Ok, so I have been playing with my XFX HD6870's and unfortunately I cannot adjust the voltage with MSI AB nor can I go above 1000Mhz on the GPU and 1250 on the memory. The best I have been able to do is 1000Mhz on the GPU and 1223Mhz on the memory before I start getting stuttering during a vantage run. I am assuming this is at stock voltages since I cannot adjust that. However, I have ran into another issue besides the ones mentioned above. When I do a full Vantage run (not just GPU tests) Vantage will error out with some strange code that I haven't been able to find via Google, I will have to post it later, but it only happens on the CPU tests. I have tested my overclock via OCCT Linpack and it passed two different times. I have the latest patch of Vantage, so if anyone has any ideas any help would be great. Also, if I do the "EnableUnofficialOverclocking" mod to MSI AB, will that enable voltage adjustments also? I remember on my HD5870 I had to flash it to an Asus bios to achieve this, but it would be nice to not too have to do this.
By the way, this was my 3DMark06 run I did at 1000/1223:

Score was 27860
So I can do full runs in 3DMark06, just not Vantage.
Here is my GPU only test in Vantage at the same test:

GPU score was 30530.
