Last month, we introduced one of the biggest evolutions in OCCT’s history: a completely redesigned and fully modular Memory Test.
Today, we’re excited to officially release OCCT v17, bringing together the new Memory Test system alongside a new launcher for OCCT and major optimizations and quality-of-life improvements across the entire application.
This release also comes with new presets for the memory test, including a community-made preset by Stephen Shanks, with even more to come in future releases.
OCCT v17 introduces a full redesign of the Memory Test, rebuilt entirely from scratch around a highly modular architecture.
Currently, the new system includes 16 individual testing blocks that can be freely combined to create highly customized memory stress tests. This makes the new OCCT Memory Test one of the most flexible and customizable memory validation solutions available.
Whether you're validating system stability, investigating intermittent memory issues, or creating specialized test scenarios, the new framework gives you complete control over how memory is stressed and analyzed.
Optimizations and Quality-of-Life Improvements
Alongside the new Memory Test, OCCT v17 delivers major improvements to performance, reliability, and overall usability.
FASTER STARTUP TIME - A brand-new launcher improves startup times by approximately 10% to 30%.
LOWER MEMORY USAGE - Overall memory consumption has been reduced by approximately 15% to 30%, with monitoring data now written directly to disk for improved efficiency during long test sessions.
IMPROVED RELIABILITY - Better support for portable installations, a reworked auto-update system, and enhanced crash recovery make OCCT more stable and easier to troubleshoot than ever.
Download OCCT v17One of the goals behind the new Memory Test architecture is to enable the community to create and share powerful testing scenarios.
The stable version of V17 launches with 6 presets, including one community-made preset, AM5 Margin Probe by 'srshanks'.
Over the coming months, we’ll continue working internally and with the community to identify useful presets that can be integrated directly into OCCT, making advanced testing methods accessible to everyone.
If you have created a particularly effective memory testing configuration, we encourage you to share it with other users through our Discord server and community channels.
