Did you say laptop? I could've sworn you said desktop! That sounds like fun!

Also, the 8gb kit should work fine in the Santa Rosa+ based iMacs 🙂

They sure do:

GSkill is only $199 per 4gb stick! Get it while it's hot!!!

Wow.. talk about answer my wishes! 😀

Too bad I actually don't have extra money right now.. 🙁

Yeah, no kidding! I can't believe it's $199 per stick already!

I was planning on a 17" MBP eventually, but now I'm thinking about a Sager. The only drawback is that they don't have LED-backlit screens, which makes a HUGE difference for me. But I can get a Quad-core Sager with 8 gigs of RAM and 1.5TB of hard drive space, plus an 8800 or 9800 video card, for the same price as an upgraded 17" MBP. Granted it'd be heavier, but the build quality and performance are both much better. Decisions, decisions. Luckily I just paid for school so I'm broke for awhile, haha.

Oh wow.. well, I'm not buying a new laptop until next year, because I want my next one to have a Nehalem processor. But those Sager's are seriously amazing if they allow me to run OS X, with top of the line specs like that. Wow! 😀
 
Did the author actually prove he's using 8GB by looking at the Activity Monitor? I have an older MBP which can only use about 3GB of RAM, but if I look at the About This Mac screen, it says I have 4GB of RAM...yet I can only use about 3GB of the RAM installed.

I assume that this is different since other laptops with the same chipset support 8GB.

I was wondering this as well. The memory listed under "About this Mac" is not necessarily the same as what is actually available and being used by the OS.

This is for Santa Rosa or newer laptops...if your laptop only shows 3gb out of 4gb in Activity Monitor, then you have regular Core 2 Duo processor - it's too old to accept > 4gb.
 
So if I have the newest generation 2.4 C2D Pernyn and I take out my 2 gig stick and put in 8 gigs I can use all 8 gigs on the OS? Wouldn't that make it fly or would it not be worth the cost/speed gain. I do a lot of Crossover Games and Cider emulation so this could be killer for me.

Yes, you can add 8 gigs to your Penryn system.

8gb would certainly help the system move along, however, since it's a laptop you'll also want a 7200rpm drive or at least a speedy 5400rpm drive like the Samsung M6 500gb. Hard drive speed is very important in a laptop in order to get your system to feel snappy and responsive. I'd say do at least 4gb ram minimum combined with a fast drive. A 200gb 7200rpm, 320gb 7200rpm, or 500gb 5400rpm would all be good choices.

Personally, I run two Windows XP VMs 24/7 (2-cores + 3gb ram and 1-core + 2gb ram), so having 8 gigs in a laptop would be really killer! I could ditch the desktop and just have a crazy-awesome laptop to carry around with me, haha 🙂

yep running a single xp vm 24/7... i can vouch for the 7200 rpm hdd making a diff. i've never had more than 4 gigs of ram at any given time, so i really want to try this.

Do you actually see a performance difference or is this one of those upgrades so you can you have 8GB of ram in your laptop?

It really, really depends on the apps you use. That's what it all boils down to. I run Virtual Machines and do HD Video Editing, so I can NEVER have enough RAM. If all you do is use Firefox and iChat, then it's not really worth it.

I would have to say that the largest RAM-related performance boost I've seen was making the jump to 4 gigs. After that, you don't really feel it unless you're working with applications that require a lot of memory. But 4 gigs certainly helped things feel waaaaay smooth on all of my Mac machines.

Oh boy, it's amazing! It makes your computer work the way it's supposed to work - nice and smooth with zero slowdowns ever! For example, my current setup:

OS X = 300gb Raptor boot drive + 3gb RAM + 2 cores
XP VM1 = 250gb 7200rpm Seagate + 3gb RAM + 2 cores (Work VM)
XP VM2 = 250gb 7200rpm Seagate + 2gb RAM + 1 core (Play VM)

OS X is the primary boot system with both XP's running as Virtual Machines. Each has it's own drive to boot off of (well, they've both been on a single 500gb drive while I've been shuffling drives around this month, haha), plus plenty of RAM and a CPU core or two to work with. My VMs run faster than any of my real XP machines, lol! Since the VMs have their own drives, they're not reading/writing off my main drive, so there's no slowdown with that. Plus OS X has it's own fast boot drive and 3 gigs of RAM to work with, so it runs fabulously as well.

There are two things I'd like to see in the future for VMware - (1) bare metal support and (2) dual GPU or dual video card support. Having a VM image file is nice, but I'd really like to be able to tie a VM to bare metal like ESX does. I'm sure that would give some performance gains on reading/writing within the VM and also for transferring files to the Host OS. Also, I'd like to see them support full video cards. I'm pretty sure it's not possible with a single-gpu, single video card, but ATI now has a dual-GPU video card and maybe they could grab one of the GPU cores for full usage within a VM. Or, support dual video cards - the primary video card for OS X and the secondary for the VM (although that would require a second monitor). Either way, it'd sure be nice to be able to play games like Crysis or Half-Life 2 with a real video card without having to reboot!

Just depends on how much memory your games and apps require! What do you run in them?
 
Yea.. if you're running a VM, plus any kind of graphics or video editing software, you will want as much RAM as you can get!

Photoshop alone can take up to 3 GB of RAM, and then with 2 GB allotted to my VM... heh.. you can see why some people will need it. 🙂
