Unleashing the Power of NVIDIA’s GALAX HOF OC LAB RTX 5090D: A Record-Breaking Overclock at 4 GHz
The world of extreme overclocking has witnessed a groundbreaking achievement as Team OGS from Greece pushed the boundaries of performance with the NVIDIA GeForce RTX 5090D. This remarkable feat marks the first time a Blackwell GPU has soared to a record-breaking overclock of 4 GHz, setting a new standard for high-performance gaming.
Achieving the Unthinkable: Team OGS Shatters Records
After a year and a half since its launch, the NVIDIA GeForce RTX 5090D, housed within the GALAX HOF OC LAB, has made history by achieving the fastest clock speed ever recorded on a Blackwell GPU. Team OGS showcased their overclocking prowess at HWBOT, showcasing the immense capabilities of the GALAX GeForce RTX 5090D graphics card.
“First RTX 5090 @4GHz Core! (ECB @28.7MHz / +106.3%) cooled by Bitspower Strata LN2 GPU Pot and Kryonaut Extreme. Thanks to Galax, ASUS, Corsair, and Thermal Grizzly for the support!”
The GALAX HOF OC LAB, equipped with dual 16-pin connectors and an impressive 36 phases, proved to be the perfect platform for this overclocking milestone.
Unveiling the Technical Wizardry Behind the Overclock
Team OGS shared their strategic approach, revealing the replacement of the stock 27 MHz crystal with Elmor’s ECB (External Clock Board). This innovative board allowed for an external reference clock, resulting in a 6.3% increase in clock speed and a boost in GPU and VRAM frequencies. With the ECB board, extreme overclockers can even reach up to 2400 MHz clock speeds for the GDDR7, unlocking new realms of performance.

Testing the NVIDIA GeForce RTX 5090D in GPUPI v3.3 – 32B, Team OGS achieved a remarkable 4 GHz overclock speed, coupled with a memory running at 1860 MHz. This feat propelled them to the top spot with a completion time of 35.377 seconds, showcasing their dominance in the overclocking arena.
Looking Ahead: A Future of Innovation and Breakthroughs
While this achievement is a significant milestone for the NVIDIA RTX 5090D, the overclocking community continues to push the boundaries of performance. With AMD holding the record for the highest GPU frequency, the competitive spirit remains strong. Team OGS and other overclocking enthusiasts are poised to unveil more benchmark records in the future, promising an exciting journey filled with innovation and breakthroughs.

As the world of extreme overclocking continues to evolve, the possibilities are endless. Team OGS’s groundbreaking achievement with the NVIDIA GeForce RTX 5090D sets a new benchmark for performance and innovation, paving the way for future advancements in high-performance computing.
