The RAMCHECK memory tester automatically detects the presence of the RAMCHECK SOJ EDO/FPM Adapter (p/n INN-8668-4). The memory tester also automatically determines the size and speed of the tested chip without need for special setup.

Standard DRAM testing is similar to the regular SIMM or DIMM test procedure.
