6.1 benching, run order and 121 800

EDIT :




No cold bug until -165, so too much cold for my poor insulation. Will be back again tomorrow But SLI is working quite good, the 1k missing is probably due to the single channel memory.

Yeah it's great fun, I'm having issues with the board not loading windows a second time after enabling SLi with dual channel ram - with single channel it works fine. Very strange issue. If anyone has experienced this and knows a fix please let me know.
