The product is an 8MB upgrade kit for EDO non-parity SIMM memory modules, manufactured by NPNX. Each module has a capacity of 8MB and a form factor of SIMM, with 72 pins. It is designed to expand the memory capacity of computers that use non-parity SIMM modules, providing a reliable and compatible upgrade solution for older systems. The product is ideal for users looking to enhance the performance and efficiency of their computers by increasing the available memory size.
EDO 2x32 NPX refers to a type of memory module, specifically EDO (Extended Data Out) RAM in a 72-pin SIMM format with a module configuration of 2x32, where each SIMM contains two sets of 32-bit data paths, totaling 8 MB per module. NPX typically stands for "Non-Parity," meaning the modules do not have parity checking for error correction.KEY USAGE AND COMPATIBILITY:
- EDO RAM was popular in the mid-1990s and is commonly found in 486, early Pentium, and some workstation/server (NPX/NPN) modules do not support parity checking, so are not suitable for systems requiring parity RAM.
- Module timing (e.g., 60ns) and voltage (typically 5V) must be checked for compatibility with your motherboard.
If you are considering using EDO RAM in a system designed for FPM (Fast Page Mode) memory, note that some boards may accept EDO as a drop-in replacement, while others may require modifications due to subtle differences in signal timing.
