eye2eyespy Posted June 16, 2022 Share Posted June 16, 2022 Silly Question Maybe... How can I find out if my PCIE lanes which is 16 is running a full capacity? I have a TRX40 10G (3960X CPU) with 4 (16) PCIE lanes (support x16/x8/x16/x8 mode) because of my case and PSU I have to place the GPU on the last lane away from the CPU. Will this hurt performance. The motherboard says that all lanes run at 16??? Not really sure? Link to comment Share on other sites More sharing options...

eye2eyespy Posted June 16, 2022 Author Share Posted June 16, 2022 That's what I thought, definitely the most help so far on the web. Other forums have been condescending and mean. Just a question, how significant is the loss of performance running out side of the 1st lane? Many thanks Link to comment Share on other sites More sharing options...
Supervisor fabiosun Posted June 16, 2022 Supervisor Share Posted June 16, 2022 Not so much it is so difficult in normal usage to have all GPU power saturated...maybe in some particles and physicians high simulation softwares..but if you do video editing or rendering is not so important the loss but.....I would change my cabinet if I were as you are now 🙂 🙂 Link to comment Share on other sites More sharing options...
eye2eyespy Posted June 16, 2022 Author Share Posted June 16, 2022 Ok, thank you very much, I will. Any other advise/tops for getting the most out of my GPU (optimizing)? Link to comment Share on other sites More sharing options...
Supervisor fabiosun Posted June 17, 2022 Supervisor Share Posted June 17, 2022 No it doesn't need any tips to be optimised It seen by default by OSX drivers, we can't do anything more to improve performance You can use web or a SSDT to have GFX0 shown in your IOREG instead of display0..like a real Mac!

eye2eyespy Posted June 18, 2022 Author Share Posted June 18, 2022 Lol take a look a this guy. He told me to get a different case or gpu. https://forums.tomshardware.com/threads/xfx-6800-xt-pcie-lanes.3766524/ Appreciate your help. Link to comment Share on other sites More sharing options...

Supervisor fabiosun Posted June 18, 2022 Supervisor Share Posted June 18, 2022 It is a bit different your motherboard slot for GPU are all PCIE 4.0 and your cpu could feed it different story are 16x,8x,4x and gpu position in many task performance difference is not so much and you can’t see any speed If we talk to have a optimal condition gpu must be inserted in one of the slot @16x and in my opinion with a more comfortable cabinet you solve this i would not change your gpu , it is one of the most powerful and beautiful in the gpu scene… I would change only with is greater sister (6900 xt) 😂 Link to comment Share on other sites More sharing options...
Traace Posted August 24, 2022 Share Posted August 24, 2022 AFAIK it is not just the PCIe Speed that counts. Slots closer to the CPU should have lower latency than slots further away. But maybe it is neglectable 🙂 Link to comment Share on other sites More sharing options...
