I just bought this mobo, along with some other new parts, in hopes of getting at least some OC done. Everything I've tried thus far fails.

I've gotten it to post 1280MHz QDR but anything above that is not posting. Everything but the stock 1066MHz fails to load Windows, it will just restart during loading.

If I set memory to 1066MHz manually it fails to load Windows. Upping voltage doesn't help and at 2.2V to mem it fails to post.

Should expect anything better than stock 1066MHz with stock NB and SB cooling?

My rig is:
C2Q6600 G0
2x 1GB A-Data PC-8500 Extreme Edition
2x nVIDIA 8800 GTS 512MB (G92) in SLI mode

Cooling:
4x 12cm case fans, two in takes and two outputs.
