How many PCIe Extensions is TOO MANY??

2017-08-31
okay so when we were building our wall pewter wall computer wall Peter 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 war PCI Express risers we actually ended up with a one meter thermal take premium extender chained to a 30 centimeter one and we pulled it off with no performance degradation whatsoever the system works 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 Brow's privately and securely with tunnel bear the simple VPN app starts your seven day free trial at the link in the video description 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 eivin like he's far away is a bonus so i hit the power switch check off so I did cache that can you repeat hit this I'm right here oh engaged in exhilarate hour now thank you Roger don't have recognition I'll turn on the system so to kick things off we're gonna be using a single one meter extension plus an additional 30 centimeter extension that's a total of a hundred and thirty centimeters this is the same as what we did for the wall puter one more lower there you go stress us 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 a hundred and sixty centimeters would you look at that still no dropped frames let's add more look at this ridiculous yeah down down down right there yep Oh 1.9 meters our PCI Express extensions are almost the height of Darth Vader okay so we're adding another forty centimeters this time you can tell those thermal tape guys have a lot of confidence if they sent us this much pci you 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 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 gen3 yep okay so maybe our load just isn't demanding enough maybe we need to bring out the big guns a Titan XP ok so let's shut it down and let's try again so look at this ok 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 no one can say this scenario is some little friend stretch I think we're gonna have to go even further straight to 3 meters should we do it Yolo okay this is ridiculous I mean why would anyone need to know we need more table we need more table you have to hold the monitor now this is what happens done the other thing even out there in the relationship how many times I have to say it not yelling at you I'm yelling with you okay be honest with me though are we expecting this to work no comment 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 three point six 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 same as last time okay hold on let's shut it down though 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 is 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 fur mark though show me the 120s Oh No Oh no-ho-ho the FPS is going up though it's at 55 after 86 25 14 oh no it's so borderline oh just chases me every time welcome to that 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 and equivalent to having it right in the socket 120 FPS so thanks to Thermaltake for providing all these PCIe risers and thanks to the slab for holding the graphics card how's that 85 degree GPU right there I stay holding my hand against a HUD backside today's video is brought to you by LG's share the art promotion featuring their ultra lightweight LG gram laptop LG works with a coffee artist who came up with three pieces of artwork inspired by the Graham you can check them out at the
