An ASUS ROG MATRIX GeForce RTX 4090 overclocked by Splave became the first graphics card to break the 4 GHz GPU clock barrier. The card was overclocked to a blistering 4005 MHz GPU clock while leaving the memory untouched at 21 Gbps. The card was GPU Pi stable, and went on to set the single GPU record of 45.402 seconds. The ROG MATRIX was cooled using a liquid nitrogen evaporator, while the Core i9-13900K powering the rig was on AIO liquid CPU cooling. The CPU was left at stock frequency, and the memory ticked at vanilla DDR5-4800. The HWBOT validation of the feat can be accessed here.
