   Hi, my mobo AB350M PRO4 doesn't maintain or apply some bios setting in particular:
1) all multiplier with final xx.25 (like 38.25) under windows results is xx.00 (like 38.00), i can restore the correct setting under win with A-tuning utility
2)bios after reboot doesn't maintain 1.40v on ram/dimm voltage 
3)my dimms Corsair LPX 16gb (8x2) 3200mhrz CMK16GX4M2B3200C16 6 v5.39 doesn't boot at nominal speed of 3200mhrz vith 1.35v; max is 2933mhrz with 1.40v but bios doesn't maintain the setting voltage then the max speed is 2800mhrz with 1.35v.
Dimm are in slots A2 and B2 and I've tried changing  procODT to 53.3 or 60 omhs .

Can i try some other things?

	Hello, it is due to the quality of the memories. Some v5.39 run and others do not. try times only one in the change whether one with 3200 MHz functions. otherwise get the same only with v4.24 (Samsung chips)
