TECH NEWS: A year and a half after launch, Team OGS pushed the graphics card’s clock speed substantially using the Galax HOF OC Lab version.
It was bound to happen sooner or later, but a year and a half after launch, the Nvidia GeForce RTX 5090D has achieved the highest clock speed ever recorded on a Blackwell GPU. The Greek Team OGS set this remarkable record on HWBOT.
For the test, the team used a Galax GeForce RTX 5090D graphics card, not the newer V2 version but the older model featuring GPU-core specifications identical to those of the standard RTX 5090. The V2 version, by contrast, uses a reduced core and memory configuration.
The specific model was the Galax HOF OC Lab, which features two 16-pin connectors and an astonishing 36-phase power delivery design.
Team OGS explained that it replaced the stock 27 MHz crystal with an Elmor ECB, or External Clock Board. Extreme overclockers use this board because it allows hardware modders to bypass the integrated clock source with an adjustable external reference clock.
This allowed OGS to reach 28.7 MHz, representing a 6.3 percent increase. Consequently, all GPU-related frequencies increased by the same 6.3 percent. That also applies to VRAM, whose frequency was raised to 1860 MHz from the 1750 MHz reference value.
Interestingly, extreme overclockers can reach as high as 2400 MHz with GDDR7 using the same ECB board. That would translate to 38.4 Gbps, compared with the standard RTX 5090’s 28 Gbps.
The Nvidia GeForce RTX 5090D was tested in GPUPI v3.3 – 32B, a synthetic benchmark focused exclusively on GPU performance. The graphics card achieved an impressive overclocked speed of 4002 MHz, or 4 GHz, while the memory ran at 1860 MHz, close to 30 Gbps.
With this tuning, Team OGS completed the test in 35.377 seconds, breaking the previous record by more than one second.
Extreme overclockers have already used the Nvidia RTX 5090D in numerous record-breaking tests. The highest speed before the 4 GHz result was 3.88 GHz, set by Splave, which makes this a genuine milestone. AMD nevertheless still holds the highest GPU-frequency record, with the Radeon RX 9060 XT reaching 4.769 GHz a few months ago.
