Need some help about OC

[Laktor]

Hello A while ago I overclocked my processor and everything went fine (locked pci @ 33.33mhz and pci-e @100). After a while I started having problems with my video card, computer crashing, screen going dark, artifacts etc. I reset my overclock back to normal but I kept having these problems. I nocticed my video card fan wasen't running all that good I had lots of dust in there so I cleaned it out and got my temp down for 80c -> 60c or so and the problems dissapeared. I never got back up to 80c so I don't know if i still would get those craches @ that temp. Anyway I tried to overclock again locking pci-e @ 100mhz and directly after the overclock I tried to play again this time the problems got even worse I got lots of artifacts at even the lowest temps I think above 48c or so.

That got me a bit puzzled since I locked the pcie @ 100mhz and everything and it seemed the card got even worse after oc'ing the processor. Anyway could it be the card was already faulty as it was or something and the oc made it even worse, The reason im asking this is becuase I replaced the old card and I wanna try oc'ing again but im not sure becuase I dont want the same thing to happen again. Is it possible that the motherboard still raises the pci-e frequency even though its locked? My motherboard is a asus p5b and processor e6400.

Any insight would be helpfull thanks.

If the lock isn't working. I've heard that some motherboards don't actually enforce the setting.

In that case is there any way to see if its not actually locked, like if I would lock it @ 100mhz then raise the fsb abit and see if the mhz on pci-e would follow?


Another guy had a similar problem he locked his pci-e @ 100mhz but as soon as he would overclock the processor the video card would start acting strange giving artifacts and bluescreens, the only difference is that when he would go back to stock speeds his video card would start working normal again, my old one would keep acting strange @ processor stock speeds.

If the card fan wans't working well, and it was running hella hot (80c=176f), then the video card is probably fried. It would depend on the card and its tolerances.
