Question Windows 10 gradually freezing after a long sleep state (detailed within) ?

Jun 25, 2021
I’ve been dealing with this for three months on a new workstation. The PC is working great, except for sleep states. Right now I’ve just accepted that sleep is not an option on this machine, but someone might still have input on this and I’d love to hear opinions.

Detailed issue:
  • 20-40 minutes after a long (6+ hours) sleep state Windows 10 pro is gradually freezing (mouse moves, applications won’t close, UI stops responding, until a complete halt.)
  • This does not happen after a short sleep state (1-2 hours)
  • Only way to resolve this is a forced restart via the power button.
  • Nothing in the Reliability Report.
  • No MiniDumps.
  • No BSOD.
Hardware (where there are two options I’ve switched out components for testing, everything has been stress tested thoroughly with no issues coming up.):
  • MB: Supermicro x10DAi (Asus z10pe-d8 WS)
  • CPU: 2 x Intel e5 v4 2699 Xeon processors
  • GPU: RTX 2080
  • PSU: EVGA 850 Gold (Gigabyte 1000 Gold)
  • RAM: 128GB Samsung RDIMM ECC
  • HD: Samsung NVME as boot (Crucial SSD as boot / WD HDD as boot)
Other info:
  • All drivers are OEM, and if available, multiple different drivers were tested.
  • All components were tested, this includes GPU, CPU, RAM
  • No USB connected was tested.
  • Everything is updated.
  • UEFI
  • Barebones fresh install with nothing but mouse connected to single windows 10 PRO SSD drive.
  • Did try with previous builds of win10, same results.
  • Temperatures are great.
  • Hibernation is OFF, Hybrid Sleep is OFF, the Motherboard only allows for S3
  • I’ve seen the GPU go to either 100% or -1% in taskmanager while this is happening. If the screens go into standby while the freezing occurs, they won’t wake back up on moving the mouse or any other input.
Powercfg -a returns:
The following sleep states are available on this system:
Standby (S3)
The following sleep states are not available on this system:
Standby (S1)
The system firmware does not support this standby state.
Standby (S2)
The system firmware does not support this standby state.
Hibernation has not been enabled.
Standby (S0 Low Power Idle)
The system firmware does not support this standby state.
Hybrid Sleep
Hibernation is not available.
Fast Startup
Hibernation is not available.

The only thing I get in Event Viewer is:
Kernel 137 “The system firmware has changed the processor's memory type range registers (MTRRs) across a sleep state transition (S4). This can result in reduced resume performance.”
This message only shows up with the x10DAi Motherboard after a sleep state. The z10pe-d8 WS does not show this message after a sleep state, it has the same freezing issue though.

So my best guess here would be the ram. It is not faulty though and didn’t show any error when thoroughly testing with a memtest boot.

Is it possible that a ram module just ‘doesn’t support sleep states’?
Why would this only happen after long sleep states, but not short ones? What’s going on with the ACPI management?

Any input is appreciated!
