reusing a memory card in another pc possible?

Specs: Pentium III 550 Mgz, 128
I have a Compaq deskpro that only has 128mb and have an old card/stick that is 256 mb. Would like to know if I can just put that 256 in DIMM slot 2 and expand my memory? It is a 100mhz card like the one thats already in it. only differnce is pc calls for 16meg x64 and this old card is 16meg x 72...compatible?? Thankyou

No, you can't use that memory. It is error correction type (72) and your other stick isn't. Plus, most consumer boards can't use error correction RAM anyway.

So could I take out the 128 and put in the 256 to at least get 256 Mb?
Maybe this card came out of an old Freedon station ??

As I stated, your board must be capable of using error corrrection RAM. Most consumer boards can't.

Go to and run their online scan tool. It will tell you all the different memory modules your board can run. Unless your compaq was sold as a business class computer it isn't going to use that type of RAM.

A 256 meg stick is going to be 32meg x 64 (or 32meg x 72 for ECC). So unless I'm misreading your initial posting or you've made a typo, both sticks are 128.

Also, I think you can use both sticks in the same system as long as ECC is disabled in cmos/bios setup. At least that's the way it was with the parity check that some older SIMMs used.
