4ghz prime temps are 70C w/ load vcore 1.31 after 9 hrs small ffts. At 4.2 and higher, temps get toasty on load...just starting to bench now, will await new waterblock for higher mhz prime.

Interestingly, the turbo mode does not affect stability, despite being at 4.2 ghz...and this is likely from less vdroop with only 1 core loaded.
When more than one core loaded, no turbo, and 8 instances prime 4ghz is 9hrs small ffts stable w/ 1.31 load vcore (post 331).
When only one core loaded turbo kicks in to 4.2, but vdroop is to only 1.344 vcore (decreased load of one core), which is enough for that core at 4.2 (4.186 mhz turbo core 1 23x182) to be prime/orthos small ffts stable, tested by using taskbar to run prime/orthos small ffts w/affinity set to core 0,1 of 8.

I can leave turbo enabled, and get extra boost to 4.2 on single core tasks.
