just installed AMD Bulldozer X8 FX-8150 but sytem not seeing all memy

put my old cpu in and everything is working fine!! so can it be a bad cpu that will not let 2 of the ram slots work properly?

Well with that exercise then it seems that it could be. Check the pins very carefully for missing or bent pins. I would request an RMA to AMD for complete evaluation.

Yes, the memory controller (MC) is in the CPU.

my old cpu amd athalon x4 630 is 95watts and the fx8150 is 125watt, would that have anything to do with the power supply not sending enough juice?

On the new Asus mobo are you running the latest version of the required bios for the FX chip? Double check and if not then update carefully and retry installing the FX. Sorry but you may still have to send the chip in to AMD....drag !

yes newest bios

No as upgrading to the new sabertooth solved that issue.

Fingers crossed !
