Hello, I own two DDR4 2666 sticks in my gaming PC (CL19) that I've overclocked to 3133 MHz with a 1.3V supply. Neither stick has heat spreaders. Should I lower the voltage slightly? I'm considering upgrading to DDR4 3800 or even 4000 MHz since my motherboard supports up to 4800 MHz. However, my main concern is whether the current voltage is safe. I've run several memory tests and haven't experienced any blue screens, so I'm not overly concerned. Still, I just wanted to verify it. I have one 8GB TeamGroup 2666 DDR4 CL19 stick and another 16GB Patriot DDR4 2666 CL19 stick, both set for dual-channel.

Considering that most XMP profiles give 1.35V - I wouldn't be worried about running DDR4 sticks at 1.3V as a daily overclock. Obviously, overvolting inherently comes with risk of damage - no one here has a crystal ball that can tell you the future, and no one here has the magic RAM Checker 3000 that can be waved over a stick and say "this stick will only begin to suffer from noticeable degradation at exactly 1.387563V" or anything like that. With that said, if I were in your situation, I would feel totally comfortable running those sticks at 1.3V - I run my own overclocked at 1.38V so they can reach DDR4-3333 speeds, albeit they do have heat spreaders.

It works as long as everything functions properly

I operate two 8-bit modules at 3733 MHz and 1.42v, without heat spreaders, inside an ITX enclosure. Likely it's okay because the CJR-XNC chips are designed for higher voltages.

I wouldn't bother either. According to JEDEC standards, all DDR4 components are designed to handle a minimum of 1.35V, making 1.3V a safe choice if the voltage increases further.
