How to install a ram stick

Yes you can, at least to 1 Gb maybe possibly to 2 Gb.
There will be two memory slots in your laptop. To increase the RAM to 1 Gb install another 512 Mb RAM module in the empty 2nd memory slot. Make sure you use the same make and speed RAM as the one that is installed.
If you have two 256 Mb RAM modules installed in your laptop then you need to replace the two 256 Mb RAM modules with two 512 Mb RAM modules to get a total of 1 Gb RAM.

Here are the specifications of the Gateway 838GM: You will have to replace the existing memory with thesesettings only: The machine comes with: 512 MB = 256 MB (removable) + 256 MB PC3200DDR SDRAM DIMMs. Supports Dual Channel DDR Nowyou can only upgrade to 4.0 Gig total. I would recommend going to this link and order the correct memory foryour computer I use them quite a bit. http://www.memorystock.com/memory/Gateway838GM.html Rob

Hi this model sopport 2Gig Memory Ram.

Please check in to your Bios system maybe share memory Video or capacity is setting

You need the EXACT speed rated RAM.
Your support page states it needs.....
400-MHz DDR2 SDRAM
NOTE: Your computer supports only registered memory

Memory capacities
256-MB, 512-MB, 1-GB, 2-GB, and 4-GB ECC

256-MB, 512-MB, 1-GB, 2-GB, and 4-GB ECC modules to a max of 16GB

The Thinkpad is installed with 128 MB SDRAM is standard, and is expandable to 512 MB
There are two memory slots, to expand it to 512 Mb you need two 256 Mb RAM modules and throw away the 128 Mb RAM module, but if you don't throw away this module and you insert a 256 Mb RAM module in the 2nd memory slot then your total memory would be 384 Mb.

The original 2 sticks of 256 Mb of RAM gives you a total of 512
Mb of RAM. Two 512 Mb of RAM gives you a total of 1 Gb of RAM.
With two sticks of 512 Mb of RAM are you sure you got a total of 192 Mb of RAM, this is a lot less than the original RAM total of 512 Mb?
Should this be 1920 Mb of RAM?
If this 192 Mb is correct then the RAM modules are either not compatible with the laptop or if the RAM modules are not from the same manufacturer then they may not work together.

Most laptops have video cards that use part of the main RAM for video RAM, that is why the available RAM is less than the installed RAM modules. The amount of RAM the video card grabs depends upon the type of video card and in some cases the amount of video RAM can controlled in the BIOS setting.

This refers to the data width and chip configuration. 64*8 is an 8 chip 512MB module. (8 components @ 64MB each) 32*8 is an 8-chip 256MB module. (8 components @ 32MB each), etc.

Memory Installed 512 MB (2 x 256) Maximum allowed 4 GB* (4 x 1GB) requires the replacement of the installed 256 MB DIMMs

*Actual available memory may be less Speed supported PC3200 MB/sec Type 184 pin, DDR SDRAM DIMM slots Four Open DIMM slots Two

Thats the sticks you need

Good luck

Here's a link to the Data Sheet with the specifications to that Laptop in Adobe Reader format.

Looks like your Laptop came with either 256 or 512 MB of DDR SDRAM and it is upgradable to 2 GB of DDR SDRAM.

You can check to see exactly how much RAM your computer came with by going to Control Panel, double-click System and it should tell you how much RAM you currently have in the System Properties box.

The motherboard has 2 slots for RAM, you you could add a second 256 MB or a second 512 MB stick of RAM. Or if you wanted to upgrade to the 2GB of maximum RAM this computer handles, then you can take out the RAM chip(s) that is installed and install two 1G DDR SDRAM.

Your motherboard supports max of 2 GB PC 2100 RAM. Hope this helps.
