My first post here, although I've been around on ocau a long time. Made the switch from AMD to Intel c2duo and so far enjoying it.

Gigabyte DS3 - F11a bios
e6320 - 3.6ghz (515 x 7 ) @ 1.5v
2GB Kingston DDR800 @ 2.2v
8800gts 640mb

Been a fairly painless process to get a great overclock on this chip, thermalright ultra 120 extreme probably helps.

I can't seem to squeeze anymore out of the FSB for this board. MCH is at +0.3v with Noctura nb heatsink which is warm to touch but not burn finger temp to touch like the stock nb heatsink. 515 FSB is rock solid, been Orthos's for days and memtest'd. I can push it to 535 and benchmark but it will usually become unstable after ~30minutes.

If I set the multiplier to 6x I still cannot get more FSB so I feel it's a limitation of the board. Looking around seems 510-520 is top for these boards.

Assuming the ram can handle it, I am going to attempt the MCH +volt mod from vr-systems. Anyone here done this sucessfully? Temps from coretemp never rise over ~48 so I have a little headroom as far as core voltage goes if I need it. http://sg.vr-zone.com/print.php?i=3870

p.s I too got that noise from the components on the motherboard, I believe it is just the cheapness of the components. A quick spray with WD40 and my noise almost went away entirely have to strain to hear it now.
