DIMM slot is working again!!!

I pulled the CMOS battery out, closed the clear Cmos jumper, and left it sitting for 10 minutes, fitted the battery back, removed the jumper, and turned on my rig, and all my RAM was detected...

However, I then loaded optimzed defaults, and enabled XMP profile for my Dominator RAM, and when I saved and exited the BIOS I looked at the POST screen and only 2 sticks were being picked up!!

I removed the Dominators, and put my XMS3 set in, and it was working again...

This rig is causing me so much stress, I am sick of it, I can't use it for its intended purpose, and that is driving me mad...

All I can hope for is that the new mobo will sort all my problems, and then I can return my current one for a replacement...
