Nah 1.6 is ok 24/7 on DDR4 (B-Die)

As long as you cool it B-die if tuned loses stability between 40 and 50C. On ddr4 a few dies can handle a lot of heat and voltage like Micron re E and B and Hynix DJR. Many dies hate voltage and temp like Hynix AFR, Samsung C, E etc.

LOL ive been running 1.8 for over 2 years now. 1.5V Seems fine for DDR5.

Project Farm on YT tested a bunch and it didn't make a difference worth a damn.

I saw that video, this is true.

No experience of Bdie but in overall... I've ran my 2x16 HyperX-3200 kit at 3466 1.38V (they just don't OC any higher) for ages

Damn, those are DDR2 voltages. Never ran even DDR3 at that high Vdimm :laugh:
