I'm trying to find daily io/sa values. I recently got my ram kit to 4400 19-20-20 bios vdimm 1.46v (hwinfo vdimm 1.48v) and still trying to stabilize (karhu, hci, my usage) them. Some times I'll settle for just one short-term testing and then it must not cause issues during my daily usage (nothing mission-critical, if anything, far from it).
In z370 taichi's bios, io/sa = 1.23v/1.27v, but hwinfo reads io/sa = 1.248v/1.288v. Since buildzoid's recent ram oc on z390 aorus master, I am sort of not afraid to try up to 1.3v for vccsa.
In the organized tables of the first post, there's maybe only a handful of samples that used >1.3v for vccsa (also the highlights helped to spot them, thanks OP). Noted 1.35v vccsa sample was under the description of uncommon/excessive voltage.
(image: Karhu's ram test, using slightly less thread and ram bc I'm actively using the system while testing too. Visual speck is really just the "gsync compatible indicator" at tiny res.)
