Windows wont boot with the correct FSB

[beansbaxter]

The computer boots up and reads everything correctly. When it begins to load Windows, it reboots the machine. When I downgrade the FSB, Windows will load up just fine. I dont know what to do.

The hardware is:
Epox 8K9A7I mobo (KT400A Chipset)
AMD Athlon XP 2700+ 333Mhz FSB
Kingston PC3200 DDR Memory

When I set the FSB in the BIOS to 166, Windows will not boot.

If I downgrade the BIOS to 133, Windows will boot up correctly.

The BIOS has been updated, and I have tried everything and dont know what to do. Please help????

On a side note, when I try to boot into XP under Safe Mode to see where the hangup is, it stops or reboots at the line that states:

xxxxxxxxxx/windows/system32/drivers/mup.sys

I have this problem no matter if I am installing or loading XP.

What power supply are you using (brand/model)?

where did you get the cpu? was it from a reputable source?

Yeah the CPU is fine, bought it from Newegg.com and pulled it out of a working machine that I recently upgraded. The power supply from that machine followed the processor as well, just an Antec 480watt PS.

I ended up ordering a new mobo, an Asus this time around. But I dont know for sure yet till it arrives if that will fix it. I might have to RMA the Epox mobo.

Unless anyone has any other ideas? Please...anything?

Update:

Well I finally just assumed I must have a bad mobo, so I purchased a brand new Asus A7N8X-X mobo and installed it. Set the FSB to 166, it reads the proc correctly, but I am getting different errors during the Windows XP install, and it hangs up (just with a different error in a different spot).

Anyway, I dropped the BIOS back down to 100, it installs Windows ok. I put the BIOS at 133 and it works fine. Put it up to where it should be at 166 and it hangs up every time.

I've tried using a Windows XP Pro CD and an SP2 Slipstreamed Windows XP Pro CD, and both are not working.

Any ideas???

Have you manually set the timings on the ram or is it "by SPD"?

The speed is set auto "by spd" which is a cas latency of 3t. Do you think that might be the problem? Do I need faster mem in there?

Well I pulled the memory, dropped in some Kingston 2.5 CAS in there and same problem. So I pulled the proc, dropped in an AMD Sempron 2400 333FSB in there and now Windows seem to install ok. The FSB is the same which I didnt think would make a difference. If it all works, then maybe it was a bad proc which doesnt make sense cause I pulled it out of my other good working machine.

have you let the bios have a brand new shiny update?

When you pulled that XP2700 out of a working maching what FSB was it running at ?
Also what voltage is being detected by the bios that the cpu is running at ? try adding more vcore ?
