Question 7900 XTX only 70-80% usage

[mrmaruniversal]

Hopefully you guys have some answers, could just be because It DOESNT need to be at 100%. But anyways picked up a i9 14900k with a 7900xtx. Plays games great at 1440 and 4k. Usually play at 1440. However I noticed that it will only use 70-80% usage in games. Like to sit at 75% to be precise. It WILL go to 90 or 100% but not often. I have the latest drivers and thats pretty much about it. It runs 2500mhz at 800-900mV. Overclocked to 3033 it sits at 980mV, but still draws 400W from stock or OC. I have never seen this card run 1000mV or 1150mV.

Here are the games I play that that this happens in (pretty much any game)
Red Dead Redemption
Hogwarts Legacy
Sea of Thieves
Modern 2 & Warzone
Fortnite
Cyberpunk 2077
FNAF Security Breach

Here are specs

CPU: i9 14900k (No thermal Thottle) (Power Limit = 350w)
GPU: 7900XTX (Max Tjunction hits 80-90) (Reference Card) (No Vapor defects)
RAM: 32gb 3200Mhz TridentZ RGB DDR4
Case: Corsair 4000D airflow
Cooling: 3 Exhaust fans
Cooling: 360 Rad Intake
Storage: 3x 980 Pro 2T
PSU: EVGA 850W Gold+ SuperNova (Fully Modular)
Motherboard: ASUS Tuf Gaming D4 Wifi

Only thing I can think of is maybe some power saving features somewhere, could be DDR4, or PSU but im lost.

If game play is unaffected and performance is stable then the system is fine at 70-80%.

My suggestion: leave well enough alone AKA "if if ain't broke then don't fix it".

There are always trade-offs and if some way is found to force 100% then that is likely going to end badly.....

100% is sometimes not a good thing.

The normal blood donation is about 8 - 12%. Very sure that 100% is not good.....

You do not want either cpu or gpu to run at 100%
There are always peaks and valleys in demand for these resources.
And these resources are not always consumed in parallel.
Running at 100% leaves no room to handle peak demands.

I kinda figured. Thank you both for your input, on another note. Running 2300-2500 Mhz at 980mV. Would you consider this normal aswell? (Good silicon?)

DDR5 vs. DDR4 Gaming Performance

It's time we take a fresh look at DDR4 vs DDR5 memory performance using the Core i9-14900K. We're benchmarking with fast DDR5-7200 and DDR4-4000 memory, noting that...

This is done with significantly better DDR4 than you're using.

Also of note is that if you're not noticing a difference when the card is running much higher clockspeeds that's another indicator the video card isn't the issue.

I would expect upper 80s-mid 90s percent usage for GPU bound workloads.

Decided to bite the bullet and upgrade to DDR5 today. And yup, DDR4 was the issue. High clocks, better performance, better everything. Thank you
