P4B266-C with a P4 2.6G ??? HELP!!!

[Walt]

Has any tried a using a P4 2.6G 400MHz FSB CPU in a P4B266-C motherboard?
Does it work????

I am trying to upgrade from my original 1.6a GHz CPU to a new 2.6 GHz, and the
new CPU will not boot; not even into BIOS.

I checked the ASUS website (http://taiwan.asus.com.tw/inside/techref/northwoodcpu.htm),
and I believe the P4B266-C will support a 2.6G (the fastest P4 with a 400 MHz FSB) as
of BIOS v1005.002.

I have the latest BIOS out of ASUS Germany, v1007.003 dated 12/08/2003 (fairly recent).

My new CPU has an sSpec of SL6PP. I check on Intel's website, and this is indeed a
2.6GHz, 400MHz FSB, CPU.

When I replace my new CPU back with my old CPU, and boot, I go into BIOS and it
says that a multiplier error was detected, and I am in now "safe mode" (or words along
those lines).

Any suggestions would be appreciated.

According to the asus website it only lists the P4-2.20 GHz(400 MHz FSB) as
the max speed processor for your board...

You are right, but it depends where one looks.

The CPU Compatibility pages do say 2.2GHz.

The FAQ's pages for this MB say 2.4GHz.

And in the TechRef pages say 2.6GHz.

I had assume that some pages in their website were older than others, and that
the TechRef page which stated 2.6GHz was the newest and most current.

Ah, well....

Also, check out: http://65.68.55.12/inetpub/ftproot/asus_northwood_support.htm
and http://www.asus.com/inside/Techref/Northwood CPU P4 2.8G .htm
_BOTH_ claim 2.6G. However, it is seeming more and more, that these webpages
are simply wrong and that the 2.6GHz CPU can't work.
