Processor problem with DL360

Any way to get around have 2 cpus with different steppings in the same box? Will performance be affected?

Re: Processor problem with DL360

Hi Greq,
Processor steppings are versions of the same processor model (for example, the Intel Pentium III Xeon processor) that vary only slightly, usually to improve performance or manufacturing yield. Each stepping requires changes to the system ROM. For each processor stepping that it produces, Intel provides a microcode patch for inclusion in the system ROM. Each Intel processor stepping has a unique CPU ID, and its microcode patch contains that same CPU ID. Within the system ROM there is a table where the microcode patches are stored. Compaq and other server vendors must continually add newly released Intel patches to keep their ROMs up to date. If a processor is installed in a ProLiant server whose current system ROM does not contain the correct microcode for that processor, the ROM generates the following error message to prevent the user from operating the processor with the wrong microcode:

UNSUPPORTED PROCESSOR DETECTED. SYSTEM HALTED

The processor with the lowest stepping is installed as the bootstrap processor.

I'm not aware of any performance loss.
