Got my CVF up and running, and it fails prime within seconds at stock clocks. Ive upped the voltage to 1.325Vcore, 1.66Vdimm, 1.2 CPU N/B, 1.2NB. Running a 1075T with turbo off, C1E etc.. off. LLC is on high, measured the volts with a DMM and they are pretty much spot on. Under water, only getting to 35C load. Ram is Gskill Trident 2k 9-9-9 1.6V, running 1600 8-8-8-24-2T 1.63v in BIOS, 1.66V DMM. The CPU has a VID of 1.275, and I had it running 3.9 stable with an H60 on an 880G mobo with 1.39v.
Tried setting dram vref on cpu to .8 from .75, and dram switching to 2x. Seemed to help the most, but I still get cores rounding .5 by the second pass. Using Prime blend settings in custom, with ram usage set to 2600.
