    2080ti Power Throttling at 60C (at 40-50% TDP)

    I have a water cooled x299 build with a 7940x on a Rampage VI Apex. Less than 2 months ago I added an Asus Dual 2080ti OC card and it has been running fine until last weekend (have not even got around to overclocking it yet).

    I first noticed low performance in games. Inspecting the FPS, it looks to have been halved in some situations - running benchmarks like 3dmark gives me 8000-9000 graphics score on TimeSpy when before it would be 15000-16000. CPU score and CPU benchmarks are unchanged.

    Looking at the GPU sensors, temp seems fine (sitting at low 60C), usage is fine, what is not fine is Power % - the card starts off with my set power target (110%) but within a few seconds it falls down to 50% TDP where it stays. Performance is normal for those first few seconds (high FPS) but falls off with the TDP. PerfCap from GPUz in the below screenshot shows how this is happening (Pwr reason).



    Have tried changing drivers, even under-clocking the card. I have tried testing from a completely cold card (left computer off overnight, turned on and went straight into 3dmark) and exactly the same behavior happen - the common trigger seems to be when the GPU temp gets to 60C, the PerfCap: Pwr kicks in.

    Help please!

    I did have same problem with this issue with my asus rtx 2080ti. What i did is update to recent nvidia drivers and go to nvidia control panel and change the power management to = adaptive/performance and i got my score back.

    Thanks for the reply - I have tried changing it to both adaptive and maximum performance (and restarting between each test just for a good measure) but there is no difference. Power consumption spikes to 100% at the start, then drops to <50% within seconds with PerfCap throttling it.

    It's on water - any modern game is basically unplayable due to the throttling.

    Thanks - I'll give it a try (anything to avoid draining the loop AGAIN).

    What is strange is that it worked fine with the riser for almost 2 months before this problem occurred - will let you know how it goes.
