I deleted the EVGA PRE.X. and installed MSI Afterburner still does the same thing.
I can set everything higher, voltage,GPU mhz, but not the memory mhz speed.
Fan speed settings seem to work well as it did with PRE.X.
So I would have to say it is not a software problem, most likely. I think any way.
It's ok it's going real well, very stable at the settings I have.
Folds, crunches GPUgrid and primegrid with no errors.
Would be nice to know why we are having this problem, not going to lose sleep over it.
