question about PCI-E speeds!

post #1 of 6
Thread Starter 
i hope this is the right section.


anyways i was wunderin how great are the chances of messing up your video card/mobo if you turn up your PCI-E speed from 100mhz to oh lets say 105 or 110?

also i have my video card OC'ed so if i turn my PCI-E up to 105mhz should i lower my video card OC a little?

thnx 4 the help in advance!

You can take your PCIE freq. all the way up to 120mhz safely, however I tend to stick with 105-110 myself.

And don't worry about downclocking your card, my "detect optimal frequencies" actually went higher after setting up my PCIE frequency, so you're ok there.

I have no proof of the safe speeds, but I know that I had the same question before and asked around and got the same answer. Plus, I have personally pushed my PCIE frequency to 120mhz just to see if I got a boost in perfomance...nothing substantial though. It's much less from 110 to 120 than it is 100 to 110.

I don't think increasing your PCIe slot speed will do anything except heat up your card more and increase risk of damaging it.

Upping your PCI-E speeds won't increase the card's performance. I have heard on the forums that there are some stability benefits, but nothing to risk your card over. Current GPU's don't take full advantage of the PCI-E bus bandwidth (which is why the next PCI-E standard is supposed to deal with power rather than bandwidth), so upping the frequency won't do much for you.
