After the bios vmod you should be able to run it at 700/1000 at least.

What OS ? Clean install ?
Without clean install you wont notice it coz you are still using the 8.7's files  |

After uninstalling the 8.7, i use Driverheaven's Driver Cleaner Pro to clean the files. Then i restart the pc and install the 8.8 and it says that i dont have supported card. This issue are already discussed all over the net so i guess its not new anymore. Just to share with you guys..
The fact is that ati mislinked the driver..  |

Yes, I've increased the vGPU to 1.2v on the MSI biosbecoz for 1.2vgpu u can oc the core to 700mhz stable 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.  |
