Hi, ive been noticing some stutters in some applications, and am trying to narrow down if its just the applications acting up or if its related to my OC. Ive been running these settings for awhile. Do the variations in linpack suggest fclk instability? Specs and timings are in the second image, and VDDG IOD/CCD are both at 1000mv.

The ram itself is stable in relatively quick tests, it passed 4 hours of tm5 anta777 x3d and 5 hours of ycruncher vt3. I have yet to run overnight tests.
