Instead of HCI MemTest
HCI MemTest alternatives
HCI MemTest checks whether a computer can reliably store and retrieve data from memory, making it useful after buying a computer, installing RAM, or changing a system configuration such as overclocking. Its free Windows version can be unzipped and removed without changing files elsewhere or the registry. MemTest Pro adds control over thread count and RAM per thread, result summaries, command-line automation, error logs, and background testing. Deluxe adds a bootable 64-bit version that can access all RAM without loading an operating system, but requires CSM or legacy BIOS boot.

A different tool may fit better if you want broader hardware stress tests, more memory test algorithms, or a bootable option for other architectures. HCI MemTest's software cannot reliably pinpoint a failing physical memory chip, and its coverage guidance notes that intermittent errors may require testing to around 400%. Compare whether you need dedicated memory checks or a wider diagnostic purpose, the platforms and boot methods you can use, and whether automation or reporting matters. Also weigh HCI MemTest's one-time paid options against free alternatives or products whose pricing is on request.
