This is a guide to upgrading the RAM (memory) on the MSI CR500 laptop. It is a loose translation of the [WWW]Japanese RAM upgrade wiki hosted at AtWiki.jp.

Before You Start

The CR500 comes equipped with 1GB of memory. This is enough for normal desktop usage, but if you plan to do memory-intensive things like video editing or playing 3D Games then this may limit what you can do with the machine. Luckily, you can upgrade the memory in the CR500 fairly easily. It has two memory slots, each of which takes SO-DIMM DDR2-800 (PC2-6400) memory. Each slot can hold memory cards up to 4GB, so if you take out the 1GB card that is pre-installed and put two 4GB cards in it is possible to have up to 8GB of memory.

Windows Vista and Windows 7 can only use about 3.25GB of RAM due to their 32 bit architecture, so if you plan to use either of them it is not worth installing more than 3GB of RAM (maybe 4GB if you really care about the remaining 0.25GB).

However, it is possible to create a [WWW]RAM Disk, which can use RAM that is not detected by the OS. This can greatly improve the speed of working with large files in applications such as Photoshop (compared with working from the hard disk), so you may want to consider upgrading to the full 8GB of RAM if this is something you will use.

Also, if you are using a 64-bit Operating System, the 3GB limit does not apply, and the full amount of RAM up to 8GB will be detected.

You can buy DDR2-800 RAM cards in sizes of 1GB, 2GB, and 4GB.

Upgrading the Memory

To upgrade the memory, you will need to take the back cover off your laptop. This will tear the warranty sticker and void your warranty. You also run the risk of damaging the tabs that hold the back cover in if you are not careful, or possibly damaging the RAM or the motherboard, so think carefully before deciding to upgrade the memory yourself. You may want to take it to a computer shop and pay them to do it instead.

Preperation

Make sure the environment you are working in is:

You will want to ground yourself to make sure you do not discharge static electricity into your laptop, as this may permanently damage it.

Step-by-step Instructions

  1. Remove the battery from your laptop. You don't want to get shocked whilst doing this.

  2. Unscrew the screws that are holding down the back cover of the laptop with a small Philips-head screwdriver. There are 4 screws in total.

  1. Starting from the side of the Microsoft sticker, slowly and carefully open the back cover.

This is what the back cover looks like halfway-open.

03.TabLocations.jpg

These are the rough locations of each tab. Use a small flathead screwdriver to get under the cover and gently push them open.

These are what the tabs look like from the inside.

This is what happens if you use too much force - the tab near the wireless adapter has been broken. (This is apparently the easiest one to break.)

The hard disk. It turns out it is made by Western Digital. (Mine was 320GB though.)

  1. Now it's time to put the new memory card in the memory slot.

  1. Finally, put the back cover on again, do up the 4 screws, and put the battery back in.

  2. Boot back into your Operating System of choice. The new RAM should be automatically detected.
