

00:07:41.360 --> 00:07:48.319
the middle of swapping cpus and i realized that we haven't actually seen

00:07:46.479 --> 00:07:52.080
under this thing yet so let's have a look at what if anything mr

00:07:51.199 --> 00:07:56.160
su has modified about this motherboard here

00:07:54.720 --> 00:08:00.400
yeah it looks like not really anything all they've done is remove the normal

00:07:59.039 --> 00:08:03.759
mounting plate here you know it would have that little that little lever and

00:08:02.560 --> 00:08:09.520
all that kind of stuff so they've just removed that and then the CPU

00:08:08.080 --> 00:08:13.759
is held in by the hold down plate or the shim up

00:08:11.599 --> 00:08:16.879
here this shim that came pre-installed seems to be like a pre-production one or

00:08:15.520 --> 00:08:22.160
something because it looks like it actually has some um some sanding marks on the top like

00:08:20.560 --> 00:08:26.800
they were trying to dial in the height just right so we're going to do

00:08:25.520 --> 00:08:30.800
away with that one we're going to use one of the one of the finished samples

00:08:28.720 --> 00:08:33.440
here uh what CPU to want to go for alex do you want to go for one of the mystery

00:08:32.080 --> 00:08:37.839
meat ones or do you want to go for the 7820 hk the expensive one pick a hand

00:08:36.479 --> 00:08:41.839
that one okay we're going with this one no just

00:08:42.640 --> 00:08:49.600
if it's a little looser i think than a real CPU i mean i shouldn't say

00:08:47.680 --> 00:08:53.440
it's not a real CPU it is a real CPU it's a little looser than one that you're

00:08:51.680 --> 00:09:00.000
supposed to put oh wow that's interesting uh okay so when i removed

00:08:56.399 --> 00:09:00.000
the mounting plate before

00:09:00.080 --> 00:09:07.200
i heard a plank that's what that was so here's our original back plate here

00:09:05.040 --> 00:09:10.480
so i'm going to have to hold that on while i install the CPU so it's a little

00:09:09.200 --> 00:09:14.880
jankier that's okay back in my starving student

00:09:12.800 --> 00:09:19.200
days i would have easily put up with this much jank to save like 100 bucks or

00:09:17.519 --> 00:09:22.959
whatever just a little bit of thermal compound

00:09:21.360 --> 00:09:27.519
now you really don't need a lot on these bare dyes look at that even the amount i put on

00:09:26.160 --> 00:09:30.160
before almost all gooped up around the edges

00:09:29.200 --> 00:09:35.440
there the good news though is that means that our mounting pressure was pretty darn

00:09:33.760 --> 00:09:39.279
spot on which means the height of their adapter is about right

00:09:43.760 --> 00:09:51.240
oh turned off turning back on probably memory training

00:09:48.160 --> 00:09:51.240
or something

00:09:53.279 --> 00:09:58.959
nothing yet so here's one thought remember how i

00:09:56.959 --> 00:10:01.680
said i really wasn't sure how tight it was supposed to be because there doesn't

00:10:00.320 --> 00:10:05.279
seem to be any kind of stopper to prevent you from going ham on this thing

00:10:03.839 --> 00:10:09.760
i'm gonna try backing it off a little bit and making sure that the tension feels

00:10:07.839 --> 00:10:13.340
kind of even you know okay let's try that

00:10:13.839 --> 00:10:18.720
so that didn't help what i'm gonna do is i'm gonna grab the other one the one

00:10:17.120 --> 00:10:23.560
that was in my right hand we're gonna give that one a shot

00:10:20.399 --> 00:10:25.279
LTT shirts also a thermal paste wipe

00:10:23.560 --> 00:10:29.680
lttstore.com to be clear i'm not actually recommending rubbing a shirt all over a

00:10:28.000 --> 00:10:33.680
CPU it's just my cameraman wants to go home on time

00:10:31.360 --> 00:10:36.800
okay bowser has been reset beautiful all

00:10:35.600 --> 00:10:42.720
right let's have a look at what we got here so this little puppy runs at 3.4

00:10:40.720 --> 00:10:46.200
right out of the box so what does that make it then

00:10:48.079 --> 00:10:55.680
not sure oh this is the boring one this one's

00:10:52.800 --> 00:10:59.600
locked okay swapping cpus again i gotta say the review sample ones really look

00:10:58.079 --> 00:11:03.360
like they've been through hell and back this one has what appears to be glue or

00:11:01.680 --> 00:11:08.640
something or thermal compound on the bottom of it so we had assumed the two green ones

00:11:06.640 --> 00:11:13.279
were like the weird engineering sample ones and then the blue one was not but

00:11:11.120 --> 00:11:17.680
that turned out to not be the case so what i'm really hoping is this is

00:11:15.839 --> 00:11:24.560
going to be the qx 2 engineering sample because that one's

00:11:20.240 --> 00:11:25.519
apparently good for 4.5 to 4.6 gigahertz

00:11:24.560 --> 00:11:30.959
um well that ain't a good sign i mean it posted hey

00:11:32.000 --> 00:11:40.000
oh interesting yes so mr sue's associate

00:11:36.640 --> 00:11:41.680
who sent us over these cpus had informed

00:11:40.000 --> 00:11:47.600
us that they might be a little touch and go when it comes to pci express gen 3.

00:11:44.480 --> 00:11:50.320
we might want to change our pci express

00:11:47.600 --> 00:11:54.079
slots to gen 2 to avoid some complications with the NVIDIA driver so

00:11:52.640 --> 00:11:58.880
we're going to go ahead and try that but first i want to know what chip this is

00:11:56.079 --> 00:12:03.360
and we don't know oh bummer i think this is the slower one of the two engineering

00:12:00.800 --> 00:12:06.560
samples ah man they're not labeled i'm having a hard time keeping track of

00:12:04.640 --> 00:12:10.000
which ones are which hey there we go we're in Windows now

00:12:08.079 --> 00:12:12.320
heck yeah uh

00:12:13.760 --> 00:12:16.240
hacking

00:12:17.760 --> 00:12:24.040
you know what why don't we dial in the overclocking settings that they recommended here

00:12:24.880 --> 00:12:30.480
yay all right 4.2 gigahertz let's go ahead and do a

00:12:29.360 --> 00:12:35.519
quick uh stress test so it is a disadvantage to run at pci

00:12:33.680 --> 00:12:39.839
express gen 2 but not a huge one unless you're running

00:12:37.920 --> 00:12:43.519
some kind of like compute application on your graphics card now what is a problem

00:12:41.440 --> 00:12:46.639
is if you go to run a stress test and your system restarts kind of like that

00:12:45.440 --> 00:12:52.079
but uh yeah so that's engineering sample cpus for you

00:12:50.560 --> 00:12:56.560
all right so we're pretty close to water cooling the 78 20 hk but

00:12:54.800 --> 00:13:00.720
before we do that i want to try that one that wouldn't post one more time it's

00:12:58.639 --> 00:13:04.160
possible it just bricked itself while i was

00:13:01.680 --> 00:13:08.079
touching it it's also possible it just we didn't get a good mount so oh boy

00:13:07.200 --> 00:13:12.720
wow oh wow the the reset button isn't

00:13:11.279 --> 00:13:16.639
working wow hey

00:13:15.760 --> 00:13:21.040
oh it's off hey

00:13:19.279 --> 00:13:25.040
oh it's off so what we're going to do then is we're

00:13:22.320 --> 00:13:30.320
going to move on to our proper like real CPU our 7820hk which does happen to be

00:13:28.000 --> 00:13:35.600
the most expensive one out of the bundle but it's also the only one that is

00:13:32.480 --> 00:13:37.040
legitimately unlocked and overclockable

00:13:35.600 --> 00:13:41.360
something i haven't mentioned up until now is that motherboard compatibility

00:13:38.959 --> 00:13:44.839
with these cpus is not a guarantee there are a handful of chip sets including

00:13:43.360 --> 00:13:51.680
h310 z390 that would be compatible with 7th

00:13:48.480 --> 00:13:54.880
gen desktop chips but that will not work

00:13:51.680 --> 00:13:57.120
with these even with a modded BIOS and

00:13:54.880 --> 00:14:00.639
as i am now coming to if you want your motherboard to work even if it has a

00:13:58.720 --> 00:14:07.600
compatible chipset you will need a modified BIOS which mr su says will be

00:14:04.320 --> 00:14:09.519
available to download at some point

00:14:07.600 --> 00:14:12.959
code c1 again i wonder if it is to do with tightness

00:14:11.279 --> 00:14:17.320
in the socket maybe i overcooked it a little this time

00:14:18.720 --> 00:14:23.920
needs a fidget spinner we have a screwdriver

00:14:22.320 --> 00:14:27.440
hey nice

00:14:25.600 --> 00:14:31.839
system experience to boot failure blah blah blah load optimized defaults all

00:14:29.920 --> 00:14:35.920
right so we've got our 7820hk all our RAM is detected everything is looking

00:14:34.560 --> 00:14:38.320
perfectly normal

00:14:42.720 --> 00:14:50.240
now we're on a2 okay so we did an isopropyl alcohol wipe

00:14:48.000 --> 00:14:55.519
on the bottom of the CPU just to make sure the contacts were all good and it

00:14:52.320 --> 00:14:55.519
does seem to be booting now

00:14:55.680 --> 00:15:01.360
come on baby come on

00:14:59.199 --> 00:15:05.600
just just boop max link speed okay so we're

00:15:03.680 --> 00:15:09.120
already at gen 2 i don't know why don't we try

00:15:06.880 --> 00:15:15.760
gen 3 then who knows i wonder if it has something to do with our m.2 storage

00:15:12.079 --> 00:15:18.800
let's just just try stuff

00:15:15.760 --> 00:15:20.560
hey we're in all right so now we're

00:15:18.800 --> 00:15:24.800
looking good let's make sure this bmw render runs at stock speed then we can

00:15:23.040 --> 00:15:30.880
overclock this puppy oh we'd be blending slow what is this

00:15:27.760 --> 00:15:33.519
what is this speed yuck

00:15:30.880 --> 00:15:40.000
screw it let's overclock it so challenge number one we're uh hitting right off

00:15:36.720 --> 00:15:42.720
the bat here is that our xc7 water block

00:15:40.000 --> 00:15:47.120
has pre-applied thermal compound in a uh

00:15:44.959 --> 00:15:51.440
on a much larger patch than we're going to need for our processor so we're going

00:15:49.199 --> 00:15:55.120
to open by just cleaning off all of our thermal compound and

00:15:53.040 --> 00:15:58.800
using something much smaller so what's cool about this mounting mechanism is

00:15:56.720 --> 00:16:03.199
that on both the bottom and the top it doesn't interfere with using a

00:16:00.639 --> 00:16:06.800
completely normal cooler in any way so i can just go ahead and

00:16:05.199 --> 00:16:11.040
chuck my water block on here and i should be pretty much good to go

00:16:09.040 --> 00:16:14.880
all right well i don't think this is either mine or alex's finest wiring or

00:16:13.279 --> 00:16:19.120
plumbing job but uh we're going for performance not

00:16:17.040 --> 00:16:21.360
looks here all right let's see if i got the

00:16:20.240 --> 00:16:24.160
plumbing the right way around

00:16:25.680 --> 00:16:31.920
that's what a non-lubricated pump bearing sounds like

00:16:29.839 --> 00:16:36.079
for the uninitiated get that air bubble out of there what are you doing

00:16:34.079 --> 00:16:38.560
dang it i got the radiator actually oh i got the whole thing the wrong way around

00:16:37.600 --> 00:16:43.920
well realistically it won't make much difference this thing is like a 45 watt

00:16:41.600 --> 00:16:47.360
CPU should we turn it around no we should probably turn it around i

00:16:45.839 --> 00:16:51.519
don't think you need to we should probably turn it around it's going through the CPU block backwards do

00:16:50.560 --> 00:16:55.120
you think it's going to make any difference a couple degrees

00:16:53.759 --> 00:16:59.680
you know what no we're doing it we're turning it around uh we didn't think

00:16:57.279 --> 00:17:02.959
this through okay so here's the plan yeah you're pulling pinch all plugged

00:17:01.120 --> 00:17:07.760
okay but what about this hole well that was fine okay ready

00:17:04.799 --> 00:17:07.760
three two one

00:17:09.199 --> 00:17:11.439
shoot

00:17:15.679 --> 00:17:21.199
oh that's so many trees

00:17:19.120 --> 00:17:25.280
okay now we're going the right way for the loop to actually

00:17:23.039 --> 00:17:29.439
bleed and the performance to be right that was worth it totally worth it

00:17:29.440 --> 00:17:36.400
so apparently this chip will do about 4.6 gigahertz 1.3 volts all cores let's

00:17:34.320 --> 00:17:38.640
see if it'll do it underwater wow

00:17:37.440 --> 00:17:42.880
sure didn't so we're stable in Windows or

00:17:41.200 --> 00:17:47.440
we are booted to Windows stable is a strong word we're at 4.4 gigahertz had

00:17:45.679 --> 00:17:51.919
to back it off a little bit let's go ahead and try a quick stress test and

00:17:49.679 --> 00:17:55.520
see if this is actually working are we thermal throttling or thermal

00:17:54.080 --> 00:18:01.120
throttling did you take the sticker off the bottom

00:17:58.160 --> 00:18:04.559
yes i did

00:18:02.559 --> 00:18:09.840
so you can see that our shim actually

00:18:07.360 --> 00:18:14.320
interfered with us getting good contact between our CPU block and our processor

00:18:12.799 --> 00:18:18.400
something a lot of people don't know is that thermal paste is actually not a

00:18:16.480 --> 00:18:24.240
great conductor of heat all it's meant to do is fill in like micro gaps between

00:18:22.000 --> 00:18:28.400
the the two pieces of metal so when you actually have like a thick

00:18:26.400 --> 00:18:32.400
layer of paste in between you get very very poor thermal transfer so i'm not

00:18:30.240 --> 00:18:35.200
100 sure how to solve this problem maybe we could see if it's down to

00:18:33.520 --> 00:18:39.600
manufacturing tolerances and try a different shim i mean even just to the

00:18:37.760 --> 00:18:45.520
eye it looks like it's a little below

00:18:42.960 --> 00:18:49.360
i wonder if it's relying on a cooler design kind of like the stock cooler you

00:18:47.520 --> 00:18:52.960
see here how the slug at the bottom is actually slightly raised compared to the

00:18:51.360 --> 00:18:57.280
aluminum fins that puts quite a lot of pressure Corsair's water cooler by

00:18:54.720 --> 00:19:03.919
contrast is exactly flat so we remounted the CPU and

00:19:01.280 --> 00:19:08.240
it's not booting now honestly it doesn't matter anyway though because this is

00:19:05.679 --> 00:19:13.600
clearly very poor contact again what we're going to try and do is use

00:19:11.840 --> 00:19:17.039
the one that came pre-installed on the board okay so i'm just going to throw

00:19:15.440 --> 00:19:21.919
that on there and then see if we get oh that's so much better look at that okay

00:19:20.000 --> 00:19:25.679
i'm expecting much better results this time assuming it actually posts

00:19:24.480 --> 00:19:30.240
okay this is it this is go time

00:19:28.559 --> 00:19:36.640
and you know what we're gonna go straight to 4.6 gigahertz

00:19:34.320 --> 00:19:39.919
hey we got into Windows this time turns out having a functioning cooler is a

00:19:38.400 --> 00:19:45.520
good idea how about that what do you what do you know

00:19:41.720 --> 00:19:48.400
4.6 gigahertz there it is interestingly

00:19:45.520 --> 00:19:51.520
one of our CPU cores isn't reporting temperatures let's fire up a blender

00:19:50.480 --> 00:19:55.910
render bloop and it's gone let's try that again

00:19:54.880 --> 00:19:59.579
and

00:20:00.240 --> 00:20:07.200
it's back no it's gone blender's just gone we're gonna we're gonna drop the

00:20:04.640 --> 00:20:11.840
frequency a little brb tornado let's see if our rendering program

00:20:09.520 --> 00:20:16.640
manages to stick around with uh and it's gone

00:20:14.240 --> 00:20:20.640
we're going to dial back the frequency okay

00:20:17.520 --> 00:20:22.720
4.5 gigahertz let's try that again hey

00:20:20.640 --> 00:20:27.360
that's more promising wow

00:20:24.320 --> 00:20:30.320
hottest core 47 degrees

00:20:27.360 --> 00:20:35.039
coolest core 25 degrees that's the thing about having a bear die is like very

00:20:32.720 --> 00:20:38.400
slight difference in the mount can make a really big difference performance

00:20:37.039 --> 00:20:43.200
looks like it's getting a very significant uptick look at this render

00:20:40.720 --> 00:20:46.880
chug along here this is great of course if what we were after was 3d

00:20:45.039 --> 00:20:50.000
rendering oh yeah we might need to do the graphics

00:20:48.240 --> 00:20:55.039
drivers here of course if we were going to be rendering all day and we had 150

00:20:52.240 --> 00:21:00.320
dollars to spend we would just go for uh core i5 8400 or something like that with

00:20:57.919 --> 00:21:06.000
six cores the only reason we'd want a quad core that's higher clocked would be

00:21:02.720 --> 00:21:09.039
for gaming so how's the experience there

00:21:06.000 --> 00:21:10.640
then well it's fine i guess

00:21:09.039 --> 00:21:14.880
uh we did have to drop the frequency down to 4.4 in order to get it

00:21:12.960 --> 00:21:21.760
completely stable in game but i think the overall problem that we're

00:21:17.840 --> 00:21:24.720
running into here is that the benefits

00:21:21.760 --> 00:21:30.000
of a solution like this simply do not outweigh the drawbacks at this time

00:21:27.600 --> 00:21:34.880
we're paying 150 bucks which means for less than that we could pick up a 6700k

00:21:32.960 --> 00:21:38.159
or something like that on ebay for even less or

00:21:36.240 --> 00:21:43.679
we are really rolling the dice as we experienced with those unnamed zero zero

00:21:41.280 --> 00:21:47.120
zero zero cpus where we're potentially getting a great value or we're ending up

00:21:45.520 --> 00:21:50.960
with something that's not going to be particularly usable for us now if you're

00:21:48.960 --> 00:21:54.720
the kind of person who likes to tinker you've got a motherboard that happens to

00:21:52.960 --> 00:21:59.280
be compatible with the BIOS mod lying around anyway and you just want to like

00:21:56.799 --> 00:22:03.679
have some fun and maybe take something that is currently non-functioning and

00:22:01.360 --> 00:22:10.000
get a decent little gaming rig out of it for 70 or 80 bucks with a weird CPU

00:22:06.799 --> 00:22:11.600
upgrade hey recommended but

00:22:10.000 --> 00:22:14.400
it just isn't the kind of thing that personally i would daily drive and i

00:22:13.679 --> 00:22:19.679
think alex is on the same page over there yeah

00:22:18.000 --> 00:22:25.120
you know what i would daily drive though the massdrop x bayer dynamic dt177x go

00:22:22.960 --> 00:22:28.480
headphones are made by the renowned german manufacturer

00:22:26.480 --> 00:22:33.440
bayer dynamic they feature a closed back design their latest generation of 45

00:22:30.960 --> 00:22:38.000
millimeter tesla drivers a wide frequency range and weighty controlled

00:22:35.760 --> 00:22:42.720
base these are a favorite for recording studios and they're easy to drive from

00:22:40.159 --> 00:22:46.640
portable sources without an external amp they feature a durable design with

00:22:44.159 --> 00:22:51.280
aluminum earcups a spring steel headband and metal yokes and hinges and you can
