Safe voltage for ddr4
Safe voltage for ddr4
I believe 1.36v is fine, it's the default setting on my motherboard with a minor boost to 3ghz.
Certainly, the values under 1.4 are acceptable as long as there is adequate airflow nearby.
1.35v is the standard power level for xmp profiles on DDR4. For instance, with 32 gigabytes of 3200mhz RAM operating at 1.35 volts.
1.4V works just fine and 1.45V is generally safe. I haven’t found any DIMM modules without temperature sensors, though those sensor readings aren’t always displayed in every tool. HWInfo64 seems to be the top choice for compatibility with most sensors.
I’m comfortable with 1.5 daily, as G.Skill offers comparable B die sets running at 1.5v. Experienced overclockers suggest 1.6v is fine—just ensure proper airflow. Raising the voltage to 1.64v triggers a red warning on my BIOS. They recommend up to 2v for bench testing, but keep an eye on temperatures. At 1.5v, my four cores run at roughly 30-32°C, with idle temps dropping to 23°C or less. The cooling performance improves here. My Black and Whites lag behind the Royals, so they require a bit more power.
