ANVIL is no longer just a DRAM stress test. It is becoming a new level of memory diagnostics inside HYDRA.
In this update, we have added something that has not existed before in consumer tools of this class: ANVIL can not only detect a memory error, but also provide diagnostic information about where the error appeared. HYDRA analyzes repeatability, the error pattern, its physical context, and helps determine whether it is a random failure, a weak tuning mode, a thermal issue, voltage behavior, or a sign of persistent DRAM instability.
ANVIL also now includes a game-simulation mode. During a DRAM test, HYDRA can create additional GPU load and simulate mouse and keyboard activity. This allows memory to be tested not in a sterile laboratory-like scenario, but closer to real use: the graphics card is working, the system is processing input, Windows is reacting to events, and DRAM is being stressed under more dynamic conditions. These scenarios can reveal instability that may never appear in a simple static memory-only test.
This is only the visible part of ANVIL's evolution. Over the past month, Anvil has gone through a large research phase: new test scenarios, a new runtime, improved telemetry, and a stronger foundation for future diagnostic features. There is already much more inside the code than what is visible in the final UI. Some features are still waiting for internal testing, so the release will expose only what we consider stable and safe enough for users.
At the same time, this update is much bigger than ANVIL alone. A lot of work was done across the entire HYDRA project: improving function safety, compatibility, API layers, driver interaction, monitoring, logging, and low-level reliability. Many of these changes are not flashy, but they make the whole platform more stable and ready for future features.
That is why this update is more like an iceberg than a simple changelog entry. Users will see new controls, better reports, and smarter diagnostics on the surface, but the larger part of the work is hidden underneath: research, compatibility work, safer low-level behavior, updated APIs, and internal systems that are already prepared for the next steps.
ANVIL is now smarter, safer, and much closer to answering not only “is there an error?”, but the much more important question: “why did it happen, and where should we look?”. And HYDRA itself has received a much stronger foundation for everything that comes next.

CHANGELOG:
New!!! HYDRA Health — a new page for quickly checking the state of HYDRA's core modules. It shows latency, error count and quality for low-level sensors, overlay, GPU/CPU monitoring and helper services.
Curve Shaper. Live read/apply mode has been added for supported Zen 5 systems. On other platforms HYDRA continues to use the compatible path.
Monitoring. Ryzen PMU monitoring has been substantially reworked to reduce dependence on the previous external telemetry path, improve stability and make the RTSS overlay more responsive.
DRAM SPD / PMIC / DIMM monitoring has been improved for DDR4 and DDR5, including more stable module reads and better display of temperatures, voltages and power.
Radeon / ADLX. ADLX has been updated to a newer base. Factory-default readback, reset-to-factory, ADLX lifecycle handling and RX-TUNER / GPU monitoring stability have been improved.
Low-level CPU access has been reworked for better compatibility with modern Windows security settings and fewer conflicts with drivers and protection mechanisms.
ANVIL. The built-in DRAM stress test has received a major update. A new native engine, extended Typical / Detailed / Custom presets, and flexible controls for duration, cycles, working set and stop conditions have been added.
ANVIL. New DDR-focused test scenarios have been added for modern Ryzen systems. Internal pattern details are not disclosed, but coverage is much wider than in the first alpha version.
ANVIL. Custom preset now lets you build your own test set, enable the required pattern groups and set repeat counts.
Added stop after a selected number of unique DRAM errors, sound alerts for new errors, improved progress and a more readable final report.
ANVIL. The diagnostic summary after each run is more useful: HYDRA now reports error repeatability, early localization hints, DIMM thermal state and DRAM voltage behavior without exposing sensitive internal maps.
ANVIL. Added helper game-like load and OS-trigger modes for scenarios where memory stability needs to be checked closer to a real gaming workload.
VANTA. The VRAM stress scheduler, Custom preset handling and error accounting have been improved. The test now separates errors between sub-patterns more accurately and does not lose fast error events.
VANTA. Added stop after a selected number of unique VRAM errors, sound alerts for new errors and a clearer final summary.
VANTA. Improved VRAM overheat control, GPU driver crash detection, warm-up phase and VRAM working-set calculation. Testing all available adapters is now more reliable.
RTSS. The PMU overlay now shows per-CCD metrics, L3 behavior and branch-miss information more reliably on supported Ryzen processors. The DRAM overlay has cleaner output for module temperature, power and voltage.
PresentMon and RTSS received better health tracking, more stable session cleanup and fewer chances to leave HYDRA in an incorrect state after a game, driver or test failure.
The ANVIL, VANTA, monitoring and main-window UI received many small fixes. A number of localization, formatting and stability issues have also been fixed.
Other minor fixes.
KNOWN ISSUES:
* False positive of antivirus (like always).
