Nvidia RTX 4090 spotted running at 3.2GHz clock speed and 25Gbps memory clock

The Nvidia RTX 4090 isn't out yet, but some are lucky enough to have their hands on the new graphics card already. Previous reports have shown users pushing the GPU clock speed to 3GHz and 3.1GHz, but the current record sits at over 3.2GHz.

Twitter user @wxnod shared a screenshot of GPU-Z running what is suggested to be an overclocked RTX 4090 running with a GPU clock of 3,240MHz and a memory clock speed of 1,563Mbps (an effective memory speed of 25,003Mbps). Power settings are unknown, but considering the 3.1GHz overclocked card was pushing 493W, it's reasonable to assume this particular GPU is around the 500W mark.

At 3,240MHz, the GPU is running at over 700MHz above Nvidia's official boost spec for the reference card. As for the memory, it's 4Gbps faster than the reference card's specification. This memory overclock results in an increase in the maximum bandwidth, from 1TB/s to 1.2TB/s.

The Nvidia RTX 4090 graphics card will launch on October 12th with an MSRP of £1,679.

Kitguru says: Don't expect to see every RTX 4090 graphics card capable of such high overclocks. Still, it's quite encouraging to see there's still performance to squeeze out of the RTX 40 series flagship GPU.
