Karhu RAM Test

What Karhu RAM Test is

Karhu RAM Test is a paid Windows memory stress-testing tool intended to detect faulty hardware and instability from overclocking. The maker lists support for up to 8 TB of RAM and 64 threads, with optimized code paths for AVX- and AVX2-capable processors. It can run from a USB flash drive, and its FAQ describes an algorithm that differs from simple bit-pattern testing. Version 2.0 changes listed by the maker include customizable algorithms, latency and bandwidth benchmarks, test history, and HWiNFO sensor monitoring; HWiNFO integration is Windows-only. There is no free version. The Personal license covers non-commercial use on up to five computers and is billed as a one-time license, while commercial use requires the Commercial license and contacting sales for pricing. Linux version 2.x is marked TBA with no download file listed. Planned items include error tracing, remote management and notifications, a command-line interface, and XMP 3.0/EXPO profile rewriting. Karhu Software oy is based in Tampere, Finland.
