    Hi,

    Just wondering if anyone else has some major problems with the 9400 part of GFX in the MacBookPro 5,1 Late 2008 model ?? I can run Lion on the 9600 card, but switching back to 9400 gives me major GFX corruption, including not seeing the full login screen, Parallels not working correctly etc. ??

    Cheers, Jason.

    The Late 2008 MBP does not have intel graphics. You have a 9400m integrated card (better battery life), and a 9600GT (better performance). I didn't have any problems with either on Lion DP4...but have since returned to SL.

    Have you tested your ram? This might be a memory issue.

    Well that solves the 1st part of it, I should RTFM 1st ! After having the laptop for 2 years I should know better ;)
    This was after a SL upgrade. I'm wondering after a clean start all would be OK. If they are both Nvidia cards, then the same driver should be fine, and it has to be something with my current upgrade base. Damn, I really can't be arsed to go through setting this all up again . . .

    Thanks for the reply !

    A full test on 10.6.7 only, but I do have 8GB in as 10.6.7 solved the 6GB RAM plus issue on the 5,1 Nvidia chipset series. I can always pop the old 2GB DDR3 stick in again and give it a go.

    That, and you could run memtest.
