How do you know you're getting exactly the right memory for you? As part of Micron, Crucial is the only memory upgrade supplier that's part of a major DRAM manufacturer. We work closely with major computer and motherboard manufacturers to make reliable, high-performing, compatible memory.
From stringent quality testing, which begins at the chip level at Micron, to ongoing compatibility testing in the Crucial Compatibility Lab, we take testing one step further to make sure you end up with exactly the right memory for you.

|Now You Know What Works. ... Follow these 3 steps to get the upgrade that's best for you.|
Start by determining how many megabytes (MB) your computer can hold.
The Crucial Memory Advisor has already done this step for you! The maximum memory your Packard Bell Axcel 472 can support is 128MB.
Determine how many memory modules you can install.
The amount of total memory slots in your Packard Bell Axcel 472 is 4 (2 banks of 2).
The first number refers to the total number of slots your system has for memory modules. For example, if the first number is "2," a maximum of two modules can be installed. The numbers in parentheses refer to the number of banks in your system. If you have banks of 1, you can purchase and install one module at a time. If you have banks of 2, you need to purchase and install two modules at a time, and if you have banks of 4, you need to purchase and install four modules at a time.
How many modules are in your system now?
Now that you know how many memory slots your computer has, determine how many modules are currently installed in your computer. You can either: a) open your computer's case, identify the memory slots and count the number of empty slots or: b) use the Belarc Advisor to automatically detect your system's configuration information.
How many modules can you add to your computer?
You can add as many memory modules as your computer has empty memory slots. Just make sure you don't exceed the maximum amount of megabytes your computer can handle as determined in Step 1.
Putting it all together. Based on the number of memory slots and the number of megabytes your computer can hold, determine which of the compatible upgrades will best meet your computing needs and budget.Let's say you've taken our advice and you've decided you want your computer to have a total of 512MB of memory.

Installed in pairs of modules.
When you buy direct from Crucial, you're buying top-quality products with expert technical support and proven customer service. Here are a few reasons why you should choose Crucial above the competition.
A single inline memory module (SIMM) consists of a number of memory components (usually black) that are attached to a printed circuit board (usually green). The gold or tin pins on the bottom of the SIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a SIMM are connected.
72-pin SIMMs are commonly found in older desktop computers, such as the 486 and early Pentium® models. 72-pin SIMMs are available in FPM or EDO. When upgrading, be sure to match the memory technology that is already in your system. (Information about which memory technology your system uses is included in the Crucial Memory Advisor™ tool.)
The number of black components on a 72-pin SIMM can vary. 72-pin SIMMs are approximately 4.25 inches long and 1 inch high, though the heights can vary. They have one notch on the bottom left and one notch in the center of the module.
Number of Slots: X (X banks of X)The first number (the first X) tells you the total number places your system has for memory modules. For instance, if the Memory Selector says you have four slots, a maximum of four modules can be plugged into your motherboard at once. Pretty straightforward.
So What Are "Banks"?
The vast majority of systems allow you to install memory modules one at a time. However, some systems require you to install modules in sets or "banks" — most commonly banks of two or four. For example, if you have four total slots, you could have 4 banks of 1, 2 banks of 2, or 1 bank of 4.
If you have banks of 1, you can purchase and install one module at a time. If you have banks of 2, you need to purchase and install two modules at a time, and if you have banks of 4, you need to purchase and install four modules at a time.
To help you order and install your memory correctly, the Memory Selector automatically sets the quantity for your purchase to the lowest appropriate number. So if your system has banks of 2, the quantity will be pre-set to 2.
Whether or not your memory is installed in banks, your total system memory is always the total memory from all of your modules added together. That means that if you want to add 64MB to your system and your memory is installed in banks of 2, you will need to buy two 32MB modules.
It is usually to your advantage to purchase the highest density modules that you can afford, especially if you don't have very many open slots left. For example, if you have four open slots, you could buy four 32MB modules for a total upgrade of 128MB. However, if you wanted to upgrade again in the future, you would have to remove one of your modules and the money you spent for that module would be wasted. If instead you install just one 128MB module, you will still have three open slots left to fill if you want to upgrade again later on.
