Developer 1usmus has released Hydra version 2.3B, a significant update to the tuning utility originally designed for Ryzen CPUs. This latest version introduces comprehensive VRAM overclocking and power limit controls specifically for Nvidia RTX 50-series GPUs.
The update enables a maximum memory offset of +3000MHz, allowing GDDR7 memory to reach speeds of 36 Gbps. Users can adjust static power limits up to 125% across all models, with 1usmus demonstrating these features on an Asus ROG Astral LC RTX 5090 OC card.
Hydra 2.3B adds direct XBAR offset control for interconnect tuning and second-generation Rail Offsets. With an unrestricted voltage frequency curve and experimental support for the RTX Pro 6000, the tool expands its existing Radeon and DRAM tuning suite.
