GA-990XA-UD3 Rev 4 BIOS Vcore control issue
« on: July 21, 2014, 08:59:04 pm »
Hello,I will try to make this short so you don't have to read a wall of text,I'm using a GA-990XA-UD3 Rev 4.0 motherboard and I need to have manual control over the voltages in BIOS so I can properly overclock and get it stable,but for some reason I can't select manual control,it's just on auto and it won't let me set the desired Vcore,I can only add or take 0.25v from the default value and the motherboard will still control the voltage automatically and just add or take the 0.25 or 0.50 etc that I add in,Bios version is FD and I saw on youtube a guy that had a somewhat different bios for the 990fxa-ud3.

here's how his bios looks,mine looks pretty much the same except for the fact that I don't have that dynamic vcore line,I just have the exact First line that he has which is CPU VCORE and I can't add a specific voltage like he did,I can write the vcore I want but it will deny it and just set it back to auto instantly :(,I can only use the + or - buttons to add or take 0.25v from the default value and the motherboard will stay on auto.. Does anyone have an idea of what I can do? I know the motherboards are different but do they really have that big of a difference? I mean the power delivery is pretty much the same why can't I just set what voltage I want on a XA board and he can on a FXA. Is it a bios version related? When I go to the official site and look for the last bios I can see that the FD version is the last one,does anyone know a solution?

that's how his BIOS looks

and this is how mine looks.





I have 3 options,let it on auto,normal ( if i try to add any value over normal it sets it back to auto ) and adding +0.25 as you can see over there,if I try to write 1.375 for example or 1.37500 it will set it on auto again as soon as I hit the enter button,I'm frustrated as hell...

Do you have cpuz installed. If so overclock CPU by multiplier then hit f10 save and exit then enter when it restarts check cpuz for you voltages. On mine I just have to set multiplier it auto adjust voltages and I can see what it is set to thru cpuz.

Weird thing is I can then go in and set it to what cpuz showed it as and it keeps that value.
