What happens if I increase the PCIE clock?

Hey all,

So running a blackops here, with a GTX285 OC2. With the AEGIS PANEL (brilliant piece of software) It shows my PCIE Clock at 100MHz and if i click on the overclocking tab, I can change it.

So if i was to increase it... Will i see any performance increase? Or will my poor already overclocked gfx card go *boom* :eek:

Leave it alone, if your card is running fine at the moment - do not touch the PCIE clock (a very fast and easy way to brick your card).

If you want to squeeze some extra speed out of your card - have a play with riva tuner or the AEGIS software you have. You can change the shader, core and memory clocks - just need to find a balance where it is cool and stable.

Adjusting the PCI-E will not brick the card :/

I've heard it can corrupt data on your hard drives though if you clock it too high...I usually just set mine to 105MHz .

Hummm... I spent £260 on this card... I'll leave it alone. Not worth the risk.

Cheers guys

Back before locked dividers when people over clocked the FSB the PCI and AGP bus would get raised as well. All that happened really would be devices on the agp and pci bus would start acting wierdly.

Don't let what he said stop you, it's not true. You cannot do anything to the card by overclocking the PCI-E...whether it will do anything for you other than increase scores a few pts in benchmarks is another matter

I was just going by advice that was passed on to me - basically "don't touch PCI-E bus, it won't help and bad things can happen", anyhoo -overclocking the memory, shaders and core will give you better results anyway.

Maybe this advice is a bit outdated -but I play it safe with my graphics cards.

Yep will be fine at 102-103 if you overclock with rivatuner it can help keep it stable. Kind of like upping the v on your cpu to keep it stable when overclocked.
