very nice tweaking indeed mate
you are on the wrong drivers though
you CH is terrible...you've lost 2000 points on it

interesting about your bugged CPU issues....my bench session consisted of me having to warm up my CPU to -76C from -120 every time i crashed or restarted my rig but it kept going until it started going a bit funny near the end which is when i pulled the plug

try insulating the whole area with plastic spray....should help a bit
