Handheld Companion vs HCI MemTest

Handheld Companion is a free, open-source Windows app for handheld gaming PCs, with touch-optimized controls and device settings. It maps controller inputs to keyboard, mouse, joystick, trigger, or virtual controller actions, including Xbox 360 and DualShock 4 output. Universal Motion Control translates supported motion sensor data for aiming, camera control, racing, and emulators. QuickTools adjusts TDP, frame limits, refresh rate, resolution, brightness, volume, and power mode. The app can detect the active game and apply saved controller, motion, graphics, and power preferences automatically. Listed device families include ROG Ally, Steam Deck, Legion Go, MSI Claw, AYANEO, and GPD Win. Steam Deck support applies to Windows 10 or 11 installations; this is not a SteamOS application. The free public release costs nothing for Windows 10/11 on x86 and x64. Installation requires administrator rights to deploy services and drivers.

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.
