I have a late 2008 2.4 uMBP. Now people say the higher 15" uMBP and 17" uMBP have a different motherboard. I would like people to post their uMBP model and what motherboard they have. Also I would be interested to see for the new 2009 range including the 13". The 2 reasons I am curious is for that SATA debate, 1.5GB vs 3.0GB. The 2nd reason is the 8GB RAM issues. Apple sell 8GB for certain 15" models etc and 17" (do they actually work PROPERLY cause people who have tested 8GB have had problems or is that only for base model?). If you go to system profiler and click Serial-ATA, it has nVidia and gives product name, I think this is my motherboard model nvidia mcp79 ahci (if not how would I find it).
