A new tool, melonVolt, has emerged, allowing users to overclock the crossbar frequency of RTX 5090 GPUs, resulting in significant performance gains. This tool, developed by Fmab, enables users to adjust the MSVDD voltage, a setting previously inaccessible in official overclocking tools. User reports from overclock.net forums indicate impressive gains, with some GPUs achieving clock speed increases of up to 142MHz. However, the tool's effectiveness is still under scrutiny due to the limited benchmarking information available. Despite the risks, including potential damage to the GPU, the tool has sparked excitement among enthusiasts, who are eager to explore its capabilities further.
