Try it yourself

You've taken the first step - getting under the hood. The next step is to try a simple upgrade on your own.

The simplest one is a memory upgrade.

1st - what kind of memory do you have and how much can you install?

I use Crucial (www.crucial.com) for my memory information.

You'll need to know your computer's make, product line, and model number.

Follow three easy steps:

  1. Select the manufacturer        (Gateway)                           Look here                    

  2. Select your product line        (4xxxx Series Desktop)        Now here

  3. Select your specific model    (420GR)                              Once more

Now you've reached the page with all of the "crucial" (HA!) information.    Last one

Some of the information provided includes:

Once you've purchased compatible memory modules (chips), you must install them.  CLICK ME

Q: What memory goes into my computer, and will a faster speed be backward-compatible?

A: DDR memory with support for DDR PC3200,DDR PC4000 speeds.

Because DDR memory is backward-compatible, you can safely upgrade your system with any of the guaranteed-compatible DDR speeds listed below, even if your manual calls for PC1600 or PC2100 speeds.

Q: How much memory can my computer handle?

Q: Do I have to install matching pairs?

Q: Does my computer support dual-channel memory?

Q: Does my computer support ECC memory?

Q: Will my system recognize the maximum upgrade?
