Question AIW x800xt mod-able?

[richard8794]

well this question might sound silly...
but I think I heard some kind of rumor that AIW x800xt is actually using R480 core.

I know AIW x850xt doesn't exist...but does this mean (if they indeed use 480core) can it be overclocked to x850xt PE speed?

thanks...

doubtfully, but it could be o/c to x800xt pe wich is almost close to x850xt pe difference is the x850 series use slightly smaller architecture i tthink .90mm or .60 but if u o/c to pe speed u better have a better fan or cooling especially since the tv turner add slight more heat, x850 line smaller architecture has a bit more transistors n diffuses heat slightly better.

According to Rojakpot's graphic card comparison guide, the AIW X800XT is R420. R420 and R480 are both on 130 nm process and have the same number of transistors according to that same guide. As in every other o/c scenario, you have to test to find out how far you can go. In any event, there shouldn't be a huge performance difference.

R420, R423, and R480 are all 130nm low-K. R430 is 110nm, R520 is 90nm.

Thanks for the alert DougLite, I've corrected my earlier post. I don't know what I was thinking when I wrote it - I've owned 3 R420/480 cards and should know better. Note that your list shows R430 twice, as both 110 and 130nm - it's the former.

the r480 uses a better process on the core, or is supposed to, so it can allow the huge 20mhz stock clock over the r420

either way the differences shouldn't be huge, the XT's go to XT PE pretty easy, hell my x800pro went to x800XTPE easy too, i think you might have a problem with OC'ing the ram to whats on hte XTPE

When I said R430 the first time, I meant R423. R420 and R423 are essentially the same thing, except one is native AGP and the other is native PCI-E. I'm wanting to say 420 is the AGP part.
