have u checked the bios using rbe 1st before u flash??
becoz for 1.2vgpu u can oc the core to 700mhz stable

Yes, I've increased the vGPU to 1.2v on the MSI bios
670/993, stock vGPU & 1.2v - no crashes in 3DMark06
675/993, 680/993, 670/1000, 680/1000, stock vGPU & 1.2v - crashes in "dragon" test
I think it's due heat issue using stock cooler or PSU draw not enuf juice. sweat.gif

Increase the clock info 03-09, from 700Mhz to higher frequency e.g. 750Mhz.
Do the same for RAM. If necessary, increase the voltage to higher e.g. 1.2V.
Save BIOS, flash the BIOS with WinFlash from TechPowerUp, reboot pc & done.
