3gb limit

[JamesM]

Whats the limiting factor, its not the OS and it physically fits so why will my MBP only see 3gb?

You haven't told us what laptop you have, but I'd go with the limitation is a combination of the core logic chipset and firmware.

Chipset if you're seeing something like 3.3GB of RAM. Some more information would be nice instead of being incredibly vague.

Sorry laptop is in my signature, C2D 2.33Ghz.

It currently only has 3gb in it as I've read quite a few times that it will only see 3gb which seems strange to me, an OS or slot limitation would make more sense but it can't be either of those.

Hardware limitation, no? Not software.

Limitation is due to MOBO hardware, not due to software.

You need Santa Rosa or newer to access full 4gb.

No, he needs the Crestline chipset to access 4GB. Apple has never nor will they ever sell a computer using the Santa Rosa centrino platform.

Your MacBook Pro has a 32-bit chipset. The Crestline chipset is 64-bit.
