Does it make much if any of a diff, I run mine stock 100 on my Ultra-D mobo and system specs in my siggy. Well it help any if i go up a little or cause probs.

Do not touch the PCIE Freq. unless you want a dead card

Raising the PCI-e frequency will not kill your card :rolleyes:

It can however corrupt data on SATA drives. As a general rule, upto 120 MHz should be OK, but its best to leave it at default 100 MHz as PCI-e locks are effective these days. (Unlike the intel i915 days...ah the memories :D )

does it affect the performance much?

I've heard that upping PCI-E to at least 118Mhz is required for stability on 7900GTX's over 720 core.

PCIe frequency definately has something to do with GFX oc'ability. For example my X800GTO R423 core does only ~640MHz @ PCIe 100MHz. Give it 120MHz and it goes atleast up to 666MHz

I have ran mine at 105 for ages now with zero issues on all my ATI cards.

I've run up to 120mhz, never noticed any increase in OC'ability but DID notice a 300+ point increase in 05, at high speeds (750/900).

That came at around 105mhz though, between that and 120, little increase.

I run mine at 105MHz just because. I notice no difference with the frequency higher. It's kind of like filling your car's tires with 34PSI instead of 32PSI, in my mind.
