ok here goes.

we installed an x2 4600 socket939 into my brothers
msi k8neo4 sli mobo. It previously had a 3500clawhammer.
after the cpu swap it booted up fine no windows reinstall or nothing.

windows and cpu-z only shows one core.

have tried bios update,reinstall of widows,amd dualcore optimizer.
and just about everything i can think of.

any ideas.

i can post pics and more info if needed.


edit; also ran a few multicore benchmarks which resulted in
only one core running.

thanks.

Try the link I posted above, the optomizer is a different download. You need the driver.

Did you check to your bios version? If you don't have an updated bios, it won't see both "cpu's". That sounds like your problem.

There's your issue right there. All 939 boads support x2, but only the newer bioses show the cpu as dualcore. A simple flash will do the trick

Have you tried the cpu in another motherboard, because if the bios is updated it means one of two things, either your cpu is bad, or you mobo is bad (which I'm guessing since you have also tried reinstall of windows)

Just wondering, how'd you find the time to post 5k reviews in only a few months?

Thats a good point, how did you post 5K+ reviews in such short time?
Or is it just a system error?

Anyway, during the initial post screen when starting up your PC, can you see if your BIOS detects it as a dualie? (eg. At the initial boot screen just above my memory capacity / cas latencies, my DFI board will say it has a 4200 X2, 2 CPUs)

Windows as in the Hardware installed section or the Control+ALT+DEL method??

Regardless of what CPU-Z says, press Control+ALT+DEL and in CPU usage ~ do you see two CPU cores being monitored??

I guess since you tried just about everything, and I'm guessing that the control alt dlt won't work considering that cpu-z registers it as single core, but just wondering, does cpu-z atleast register the processor as an x2 4600, because if it doesn't, then it is a mis labled chip and you deserve an rma. Ever way, if the chip doesn't work in a seperate motherboard (try a different company, I never liked MSI, I have one myself and its pretty crappy) as different companies have different bioses, and it might just be that MSI doesn't support the 4600 the same way that when the asus crosshair came out it didn't accept the 4600 either. Either its the board or a growing trend that the 4600s have problems

I agree with the help me thing, as I know how annoying it was when no one responded to my help me post, so I try to help others so they don't end up stuck like I did
