ASUS is making serious noise in the extreme overclocking scene, after its ROG Astral GeForce RTX 5090 graphics card reportedly shattered three 3DMark world records, including pushing beyond the massive 50,000-point milestone in the Port Royal benchmark.
What makes this result especially interesting is that these new records weren’t set with ASUS’ expected flagship-style “record chaser” model. Instead, the wins came from the company’s ROG Astral RTX 5090, a tier below the most elite variants enthusiasts typically associate with world-record runs. Even so, the card still managed to outperform the competition where it counts: in official benchmark leaderboards.
The record-setting run was achieved by renowned overclocker SPLAVE, who went all-in with a true extreme cooling setup. The stock cooler was removed from the ROG Astral RTX 5090 and replaced with a liquid nitrogen (LN2) configuration designed for maximum thermal headroom. The mod featured a well-known K1NGP1NG LN2 pot mounted directly over the GPU, along with a dedicated cooling approach for the power delivery components. Three blower-style fans were positioned to push air straight onto the VRMs, which were also fitted with custom copper heatshrink for improved heat handling during the session.
With temperatures under control, the GPU was driven to an eye-popping 3.7 GHz core clock. Memory speeds were pushed hard as well, reaching 36 Gbps across all 16 GDDR7 memory chips. Those numbers are the kind of frequencies that help explain how the card could climb to the very top of multiple benchmark charts.
Another detail that stands out to performance enthusiasts: the overclocked RTX 5090 Astral reportedly achieved these results while using only a single 16-pin power connector. That connector is typically associated with up to 600W of power delivery, and pulling off record-level scores within that limit adds an extra layer of intrigue for anyone tracking RTX 5090 power behavior and overclocking potential.
In total, three new 3DMark world records were attributed to this ROG Astral RTX 5090 run, with Port Royal being the headline result thanks to crossing the 50K barrier. Between the extreme LN2 cooling, the aggressive GPU and GDDR7 overclocks, and the single-connector power setup, ASUS has effectively set a new performance target that other RTX 5090 overclocking attempts will now be measured against.
