Over 1.5v on B-die DDR4/AMD safe?

[Mr. Sunshine]

I know there are a lot of older post about this topic but I was wondering what everyones thoughts are on pushing past 1.5v on B-die DDR4. I know that there are some kits out there that (Gskill, Corsair)run 1.5v.

I'm running Patroit Viper 4000mhz 32GB(4x8GB)@ 3800(14-10-15-28-42) 1.53v Memtest ran for over 24hr(2000%) no errors. Long term do you think this will be ok? I know that Adata has some kits that are spec'd @ 1.6v(https://www.xpg.com/us/feature/686/) so I was thinking that I might be ok.

Thanks for the info guys. Heat shouldn't be issue. System is custom looped WC with 360/480 rads with 12*120mm fans. I also have 2*140mm pulling air out the top across the dimms. Great read on Igors lab good stuff.

Tightened up timings as much as I could. Not bad for cheap B-die 32GB(4x8) on a x470 board. Getting sub 54ns in Aida64. Might get little better with new BIOS. Will test to see if I can drop voltage on SOC
