Steve...I'd like to preach a little bit of caution here. There are no set rules when using high V & VTT...some chips can take it, some die without warning rather quickly. IF your SS can hold 6 cores @ -35+ for this venture....I think that would be about max. So whatever speed you can get to maintain these temps. Forget about 6ghz, not going to happen. I think 5.2 would be about max....these b*ggers run hot and with this being such a long Benchmark..time will be against you as well. You just won't be cold enough to get really big clocks out of your chip. You would need to at least hit -90 for 5.5 etc. Sorry, just my opinion but better to be safe than sorry and I don't want to see you kill your chip.
