Ok im working on a KM400-M2 V3.0 that was bought from ebay And it came with a Amd mobo Athlon 2800.
Well whats happend is the person isntalled the bios (wasnt needed :s) from ECS http://www.ecsusa.co.../...=52&LanID=9

And the result is it comes up with a Uknown cpu type error now. Ive tryed installing some of the other Bios there and this one V1.0G http://www.ecsusa.co.../...=52&LanID=9
Seems to pick it up correctly as a Amd mobo athlon but its running at the wrong speed, Runnin at 797mhz. Is there a way to fix this? Here is my bios settings if it mite help any.
This worked completely fine before the bios was messed with, as to why they ever mest with it is beyond me. im just trying to fix it. But im out of ideas, I dont really know alot about Bios just a basic understanding.

The first thing I would do is clear the cmos and load the bios defaults then save and exit.

If still not seen correctly enter bios again and set the fsb to 166mhz.

Make sure you now how to clear the cmos before making bios changes just in case the computer won't boot.

Your motherboard manual will explain how, also check the manual to see if there are jumpers to set the fsb/cpu frequency

Thx for the reply, i have reset to defualts, to optimized defaults. ive also tryed reseting it using the jumper. but no luck.

i dont think changing it to 166 mhz would help my cpu, it runs at 266mhz and needs to be set at 133mhz as it is.

Cpu info found from google

NEW AMD MOBILE ATHLON XP-M 2800+ PROCESSOR (CPU) - AXMJ2800FHQ4C - 360538-001 PROCESSOR SPEED: 2.13GHz BUS SPEED: 266MHz L2 CACHE SIZE: 512KB COMPATIBLE

Ok I see its a mobile processor, must have missed that, you are correct it is 266mhz processor.

Alot of times bios won't recognize a mobile cpu correctly and you have to manually set it, try setting the fsb to 133 and use a multiplier of 16. Thats the stock settings

133x16=2.13G

AXMJ2800FHQ4C,,,,,,, are you sure these are the numbers that were printed on the processor?

Yup those number were gotten directly from the cpu then looked up in google.
As to changing the multiplier how do i do that? Ive missed that in the bios i guess...

Yes I googled the numbers too thats how I found the multiplier is 16 for the 2800 mobile.

Look around in bios for the multiplier and see what it set at, some chips the multiplier is locked but because this is a mobile chip I don't think it is, I know the 2500 is not locked.

I have to find your manual, I'll see what I can find

Find the JP8/JP9 jumper on the motherboard make sure the JP8 pins 2&3 are coverd with the jumper cap and the JP9 pins 1&2 are coverd.

In your manual I don't see anyway of changing the multiplier but under "Frequency/Voltage Control" Make sure the cpu clock is set to 133.

don't forget to save when you exit

Thanks for the help Dolby, I have already checked the JP8 & JP9 jumpers and they are correct. and the cpu clock speed is correct.

It has to be the multiplier that is wrong then because the bios is not setting that correctly must be setting it at the 12.5 desktop 2800 requirers and not the 16 that the mobile does.

Install everest

everest

Its free and will give you lots of usefull info about your computer, on the tree on the left open 'motherboard" then "cpu", I would like to know what the cpu is recognized as.

It may also tell you what it is setup as something like 12x 133.

This won't help you but it would be interesting to know

On battery powered equipment the processors are often run at a much lower speed to save power. So there may be no error as far as the actual speed is concerned. For the type of CMOS construction used in computer chips the speed/power ratio curve is almost flat.

Hey great program Doby, very usefull.

Tyger thats nice to know, but other than the little battery for the cmos. This dont run on a battery as its a desktop and is constant Ac power.
