Can PCI-E Overvoltage do my card any harm?

post #1 of 7
Thread Starter 
Hi all,

I got an XFX 8800GTX last week, and started overclocking right away.
Unfortunately it wouldn't go any further than 621/1458/2016 without crashing my system, this even showing some artifacts in ATiTool after less than 2 minutes (in games perfectly stable however..)

But a few days back I heard from a friend who had upped his PCI-E voltage that he could get 10Mhz core/shader/memory stable than without.
So I did the same, also upping the PCI-E frequency to 105Mhz.

I've let ATiTool run for over 50 mins without any error whatsoever, so it really helps. I just want to know if this is safe for my card to do, I don't want to kill it or anything.. couldn't find much about it on the internet as well.

Thanks in advance

PCI-E voltage can harm any PCI-E device if its increased too much for long periods, same thing as juicing 1.65v through a 65nm CPU.

I forgot to say it was only 0,1 volt. Also, temps don't really seem to go up much as well.

your good up to about 110 - 115mhz .. i think its a myth upping the pci-e for better GPU clocks

though saying that mine is set @ 110mhz 24/7 & this is my best OC .....

742/1860/2000

pretty good for a GT with no volt mod ....so it might of helped.

but yes too much on the pci bus will damage H/W

My GTS has been running at 110mhz for two years now and it's still going strong
post #6 of 7
110-115 max is what they say is OK

i tried 110-115 and didnt get any dif results...

so

i tried 125 and ended up with a burnt peice of plastic, it literally burnt one of the rear mem modules....


same with pci-e overvoltage via bios, it never helped my OC any....

Well, to me it seems it does.. the artifacting has gone away.

Still, will +0,1V be dangerous or not?
