Gtx 980 voltage doesn't change incrementally

[IXFINGERZXI]

So I just picked up an MSI gtx 980 4g and I was doing some overclocking when I noticed the voltage acting stupid. I can only set min(1.218v) or max(1.243v) voltage under load. There's no in between. When I raise the core voltage to anywhere within the 0-18mV range the voltage reads 1.218v. When it's anywhere in the 19-87mV range the voltage reads 1.243v. This was not the case when I first started overclocking it. Anyone know how to fix this?

Have you tried talking to MSI?

Seems common. My 970 behaved that way, so does my 980Ti.

I'm using Afterburner. Anything over +40mV doesn't raise in game voltage any higher.
