Athlon XP 2800+ recognized incorrectly

[Patt]

I have an ASUS A7N8X-deluxe mobo, and an Athlon XP 2800+ in my system. When I boot up, the CPU is not being recognized properly, showing as an Athlon 1250 Mhz, and the memory speed as 100 Mhz (as opposed to the normal 166 Mhz). The system warns me that it is set incorrectly, and to go into BIOS to fix the problem.

I do this, and reboot, and the same issue crops up again and again.

What settings in BIOS do I need to tweak?

Is this possibly a crapped out CPU or MB?

Seems like the motherboard. I had a the exact same problem but it only occured when power to the MB was turned off. The CMOS battery was dead and would keep defaulting the cpu back to 100mhz. If windows boots up fine with the correct speed I would say the mobo is wacked.

This definately sounds like a bios issue...I don't think anything is "broken". Confirm the health of your CMOS battery then reset the bios to there default settings then go back into the bios and make sure they are setup properly.

Actually, after some searching on the ASUS boards, I found that perhaps because I'm using the latest version of the BIOS, there are problems detecting Athlon XPs, because the BIOS is primarily for Semprons. I'm going to try re-flashing the BIOS tonight when I get home back to the previous version to see if this corrects the problem.

i seem to remember a similar problem with my nf2 ultra board and barton 2500, but it'd only do that sometimes when i reset the cmos jumper, and a restart would fix it...good idea, go with the older bios lol.

Why the lol?

multiplier not set properly maybe?

I'll check the settings once I downgrade the BIOS.

Roger that - had the same problem with a 2400+ xp on a different mother board. I ended up setting it manually. For whatever reason motherboards seem to be a little finicky about detecting XP's.

What exactly did you have to set manually (if you remember)?

It probably just the bios setting set wrong, check to see if the fsb is set at 166(333).

partly because i told you a small story while ending up just agreeing with someone else, partly because of the irony of the board having a new bios for better support for a specific processor, and then it ending up not recognizing your processor correctly.

There's likely nothing wrong with the motherboard or the cpu -- you just have to go into the bios and set the bus speed and multiplier to the right values and it should display the correct info.

Thanks for the replies everyone ... I still haven't had a chance to try it out. Between caring for the baby, working extra shifts and other extracurricular activities, my home rig has been sadly neglected. Tonight it happens though, and i"ll update the thread.

This problem happens to one of my computers every now and then. To fix it I just go into the bios and reset the ram speed correctly. Once that is done the cpu speed is correctly recognized on reboot.
