8GB of RAM in a Unibody Macbook Pro?  Yes, but...

I know all this Mac stuff is off-topic for SharePoint readers but I get a lot of comments from other Mac users here so I thought I would post my experiences on a confusing topic. When I bought the new Unibody Macbook Pro back in October I did so with the hope that I would be able to install 8GB of RAM in the machine for virtualization purposes. I knew it wasn’t officially supported but I was hopeful; as DDR3 4GB SODIMM’s weren’t widely available yet I couldn’t really test it out at the time.

I now have conclusive results for other Macheads out there. The first generation Unibody MBP’s - 2.4GHz, 2.53GHz, and 2.8GHz models - do not reliably run any more than 4GB of RAM. Some people have had success with 6GB (one 4GB chip and one 2GB chip) but, using Apple’s own ridiculously overpriced 4GB chips, I could not get my 2.53 model to stabilize above 4GB.

Recently, Apple bumped up the specs on the 15” MBP’s to match the new 17” models; specifically, they now only offer the 15” in 2.66GHz and 2.93GHz models (the 2.93 can only be ordered online). Assuming that the firmware on the 15” had been updated to match the 17” board I bought a new 2.66 model and slapped the 4GB RAM chips into it. Success! I am now running 8GB on my 15” Unibody (and yes, I’ve stressed it up over 7GB utilization using VMWare Fusion and it works fine).

Somewhere along the line in my research I found a thread indicating that the motherboard revision numbers changed from the first generation to the second generation but I can’t find the thread now and I don’t see any markings on the greenboard to confirm or deny this. All I can tell you is this:

* The 4GB limitation in the first generation Unibody’s is *not* a Leopard issue. Leopard works just fine on my new 15 and the 17’s.
* You *must* have the 2.66 or 2.93 model to run 8GB (unless Apple releases a firmware update to fix this).
* SOMETHING is different between the first gen and second gen, either the actual hardware or the firmware, but there is no doubt that they’re not the same.

Also, I think you would be better off waiting for RAM prices to come down or, if you must have 8GB now, buy it from Crucial, OWC, etc. Apple’s price is just nonsensical (I had a credit to use so it didn’t hurt me quite as bad; full retail price is $1,200 in the US).

Now back to our regular SharePoint programming…

UPDATE: Not sure why but someone asked for a screenshot to prove this. You can't really tell it's a 15" (unless that's what MacBookPro5,1 means) so you'll just have to take my word on that.

Apparently, we still have some skeptics in the audience. Here's a screenie of Activity Monitor showing nearly all 8GB being used. And, yes, this *IS* a 15" MacBook Pro and *not* the 17" version.

Another screenshot please

The problem is that all MBP can see 8GB RAM, but they can only use the first 6GB. After that, the system gets unstable.

Can you make a screenshot of Activity Monitor using more that 6GB (a virtual machine running will help)?

what about the 2.8ghz MBP 15"

I have the 2.8ghz 15" Unibody MBP running Vista X64 on a partition. Any idea whether I would be able to run 8gb of RAM on it?

RE: what about the 2.8ghz MBP 15"

Theunis,

I'm afraid you're out of luck.  The 2.53 and 2.8 1st gen Unibody MBP's have the same chipset and are unable to handle 8GB.  In fact, a friend of mine who has a 2.8 just tried to do 6GB and was unsuccessful but I've heard varying reports on that front - you may or may not be able to get 6GB to work but 8GB is out of the question.

Apple Burns First Buyers of Unibody MBP

My feeling is that Apple burned many first buyers of the new unibody macbook pros. I bought mine in January '09, and less than 90 days later they release a new model that is capable of handling twice the RAM.

As per recent conversations with apple, your statement above is absolutely correct - 1st gen Uniody MBPs are not able to handle more than 4GB of RAM. March '09 and later models have a different motherboard - thus the differences in capabilities.

As I said to Apple, had I known you were releasing a new model within the next few months, I would have waited 90 days on my purchase to get twice the RAM. Apple's response - Sorry, but you still have a nice machine. And... No, you cannot upgrade, exchange, or trade-up your current model for a new one. If you would like the new model, it is available for purchase online or at any Apple Store.

Needless to say, I am not happy with Apple.

Re: 8GB of RAM in a Unibody Macbook Pro?  Yes, but...

It would be interesting to see if 8GB now works in the first generation Unibody Macbook Pros with MBP51.007E.B05. (It is newer than the firmware shown in the screenshot.)

Has anybody tried it?
