Hello I have a question. I have a pretty crappy G31M motherboard so in order to OC I have to OC my PCI-e frequency as well. I would have to go as far as 121 to keep the clock that I need (actually have to set the frequency to AUTO but according to Setfsb 121 is my frequency and I'm fairly certain its correct). Ofc when I try to lock it at 100 can't boot.
Weird thing is even if I manually set it to the 121 value it won't boot, I have to keep it at AUTO for some reason, this is kinda odd but nothing I can do about this.
Now I heard a lot of horror stories about computers going up in flames at 105 (exaggerating ofc), but a lot of these stories come from a third person as in "I've HEARD people frying their stuff" and very rarely somebody had their own experience.
Also some people report that they can't even boot at higher frequencies, but after lowering them again everything is fine.
On the other hand I've also heard people going for months on 120 pcie without any problems.
So my question is, does anybody have PERSONAL experience with overclocking the pcie bus this far and something going terribly wrong?
And I'm thankful to all the people saying "Don't mess with pcie, just lower the OC", I'm well aware that it iss kinda dangerous, I would just like to know how much are we are talking about.
pci-e frequency is for the gfx card and totally separate from the cpu overclocking features on every motherboard.
it sounds to me like you have mixed up your fsb frequencies with the pci-e bus frequencies. if this is so its likely you have damaged your gfx card because you have mistakenly overclocked the pci-e rather than the front side bus and cpu. this would result in a no boot.
reset your bios and try again. but make sure you use the advanced cpu features which will be in a separate menu to the pci-e if your lucky...
