Chapter 1 : Introduction to Mac RAM

There is 2 types of RAM that you can install on your Mac.

(1) Apple Certified RAM
(2) Value RAM

Apple certified RAM are RAMs made specifically for Macs and users will most likely will not have trouble using them. Value RAM on the other hand, is memory commonly used for Windows laptops. However, since that transition of Macs to the Intel platform, many users have no problems using value RAM in their Macs.

The current iMac, Macbook and Macbook Pro use the same RAM. eg. You can use the same stick of RAM in the Macbook and the iMac. When purchasing RAM, make sure the RAM meets the following specifications...

PC2-5300
unbuffered
nonparity
200-pin
667 MHz DDR2 SDRAM


Chapter 2 : Installation of RAM

Macbook RAM Installation
Macbook Pro RAM Installation
Aluminium iMac RAM Installation
White iMac RAM Installation

Use the above links as a guide for RAM installation. Installing RAM is a relatively simple process. If you prefer, you can always bring your Mac to your Mac retailer to help you install the RAM. A small installation fee may be charged.

Chapter 3 : Additional Info

Where to buy RAM

List of Successful Value RAM Installed on Macs

Applications to Test RAM

Rember Download

You can use Rember to test if your RAM is working properly. However, Rember is known allow "bad RAM" to be tested as problem free.

Warranty
If you decide to self install RAM yourself, you WILL NOT void the warranty for you Mac. For instance, if your screen craps out on your in the future, you still CAN claim warranty. The only warranty that you will void is the original RAM of the Mac.

The newer Macs are designed so that RAM are user replaceable. However, before you proceed with your RAM upgrade, read your warranty just to be sure smile.gif

FAQ
QUOTE
Q: How do I know if I have enough RAM?
A: Take a look at your Activity Monitor. The Page Outs should be zero (or minimal). Page Out refers to the task being written to the hard disk (virtual memory) since there is insufficient RAM. High Page Outs would be most certainly accompanied by lags and slow response from your Mac.

QUOTE
Q: Is it true that I need to use RAM in pairs? (eg. 1GB and 1GB, and not 1GB and 512MB)
A: No, that is not true at all. You can use RAM in whichever pairing you prefer. However, you would benefit from slight faster performance when running in paired/dual channel mode. Most people prefer to run in pairs.

Here are some benchmark results

I'm using Corsair Value Select, no problems whatsoever since installed 2 months back. Another one you should consider is Crucial Ram.

I bought the first piece of 1GB Corsair Value Select at RM400 and the second piece at RM270.

From what I heard, Corsair Ram are tested piece by piece whereas Kingston tested randomly.

Thanks for the feedback

I've done some research on Corsair RAM at Newegg.com. Some Macbook users suffered from Random restarts after a few month's of usage. How long have you been using ur ram?

I had the first piece for about half a year, the second piece about 2 months. On the contrary to your research, there had been quite a number of feedbacks of people having problems with Kingston.

Btw the RSS Syndrome is NOT caused by Ram.

Good good. The RSS is heat related. The feedbacks said that after plugging in the original apple RAMs, the restart problems stopped.

Anyone else here to give me feedback on the value RAMs you use on a Macbook ?

I am using Mushkin Ram. I bought it for RM 180 each for 1 gig RAM at Startec Low Yat. I did a hardware test to check out the RAM and everything checked out ok. Been using for 2 weeks and I have no problem.

Hope this helps.

Thanks Sbanboy, it sure helps.

I've been doing some research and Crucial's 1GB stick of RAM it only USD$60. This is the RAM made for the current Macbooks. This is certainly a good deal.

Do you know where I can get em' other than ordering online since that international shipping is pricey. I checked the bulk buys, buy they only sell desktop performance RAMs.

I think you got the wrong idea. I don't sell RAM tongue.gif It's just a discussion on which RAM are compatible with Macbooks....

I've just purchase the 1GB of Corsair Value Select today for RM165.

So far so good biggrin.gif I figured i might as well get a tested RAM for only 10 bucks extra compared to the Kingston Value RAM.

Congrats.. and ENJOY!

But don't hope for your Mac to boot up faster, more ram actually slows down the boot up, BUT speeds up everything else...
