winsat mem 45,038.56 MB/s, up from 35,887. That's a 25.5% improvement. Memory Read speed is up 22.5% and Latency is down 6.8%.
The overall effect on performance may not be Earth shattering, but if I had to buy the performance I now have, from scratch, it would run me $889 for a Z270 direct replacement for my mobo, a 7700k and G.Skill 3866 MHz RAM (because my timings are tighter than their 3733 MHz kits) at newegg prices. So what if my overall performance only went up a couple percentage points? I'll take $900 worth of free stuff any day. And almost everything I did, I learned at OCF.
I don't know about the cool kids, I used the trial version of Aida64. I kept VCCIO and VCCSA both under 1.20v (measured). I forget where exactly I got that spec (I believe Woomack was one source), but that was the max I settled on.
i figured out aida64 but didn't know i could go that low on vccio and vccsa. ill try lowering it even more. it's hard to believe they would put it so high at auto. it's like they want to destroy your cpu.
idk it seems like most people lower it. they should be conservative and if people need more voltage they can find out when they call tech during troubleshooting. obscure voltages at super high levels seem like a bigger danger to me since they could stay that way indefinitely until the imc dies and nobody would be the wiser. just my opinion.

I thought I read 1.20v was the max for my chip, but the datasheet is 260+ pages for Volume 1. Haven't gone back through it lately. LOL
It is 1.52v at 100AMPs = 152 watts maximum. Intel also states on that page the Voltage and current specification are only valid meeting specifications for clock frequency.That's where I got the max voltage of 1.52v from, which seems to generally be accepted as the limit for my Skylake.

The Rule: Maximize frequency and minimize voltage while extracting as much heat as possible so the system remains stable. https://www.intel.com/content/www/us/en/gaming/how-to-overclock.html
