Versions:
PYPrime is an open-source memory benchmark utility developed by Monabuntur that uses the Python runtime to measure RAM bandwidth and latency on Windows workstations. Written entirely in Python, the tool focuses on pure memory performance without stressing the CPU or storage subsystems, making it useful for validating overclocked DDR4/DDR5 profiles, comparing dual-channel versus single-channel configurations, or quickly checking whether firmware updates have altered memory timings. The program launches a configurable thread count, allocates a user-defined block of system RAM, and then performs sequential and random read/write passes while recording throughput in megabytes per second and access latency in nanoseconds; results are displayed in a minimalist console interface and can be logged to CSV for later analysis. Because the source code is published under a permissive license, reviewers can inspect the algorithms, compile custom builds, or embed the benchmark into larger automation scripts. Version 2.2.211023, released on 23 October 2021, represents the first and only public milestone so far, offering both 32-bit and 64-bit executables that require no installation and weigh less than 5 MB. Enthusiasts typically pair PYPrime with synthetic CPU or storage tests to create a quick, lightweight validation suite for new hardware, while system builders add it to USB toolkits for on-site diagnostics. The package is categorized under Benchmark Software on get.nero.com, where it is available for free, with downloads delivered through trusted Windows package sources such as winget, always serving the latest version and supporting batch installation alongside other applications.
