Please do your own research for your specific computer. There are many guides available on the internet. 

All memory offered here have been pulled out of one of the above working computers.

Memory Speed
Memory speed is measured in ns, the lower the number the faster the memory module will be.  All memory modules have been checked to verify speed, the speed of the chip may be different that what is labeled on the chip.   Some manufacturers labeled their chips with a faster speed than what the actual chip performs at.  For example, if you purchase a 100ns memory module and it has a manufacturer’s label that says 70ns, the actual speed of the chip will be 100ns. Some computer system have specific speed requirements and you should research if the memory for your computer system must perform at a certain speed or better and purchase accordingly. 

Memory Type
There are two types of memory available FPM (Fast Page Mode) and EDO (Extended Data Out).  FPM was the standard memory type that computers used in the early to mid 90s.  EDO started being produced in the mid 90s and was used in most systems until the late 90s.  That being said, you should do your research about what the system that you are purchasing memory for uses and purchase accordingly.  

Matching pairs are available and will be provided when you order 2 or more modules.
