System remains active after reboot (shutdown process works)
System remains active after reboot (shutdown process works)
I've experienced the same problem with my recent upgrade for a while now. It's not a major concern, but it could turn into an issue if the system restarts during a critical update and can't handle the process properly. The machine won't restart on its own (though it sometimes doesn't shut down completely, but behaves similarly). I can manually power off the PC using the case button and then turn it back on—everything works fine afterward.
The build I'm using is a Ryzen 7 7700X with MSI B650 MAG Tomahawk WiFi, 32GB g.Skill DDR5-6000 memory, Sapphire Rx 7900 XTX, 1TB NVMe SSD, and a 2TB PNY Gen4 NVMe drive. The power supply is an 850W Rm850x from Corsair.
I've looked into replacing the motherboard based on other forums, but I'm still facing the same problem. My suspicion is related to the RAM and EXPO profiles; memtest shows no errors in either setup. Currently, EXPO profile 1 is set in the BIOS, yet it doesn't appear as configured in Ryzen Master for profile 1. However, the memory seems correctly recognized at 3000Mhz (double). It's a bit puzzling.
Adjust to 5600 for better stability with Ryzen 7000. Also, ensure all chipset drivers and BIOS are up to date.
Is Fast Startup active? This setting in Windows can lead to problems when shutting down or restarting. To turn it off, open Control Panel, select Hardware and Sound, then Power Options, choose what the power buttons do, click "Change settings that are currently unavailable," uncheck "Turn on fast startup (recommended)," and save.
I've upgraded to BIOS version 1.3 and the newest chipset drivers. I didn't install the latest 1.50 update for that motherboard because I was worried about the restart problems and potential bricking. I might attempt to set it to a base clock of 4800Mhz to see if it can restart before trying the BIOS update. It seems uncertain either way, though.
Reviving an old discussion thread for anyone still facing this problem. I encountered the same issue before and resolved it by turning off EXPO and adjusting voltages and timings manually. Here are the steps I took:
- Disabled EXPO
- Set DRAM frequency to 6000MHz
- Restored memory context (disabled)
- Adjusted DRAM voltage to 1.40V
- Set VDDQ to 1.40V
- Set VDDIO to 1.40V
- Configured CPU NB/SoC voltage to 1.25V (not actual DRAM voltage, but the SoC holds the controller)
- Ran at 1.306–1.308V during Auto mode, slightly above the safe range of 1.3V
- In Advanced DRAM Configuration:
- tCL: 30
- tRCD: 36
- tRP: 36
- tRAS: 76
These settings depend on the specific DRAM model, usually indicated on a sticker on the RAM module. Once done, the PC restarts smoothly and the RAM operates at the desired speed. Gaming runs stably with controlled temperatures.
