okay so when we were building our wall pewter wall computer well pewter get it
anyway one of the challenges was having the graphics card on the opposite side
of the frame versus the motherboard i mean this thing was so far away that
there wasn't a single pci express riser
cable on the market that was able to reach
so the solution use more pci express risers we actually
ended up with a one meter thermaltake
premium extender chained to a 30 centimeter one and we
pulled it off with no performance degradation whatsoever the system worked
perfectly fine which got us thinking
just how far can you go
before things go haywire
stick around while we uh snake our way
to the conclusion

okay so to kick off the experiment we rigged up our standard GPU bench machine
so it's a known good machine our pci express signal integrity should be about
as good as it can get then we needed an extra piece so we also hooked up a
separate power supply for our gtx 650 ti
graphics card this is so that we don't actually run into power cable length
limitations if the experiment goes completely off the hook
also having an excuse to call out to ivan like he's far away is a
is a bonus so uh hit the power switch chekov
so i did catch that can you repeat
hit the i'm right here oh engage in auxiliary
power now thank you roger don't have ignition
i'll turn on the system so to kick things off
we're going to be using a single one meter extension
plus an additional 30 centimeter extension that's a total of
130 centimeters this is the same as what
we did for the wall pewter one more lower there you go
stress test go so it's running perfectly
as expected which means
it's time to kick it up a notch baby let's take it to
160 centimeters would you look at that still no dropped
frames let's add more look at this
it's ridiculous yeah
down down down right there yep
no 1.9 meters
our pci express extensions are almost the height of darth vader
okay so we're adding another 40 centimeters this time
you can tell those thermaltake guys have a lot of confidence if they send us this
much PCIe riser i am excited this was the best pci
express riser technology we had around here so
these aren't even shielded these you legitimately can't go very far
with like i tried uh daisy chaining even two of these together and i had trouble
with it so oh
do we have failure okay let's try disconnect and reconnect
just to make sure that we're being fair to it
come on baby is the 650 ti PCIe gen 3 yet
okay so maybe our load just isn't demanding
enough maybe we need to bring out the big guns
a titan xp okay so let's shut it down and let's try again so
look at this okay so do you remember back when they
launched this thing there was a bunch of press around the missing PCIe pins look check
this out so these are power and then
this is all data and NVIDIA swore up and
down makes no difference makes no difference now we don't know
if this is because it's gen 3 or if it's because it actually has all the pins but
what we do know is that our 650 ti
didn't go as far as our titan xp at the
same resolution i mean arguably this is a bit of an edge
case but um one can say the scenario is somewhat of
a stretch i think we're gonna have to go even
further straight to three meters
should we do it yolo
okay this is ridiculous i mean why would anyone need to no we need more table we
need more table you have to hold the monitor now this is what happens
in your relationship how many times do i have to say i'm not yelling at you i'm
yelling with you okay be honest with me though are we expecting this to work no common
it's on no artifacts or anything
this is crazy how's it doing though 120 FPS same as
before we're still getting the same frame rate
no weird anomalies three meters
that's like 10 feet for americans
add 30 or add 60.
do i really have to scream yolo okay
monitor over on the other side and then just hold the graphics card here
this is insane that's the last piece we have yeah 3.6
okay no one come through this door
no it's still working
no way wait
maybe that's all we got oh oh it's at postcode 40 now
same as last time eh same as last time okay hold on let's shut it down no let's
i'll do a quick reconnect of all the things okay hold on also keep in mind
that these are not powered so perhaps it's not even signal loss it's just
power loss oh you could be right
three two one blast off
no look at this
look at this 3.6 meters
you could literally have your graphics card
in another room okay hold on i gotta run for mark though
show me the 120 oh oh oh oh oh
no
no the FPS is going up though it's at 55 fp
86 25 14
30. no
oh wait no it's so borderline
oh it just teases me every time
welcome to my personal life oh okay well i think we've reached the
limit ultimately we failed when we tried to
yolo too hard but i still consider this a success
three meters of pci express extension
and we managed to get it running at a an equivalent to having it right in the
socket 120 FPS
so thanks to thermaltake for providing all these PCIe risers and thanks to
the uh slav for holding the graphics card how's that 85 degree GPU right
there i stay holding my hand against the hot
backside today's video is brought to you by lg's
share the art promotion featuring their ultra lightweight lg gram laptop lg
worked with a coffee artist who came up with three pieces of artwork inspired by
the gram you can check them out at the link in the video description what
you're going to want to do is share the post on your social channels and write
the post's url on the event page for a chance to win a prize you could win an
lg monitor an amazon gift card or one of
14 lg grams for participating and even
if you don't win you can get another chance by visiting the behind the scenes
youtube link also in the description and commenting on your favorite feature of
the gram the weight it's really cool oh and battery life
