A7V8X-MX KM400 MB & AMD MOBILE ATHLON XP 2400+/266 Problems

[site4sure]

Hi,

I am working on helping a friend build a computer for himself. We bought the A7V8X-MX KM400 and a ATHLON MOBILE XP 2400+/266 Processor. The specs say that the MB and the proccessor are supported and also that the proccessor is suppose to clock at 1.93 Ghz. Sadly enough it only shows up at 987 in Windows and 1000 when it boots. I have messed with the jumpers, done a BIOS update and everything. The silly thing only clocks at 1K megahertz. Anyone have any suggestions for help?

I would have said it sounds like a front side bus jumper setting issue but even set at 100 (should be 133) it would be showing a higher CPU speed than this.
Because this is the case I would suspect that you need to update the motherboards bios (flash) to except this CPU.
It might well be unusual because you are using a mobile chip on a desktop motherboard?
Let us know how you go on.

Replying helps further our knowledge, without comment leaves us wondering.

Hi,

Done both of those. It shows a slower speed when I move it down to 133 and right now it is at 166 and it is showing the highest I have seen yet, which is the 1000 mhz. I have also flashed the bios and that did nothing either. Anyone else?

This may be due to Speed Step Technology. I am not too familiar with this but it may be worth you looking into. As you stated this is a "ATHLON MOBILE XP 2400+/266 Processor". I believe they are designed with Step Technology. This basically means they run at a lower clock rate and lower voltage when they sense full power is not needed. This is to keep it from running too hot all the time and overheating also to save the battery.
Anyway, worth looking into.


Hope this helps.

Good question. My info shows all the 2400+ mobil procs clock at 2000Mhz. I've only seen one mobil on a desktop mobo and it worked out just fine.

I wonder if the motherboard is seeing a 6 multi instead of a 15 multiplier.

you will have to use cpumsr to change thr muli to the apropriate #. i was looking here to see if there was a better
work around as my 2500+m boots as a 1000 as well. i set the fsb to 185 but it was unstable. i have an ideq200v that
runs the voltage at 1.57 to start,instead of 1.45 i went with the mobil for low power/quiet but its just not wokin out

Mobile xp 2400-m boots at 6 * 100 .
(have one myself on abit NF7-S)

Via chisets have problems with mobile as they cant control the multipliers as abit and other nforce board can with 5bits fid having all multipliers upto 24.

You can use the wire trick , setting a wire in the cpu socket under the cpu to set the default multiplier that
it shall start up with .

Or you can use the software to ajust the processor from within windows .
