8GB on the new UMBP 2.93GHZ

Hey guys.
Just wanted to confirm that 8GB memory on the 15" UMBP 2.93 GHz is really working and works like charm. I installed OWC modules and works just fine up until now. Even though they didnt say specifically for 15", but it works!!

My guess is that 2.66 15" UMBP can also fit 8GB. Haven't tried it though.

Hope this clears answers about 8GB on the 15" UMBP

What happens when you access over 6GB?

What do you mean access over 6GB? I'm doing OK here in my MBP.. The activity monitor shows full 8GB fully detected.

All MacBook Pros can detect 8GB. The problem is when they access over 6GB (start using more than 6GB) they become unstable.

Not in my MacBook Pro. I've been running on 8GB for almost a day non stop now. This thing works really nice. I ran VMWare with Vista simultaneously and rendering some movies with iMovie.

The activity monitor shows 8GB to me and its definitely stable.

B&O isn't questioning that Activity Monitor SHOWS 8gb... The question is rather.. What happens when you are USING more than 6GB or RAM... When you look at the Activity Monitor, and the total of "Active" and "Wired" is GREATER than 6GB... This is when the MBP begins to have problems... It has no problems "reading" 8GB whatsoever... It's problem is when it attempts to USE 8GB.

Ride is spot on, they all can read 8GB but using it is another story.

I got no problem or whatsoever right up until now. At least no issue my MBP becoming unstable etc. Works great.

But the questions is, have you actually used more than 6GB of RAM? The system will be fine with 8GB but as soon as you uses over 6GB the system starts to run into problems.

In fact, as I am writing this, my used memory in activity monitor shows 6.87GB used and 1.11GB free. I've been using my macbook pro for over 2 hrs and no problems or whatsoever. No crash or kernel panics. It's been great. By far, 8GB shows no problem to me. Everything works great.

@macfrik I would absolutely love it if you could post a screenshot with more than 6 gigs being used. Thanks in advance.

Sure. I'll do that this evening when it reaches more than 6GB.

Here it is!

8 gb cool.

Very cool. By the way he really only needed to go above 4gb to test if the chip works. In previous 8gb Macbook Tests it went crazy after 4gbs. ...

will an upgrade to 8GB be possible on my 2.53Ghz?

Just need to find out will the 8GB upgrade work with a 2.53Ghz MBP too? without software firmware upgrades etc?ie straight from the ram box so to speak?
