Hi all. I have an Asrock x299 Extreme4 that I purchased in 2018 for use with a 7800x. About 3 weeks ago I purchased a 10920x to upgrade to the newer x299 cpus and get away from the sluggish performance of the 7800x. Upon installing the new cpu I upgraded to bios p1.90 and found that the system will not power on from an OFF state without first clearing the CMOS and then entering the UEFI setup and resetting the settings to defaults. All clocks are stock and set to AUTO. Windows 10 installed just fine and boots just fine so long as the power stays on. The system will reboot without issue. But if the system enters sleep mode or is powered off it needs to have the cmos reset in order to POST. Also, under load the system shuts down like someone pulled the cord. The Intel EXtreme Tuning Utility shows VRM Thermal Throttling is yellow YES all the time, even at idle. The VRM heatsink feels hot to the touch. The CPU temps are all in the low 40s at stock settings. The CPU is cooled by a hydro h100i v2 with 4 fans in push-pull another 2 120mm fans are in the top of the case and another in front above the radiator and one in the back of the case as well. The 7800 ran OC'd just fine. This beast won't even idle without pushing the thermal numbers of the VRM too high. ASRock is suggesting RMA'ing the board, but I'm wondering if the new board will be any better at handling the 10920x. Are there any cooling solutions to help cool the VRM better than the passive heatsinks on it? Perhaps something like the eVGA boards have with the active fans or even a water cooling solution? Any help would be greatly appreciated. Thanks!
