FurMark vs HCI MemTest

FurMark is a free Windows application for GPU stress testing and graphics benchmarking. It applies a sustained 3D workload to examine thermals, cooling headroom, power limits, and overclock stability. OpenGL and Vulkan rendering paths are available where supported. Benchmark choices include 1080p, 1440p, and 4K presets, along with timed passes. Artifact-oriented checks help identify visual problems such as sparkling or corrupted textures, which may point to heat, memory strain, or unstable tuning. For sensor context, FurMark recommends pairing runs with vendor tools or overlays, including GPU-Z and HWiNFO. Downloads come as an installer or a portable edition that runs from a folder or USB stick without installation. It is aimed at overclockers, PC gamers and builders, reviewers, benchmarkers, and support technicians. The FAQ points to a forum for troubleshooting. Tests should be supervised, temperatures watched, and unsafe runs stopped. The listed plan costs nothing for personal testing on Windows 10/11.

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.
