x800xt o/c speed possible?

Hi guys:

Just looking for some insight here. I was browsing threw eBay..and stumbled apon a system.

2gb ram(brand unknown)
Abit IS7-E2, P4 3.2 o/c'd @ 3.6 (s478) but what i would like to know, is it possible to o/c an x800xt to these speeds 450/750 (1500)? Seems rather high and i don't know what cooling is even used. My x850xt(bba) was able to reach 1260mem before getting any artifacts. Just wondering if that mem speed is actually possible on that card. Thanks!!

with good cooling id say so, even with just good air cooling if the memory happens to be samsung 1.6ns

I am sure with good cooling yes. But hell, there is alwaysa chance you might get a card that OCs 1 mhz on the memory before it artifacts.

i wouldnt count on it. the 1260 u got is already very high.
