So Ill include system specs in the end but heres the deal.
I have a quad core proc that I was playing around with overclocking. I've pushed this proc from 2.6 to 3.02 before and ran prime95 for 6 successful hours and ran with those settings for a while. Approximately three months later I decided I wanted to see if i could push the clock a little further by upping the voltage a little. During the previous process I had lowered the voltage until the system didn't boot then upped it enough to make it boot just to test power consumption with the new 3.02 clock. All ran fine with that voltage and I was fairly satisfied with the clock so never pushed any further. Well during the first overclocking I had realized that my motherboard didnt have an obvious multiplier. Those familiar with the evga 730a Board will understand what I'm referring to. This time around upon trying to change the clock I had forgotten what specific setting needed to be toyed with to change the clock on the cpu. I decided to get a little more familiar with my bios did some research toyed with the voltages a little bit but nothing that could do any damage. Long story short I figured out How to change the clock via some CPUFID hexi decimal setting. At this point I had reset bios, and the procs default 2.6 so I pushed it to 3.0 just to get familiar with the hexi system. Upon boot, I realized during the running of prime that it was testing as If I've only got a single core proc. And in Task mgr it reads it as a single core. I checked system settings, its reading proc just fine. I checked all drivers everything looks solid. Here is a list of things that I've done to diag the problem, unfortunately with no luck
Reinstalled ALL mobo drivers
Reset, pulled battery, and even flashed bios
Rolled back to sp1 in vista
The few things I havnt tried include reinstalling the o.s. and reseating the proc.
Here are the system specs
Evga 730a mobo Newest bios update
amd phenom 9950 quad stock 2.6 now at 3.0
8 gigs ddr2 ram
gtx260
raid stripe 7400 rpm 500g sata hdd
vista 64x sp1 (rolled back because this was a recent change that could have contributed, unfortunately it was a no go)
Im afraid its possible that during the over clock and voltage changes I burned my other three physical cores. But am not recieving any cpu errors or crashes of any kind. I'm wondering If its possible the mobo is undervolting my proc at default bios and only able to run 1 of the 4 cores. Or even better wondering if there is a setting of some kind in the 730a bios that allows for core control..
Any Ideas anyone?
