Does anyone know what type of RAM this is? It is in an old computer of a friends and we want to upgrade that computer a bit.

The ram has 72 pins and is kinda old now. The picture isn't very good, I know. That particular stick is 8mb

72 pin EDO SIMM, the memory must be added in matched pairs.

well you can, they have to match in capacity at the very least. i can't remember the specifics, it's been quite some time since i've worked with this stuff.

Actually they (they being generally of ram, these may be too old) only need to somewhat match for dual channel. You could randomly mix a bunch of ram and get lucky(I have a friend that did), but if you want dual channel you need to have close or the same specs (theoretically company doesn't matter, but be prepared for some blue screens if you do mix ram).

trust me on this one mate

dual channel was only introduced with DDR memory, or as i'm not too familiar with the platform RD-RAM. so the earliest dual channel was with K7 and P4 technology. this memory fits in somewhere around late 486 to late Pentium. 168 pin SD-RAM DIMMs were being introduced by the end of the original Pentiums. SIMMs are added in matched pairs, each pair making a single "bank" of memory.

Quote:
Note: EDO memory must be installed in pairs. Fast page must be installed in pairs in Pentium class computers. By "in pairs" I mean 2 of the exact same type of SIMM must be installed. For example, if you want to upgrade by adding 32MB of memory you must put in 2 16MB SIMMS.
