Bad vid card = instability?

[Kil4Thril]

I had hellacious problems getting an overclock to be lengthy-Prime stable. I blamed my memory controller, mostly. Yesterday, my X850XT died completely, one of the RAM chips literally fell into my hand when I was looking it over. On 3-4 occasions, I would come into my office, always before work, and find the machine locked up with either no screen, or a bunch of colorful vertical lines. I now know it was the card.

Now, the question: could this card's ineptitude have caused me to not be able to OC at all, due to stability? I know I could always run my RAM at super high FSB's, but I could never get totally stable. BTW, I Primed for 11.75 hrs last night at stock using this POS Radeon 7200PCI

Yeah, I remember seeing those lines when I had an 8500 from Radeon, it wasn't the card believe it or not. Probably the motherboard then man?

Its a shame to hear that your memory module fell off, its a good card too.

Oh, I'm positive the card was borked, I was just wondering if the bad card prevented stable overclocking, or if that was even possible. I won't be trying again until I get my new stuff.

bad card can cause stability issues even at stock speeds...
