*** Official Radeon HD5800 Series Overclocking Thread ***

Yes, it's basically being confirmed by Dave, "We scale the voltage". Aka, "we bin the chips and assign 3D voltages accordingly". It's similar to VIDs - not like every Q6600 clocks the same on the same Vcore. Really, you want a 5870 that runs VERY cool while clocking upwards of 950-1000mhz on a stock 3D voltage of ~1.12-1.13v. You might have to sample 20 or 30 different boards until you find one like that! :p Heres to the guys that have a 3D volt of 1.125 in bios and can go above 950mhz with it.

900 / 1300

Dual core cpu without gpu Physx.. don't expect much from 3DV.
Nice GPU score though. :p

Got my 5850.
His brand.
...

At 0xAA overclocked 850 on core added the following increases fps (58 to 71 min fps) (115 to 127fps average) 231 to 254 max fps)

Flopper, what volts for 850mhz on your HIS 5850?
