AMD 955 BE Hilarity

[MacPasty]

I'm just plain confused. And I'm laughing. Could be that I'm tired. Could be that my AMD 955 be is now only showing 3 active cores and is labeling itself as a 775 BE, a chip AMD never made... Not quite sure what going on here and would love to have some insight as to how this came to be. THanks!

No idea, I'd try resetting BIOS to defaults, and see if it fixes itself. If not, sounds like it is broken...

Did this machine go on a trip? One time my cpu got unseated in transition...

If you're not sure how to do that, go to your motherboard and remove the watch battery and then put it/ a new one back in.

No need for that, there should be a jumper to move on the motherboard to reset cmos

You learn something new every day! I'll try looking for this on my board. :thumbsup:

If it's not mentioned in the motherboard manual, it probably doesn't apply to your mobo.

Wow I wonder if it's a dead core. I've never seen a CPU survive degradation before. This could be a scientific marvel! Send it to AMD for analysis! 😀

well that is my thoughts a core died!?!?!?!?
but the change of the cpu is a bit confusing
how the mobo takes the name of the cpu???
counts the cores of the cpu??? that will explain the strange naming of the cpu
to a non existant one

I don't think AMD's hardware is smart enough to tell when a core dies. It has always been based on the CPU being told which cores are to be active.

Maybe your BIOS got corrupted? I would suggest going online to check for a BIOS update, and flash the BIOS update. I think the names for the CPU are kept in there, and the motherboard will try to pick the right name from that.

So, although your motherboard could be faulty and the BIOS is fine, it's just so much easier to install/flash new BIOS. Try that, and if you still have the problem, then you can take further steps to diagnose if it's a hardware fault in the motherboard and/or CPU.

Maybe a friend or sibling swapped out your CPU for a cheap Chinese knock off? Lol

The model name depends on the core count, so if for some reason a core got disabled I could see it changing the model name being displayed.

See Table 16/17 (NC is the number of cores on the processor - 1).
