Cannot get the bios (A12) to recognize 2nd CPU
I have a problem with my 1600sc. I have Xeons 533 fsb. I have two identical SC1600. I pulled one CPU from one machine and added to the other.
I cannot get the bios (A12) to recognize the 2nd CPU. In Windows device manager I can see the secound CPU (Show as working properly).
Has anyone else had these problems?
- Does the motherboard need a VRM as well as a processor? I dont think it does as I recall the VRM is built onto the motherboard.
However the "S" spec must be within the range that the bios supports.
Mixing different steppings is not recommeded.
What are the S spec for each CPU? - I am experiencing a similar issue with the second cpu being recognized as a 2.6 vs a 2.4/533fsb. Same issue existed with older bios a08 and newly flashed bios a12. This is pertaining to a 1600sc with factory hardware.

I recently saw this on a PE1750.
I had moved a drive running Windows 2008 from a dual 2.4 to a dual 2.8 for testing purposes. The bios was seeing the cpu's correctly, but windows saw it as one 2.4 and one 2.8 (actually 2 of eac)
I went into the device manager, uninstalled both 2.4's and renbooted and now windows ees them all as 2.8's
