Title:

Logic Board Firmware shows Wrong Speed

Text:

I recently bought a replacement 2.0GHz logic board for my a1150.

The logic board boots fine, however About My Mac only reports 1.67GHz for the processor speed (Yes it is a 2.0/2.2 GHz logic board based on video type and memory.)  Also the fans will not spin up after boot (They do the test spin), though in testing them outside the system they work fine.  Bootcamp shows an issue with the firmware revision, and I am unable to either update or roll back the firmware.

BOOT ROM Version: AAPLM011.0031.B00

SMC Version 1.2f7

I am at a loss beyond sending the board back and getting another one.  Any suggestions?

MacBook Pro 15" Core Duo Model A1150
