I'm building a new comp with a Athlon XP 2700+ and a Asus A7N8X mobo and a 9700pro
When i turn on the comp and it goes to the post screen it says my floppy test failed and I have a thlon XP 1500+ ?!?!
I tried to change the FSB to 166 and the multiplyer to 13, but when i save, restart, and go back to the post screen it says: "WARNING! CPU Have Over Speed!"
I tried to ignore that and Put in my XP bootable cd.... and before it started it said some file was corrupted. So i guess it's the cd...i'm getting another one.
But can somebody please give me some ideas on what to do as far as bios settings ?
Thx for your time!

Hmm, the XP1500+ ran at 1333MHz, and 13x100=1300, so my guess is it's seeing the multiplier, I would leave the multiplier on auto mode. You do need your bus speed at 166MHz however.

What memory are you running?

2 pieces of CORSAIR MEMORY XMS Extreme Memory Speed Series 256MB 32MX8 PC-3500C2 With Heat Spreader

PS. When i put it on Auto it changes the FSB to 6.5 fro some reason.

Well, I think know your problem now. It's likely the infamous A7N8X PC3500 BIOS bug. You're lucky though as many people have been unable to get the thing to boot a second time without removing the BIOS battery to clear settings!

You need to manually configure your memory. There have been many, many, many post in the Motherboard's forum telling you exactly what to do. I think it involves setting it as DDR400 and "aggressive".

The board is giving you the CPU Overspeed error because it assumes that's what went wrong during a failed boot. The true failure is in the BIOS' ability to understand the SPD values of PC3500 memory.

Well now, that's a horse of a different color! OK I'd still try manually configuring your RAM, manually setting your Bus Speed, and leaving the multiplier on auto.

make sure you have 1002 bios installed, I have xp2800 and that Asus board, and for some FuKn reason it will not run stable @ 166 fsb, only on 133.... system hangs and doesn't get past the Windows XP screen ....

I got an Asus A7N8X. I had the exact same problem with my Duron. It would post so far, and stop when it got to detecting the IDE devices. I also got the CPU overclocking warning. I am running Corsair 512 MB DDR 400. I was told to set the memory timings to 6-3-3-2. This fixed the problem. Also, it detects my Duron 900 as 100 FSB with a multiplier of 6.5. But the CPU runs at 900. Fugure that out. Good luck.
