Not to bore with all the details but went from 6gb to 8gb this morning on my 15 in 2.93 by pulling the 2gb chip and replacing it with a match chip that I already bought from OWC. First off so far it seem to run stable without any visual issues going on. Booted right up after instal than I ran my tests. I will just give you the improvements from going from 6gb to 8gb. I have been doing tests all along in Photoshop going from 1 SSD to 2 SSD in Raid O and from 4gb to 6gb to finally 8gb. Let's just say there have been improvements going up in every category of my testing. Just from 6gb to 8gb iin a very long action in Photoshop I got just before the install 59 seconds to complete this action with 6gb after the install to 8gb this action took 54 seconds. Capture One which is a lot like Aperture to process files I shaved some time off also. Here the test was 10 Raw files to a output of 228 mgs each with 6gbs it took 3:55 and with 8gb it took 3:44 and this is basically a more processor hungry program than Ram but Ram still made up some time. My X bench score jumped up about 6 points and my Geek score jumped up about 80.

So overhaul this is working as expected and as several others on this forum said it works. To them thanks for the vote of confidence. To others these may not seem like much but as i work with very large files both in Quark and Photoshop this amount of ram will show even better improvements. I am pushing the Ram but not to it's fullest yet but everyday work it seems to be making very nice improvements. I will continue to work on things that push it too it's knees but so far very nice. Also heat and fan speed have not changed at all. Also I still am getting my blinking at me . Which is a Apple issue. I still have some permission issues in I tunes and I life products that are driving me nuts and can't seem to straighten out and frankly I give up. I hope 10.5.7 will straighten things out in that area and also the blinking issue.

Thanks for listening but I am happy and this is not a money thing. I am 52 years old and can afford to have a rocket ship in my arsenal and this is for business reasons for maxing this thing out as fast as I can get it. Next move is obviously Enterprise SSD drives but that will wait until the price drops. I n reality in Photoshop it actually beat a 2.66 667mhz 12gb of Ram with 3 10k drives with Raid 0. Now that is impressive for a laptop. In raw processing I lost time because of the reduction in cores but not by major amount but overall kicked the crap out of my old 2.4 2006 MPB. Can't have it all but this is good.

thanks guy - I've been checking in all day waiting for your post - it's a mbp 2.66 for me now.
 
I would certainly think the 2.66 would work since there cut from the same cookie cutter
 
Thx for the confirmation. With all the chatter about 8GB and on the 15"MBP, I changed my order on Saturday to a 2.66 from a 2.4 for this reason. Looking forward to seeing its status changed to shipping.
 
thanks for the info. as soon as i get my refund check im going to get one more stick of 4GB to achieve the full 8GB's. i hope that it works well for me as it has for you. editing in Pro Tools should be faster.
 
I guess the 2.66GHz and the 2.93GHz uses a different logic board to be able to use the 8gb of RAM.

I'm soooo glad I sold my 2.53GHz when I did! 8GB of RAM would be AWESOME running in dual channel mode on a notebook.
 
I thought photoshop is limited to 3gb of ram usage?

That is correct. BUT, if you have extra physical memory not being used, Photoshop will use that as a scratch disc after filling up its 3GB, before using your actual hard drive as a scratch disc. So it's basically an "extension" to fix the problem of being a 32-bit program.

also it means that you can have other programs running at the same time.

@Guy Mancuso:

i bought a 4GB kingston module the first time and i will just buy the same one again so they will be the same.
 
Not to say that I don't believe you but could you also post a screenshot of activity monitor using the ram?

Not a problem. Okay had a bunch of programs open but Capture One was processing files and Photoshop was running a action which took 2.5gb of Ram on it's own but if you can see the chart pretty well here I had 6:18 gb in use and 1.53 free. I could probably turn more stuff on but you get the idea I am already over 6gb being used

Impressive! OSX is very efficient in using as much RAM on apps as it can.

I was waiting for something like this. I've a pair of posts about the 2.93 model and 8GB, but nothing about the 2.66 one. I almost buy the 2.4 (good price for me), but since i read the macrumors a few days ago, I just stood by.

Thanks in advance.
 
BTW running all day at 1994 rpm and 54 . So it seems very stable and when i ramped up the fans went to about 5k which was pretty good than came right back down. No difference between any of the Ram configs.
 
Anyone read this regarding 6 and 8Gb in MBP (late 2008)??


NO, 8GB WON'T WORK
Just for fun we tried the 8GB configuration (2 x 4GB). Though the MacBook Pro will boot and Activity Monitor sees all 8GB, there are serious operational issues. For starters, if you use anything beyond 4GB of real memory, the MBP goes into "molasses" mode. And if you manage to quit out of the memory hungry app, the reported amount of real memory in use does not recede. At a certain point, our operation was so crippled that we had to push and hold the power button to force a shutdown.

Wonder has the OP experience any of this??

Hi, what blinking issue are you referring to? Is it the strobing/pulsating when computer is under load and hot?
 
How can you use 2 HDD in one laptop computer?
or does it have to HDD's in one compartment?
