IS 1.4v safe for this memory?
IS 1.4v safe for this memory?
I possess a vital RAM module DDR4 8GB (CT8G4DFD8213) with a rating of 2133 MHz, which is labeled at 15-15-15-36-51 1.2v.
I managed to push it overclock to 2933MHz using settings 14-17-17-44-61, but it wouldn't stabilize below 1.4GHz. Anything under that would cause issues. Should I be concerned or should I lower the overclock?
1.4V seems a bit too high at the moment. The DDR4 JEDEC standard covers voltages from 1.5v (DDR3) to 1.2V (DDR4), BUT it's worth noting that Intel itself certifies DDR4 as "XMP2.0" if the voltage stays at 1.5V or below... so, at least with Intel controllers, it should be safe.

Although Intel's XMP2.0 supports 1.5V certification, finding reliable information about RAM voltage from AMD is limited. AMD has stated that 1.45V is the maximum safe voltage for the CPU itself (with proper cooling), but the actual BIOS settings and continuous use would likely lower the voltage applied to the CPU. According to GamersNexus, the real voltage a chip receives can be significantly higher than what software suggests. Based on this, and considering that DDR4 voltages affect the IMC on Ryzen CPUs, I would lean toward around 1.35V for RAM/IMC. This is just an educated guess. Some premium kits (in the 3000-4133MHz range) are available at 1.35V, and a few appear in vendor QVLs. However, this applies only to Intel platforms. For AM4 boards from other manufacturers, I wouldn't trust third-party listings. Therefore, I would conclude that 1.5V is likely too high for Ryzen to manage, suggesting a safer limit of 1.35V.
