RTX 4080 Overclock problems.

[Bearman12345]

I Have recently acquired a MSI Suprim X 4080 and have started overclocking it using MSI afterburner. I can only get +70MHz on the core regardless of memory speeds. This brings the total boost clock of the card up to around 2910Mhz. 

 

The Power limit and temp limit are maxed out (125% and 88C respectively) and core voltage is at 100%. The temps are fine maxing out at 64C as the Suprim cards have beefy coolers.   

 

I have seen people getting around 3000MHz on there cards and was wondering if I was missing something that they were doing, maybe BIOS settings but I don't really know. 

 

New to overclocking so any help would be appreciated.

The clocks are temp sensitive. Maxing out voltage usually hurts the clocks as the card draws more power and gets more hot. You may find that staying at 0% voltage or even undervolting may push you a bit further.

 

64C is fine. But going under 60C will likely push your clocks higher by around 25-50MHz without even changing the clock speed manually.

 

Also check GPU-Z perf cap reason. It's more likely you're also hitting power limit which further limits your clocks. Increasing voltage makes you hit power limit even faster, which further limits your OC.

You should undervolt it to give it more power/thermal room for boosting clocks
