A7N8X-X won't recognize my AMDXP 2600 333 as a 333fsb chip

When I finally got my new computer up and running, it autodetected the processor as having a 200 mhz frequency, yet it is a 333 chip (I checked the OPN). I have tried everything I can think of (which isn't that much).

So here's what I have:
AMD XP 2600 333
Asus A7N8X-X mobo
2 256 megs of OCSystem ram OCSystem 256MB TRUE PC2700 333MHz CL2.5/CAS 2.5 DDR
Sound Blaster Live Value
Buslink Burner
WD 40 gig hard drive
400 watt power supply
WinXP home

The processor is water cooled and is not over clocked. I have artic silver paste on the water block.

Anyway, I have contacted the distributor of the processor, mobo, and ram, as well as Asus and none have provided any helpful feed back as of yet. Any insight would be appreciated.

Oh yeah, I have the 1006 bios running.

Thanks in advance!
 
Just change FSB to 166Mhz and you're ready. My barton came at a default 100mhz in the bios.

Welcome to AT forums 😉
 
"Just change FSB to 166Mhz and you're ready. My barton came at a default 100mhz in the bios."

I did that and when I f10'ed and saved cmos, it wouldn't boot. So I had to power it down, then reboot. When it got passed the memcheck, it said that I needed to set the correct processor speed. Any thing below 133mhz works. Any other ideas?
 
I haven't used that board, but if the bios is similar to the nF2 boards I've used go in the bios and set system performance to expert, memory to 100%, fsb to 166mhz, save&exit. Also, you are certain you didn't get a 266fsb version correct? I'd set the multiplier manually just to be certain.
 
I checked the OPN on the chip with AMD and it is infact a 333 chip.

As far as setting the bios, the option is there. I can set the option all I want, but it just won't boot afterwards. In talking with the Asus tech, he didn't seem to suggest that updating the bios would fix the problem, but I'll give it a shot this evening.

Thanks for the input.
 
So I think my friend and I fixed the problem. Apparently, I needed to manually set the bios to accept it by changing the "CPU Frequency Multiple" to 12.0 instead of 8.0x/16.0x. So I think the problem is solved... It just bothers me that the bios didn't auto detect the settings.

Anyway, thanks for the welcome and input.

I have built three computer using this board.

Anyways, quite often you'll need to change the multiple on these AMD chips if it doesn't detect right since they are multiplier unlocked. This is a VERY small price to pay (having to change *one* or maybe two settings in the BIOS) for the versatility we gain from having fully unlocked AMD chips.
