Processor speed

  Sobeit 20:04 20 May 2006

Hi all.
I am testing my nephews amd processor in my mobo as I think his is giving up.
His processor is running fine on my mobo so it looks like I have isolated the problem.
Thing is, when I run dxdiag it shows the processor as a athlon 1600+ running at 1400mhz.
He thought it was a 2400+.
If I change the clock speed jumpers to up the mhz speed will it still show as a 1600+?
ie, if it shows AMD xp 1600+ in dxdiag, is that what the processor is and thats that?

Run everest home click here

This should give you the model number ( full speed ) of the cpu and the speed it is now running at.

Thanks ed-0.
Everest says
CPU Type AMD Athlon XP, 1400 MHz (10.5 x 133) 1600+
Now i'm confused.
It's saying it is a
AthlonXP 1600+ which has a 266fsb, yet it says it is running at 10.5 x 133??
My jumpers for the clock speed are set at 10.5 but if a athlon 1600+ has a 266 bus speed why is it showing 133?

" if a athlon 1600+ has a 266 bus speed why is it showing 133? "

Thats fine. The motherboard doubles it to 266Mhz. This is normal.

Then it must be a 1600+ you have. ;-(

I can't see how your son would think it was a 2400+

The only thing worth investigating would be the motherboard manual. When you ran everest, did you note the make and model of the motherboard.

check the cpu id numbers here click here

Hi both.
Checked the site remind, the cpu has 2400 on it.
Also, Everest says the chipset is a Thoroughbred and this site says a 1600 is Palamino?
So, we've established that it is running at 266MHz, my mobo is set to auto detect the fsb so that is sorted.
A 2400 is meant to run at 2000MHz real, so, if I change the clock ratio from 10.5x to 15x, this will bring it up to speed. Will this also change the id of the cpu in dxdiag and EVEREST?
I must be a bit careful here if it really IS a 1600 and I overclock so much.
On the other hand how can it be a 1600 if it isn't Palamino??
WOW, i'm gonna explode :-)

Do you mean the cpu has the 2400+ code numbers? AXDA2400

Can you post them here.

I would suggest posting the full numbers off the chip as ed-0 has suggested. If it is a 2400 then perhaps you can also post the motherboards name and number and the BIOS number as it is possible the reason it thinks its a 1600+ is the motherboard doesn't recognise it and there may be a BIOS update to address this problem.
