dats y... its not for noobies to play around... does your mobo have 2 pcie slot? get another card, put the problematic card in the 2nd slot, and use rbe and winflash to flash back default bios for ur 4850... and take this as a lesson

edit: must blame OC4/3 oso, u recommended him soft vmod

erm... by right, no

... but usually they close 1 eye, as long there's no burn mark on the card, they will still accept rma... otherwise customer not happy ma

I dun blame anybody bcoz its my own choice to play around

anyway, everyone's a noobie from start

I dun wanna b a noobie forever dats y i opted to try.....found out this winflash does hav some probs to work with Palit Sonic hd4850, other boards i dunno la, but from the infos i read, works well with most reference boards

FYI, my motherboard has no 2x PCIE or onboard, so I borrowed a PCI vga card from a Pentium classic.....re flash ori bios with ATIflash (dos), startup using USB stick go into DOS, flash it with command 'atiflash -p 0 newbios.bin'

i fixed the prob with zero cost and my sonic hd4850 now back to normal...

in case anybody needs help, PM me, i'll try my best to help

i see.... well, try this if u dun mind

1. overclock using ati overdrive
2. go to profile manager and save the profile
3. go to C:\Users\<username>\AppData\Local\ATI\ACE\Profiles if ure using vista, xp go to C:\Documents and Settings\<username>\AppData\Local\ATI\ACE\Profiles if not mistaken
4. open the .xml file using notepad

u should see something like this:

There, your card is not a reference version in the first place. That's the thing that caused all the problems
