Team OGS breaks 4GHz barrier with Galax RTX 5090D HOF

Team OGS has submitted a new HWBOT entry showcasing a Galax GeForce RTX 5090D HOF OC Lab Edition running at 4002MHz. This represents the first validated 4GHz core frequency milestone for an Nvidia Blackwell graphics card under extreme overclocking conditions.

Validation (via Wccftech) was achieved through the GPUPI v3.3 32B benchmark, with the run completing in 35 seconds and 377 milliseconds. According to the HWBOT submission, the graphics card used a GB202-based GPU core paired with 1860MHz memory clocks. This lightweight compute workload does not tax the GPU as much as modern 3D titles, allowing for extreme clocks.

The overclocking setup relied on an Elmor External Clock Board set to 28.7MHz, overriding the standard internal reference clock. Liquid nitrogen cooling managed the thermal load, utilising a Bitspower Strata LN2 GPU Pot and Thermal Grizzly Kryonaut Extreme thermal paste. Other hardware consisted of an Intel Core i9-14900KF running at 6.0GHz, an Asus ROG Maximus Z790 Apex Encore motherboard, 32GB of Corsair Vengeance DDR5 memory, and a Corsair WS3000 power supply.

This submission specifically utilised the original Galax RTX 5090D HOF OC Lab Edition variant. The model maintains the original layout, distinguishing it from the newer V2 version, which has a cut-down 24GB configuration and a narrower 384-bit bus.

KitGuru says: Do you think overclockers will be able to push the Blackwell architecture much further than this?
