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

core clock can go high but not mem clock T_T... mem clock push too high with core clock = artifacts... tak puas giler 

mind telling us exactly how u tweak ur card with rbe?

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:

          <Property name="Want_2" value="1123" /> <--------- this is the core clock voltage that you should edit. 1123 refers to 1.123v, same goes to mem clock.... be reminded, it is recommended to keep it at 1.2v or below, since ure not doing pencil mod ...

do it at your own risk
