correct 980x CPU PLL Vcore voltage

post #1 of 6
Thread Starter 
I'm playing with a very small OC on my 980x. I was leaving CPU PLL on Auto but I noticed the Auto setting defaults to 1.8 which seems awfully high. Lowering to 1.6 produced no ill effects. Does this sound ok? I'm a bit new to this and there seems to be less info on safe/correct Cpu PLL vcore voltages.

Same question. I lower my PLL to 1.5v and nothing happens. I left it on 1.89v default oc to be stable safe, but I'm pretty sure thats very high?

A bit of searching found a number of people running 1.8 at default on a variety of mobo/bios but no conclusion as to whether this was too high, or could be right.

1.8-1.88 are rather normal PLL voltages and your 980 will most likely be fine anywhere in that range. However, some people have had problems stabilizing their OC's with the PLL in that range and found that decreasing it to 1.76-1.79 actually helped more than bumping their vcore or other settings. Tconroy is one of those people if memory serves me correctly.

Edit: After a decent search I have returned with a gift:

Here's a bunch of the 980x owners discussing their settings and findings.
