Max ram for a MBP?

[Luis Ortega]

I was reading that the MBP can take more than 4 gb ram. Is this true?
I have a 2007 SR MBP with 4 gb ram. Is it possible to put in 4 gb module and a 2 gb module to make 6 gb, or maybe 2 x 4 gb modules to make 8 gb?
If this is possible, will Snow Leopard improve the ability of the computer to use more ram or more cores?
Thanks for any advice.

There was a massive thread about this with 1000s of replys. Never read it but something along the lines of can take 8GB but 6GB is better?

Have a search see what you can find... if not try google!

Your macbook pro can take 2x2GB DDR2 memory, and that's all. Snow Leopard will not change this, its a hardware restriction. Leopard can address at least 32GB in a mac pro tower, its not a software issue as to how much ram you can put in your mac.

I've read in crucial.com website that the maximum amount for the MBP is 4GB (this generation, or the previous 3 ones) the only difference is that the new one carries DDR3.

As for the Snow Leopard thing, no it will not change that fact. The improvements that 10.6 will have are performance-wise.

Based on the Open-CL standard Snow Leopard will be able to use the GPU as another CPU, so if your Mac has a powerful graphics card, you will get a great performance boost.

FAQ:

Will my MacBook Pro support up to 8GB?
- Only the Santa Rosa and Penryn (MacBook Pro 3,1 and 4,1) can support this much memory. The MacBook Pro 2,1 only supports upto 3.25GB ram accessible so adding in 8GB wouldn't matter since you can only access >4GB.

- Currently, OSX Leopard (10.5.x) seems to have trouble accessing above 6GB of physical ram. Further testing is being done, but currently, 6GB is the max that is considered "safe".

You can go up to 6GB of RAM.

I'm selling mine if you're curious (cheap!)

so the new unibody MBP can use 6GB?

Yes. That's what was said.

Yes. That's what was said.

I thought this chipset only supported 4... I know that 6 will be recognized, but can it all be used?

It's 64-bit. 4GB isn't even the beginning of the end.

Apple's built in a barrier on getting 8GB to work (I'd say, "At all," but it'll work for about two minutes before it crashes), but 6GB is fine.

Benchmarks show that 6 GB works just fine. 8 GB apparently results in problems...

This is wrong. Apple will only support 4 GB, but Santa Rosa MacBook Pros work fine with 6 GB. I have one, equipped with 6 GB. It recognizes and uses all 6 GB without any issues. It's a big help when running multiple OSes at once.

I have never tried it, but numerous users have reported incorrect operation with 8 GB installed both on SR and Unibody MBPs. Apparently, if you have 8 GB installed, the system will slow to a crawl once you use more than 4 GB.
