LN2‑Cooled GALAX GeForce RTX 5090D Reaches 3,650 MHz Core, 36 Gbps GDDR7

Team OGS has demonstrated an impressive feat of extreme overclocking by extracting every last drop of performance from GALAX GeForce RTX 5090D HOF edition. Armed with a custom Extreme OC BIOS, authorized for up to 2,000 W of power, and two 12V-2×6 connectors delivering 1,200 W, the group cooled the card with liquid nitrogen and fine-tuned voltages to push clock speeds far beyond factory limits. In the GPUPI 32B benchmark, the GPU achieved a record-breaking core frequency of 3,650 MHz and a completion time of just 39.434 seconds, securing a new world record for GPU-accelerated Pi calculation.

The team’s success extended to graphics tests as well. In 3DMark Port Royal, the GPU operated at 3,570 MHz on its core and 2,250 MHz on its GDDR7 memory, achieving 47,469 points. Under Unigine Superposition’s 1080p Extreme preset, they maintained 3,540 MHz and 2,250 MHz, respectively, reaching 38,237 points, an increase of several thousand over previous records. Pushing memory speeds to an effective 36 Gbps translates into 2.304 TB/s of bandwidth, nearly 29% above the standard specifications. These results show the untapped potential of NVIDIA’s Blackwell architecture and suggest that, with similar power, cooling, and VBIOS modifications, professional cards like the RTX Pro 6000 series could achieve even more significant gains, given the higher CUDA core count.
