The record

Purpose: MemTest runs under Windows and checks whether a computer can reliably store and retrieve data from memory.
Use cases: The maker recommends testing after buying a computer, installing RAM, or changing system configuration such as overclocking.
Version: The site lists MemTest Version 7.0 for Windows 9x, XP, 7, 8, 10, and 11.
Pro controls: MemTest Pro has an advanced interface with control over thread count and RAM per thread, and summarizes results across threads and total test throughput.
Automation: Pro offers full command-line control for automated or periodic testing.
Error logs: Pro logs errors to disk so users can send an error report to the RAM seller or review what happened after a crash or shutdown.
Background testing: Pro includes a “nice” mode for testing RAM in the background during normal computer use.
Deluxe boot mode: Deluxe adds a 64-bit version that runs from bootable CD or USB without loading an operating system and can directly access all RAM.
Compatibility limit: The Deluxe bootable version requires a PC that supports CSM or legacy BIOS boot.
Coverage guidance: The maker says 100% coverage should catch all errors except intermittent failures, for which it recommends testing to around 400%.
Diagnostic limit: The FAQ says software cannot reliably pinpoint the physical memory chip that is failing; it suggests testing modules one at a time to isolate a faulty board.
Installation and removal: The free download can be unzipped into a folder, does not modify files elsewhere or the registry, and can be removed by deleting its folder contents.
Support: The maker provides an online manual and FAQ for help using MemTest.
Maker background: HCI Design says it has had an online presence since 1998 and describes its product line as RAM testing tools and Windows utilities for power users.
