Windows 10 Sleep Mode with ASRock X670E PR RS

Hi!

I recently bought a new computer which includes a ASRock X670E PR RS.
My OS is Windows 10 Pro and from my old computer I am used to being able to set Windows 10 into the sleep mode by clicking start -> on/off -> sleep.
This option is missing, and I can't enable it in the power save options because the option is not there to select.

I guess this might be because of some settings in the bios, but I am not completely sure.

I hope someone here has an idea.

Hi.

I tried to install it and in the device manager I have multiple ACPI entries. In 'Computer' is 'ACPI x64-based PC'. In 'System devices' there are three entries with ACPI in their names.
I installed the AMD drivers but there is still no option in the energy saving plan section for sleep.

I have the same problem, like you.

If I use the XMP profile, i missed the sleeping mode in windows.

With the Standard Auto Clock (4800 Mhz RAM Clock) it works fine.
But if I try a faster RAM Clock or manual Settings, I get some various bugs.
With the XMP profile: I lose the sleeping mode and the system can´t reboot.
With manual clocks, I have the sleeping mode, but the system can´t reboot. I don´t know which option the problem is.

I think in the bios are various bugs. I hope Asrock will bring a stable BIOS-Update soon, so that everyone can use his RAM.

Looks like even using default 4800MHz clocks (XMP profile) on 2 sticks of KF548C38BBK2-64 with my X670E Pro RS 1.11 creates some problems.

If I will try to use stanby mode for more than ~8 hours (it's a blind guess, got to check it correctly), then after waking up, my LAN card and BT is gone.

"Miniport: Realtek Gaming 2.5GbE Family Controller, {c5d30d35-345e-4886-8ee8-e9a6f72d788e}, event: Fatal error: The miniport has failed a power transition to operational power"

The only solution for this is to power down the system, unplug a power cord, wait a moment, press a power button for a few seconds, replug it and turn on again.

For a few years I am using Windows - only switching it to standby mode (got to have some browser tabs loaded with predefined settings right after sitting to my computer).

In a time perspective, x399 Taichi got similar problem with standby mode, sometimes didn't wake up properly or just crashed, after few years and few newer bioses it got better but still crashes sometimes, the funny thing is, it gets relatively stable after latest 3.92 beta bios, which recently I found out just ignores chosen @3200 XMP profile and still uses 2133Mhz settings to make it stable. LOL

I would like to push this topic up again because the last official none beta bios update ist from 2022/10/25.

Hey ASROCK, are you guys in hibernation? It's about time to release a new none beta bios version!
