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 browse privately and securely with tunnelbear the simplevpn app start 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 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

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
