Default Mountain Lion is doodoo on 2GB RAM, what should I upgrade to?

So ML is really terrible on on 2GB RAM, should I go 4 or 8? Or 5, but that would be asynchronous and I think that would break dual channel? I'm happy with 4GB in Windows 8 but I'm not sure if ML handles differently (I was surprised how much heavier it feels than Windows). It's the last white macbook (c2d 2.4/320m).

If I did get a 4GB stick and went 5GB, would losing dual channel make anything significantly slower? This is for a med student, nothing heavy like programming or graphics work but she does multitask a lot.

Your MacBook officially only supports 4GB but people have been able to bump to 8GB. I'm not sure how well NVIDIA chipsets handle mis-matched DIMM sizes. Intel has Flex Mode which does have much of a performance hit anymore at all. I doubt you'd notice anything.

I would say, jump to 6GB (2+4GB) or 8GB.

As a word of advice, stay away from Kingston. Kingston + Mac has always been finicky (I've never tried any Kingston memory that was designated "Mac", though). I worked in a Authorized Apple Service Provider shop for 4 years and every non-Mac Kingston stick had issues. Stick to Crucial and some Corsair. We officially used Crucial for everything (reliability might not be the best, but it worked).

Throwing in an SSD helps a lot. I use Mushkin drives (120GB/240GB/480GB). They help the overall speed of the computer, including multi-tasking and virtual memory. The 240GB is on sale for $179:

Using 10.8 and 4GB pretty happily. I have an SSD though. I'd go to 8 if you can, just because it's cheap.

4 GB would be fine, but 8 GB is cheap.

2 x 4 GB Crucial can be had for under 40 bucks. You'd only save about $15 by going with 2 x 2 GB.

8 GB is $47.50 here
http://eshop.macsales.com/MyOWC/Upgrades.cfm?model=394

6 GB is $38 - why bother when it's only $10 for 2 GB more & maxed out?

SSD will help for sure, there are some bargains to be had.

ARE YOU NUTS???

8GB is so cheap it is hardly a mind thought. My October 2009 mini came alive with 8GB and I would never look back. I used the cheap g.skill off newegg and it tested and worked flawless right off the bat. Its been in for over 2 yrs and no issues.

An SSD like a samsung 830 series is also an awsome upgrade. It is tried and true.

I second the Samsung 830 + 8GB RAM upgrade. Can't go wrong there.

Using G.Skill here with no issues.
