Asrock AB350 sleep Issue

[pra___izz]

iam using Asrock AB350 Pro4 with R5 1600 with the latest bios 2.50 and the latest windows 10 update.

i just notice a wired behavior, when a put my pc to sleep and wake up. I see on task manager the system interrupts constantly using CPU about 3% and also put 40% stress only on thread 0.
the benchmark test "after sleep" also resulting less score.

any idea what's wrong?
the issue gone as soon as i restart the PC

Since you're on Windows 10, you may want to try a repair install and see if the issue is averted but in all likelihood I'm speculating that the BIOS is at fault. More than anything the new Ryzen platform relies heavily on BIOS and microcode to help achieve optimal settings much like how Windows 10 require BIOS updates to perform optimally with corresponding hardware.

You could try and reflash the BIOS and see if the setting your power profile to high performance changes things when moving in an out of sleep.
