- A Memory Testing Environment for MMX PCs -
Current version: 2.0 - Page last updated: 01 Jun 2001


MemMXtest is a computer program for "IBM-compatible" PCs, that checks the computer's main memory for faults and defects. (Note however, that no program can be guaranteed to detect all faults, due to their very nature.) This program is aimed specifically at testing SDRAM memory modules (`DIMMs'), and uses MMX instructions to read/write all 64 databits provided by these modules at once. MemMXtest incorporates many well-known `march' tests, as well as several pseudo-random tests. The vital parts of each test use manually optimized machine code for maximal speed.

This program originates from a study project at the department of Information Technology and Systems (sub-department Electrical Engineering) of the Delft University of Technology.
