ATI 3850/3870 Voltmod thread

[Misko78]

After posting i found out on some Russian site that this Gainward is identical to Palit, so i force-flashed 3870 DDR3 bios into both of my Gainwards and they work on 780/950 setting . Overdrive max is now changed to 830/1000, not quite what i want but i'm much more satisfied then before.

With little help from monteboy i found feedback pin for BS-9M as well as VMOD points.

Unfortunately my Gainward died last night. Vmod and vmem were successful as i had it going at ~930@1,44V for core and ~1070@2,05V for memory. I was benching it for more than three hours without any problem. It was cooled with VF900 and with heatsinks on RAM and fets. Core temperature was around 85°C while doing 3dmark05 and 3dmark06. power fets where very warm but not hot at all. After, what i thought was a successful overclock, while i was playing with fan controller in RT i got thin black stripes on gray screen. I turned off computer immediately. When i turned it on card was completely dead. RIP
