NVIDIA Blackwell GPU Surpasses 4 GHz with Extreme Overclocking
In a remarkable achievement for GPU overclocking, Team OGS has pushed NVIDIA's latest "Blackwell" GPU architecture past the 4 GHz barrier using advanced cooling techniques. Leveraging the GALAX GeForce RTX 5090D Hall of Fame OC Lab Edition graphics card, the team achieved a core clock speed of 4,002 MHz on the GB202 GPU, while the memory operated at 1,860 MHz.
The milestone was officially validated through a HWBOT submission, utilizing the GPUPI v3.3 32B benchmark. During the test, the GPU maintained the 4 GHz frequency for 35.377 seconds, focusing on compute-intensive workloads rather than 3D rendering tasks. This approach allowed the GPU to reach higher clock speeds than typically possible during gaming or other graphics-heavy applications.
Technical Setup and Overclocking Methodology
Achieving this record-breaking frequency required a specialized setup. The team employed liquid nitrogen (LN2) cooling to keep the GPU temperatures under control during the extreme overclock. An external clock board from Elmor, set at 28.7 MHz, was used to fine-tune the clock speeds with precision.
The supporting hardware included an Intel Core i9-14900KF processor running at 6.0 GHz, installed on an ASUS ROG Maximus Z790 Apex Encore motherboard. The system was equipped with 32 GB of memory and powered by a robust 3,000 W Corsair WS3000 power supply, ensuring stability throughout the overclocking session.
This accomplishment highlights the potential of NVIDIA's Blackwell architecture when paired with high-end components and expert overclocking techniques. The demonstration, captured on video, showcases the GPU operating at the unprecedented 4 GHz mark, setting a new standard for enthusiasts and professionals in the overclocking community.
