hi i got an x2 4800,i have never had a single problem with my ultra-d and have swaped from a 3200 to an opty 146 to a x2 4800 and have been happy with it.my wife has my old 146 and so i got a 165 for her,but, being an oc'er i wanted to see what i could get out of it before i put in her machine.now i get problems,first of it wont boot,so i do the clear cmos and minimal boot and finaly get it to boot in single channel mode.so it wont boot in dual channel at all.i put my 4800 back in and it wont boot.so i clear cmos and everything else after 3 hours i get it back.it has been doing 2.8ghz for months on end ,prime stable and f@h.i get it back and at stock settings i start f@h and it crashes and reboots,but no boot.so i clear cmos finaly get it back in dual channel again and im at stock.

what is going on with me mobo......
