Sudden boner last night....:p
Too early to tell (only 2 lts of LN2 spent on that )but chip seems to have much more in it...
OS was a bitch and wouldn't let me play with BCLK, only with multi's so the next step was at 6690 wich led to a 1M fail in the 10th loop....

Next test tonight with proper OS and more time.
