Does it work?

I previously had read it was capped at 6GB but recently have seen posts saying that 8GB now works.

Has anybody actually done it? Is it working?

Thanks
 
My son has the 15" and I bought him some Ram for Christmas from Crucial. I had heard the 6 GB limit as well and that was what I was expecting, but sure enough, it recognized the full 8.

BTW, if you are running Parallels, upping the machine to 8 and then using Parallels to allocate 3 or 4 gigs (XP can't recognize more than 3) to Windows made it run almost like it is not in emulation.

I have never read that 8 works in the aluminum MacBook, but 8 DOES work in the 13in MacBook Pro.

I believe that 6 is still the limit on the Alu MacBook
 
Well I just ordered it for $74, so we'll know for sure by the end of the week I guess.
 
I believe much of this is driven by the chipset (not the CPU), which varies by model. Best to communicate with someone who can verify before ordering. My 2007 AL MBP 15 max'd at 4GB. 2008 unibody MBP 15 won't do 8GB, but my 2010 unibody 13 MBP has 8GB in it, no problem.
 
Bummer, that was actually the reason I got rid of my 13in a few months ago, I needed more RAM for VMs.
 
Yes, it works great, I'm posting on my upgraded Macbook right now...

Nope, it's 8 now. Unsure if this is due to SL and/or an EFI update, but happily using 8 right now...
 
Do tell if it works, and what brand.

I have a 15" late 2008, and it's at 4GB now.

A few days ago I bought this kit:

Mushkin Essentials 8GB (2x4GB) DDR3 1066MHz CL7 SODIMM (996644)

and it didn't work. Pressed the power button, it started beeping loudly, and no boot. Even tried a 6GB configuration and same thing. My 2x2GB Mushkin kit worked fine for the past year and a half, but the 8GB kit doesn't.
 
May I ask what brand you are using?

It's from Crucial.

To be very clear, I'm talking about a MacBook5,1 model. It's the aluminum unibody with core 2 duo at 2.4 GHz.

To the other poster who was wondering why 8 Gb, it's easy to eat RAM at a high clip using VMs. When I has 4 Gb I was getting a lot of pageouts.

Plus, RAM is soooo stupid cheap right now that it's an easy and cheap thing to do to get better performance.
 
I too can confirm 8GB ram (I have crucial) works in the Alu-macbook 2.4ghz

I have a 13" MBP 7,1 2.4GHz, with 8GB. At 4GB, it rarely paged out with Mail/FFox (20 tabs)/Word/PPT/Cal/AddrBk/Preview running. Even the occasional PShop, no problem. Add in Fusion, and it always paged.
BTW, on my MP, 8GB is barely enough, but I run more. And Fusion always kicks it into swapland.

Bought my RAM from OWC. 4 months ago it was $150, but now it's less.
 
2.0ghz model

Am I correct to assume that this will also work on the 5,1 2.0ghz model as well? Everyone in this thread appears to have only tested this on the 2.4
 
8GB RAM works on the 5,1 2.0ghz model. I know this because I am typing from it right now -- been over the 6gb "limit", and it has been rock solid stable for the last 14 days since I put the RAM in. The exact RAM: Kingston Apple 8GB Kit (2x4GB Modules) 1066MHz DDR3 SODIMM iMac and Macbook Memory (KTA-MB1066K2/8G)
