Ok, so this is the newer sapphire 4850, with improved cooling, and it comes on a smaller pcb.
The problems i have are that i cant seem to overclock the card using the BIOS mods with RBE and winflash, ie, i edit the bios, flash it, check with gpu-z/CCC and it either makes no visible difference or the clocks appear to have changed but the card does not run any faster, i get standard scores in benchmarks, so its as if the card is ignoring the new clocks.
Secondly, i have found info on how to voltmod the original 4850 on the older pcb, but not for the new/improved 4850 pcb. The pictures of where to apply the pencil-mod are clearly for a different pcb and do not match my sapphire 4850.
If anyone can help me with overclocking this card i will be most grateful
as it is now i can get 685/1100 using ati overdrive, but im reading of people hitting 850-900 core speeds and i feel inadequate and slow ! hehe
gonna have to sell it if i cant overclock it properly.
cheers
