RTX 5090

Changing the MSVDD voltage with melonVolt directly adjusts the RTX 5090 crossbar frequency, automatically increasing or decreasing it as the voltage is raised or lowered. User reports show gains of over 100 MHz on some cards, with examples ranging from a 90 MHz increase (2670 MHz to 2760 MHz) up to a 142 MHz increase (2625 MHz to 2767 MHz). The tool manipulates a voltage NVIDIA does not expose and there is no officially known safe MSVDD voltage. Answered

No. For now melonVolt cannot be used on lower-tier RTX 50 series GPUs because its creator Fmab has only released versions for the RTX 5090 and RTX 5080. The article notes the RTX 5080 build arrived just yesterday, suggesting Fmab might create support for more models in the future. Answered

Zotac replaced the RTX 4090 with an RTX 5090 because they could not source RTX 4090 replacement stock and their warranty policy allows out-of-stock products to be replaced with hardware offering equal or greater performance. The upgrade followed Zotac's policy of substituting unavailable products with comparable or superior models. Answered

The replacement RTX 5090 came with only a 30-day warranty rather than Zotac's standard three-year coverage. This matches Zotac's policy that replacement units retain the original product's remaining warranty period. Answered
