Was checking around to see some benchmark results of OWC's 6gb kit (4+2) when I checked apple's site to see what they officially offered as upgrade options -- http://store.apple.com/us/memorymodel/ME_15_2_66_MBP

Apple Memory Module 8GB 1066MHz DDR3 (PC3-8500) - 2x4GB SO-DIMMs

Does the early 09 UMBP support 8GB now? Anyone try this out? $1200 is kinda steep, but 349.99 for a 4GB x 2 from OWC isn't so bad. Why doesn't OWC offer this as an option?

*sigh* not this again. NO NO and NO! The 15 inch unibody mbp does not support 8 gig of memory. And 6 gig of memory is not worth it and makes no difference, not to mention you lose dual channel. Next time do a search.

Dude, chill out. If you don't like the post, don't respond. Or just don't open the thread because you already knew what is was about by the title.

i totally disagree. 6GB makes a pretty big difference. its the dual channel that doesnt really make that big a difference. it really depends on what you are doing, but it definitely does make a difference

Did you look at the link? Why would Apple sell 2 x 4GB specifically for the 2.66 15"?

Perhaps there was more of an update to the higher-end 15" than merely a speedbump.
 
Lets get this cleared.

ALL 15" UNIBODY MBP CAN TAKE A MAXIMUM OF 6GB OF RAM.

ALL 17" CAN GO UP TO 8GB OF RAM.

Relax man. No one put a gun to your head to respond. I think the posts above show others have an interest.

I'm just wondering why apple.com would have a $1300.00 upgrade listed on their site if it doesn't work with the product.

Has anyone tried this in one of the new speed-bumped UMBPS?

You happen to see any benchmarks? I'm just looking for some hard numbers to make my decision.

I upgraded my C2D Mini to 4GB even though it only addresses around 3GB just so that it runs in dual channel mode. Is more lost than gained by upgrading to 6GB and losing dual channel in the UMBP?
 
I thought DDR3 is Tri-Channel? So you'll need 3 modules to get the best performance? Because I've seen core i7 kits come with memory modules in sets of 3s. like this

If that's true, and please correct me if it's false, than (2x2GB) and (2GB+4GB) would be the same speed, because neither option is tri-channel enabled...
 
I wouldnt get too excited anyway. I read in various articles that even the 17" mbp doesnt benefit much from 8gb of ram due to each cores not being able to handle more than 2-3GB at a time. And that in actuality in most cases the 6GB runs and utilized much better.

I think I read it in toms hardware, bit-tech or ANandtech, cant remember found it in an hours search of googling somewhere. A quad core notebook should be able to fully handle and utilize the 8gb of RAM though.

it really depends on what you are doing. if you are gaming and running apps that are memory intesive then it will not make that big a deal to you. but if you are using apps that are running block sizes greater than 4MB then it will make a difference when running real time software.
