Stabilty is wonderfull, no craches everyting is fast.
I'm quite positive that 8 gb will work too. Of course it needs a test first.

Refer to this post. We have done many tests, 8GB fails in terms of OS using the full 8GB properly.

Feel So Stupid
I love how all these people for the past year said that 4 GB was the max. I bought 2 4GB SO_DIMM chips from newegg and just installed last night. Leopard will only read 6 GB, but thats 6GB! not 4.
And logic is running 36 tracks better than ever.
thanks newegg. 299.00 for 8 GB is smashing.
PS. has everyone seen the benchmarks on the new MBP's? Looks like im staying with mine for a while longer until the new processors are implemented. There is almost no proformance difference between the mbp 4,1 and the new "brick", in some cases the mbp 4,1 still out preformed.

That's so cool.
Well done.
I only wish the DDR1 will have a 2GB module. There are only one slot in my poor 12 inch powebook.

8GB RAM in Macbook Pro
You can install 8GB of DDR2 in a 2008 (Non-Unibody) Macbook Pro. I've done it and I've also done 6GB. 8GB, although possible and your system will recognize it, is rather unstable. From my experience, 6GB is pretty solid. I can't honestly say it made a difference though. I used two 4GB Samsung modules and I found my system lagged, stalled and beach balled on just about every application. When I went back to 6GB, those problems stopped. Running on both configurations, I've never come close to hitting the 4GB usage level and I really don't see any advantage to exceeding 4GB.

Those of of use who run a lot of VM's can use the RAM. I have 5 VM's that I use for various purposes at work, and being able to run multiple VM's in parallel is very nice.
That being said, the 8gb does not work in the 4,1. As you get to 4gb actually used, then the CPU goes into massive system time and the system is very unstable.
I suspect that there is an issue in the hardware or firmware that is causing the memory to not be properly accessed. 6GB, however, runs fine.
I've tried a variety of tweaks and there's plenty of information from others who have tried it as well. Google it. ;-p
So, it's 6gb, and I'll stick with the 4,1 until DDR3 drops to a reasonable price. The new MBP's (certain models!) will run with 8gb RAM.

I just received a 4 gb DDR2 module from G.Skill and this works fine in aMacbook pro 2.4 Core2 Duo.
I'm thinking about ordering a second one to make up for 8 in total!
...isn't it best to have the larger module in the primary slot
I have 8gb (2x4gb crucial) in my non unibody, (early 08) 17" mbp (2.6).
So far working fine, no hicups, beach balls, etc. Running 10.5.7
Only installed for about a day or so, but Ive used FCP, photoshop, and
other regular daily use software without an issue.
Going to give it a week of normal use and sell my 2gb sticks if it continues to work this good.
Rather then cross post new info, here is another link about the 8gb ram in older mb pros.
