CPU Showing as 800Mhz (AMD Engineering sample) after new Mobo installation

Hello,

I recently had some trouble with PC and had to swap my motherboard. Before I updated it was showing the correct CPU AMD Ahtlon 3700. I changed the motherboard to an ECS GS7610 (yes, I know its budget). Anyway now my CPU is running at 800Mhz! And it is showing as such in CPU-z. It is not an ES CPU but it seems the board has some trouble recognising its full speed. As far as I can see my mobo should support this CPU without trouble.

Here is a snapshot of CPU-z on my system


I have updated to the latest BIOS but it doesnt make any difference.

What options do I have?

As far as I see I have these:

-Buy a new motherboard
-Overclock (if possible, is this possible?)
-Change some BIOS setting, which one?

Any advice is appreciated.

Thanks.

PS BTW ignore my sig, I don£t run that PC anymore :)
 
It could be your CPU downclocking when not in use. Does it return to normal speed when you load something CPU intensive?

Also, I think your Multiplier is wrong, I think (somebody correct me if I'm wrong) it should be X12.

Hi,

Thanks for your reply.

The multiplier is wrong. It should run at 12 as standard but it's stuck at 4. It doesn't change under a heavy CPU load, the system is running quite sluggish.

It seems the board I got, which was advertised as supporting SKT 754 CPU's (and not more specific ) doesn't recognise the Athlon 3700+ and labels it as an engineering sample, I don't care about this part but I do care that it only runs at 800Mhz!

I have have changed the core speed to 220Mhz so I get some extra speed but I need to change the multiplier to make any real difference. I can't see an option in the BIOS to do this and I can't find any software that works for my system.

Can you think of any way around this issue?

Thanks agian.
 
The only reason I can think of for such behavior is the motherboard simply not supporting the CPU... you might have a board with an outdated CPU (though it would have to be one really damn outdated BIOS not to recognize that CPU, it's about 4 years old now). It may be other BIOS glitch too that may require you to flash a new BIOS.

And is it really a socket 754 CPU?
 
Have you looked everywhere in the BIOS for the multiplier options. It's normally under advanced CPU features, or something along those lines.
