I have an ongoing issue that is fairly minor overall, just highly irritating. I have a work around in place right now that is working okay, though not 100% optimally at all. It's a well known issue, partially, though it's persistence is proving frustrating as its supposed to be a solved issue I thought. The GTX 1080 Ti has some issues with down-clocking back to power saving mode on any driver version I try after about a week of running perfectly. If I reinstall even the same driver, it fixes the problem again, for about a week or so, then comes back randomly. The GPU clocks may even jump up to gaming speed while on the desktop and then not drop again with all applications closed, it is completely random seeming when it happens. Might be coming out of a game one time that it won't drop the clocks, but a week later after fixing it the next time might be just me browsing the net on Chrome (this is with GPU acceleration manually disabled for Chrome even!) or watching a movie or even just puttering around in Windows various interface screens. The temporary fix is only a partial fix. I am using Nvidia Inspector to force MDPS mode and then whitelisting the games and applications I want full GPU speed on. This is HIGHLY annoying! It does work, kind of. However, the clock it reduces to is nowhere near as low as normal idle clocks. Normally it goes down to 139mhz on the desktop in idle clocks. Once it sticks though, it stays at 1568mhz and will only boost up from there, never drops below again unless using MDPS mode, or reinstall the driver again. MDPS mode forces the clocks to drop to 608mhz, which is a huge improvement for idle temps over 1568mhz, but still nowhere near as low as 139mhz was getting my idle temps to. I have Windows 10 Pro x64 build 1703 and right now am on 384.94 driver version, though newer or older doesn't matter, same thing happens on ANY driver version. Works beautifully for a week or so, maybe up to 10 days, then the clocks just stick at 1568mhz minimum. I can't think of any more details to give beyond my specs listed in the specs section by my name, though specifically the GTX 1080 Ti in use is the Gigabyte Aorus non-Extreme version. In every other way, it runs flawlessly, and in MDPS mode it runs near flawlessly except not lowering the clock nearly far enough. If any more details are needed, please ask and I will provide them.
