It's better to keep the voltage at 1.35V for stability, even if it means not lowering it to 1.3V. The default profile is set for higher frequencies, but maintaining a stable voltage helps prevent issues.

1.35V is fine for long term use. Unless you have a specific reason for lowering it I wouldn't bother, you'd save maybe half a watt of power draw at most and risk having instability, it's just not worth the effort.

It makes sense to give that reply.

You're probably using Zen+. If you're thinking about lowering the RAM speeds, 1.35V is fine and your RAM won't draw much power, so you won't be heavily undervolting them. You might gain more from boosting performance because the power usage and clock speeds are minimal. Some users with similar setups run at 1.7V for regular use without problems, and there are others using 1.6V with decent results. RAM voltage requirements vary by chipset—some systems like Samsung CMDI don't handle it well, but reports of damage at lower voltages are likely exaggerated. Both rev and BDE can support higher voltages, so you're mainly limited by your RAM module, platform, or cooling before voltage issues arise. I don’t worry about VDIMM and aim for the highest safe voltage possible, usually targeting 1.8V or 2/2.1V for DDR3/DDR4 depending on the chipset. I’ve had no problems with this approach, especially if I push my overclocking limits.

Some useful observations, though I’m not really aiming to boost the clock. Just checking if running at 1.35V matches the RAM’s rated speed, either way that’s fine.
