I've been looking everywhere on different forums...seems that most X1800XLs are OCing quite well. However, some fail to do so.:censored:
I have a BBATI card on water with ram sinks (using ATI Tool beta 11):
Core = 621Mhz
Mem = 666Mhz
vCore = 1.150v (1.175 locks up randomly without artifacts, higher results in immediate lockup)
vMem = 2.1v
vMemIO = 2.0v
I am speculating that there may be something in the ATI BIOS that says anything over 10% higher on vCore (1.175v would be ~12% increase...but it's possible that the voltage fluctuates at just under that and eventually causes a lockup)...halt all video operations, but I cannot confirm this as of yet. I have reports of 2 other BBATI cards doing the same.
Can I have everyone input their OC results maximum stable (not just bench stable), the maker of the card, and the cooling setup. This is for X1800XL only. I have not heard of anything funky with the XT cards unless they arrive with bad memory.
I will be creating an excel spread sheet with the results and hopefully come to a conclusion to help my self and others with difficulty OCing these cards.
Thanks everyone!:D
