Asus ROG Strix GeForce RTX™ 4090 OC Clocks

Level 7


I've recently become a happy owner of an RTX 4090... well, maybe not entirely 🙂 My Asus ROG Strix GeForce RTX 4090 OC card out of the box has a maximum Boost clock of 2655MHz. If you look at the official Asus website, everything seems to be correct, but my friend bought the same card and his clocks out of the box are 2745Mhz. I looked on YT and no one has clocks as low as mine on the 4090, usually they all oscillate around 2750Mhz.

My set:
CPU: Intel i9 14900K 
RAM: G.Skill Trident Z5 RGB 7200 CL34-45-45-115 1.40V
GPU: Asus ROG Strix GeForce RTX 4090 OC
MOBO: Asus ROG Strix Z790-E Gaming Wifi II
PSU: Be Quiet! Dark Power Pro 12 1500W

Bad silicon lottery, or I missed something?

Hi @Butterflyewski 

Those boost clocks are typically what you'd expect, but thermals, power and silicon quality all have an impact on GPUBoost 4.0 behaviour

Which BIOS mode is the card currently in? Make sure the switch is in the P-Mode position.

Thank you for your answer, yes the BIOS is set in P-Mode.
The only thing that comes to my mind is that my friend has an ATX 3.0 power supply and a dedicated 12VHPWR connector, while I have an ATX 2.x without a dedicated 12VHPWR power connector. It is possible that this has some impact on more precise voltage regulation in the graphics card, hence the better result.

No, it won't influence boost behaviour. Using the bundled adapter or a native cable should make no odds. Check power consumption under 3DMark / TimeSpy Extreme. Using HWInfo or GPU Tweak III

Unfortunately, I do not have the full version of 3DMark. These are the results from 3D Mark Time Spy:

That score is fairly typical, so no issues there. This is the TUF water-cooled at factory clocks.
