So today I discovered a rather shocking realization. My graphics card was apparently running at x8 instead of x16 BUS setting. I found this out when I glanced over the AMD control center. So I opened up GPU-Z and it confirmed that it was only running at x8.

So what I did was I took a trip down town to the BIOS and disabled something called I/O levelup, which had the following options USB3, SATA6, Disabled so I choose disabled. The GPU-Z and control center now displays the following setting of x16.

What I want to know is why was it set to x8? Is it cause my mobo doesn't have enough bandwidth to go around? And also is there anything else I should change/look for? And also what are your thoughts?

Motherboard: ASUS P7P55D-E LX (LGA1156)
Graphics Card: Club 3D AMD Radeon HD 6870 1GB

I'd benchmark the two different settings to see if it made a real difference. A lot of bus/transfer technologies seldom get saturated. They are normally replaced before that.

hmmm good point, I will run benchmarks tomorrow, going to cod bo now and see if it's any better. :)
 
LGA1156 - therein lies the answer. It scavanges PCIe lanes to feed USB/SATA3
 
This thread is useless if you have not bench marked it nom nom. Apart from it being 8 and 16 i doubt you will see any difference.

This is the answer. It's onlt socket 1366 that has enough lanes for everything. Or 890GX like you should have gotten in the first place :P
