Get RAM upgrades for old systems…and save money

On average, people replace their computers every four years. But why? The Memory Experts at Crucial think you should be reluctant to part with your trusted system. You might be surprised how easy it is to improve the performance of an older system – giving it new life and saving you money to boot—with a simple RAM upgrade.

Crucial defines “legacy memory”

as any modules compatible with a system five years or older. While RAM technology has evolved and changed, we still carry the older technology that will give those systems a boost and make them good as new.

Some of our notable legacy memory?

We carry a 32MB EDO 72pin SIMM – compatible with 1,389 systems according to the Crucial System Scanner. The earliest SDR available at is a 256MB PC133 168-pin DIMM (compatible with 4,580 systems) and a 256MB PC133 144pin SODIMM (which works with 1,220 systems). And for even broader array of systems, we carry DDR (PC2700 and PC3200) modules.

Memory types include EDO, SDRAM, DDR, DDR, and DDR3. To learn more about those specific memory types, read our article or watch this video. The important thing to understand is memory types are not interchangeable. If your system takes DDR memory, you need a DDR upgrade – the newer DDR2 or DDR3 simply isn&rsquot compatible.

So what will work with your older systems?

Use the Crucial System Scanner or the Crucial Memory Selector to find out what kind of memory type your system uses. Our upgrades are guaranteed to be compatible when you use one of these tools. And keep in mind that installing your own memory is easy. Check out our installation guides to learn more.

It's worth it

Legacy memory costs a little more than memory for newer systems. Why?
