GSmartControl vs MemTest64

GSmartControl is a graphical interface for smartctl, used to inspect drive SMART data and run tests. It displays drive identity, capabilities, attributes and device statistics, and automatically highlights anomalies. Users can enable or disable SMART and adjust global or per-drive smartctl options. Saved smartctl output can be opened as a read-only virtual device. The software supports ATA drives, including SATA and PATA, and NVMe drives, plus some devices behind USB bridges and selected RAID controllers. SCSI and SAS drives are not supported, though some information about them may appear. GSmartControl is free software under the GNU General Public License version 3. Downloads include Linux packages, Windows installers and portable archives, FreeBSD ports, macOS packages and source code. smartmontools is a runtime requirement, but official Windows packages include the required software. Useful operations require root or Administrator privileges because operating systems restrict direct hardware access. Supported systems listed include Linux, Windows, FreeBSD, NetBSD, OpenBSD, DragonFlyBSD, macOS and Solaris; QNX support is described as untested.

MemTest64 is a free, standalone Windows utility for checking system memory for hardware-level problems. It runs inside Windows with a graphical interface, loading physical memory with test patterns and applying detection algorithms that identify errors automatically. You choose how much memory to test, which can limit the effect on other work. The utility runs without a reboot or DOS mode, does not require administrator privileges, needs no installation, and makes no registry changes. Listed processor support includes modern Intel Core and AMD Ryzen systems. Supported systems are 64-bit Windows XP, Vista, 7, 8, 10, and 11. TechPowerUp describes it as useful to overclockers adjusting memory timings and DRAM speeds. The utilities listing identifies version 1.0, dated April 20, 2017, and the product page links to a support forum.
