i can do maximum on even prototype...but the main things is...my pc now easily crash...the heck..i dun mind if only the sound is too loud...but crashing my pc?hmm..

hye all..im new here..just bought this card bout a week..just wanna know the best catalyst version..rite now im using 9.5..thx

Ok i just bought sapphier 4850 GDDR4 yesterday..
Stock speed at 650/1100

With no voltage tweak the highest clock i got with 3dmark vantage BUT not stable when playing crysis :

720/1130


DEFAULT CLOCK





@720/1130 normal oc





Quite good eh? maybe it can go more with voltage tweak AND heatsink for ram coz THERES NO HS FOR RAM S@#$

It seem like i cant oc ram at all, stable clock for crysis just at 680/1100... >.<



Edited : New stable clock

Hi guys..

im a newcomer of this ATI world.. been an NV user since over 5 years ago lmao.

now im here as ATI card user. XD

looking forward for some good insight about ATI hardware.

Currently im using a revised version of Sappire HD 4850, Dual slot cooling with Hynix ram chips visible on the card lol.

i tried google my card over the net, cant seem to find it lol. So far managed to run games stable at 700/1150. anything higher will crash.

9.7 lo..

if u heading here:
http://en.wikipedia.org/wiki/Glitch
u should understand more on what it's meant..

for ur case.. u are pushing the card off the limit beyond it's spec..
bad results may happen..
