Confirmed that VBE7 does work with 280x cards. Flashed half a dozen Gigabyte 280xs this week, and they're all hashing @ 725KH/s @ 1.019V. Dropped consumption for a 5 GPU rig frim 1450W to 1250W, and lower temps as well. Test on one going lower and lower, and then flashing the others only took me ~5-10 minutes per card.

Hey bro is your 1.019 the VBE7 setting or what GPUZ reports?

I'm using Linux, so I can't tell you what GPUz reports. I do know that the 1.019V is what VBE7 reports, and then after the flash CGMiner reports the same value. Also, power consumption dropped by ~200W for the 5 GPU rig, and temps went down a good bit as well, so I'm pretty confident that it worked. Wink
