MBP 2.33Ghz - 4GB RAM possible in Leopard?

[EmptyG]

Hello everyone

So I have the last version of the MBP (before the SR updates). It's a 2.33Ghz, 2GB of RAM.

My question is this: I have been reading about the 3GB RAM limitation and had seen people mention that OS X currently won't recognize above 3GB total on my specific system, and that may be due in part to OS X being 32 bit right now.

Leopard will be 64 bit out of the box. Will my version of the MBP recognize 4 GB of RAM then, or is this system always going to be limited to 3GB?

And is it worth going to 4GB anyways, even if my system will always only recognize 3GB max?

Thanks!

the 3GB limit is a motherboard design limit, Leopard won't help.

And the reason to still put 2*2GB in there instead of 1*2GB + 1*1GB is that they will still run in dual channel mode and therefor give you twice the memory bandwidth. If you only put in 1+2 you will only get half the memory bandwidth.

Thought it sucks to know that you have ram you can't use =P

Just live with 2GB as long as you can, it should work for quite some time shouldn't it?

For the extra money of 2 + 2 you get a small additional performance gain in real world terms over the 2 + 1 configuration. Double bandwidth means only 6 - 8 % in overall performance.

Excellent responses all Yeah I will just work with the 2GB for now. It's fine right now and should be enough for the foreseeable future, just wanted to know my options down the road.

Thanks!
