When I disable SMT in BIOS; motherboard, BIOS or Windows disables standby mode and I can't switch my PC to sleep mode.
Not just MSI, other mainboards are also have this problem:
Can you help me about this? I don't know why disabling SMT also disables standby mode.
My old processor (Athlon 64 X2 5000+) doesn't have SMT and it supports standby mode.
Why Ryzen doesn't support standby when SMT disabled?
Will AMD release BIOS update , agesa or something for this?
Disabling SMT, improves performance, lowers power consumption and reduces fps drop problems on some games.
So, I want to overclock it with 6/6 mode. But... no standby mode.
Standby mode on a desktop, especially with Windows 10, is fairly meaningless as Fast Boot brings you to the login screen within a few seconds anyway, less than 11 seconds for me.
If you think disabling SMT makes some games run better, and you want to use sleep mode on a desktop, then just disable it for those games by setting the processor affinity to use only the odd numbers in details. As for power consumption, it's not really a factor, even under Prime95 the difference is negligible.
8 threads, SMT disabled
8 threads, SMT enabled
I tried Cinebench for power consumption testing.
Stock Speed SMT OFF --> 56W max.
Stock Speed SMT ON --> 75W max.
I also watched some youtube videos. CPU has lower temps, lower power consumption and got better FPS on some games.
I didn't like fast boot, hibernation etc. things. I just want good old standby mode and AMD doesn't support it without SMT.
Do Ryzen 1200 and 1300X support standby mode ? (They don't have SMT feature you know.)
