Summary

HCI MemTest checks whether a computer can store and retrieve data from memory reliably. Its maker recommends running it after buying a computer, installing RAM, or changing a system setting such as overclocking. The free Windows download is Version 7.0, listed for Windows 9x, XP, 7, 8, 10, and 11; the product listing also names Linux. The Pro edition adds controls for thread count and RAM allocation per thread, result summaries, command-line automation, disk-based error logs, and a mode for testing while using the computer. Deluxe includes Pro and adds a 64-bit bootable CD or USB version that can access all RAM without loading an operating system. That boot option requires CSM or legacy BIOS support. The maker says 100% coverage should detect errors other than intermittent failures, for which it suggests testing to about 400%. MemTest cannot reliably identify the failing physical chip; testing memory modules individually can help isolate a faulty board. The free download can be unpacked into a folder and removed by deleting that folder.

Who it is for

It suits Windows users checking RAM after hardware or system changes, and those who want automated or background testing in Pro. Deluxe may suit users who need boot-time access to RAM and have CSM or legacy BIOS support.

What is good

Free Windows plan is available.
Pro supports command-line automated testing.
Pro records errors to disk.
Deluxe can access all RAM at boot.
Free download can be removed by deleting its folder.

What to know first

Deluxe boot mode requires CSM or legacy BIOS.
MemTest cannot reliably pinpoint the failing physical chip.
Pro costs 5.00 USD per once.
Deluxe costs 14.00 USD per once.

Verdict

HCI MemTest offers a free way to check memory reliability, with Pro adding automation and logging and Deluxe adding bootable testing. Keep in mind the boot mode has a BIOS compatibility requirement, and the software cannot identify a failing chip reliably.
