Mixing CORE-STEPPING and upgrading CPU configuration (XEON)

[idata]

Hello,

I have a xSeries 226 servers: NAME: IBM eServer x226-http://www.ibm.com/developerworks/forums/ 8488ECG- MB: MSI-9151 with this CPU installed: S-SPEC: SL8P6 CORE-STEPPING: R-0 CPUID: 0F4Ah FREQ: 3.0 GHZ BUS: 800 MHZ CACHE L2: 2 MB Core: Irwindale (?) Now I'm trying to add a second cpu: Spec: SL7ZF CPUID: 0F43h CORE-STEPPING: ??? FREQ: 3.0 GHZ BUS: 800 MHZ CACHE L2: 2 MB

My First question is: Is possible to mix this stepping on a single server?

----> i've tryed to add the second processor and.... When powered up, all the fans would spin very fast and nothing else would happen, but with a single cpu installed things it works. ----> I don't have a VRM ( Thanks to IBM manual ) So i have buyed this VRM: Fru 24R2701 / Lite-on P/N DD-1151-2C Rev A

My second question is: This VRM is compatible with my hardware?

I don't find any information in IBM documents, please help me.

And, excuse me for my BAD english

When installing 2 Intel® Xeon® processors, both processors most have the same spec number, in this case either SL8P6 or SL7ZF, but both processors most have the same one, otherwise the system will have unexpected behavior.

Regarding the VRM, please contact the VRM manufacturer for compatibility information.
