HCI MemTest vs Universal x86 Tuning Utility

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 the system configuration, including overclocking. The free MemTest download is Version 7.0 for Windows 9x, XP, 7, 8, 10, and 11; the product listing also names Linux. MemTest Pro adds controls for the number of threads and RAM assigned to each, plus summaries of results and total throughput. Pro also supports command-line automation, saves error logs to disk, and can test memory in the background while the computer is in use. Deluxe includes Pro and adds a 64-bit bootable CD or USB version that accesses all RAM without loading an operating system. That boot option requires CSM or legacy BIOS support. The maker recommends 100% coverage for most errors and around 400% for intermittent failures. The FAQ cautions that software cannot reliably identify a failing physical chip; testing modules one at a time may help isolate a faulty board. The free download can be unzipped into a folder and removed by deleting its contents. Free use is available; MemTest Pro costs $5, paid once, and Deluxe costs $14, paid once.

Universal x86 Tuning Utility (UXTU) is a free Windows utility for adjusting processor and GPU settings on x86 laptops and computers. It works best with Zen-based CPUs or APUs and Intel CPUs from the fourth generation onward. Users can select premade presets, save custom ones, or choose Adaptive Mode, which monitors processor temperatures as it adjusts power limits. The app also has Game Library, System Info, and Automations sections. AutoOC monitors CPU and memory instability signals and changes Curve Optimiser offsets for Zen-based CPUs and APUs. Version 26.3.0 added an in-game overlay, preset backup and import, tray shortcuts, Windows power-plan options, Intel presets, and experimental Zen6 support; games with anti-cheat may not always work with the overlay. Windows installer and portable downloads are available. The latest stable release requires .NET 10 64-bit, PawnIO Driver, and Microsoft Visual C++ Redistributable. UXTU is free under GPL-3.0. The project describes itself as a work in progress and warns that misuse may cause instability or malfunction.
