Hi,

I am using AB350 Pro4 motherboard with the latest 2.50 BIOS.
Configuration is:

CPU: AMD Ryzen5 1500X @ stock
RAM: 2x Kingston HyperX Fury 4GB, 2400/15-15-15-35 @2400/13-14-14-34 (KHX2400C15D4/4G)
GPU: XFX Radeon RX480 XXX BP (reference 1288)@1300
PSU: Corsair VS450

Fan configuration:
Wraith Spire SR2 (no LED)
1x Arctic F12 (4 pin, PWM) > CHA_FAN1
2x Arctic F14 (3 pin, on Y splitter) > CHA_FAN2
1x Arctic F14 (3 pin) > CHA_FAN3

My issues since day one (BIOS 1.30) are:

1. When Enabled, Deep Sleep feature works in 1 out of 10 cases
   - ASRock Support suggested me a workaround - disabling Fast Boot in Windows
     (I must turn off Windows feature in order to have Deep Sleep work properly!)
2. Fan readings are sometimes insane (huge RPM like 19000, 49000, 61000)
   - this makes creating any fan curves (excluding BIOS) impossible
   - fans are 100% functional, tested on 3 differently aged systems
   - my latest discovery was that ONLY 3-pin fan readings are going insane

Any ideas? Deep Sleep seems to be solved, I am not happy, but its is working.
Fan control is important for me, is there any way to fix this (buying and trying another fans is not an option, since these fans are functional and worked just fine on my B85 system!).

BR,
DonYenko
