Run a custom blend test, 90% of ram set to 1 minute (I think that's the option) 1344/1344 (I think) and 1792/1792. If it is fine for at least 20 minutes each, you're more than likely good. If any hiccups, bump the vdimm a notch. If you get nothing, you're good. Then run it for like 4 hours. Good? Then success.Also make sure the cpu is set to stable voltage (+1 notch is fine just in case, tune down later), at factory clocks.
