Team OGS pushed the NVIDIA GeForce RTX 5090D to 4,002 MHz core clock speeds with liquid nitrogen cooling, marking the first time a Blackwell GPU breached 4 GHz. This feat, achieved on a GALAX Hall of Fame OC Lab Edition GPU, utilized an external clock board from Elmor and ran GPUPI v3.3 32B benchmarks for 35.377 seconds without 3D workloads. The result showcases extreme engineering but remains theoretical for real-world gaming or productivity tasks.

The setup included an Intel Core i9-14900KF at 6.0 GHz, ASUS ROG Maximus Z790 motherboard, 32 GB RAM, and a 3,000 W Corsair power supply. Liquid nitrogen was critical to stabilize the GPU beyond typical thermal limits. While impressive, this runs far beyond consumer use cases, relying on specialized hardware and extreme cooling not viable for average users. The achievement highlights NVIDIA’s Blackwell architecture potential but questions practicality for mainstream adoption.

This milestone matters as it pushes silicon limits, though its value lies in research rather than consumer impact. The 4 GHz mark symbolizes hardware evolution but requires context: similar extreme overclocking exists in cooling labs for decades. Without 3D workloads, the test doesn’t reflect gaming performance. Still, it underscores NVIDIA’s architectural advancements in Blackwell, offering a glimpse into future possibilities if optimized for real-world scenarios.
