LordredCan you fill us in with some basic information: CPU:GPU: eVGA RTX3090 XC3PSU:Power cable attachments When you open up a program like afterburner, what does this cards boost curve look like? How are the temperatures? Just get us the basics first, we know you cannot post pictures, or links yet.
BiOD0L3This may sound crazy, but did you test another PSU? I would give that a shot if you have another 750W (or greater) available at your disposal.

I have managed to fix the issue I believe. I have set performance mode to highest in the nvidia control panel and I can not hit 1980mhz and it stays there when gaming. A bit annoying as it means it only clocks to 1750Mhz when not in use
mcsands59Set the GPU performance to "prefer maximum performance" in Nvidia control panel for only the games/apps where you want maximum performance, and then set the global performance to "optimize" This will allow the GPU to downclock while idle.
delveyNext concern are core temps. Quickly hits 75°C and on warmer days more. Does this seem high? FTW3 review sees it peaking at 65°C under stress review

FTW3 review sees it peaking at 65°C under stress reviewThis is totally normal for an XC3 on the stock fan curve. Try using a fixed card and case fan speed with these high power cards, set them has high as the noise you can tolerate. It helps to have a MB software or the "Fan Control" freeware to tweak all the fans in one place while the machine is running, you can really dial in the noise of each fan vs. temps. It's easier to tolerate a higher speed when it's constant vs. ramping up and down. Then save a profile you can easily apply when you're gaming. With the fixed fans, when the card's power drops occasionally during gaming, the fans will keep going and cut down on the overall system heatsoak, reducing the peak temps under high load. Make sure your case fan config is such that the card gets plenty of air. Front AIO's are very restrictive usually prevent enough airflow from getting to an air cooled GPU.
delveyThanks for the reply. I am not running a stock fan curve. I'm running at 40% until it hits 40°C and then it increase by 10% for every 10°C. As you can imagine at 75°C it is quite noisy. I am already running fan control software. As I've said I have 2 SP120 under the GPU that go upto 70% depending on the GPU temperature (I have several fan curve in fan control, great bit of software). I have uploaded a picture of my case. I was playing PUBG last night and the side glass was hot too touch. I removed the side glass from the case but this only lowered the temperature down by 1 or 2°C, I thought it would have lowered it by much more
