today is a good day because I have everything I need 230 L of liquid
nitrogen this rotten apple this giant hunk of copper these tongs the one and
only Alan spave gers such current world record holder for 12900 K and 12900 K
overclocking and of course this map gas torch what are we going to be doing with
them we are going to be overclocking why you ask I'm glad you did because it's
the day of Our Lord June the 9th and we
desire a 6.9 G gz CPU nice like this
message from our sponsor ug green make charging more convenient with ug Green's
new 65 W charger it's a 3in1 charger that has two USBC ports and a USB a port
in a super compact form factor that fits in the palm of your hand get yours today
using the link down below step one get liquid nitrogen from this through the
phase separator into this
woo it's freaking me out guys how do we
tell how full it is we can't see a thing also my hand's very cold he why do you
drive a Subaru stranger things how you doing
there hosie boy the next step is obviously to play with it for a bit what
is it a minus 195° yeah the fact that it's still
boiling around the apple means it's not quite Frozen through yet right you got it drink your
juice all right come on banana buddy
okay ah you should probably put on some
safety glasses you'd hardly even believe that was a
tangerine once I guess we should get to work now
huh watch out watch out God oh wait it
it broke through whoa our buckets leaking crap this is where it was
sitting on the floor yeah the epoxy that's there I guess froze with that out
of the way let's fill up a more reasonable sized container from lpt
store.com and talk about why we want liquid nitrogen for overclocking at all
woo see the thing about microprocessor is the faster you run them that is more
gigahertz the more heat they generate and as they get hotter their internal
resistance goes up generating you guessed it even more heat this creates a
kind of hard barrier to how fast you can go that's why we don't have 10 GHz CPUs
today but what if you could remove all
of that heat as efficiently as possible say take it down to greater than
170° C well that's where this buddy comes in but it's not as simple as just
taking your CPU plunking it into the motherboard and dumping liquid nitrogen
on it for reasons that you might not necessarily think of it's not the liquid
nitrogen that I'm putting on this board that has a chance to kill it it's
actually the moisture in the air around us you see as that moisture contacts my
cold board is going to condensate or turn into liquid water which as you guys
can imagine having sitting on a motherboard is a pretty bad time things
like closed cell foam dialectric grease artist eraser and shop top towels are
great tools to keep air and therefore moisture away from your sensitive
Electronics however this particular board which was prepared by spave is
using a technique that I haven't seen before it looks almost like a conformal
coating what is this this is a liquid electrical tape oh I ruined too many
clothes with Vaseline okay fair enough now the key knite among our viewers have
probably noticed that you didn't just blanket the whole board in electrical
tape and in fact it seems to be built up in thicker layers in certain areas
obviously you don't want any moisture in your vrms with the kind of current
you're going to be running through there it would Arc much more easily but can you explain the rationale behind why you
might say coat the audio chipset but not
coat the motherboard PCH the motherboard PC is going to be pretty warm as it is
and when I don't run a cooler on it to let it get warm so it kind of acts as a
defroster in this area and then would that be the same thing for the bottom of
the board here or yeah it won't really get this far but a heat backboard heater
and the chipset and the vrm will'll keep it pretty defrosted printed circuit
boards are made of copper and copper as you guys know is an excellent conductor
of heat and also cold so if we put something really cold here it's
conceivable that if we didn't have other heat sources on the board this entire
thing would get really cold really fast
that's a heater oh I see how fun is this
this is a giant freaking CM thick
thermal pad delicious and under it is what is this
an eot who makes this Elmore Elmore is another famous overclocker and you guys
are all you guys are all bitter enemies Yeah so basically all I'm really looking
at here is pretty much the same thing you'd find on your rear car window for
defrosting it's just High Resistance wires on a PCB so you just use a simple
six pin PCIe and then it basically just goes yep Heat this boy up the next
weapon in the extreme overclockers Arsenal that I am familiar with is of
course the pot now these can be designed for various substances dry ice liquid
nitrogen liquid helium I would imagine you use pretty much the same design for
helium and nitrogen and these are not just a hunk of copper they are
specifically engineered to optimize the transfer of heat from your CPU to the
liquid that is boiling within it now as you can imagine mounting one of these is
not as simple as just you know putting a normal mount bracket on it because
you've been paying very close attention any brackets or metal pieces around the
CPU are going to collect condensation so
we actually use a very specific way of mounting these with extremely long posts
on our thermal padded heated back here and all of our Hardware way up here so
that we can wrap it all up in shop towel and make sure that any condensation that
does inevitably gather is going to be absorbed by that and that's it Yeehaw
I'm a professional overclocker right ladies and gentlemen well no actually
isn't how it works see this probe right here this is a k type probe plugs into
one of these you don't just want the CPU running as cold as possible and managing
The Thermals of the chip are a huge part of the art SL science SL Blackmagic that
is Extreme overclocking you see for example some chips or or even entire
platforms might have a bug say for example where if they're too cold when
you first try to boot them they won't turn on at all you got to start them
warm then cool them down or vice versa that means just as important as our
application of cold is our application of heat we also need the knowledge any
idiot could pour L2 on a CPU and overclock higher than they would be able
to on air or water cooling but to reach
the absolute limits you've got to invest in both your own knowledge and personal
experience something that can only be gained through countless hours spent on
this stuff and in building connections none of those are things that you can
buy for any amount of money but that doesn't mean it's a cheap hobby no one
even with years decades of experience could hope to achieve a world record
overclock without what we call a Golden Chip as we also learned in our Intel Fab
tour every piece of silicon is a little bit different and not all have the same
capabilities the one that I'm holding in my hand is the result of buying 100 of
Intel's 12900 K and taking only the top
10 of those with one of these you might
have a chance but let me get this out of the way for you there is absolutely no
money in extreme overclocking whatsoever very true and the folks who do dedicate
their lives to it do it for the thrill of the hunt so with that in mind let's
get the fourl over with and overclock some CPUs is this one going to do 6.9 I
know we can do it that's what a whole gigahertz lower than what you've done on these pretty up there still but it
should be should be okay oh he's changing his tune already so now when
now when he doesn't do it well I didn't say for sure actually you won that yeah
oh really yeah small world hilarious what's a safe voltage that I can
actually I'll just guess well we'll just see what happens I'll just go if
you got the defaults you have the RGB
where you want it turbo performance yay
we did it what I'm really curious about now is just how fast this will go with
liquid nitrogen and just stock settings like XMP just enable the power limit to
go as high as it wants the highest that I've ever seen on an Intel CPU like this
air cooled is about 28
29,000 in cinch show negative
temperatures zero yeah 0° yes oh weird
but it only Drew 160 Watts even though
it was 4.9 allor so that could be due to our colder temperature oh like it's that
big cuz I would normally expect that to be like 300 and a bit watts do you want
to try to go colder and see if we can get even less wattage well I want to
open up XTU first and see what we can get sure it should be pretty happy at
like 42 there we'll just take all of these to five and we need some more
voltage po voltage offset let's do .12
sure I'm just guessing numbers that's all I
do didn't blue screen wow you a pro so L
and2 is just like easy mode we're drawing 230 watts and I would expect
this to normally be like 400 yeah all
right here broke 30,000 points and C a bench right there that's what faster
than a Threadripper 32 core yeah and we're only atus
90 compared to that stupid Chiller that we have oh my God all right let's just
try 6 GHz there's no way this just a 6 GHz like that oh my God it's doing it
how 6 GHz on all the Pees it's only 260
Watts this is insane below your typical wattage at 6 GHz holy crap 3,200,000
points in cin bench just did it it's like the black hole Yeah it's just
completely black this can't read below -40° C is there any hot spots on the
board it's it's having a lot of trouble with a thing that's that cold around
here it's confused chipsets at 40° SSD
is at 47 well let's uh apply 6.4 and see
if it crashes it's not fine I have more CPUs we can
use no way it just do 6.4 oh it didn't
you could do one thing turn off C States and you could put it on fixed voltage or
saying fix the voltage normally you would have a VF curve so the more
frequency that you want the More Voltage it gives it we don't care about that at
all we're just sticking one voltage cuz we're going for just the highest point
on that VF curve and that's the only one that we care about you wouldn't want to run your system like that the voltage
kind of erodes away your silicon and uh it it won't be very happy in a while but
if you're just doing stuff like this it's totally fine so about like 1.45
sure 1455 sure uh let's try 6.3
6.3 GHz and that's just with me not even
trying in XTU this is amazing 3500
points in cinn bench oh my God we just beat a Threadripper
3960x if I don't even need your help to get 6.9 that would be amazing I think I
will will it do 6.5 is this going a lot
better than I thought it would oh do we freeze no never mind all right well do
you want to take over sure you can go further I'm going to set like a basee
core frequency of 55 uh like 42 on the
EES just give us some voltage so it's
booting a little warmer and I'm going to turn C States off so it's always at its
highest level okay there water on top of the memory is that good yeah not optimal
but I I think it'll be all right okay so what we're doing right now is retraining
the memory apparently it isn't too happy when you're below what 140° C so he just
just changed one setting incredibly slightly filled the pot dumped it down
to what is this 193° C then you just
restart it and the memory retrains itself and apparently is fine afterwards
it's fine okay uh 162 1.62 volts you
told me to stop at 1.5 I didn't want you to beat me do you want to go for it sure
yeah go for it it's a 69 wo 6.9 yep we can see it in the thing
let's open up to task manager oh task manager's dead window doesn't know what
to do with any of this oh my God it's doing it I think the beginning is
usually the hardest part so should be all right and we're getting as warm as
188 boom holy crap we did it 6.9 GHz CPU
we did it nice that wasn't even hard
that was easy sorry do you want to do a base clock
over clock oh sure 6969 yeah 6969 I'll go grab lonus and this is where it goes
AR you hear a little pop and thermal pace is gone
y so we had a catastrophic failure there
so I have to torch it up two around 150
it'll should come back it's it's just a black hole still
what if you go like this
ready watch my eyebrows do you see our IO is all oh
jeez that can't be good why is it so wet I don't know have you used this stuff
before lonus no it's amazing I got what 6.3 GHz no problem it only Drew like 240
WTS too it's like within Intel's TDP wow it's insane what are we at right now 6.9
4.2 oh it passed beautiful
36,000 that is absolute Madness I have
the scores right here like hold on a second so that's what you'd expect out
of an epic server CPU with twice as many
cores yeah literally double wow does
that ever boil fast boy you must go through a crap ton of this stuff you
want to hear underload it gets even low I
do we went through like this much just to run that one Benchmark so what you're
saying is that if I were to try and do this 24/7 it would cost an astronomical
amount of money half a liter a run maybe
no it seems that 12900 K just handles cold really well and you just freaking
go for it we could go colder it would be even better really can we do more on
this chip yeah we can bump it up and see where it fails holy crap did we ever
boil away a lot on that one was there more power we hit
38.5k now so the eor has Juiced the
score quite a bit 1,500 off the world record for a 16 cor core I9 so give it
more I guess is pouring the L and2 considered a glamorous job or is that
like the monkeyy job we call it the ln2 bit but not when you're doing it at
least not to my face right it's boiling so hard it's like slopping out of the
thing here oh we hit a blue
screen so why is it only the start that it doesn't like super cold I think it's
kind of like when it's on it's not as
cold oh cuz like the actual CPU isn't getting down to like0 cuz it's right
running and making heat got some wattage in it woo when you find a Golden Chip I
mean do you try and get as much juice out of it as soon as you can knowing
that what you're doing to it is going to degrade it significantly as long as
you're careful careful yeah this looks really
careful woo you have until my dunk CPU hits room
temperature to break a record ready go actually it's worse than that you have
until my hand gets too cold to hold this all right I already
failed you know who never fails our sponsor MSI looking for a GPU for your
next build guess what you can actually buy them now haha check out the MSI RTX
370 TI Ventus 3x8 gooc it's powered by
NVIDIA's ampure architecture and has 8 gigs of gddr6 memory with Boost clocks
up to 18800 MHz it's got three DisplayPort 1.4 a ports and an HDMI 2.1 Port
plus three of their Torx 3.0 fans coupled with a beefy heat sink to keep
your temperatures low their zero frozer technology turns your fans off while the
system is not underload and a custom brush metal back plate helps provide a
clean look on top of all that it has a three-year warranty you can learn more
at the link down below if you guys want to know if this still works we're going
to have a Floatplane.com exclusive where we find out the answer could very
well be no I legitimately don't know if you enjoyed this video you guys can
follow spave and his exploits at the links down below and if you're looking
for something else to watch maybe check out our most extreme air cooled PC yeah
where we hooked a computer tower up to the most powerful fan we could find and
a wind tunnel it was pretty dumb yeah
