00:00:00.240 --> 00:00:06.879
okay so when we were building our wall pewter wall computer well pewter get it

00:00:04.880 --> 00:00:13.040
anyway one of the challenges was having the graphics card on the opposite side

00:00:10.080 --> 00:00:19.840
of the frame versus the motherboard i mean this thing was so far away that

00:00:16.400 --> 00:00:22.160
there wasn't a single pci express riser

00:00:19.840 --> 00:00:24.880
cable on the market that was able to reach

00:00:23.039 --> 00:00:31.599
so the solution use more pci express risers we actually

00:00:28.480 --> 00:00:33.360
ended up with a one meter thermaltake

00:00:31.599 --> 00:00:38.960
premium extender chained to a 30 centimeter one and we

00:00:37.040 --> 00:00:43.360
pulled it off with no performance degradation whatsoever the system worked

00:00:41.840 --> 00:00:48.960
perfectly fine which got us thinking

00:00:46.559 --> 00:00:53.920
just how far can you go

00:00:50.559 --> 00:00:56.480
before things go haywire

00:00:53.920 --> 00:01:01.440
stick around while we uh snake our way

00:00:58.399 --> 00:01:09.680
to the conclusion

00:01:09.680 --> 00:01:16.560
browse privately and securely with tunnelbear the simplevpn app start your

00:01:14.640 --> 00:01:20.080
seven-day free trial at the link in the video description

00:01:18.159 --> 00:01:25.759
okay so to kick off the experiment we rigged up our standard GPU bench machine

00:01:23.119 --> 00:01:31.360
so it's a known good machine our pci express signal integrity should be about

00:01:28.799 --> 00:01:38.880
as good as it can get then we needed an extra piece so we also hooked up a

00:01:34.320 --> 00:01:41.280
separate power supply for our gtx 650 ti

00:01:38.880 --> 00:01:46.479
graphics card this is so that we don't actually run into power cable length

00:01:43.840 --> 00:01:51.280
limitations if the experiment goes completely off the hook

00:01:48.720 --> 00:01:56.000
also having an excuse to call out to ivan like he's far away is a

00:01:53.280 --> 00:02:00.320
is a bonus so uh hit the power switch chekov

00:01:57.200 --> 00:02:01.840
so i did catch that can you repeat

00:02:00.320 --> 00:02:06.079
hit the i'm right here oh engage in auxiliary

00:02:04.640 --> 00:02:10.720
power now thank you roger don't have ignition

00:02:10.879 --> 00:02:18.800
i'll turn on the system so to kick things off

00:02:16.080 --> 00:02:23.200
we're going to be using a single one meter extension

00:02:20.480 --> 00:02:29.280
plus an additional 30 centimeter extension that's a total of

00:02:25.480 --> 00:02:31.840
130 centimeters this is the same as what

00:02:29.280 --> 00:02:38.239
we did for the wall pewter one more lower there you go

00:02:33.840 --> 00:02:41.680
stress test go so it's running perfectly

00:02:38.239 --> 00:02:44.480
as expected which means

00:02:41.680 --> 00:02:48.239
it's time to kick it up a notch baby let's take it to

00:02:45.879 --> 00:02:52.640
160 centimeters would you look at that still no dropped

00:02:50.400 --> 00:02:57.200
frames let's add more look at this

00:02:54.319 --> 00:03:02.560
it's ridiculous yeah

00:02:58.879 --> 00:03:02.560
down down down right there yep

00:03:02.840 --> 00:03:09.920
no 1.9 meters

00:03:07.040 --> 00:03:16.400
our pci express extensions are almost the height of darth vader

00:03:14.239 --> 00:03:20.319
okay so we're adding another 40 centimeters this time

00:03:18.400 --> 00:03:25.440
you can tell those thermaltake guys have a lot of confidence if they send us this

00:03:22.480 --> 00:03:29.920
much PCIe riser i am excited this was the best pci

00:03:28.000 --> 00:03:33.280
express riser technology we had around here so

00:03:31.200 --> 00:03:38.480
these aren't even shielded these you legitimately can't go very far

00:03:35.840 --> 00:03:42.080
with like i tried uh daisy chaining even two of these together and i had trouble

00:03:40.640 --> 00:03:46.720
with it so oh

00:03:44.239 --> 00:03:50.319
do we have failure okay let's try disconnect and reconnect

00:03:48.640 --> 00:03:54.319
just to make sure that we're being fair to it

00:03:51.680 --> 00:04:01.200
come on baby is the 650 ti PCIe gen 3 yet

00:03:59.840 --> 00:04:06.480
okay so maybe our load just isn't demanding

00:04:04.560 --> 00:04:12.319
enough maybe we need to bring out the big guns

00:04:09.439 --> 00:04:16.400
a titan xp okay so let's shut it down and let's try again so

00:04:14.879 --> 00:04:20.799
look at this okay so do you remember back when they

00:04:18.880 --> 00:04:27.280
launched this thing there was a bunch of press around the missing PCIe pins look check

00:04:24.240 --> 00:04:30.400
this out so these are power and then

00:04:27.280 --> 00:04:32.160
this is all data and NVIDIA swore up and

00:04:30.400 --> 00:04:36.720
down makes no difference makes no difference now we don't know

00:04:33.919 --> 00:04:43.840
if this is because it's gen 3 or if it's because it actually has all the pins but

00:04:40.160 --> 00:04:47.040
what we do know is that our 650 ti

00:04:43.840 --> 00:04:48.639
didn't go as far as our titan xp at the

00:04:47.040 --> 00:04:52.800
same resolution i mean arguably this is a bit of an edge

00:04:50.479 --> 00:04:57.840
case but um one can say the scenario is somewhat of

00:04:54.880 --> 00:05:00.320
a stretch i think we're gonna have to go even

00:04:59.040 --> 00:05:05.759
further straight to three meters

00:05:02.400 --> 00:05:07.840
should we do it yolo

00:05:05.759 --> 00:05:11.840
okay this is ridiculous i mean why would anyone need to no we need more table we

00:05:10.560 --> 00:05:16.560
need more table you have to hold the monitor now this is what happens

00:05:15.199 --> 00:05:20.000
in your relationship how many times do i have to say i'm not yelling at you i'm

00:05:18.320 --> 00:05:28.000
yelling with you okay be honest with me though are we expecting this to work no common

00:05:24.800 --> 00:05:30.000
it's on no artifacts or anything

00:05:28.000 --> 00:05:35.280
this is crazy how's it doing though 120 FPS same as

00:05:32.880 --> 00:05:38.400
before we're still getting the same frame rate

00:05:36.639 --> 00:05:42.240
no weird anomalies three meters

00:05:40.639 --> 00:05:46.960
that's like 10 feet for americans

00:05:45.280 --> 00:05:52.479
add 30 or add 60.

00:05:49.360 --> 00:05:54.160
do i really have to scream yolo okay

00:05:52.479 --> 00:05:58.240
monitor over on the other side and then just hold the graphics card here

00:05:56.400 --> 00:06:04.290
this is insane that's the last piece we have yeah 3.6

00:06:00.880 --> 00:06:06.880
okay no one come through this door

00:06:06.880 --> 00:06:14.479
no it's still working

00:06:12.000 --> 00:06:18.800
no way wait

00:06:16.240 --> 00:06:22.400
maybe that's all we got oh oh it's at postcode 40 now

00:06:20.479 --> 00:06:25.600
same as last time eh same as last time okay hold on let's shut it down no let's

00:06:24.240 --> 00:06:29.759
i'll do a quick reconnect of all the things okay hold on also keep in mind

00:06:27.600 --> 00:06:32.400
that these are not powered so perhaps it's not even signal loss it's just

00:06:31.120 --> 00:06:38.000
power loss oh you could be right

00:06:34.560 --> 00:06:38.000
three two one blast off

00:06:38.720 --> 00:06:44.120
no look at this

00:06:43.039 --> 00:06:49.520
look at this 3.6 meters

00:06:47.360 --> 00:06:52.639
you could literally have your graphics card

00:06:50.560 --> 00:06:59.440
in another room okay hold on i gotta run for mark though

00:06:55.360 --> 00:07:02.440
show me the 120 oh oh oh oh oh

00:06:59.440 --> 00:07:02.440
no

00:07:03.680 --> 00:07:10.880
no the FPS is going up though it's at 55 fp

00:07:08.639 --> 00:07:14.880
86 25 14

00:07:12.880 --> 00:07:18.639
30. no

00:07:17.759 --> 00:07:25.360
oh wait no it's so borderline

00:07:25.360 --> 00:07:31.360
oh it just teases me every time

00:07:29.039 --> 00:07:34.400
welcome to my personal life oh okay well i think we've reached the

00:07:33.280 --> 00:07:38.400
limit ultimately we failed when we tried to

00:07:36.720 --> 00:07:42.240
yolo too hard but i still consider this a success

00:07:41.120 --> 00:07:49.599
three meters of pci express extension

00:07:46.720 --> 00:07:53.080
and we managed to get it running at a an equivalent to having it right in the

00:07:51.680 --> 00:07:58.240
socket 120 FPS

00:07:56.080 --> 00:08:03.680
so thanks to thermaltake for providing all these PCIe risers and thanks to

00:08:01.280 --> 00:08:06.960
the uh slav for holding the graphics card how's that 85 degree GPU right

00:08:05.759 --> 00:08:11.360
there i stay holding my hand against the hot

00:08:08.800 --> 00:08:16.319

video oh it just turned off

00:09:16.880 --> 00:09:20.000
did it just hard reset

00:09:20.880 --> 00:09:28.560
or did it just hard off it's at a zero this thing's done

00:09:26.640 --> 00:09:31.760
