PCI-E v3 help please

[ukn69]

So after testing my OC on my Asus Titan, my fps is below the average of what everyone is getting on Valley benchmarks. GPU-Z says its running in PCI-E v2, though in my bios, its set for gen 3.
Anyone have the same mobo that knows a fix or know why its not running 3.0?



Running on:
Asus Rampage IV Gene
i7 3820 @ 4.6 (yes 3820 supports pci-e v3)
16 HyperX Kingston
Asus GTX Titan

Right click the file and select run as administrator. After reboot you should be on Gen 3 (your BIOS/UEFI has to have it enabled as well). I don't think it'll improve your benchmark results much though.

Hmm strange I thought the 690 and the Titan would run gen 3 without this but...there is a manual method too...first post this thread:

As cx-ray said check your BIOS is gen 3 enabled...

But it shouldn't make that much difference.

Carefully check the temperatures of your CPU and the VRM when running benchmarks...if you are not actively cooling the VRM for example you might be throttled and getting lower scores because of this..

Thanks for the reply guys. Yea from what ive been told, only x79 boards (mainly Asus) need the manual method. Reads Gen 3 now, shame the performance isnt effected, kinda defeats the purpose of it in the first place. I found out 69-73 average fps in Vally (max settings) is normal, people were "cheating" to obtain 79+ average i was told. Well thats a differ story, thanks for the replies

It's not mainly Asus, it's all X79 boards that need it. SB-E is still not certified no matter what nvidia releases it won't fix the CPU issue. So until IB-E, it's enable manually and see if it works.

GEN3, may actually make some a very small difference on the Titan. Did you run a 3dmark 11 with both settings?
