RAM voltage question, Ryzen 7 5800X

[pugnobellum]

I am starting to put together a part list for a new gaming rig. I am looking at memory and came across this issue noted by pcpp:

•  Note:The G.Skill Trident Z Neo 16 GB (2 x 8 GB) DDR4-3600 CL14 Memory operating voltage of 1.45 V exceeds the AMD Zen 3 CPU recommended maximum of 1.35 V+7% (1.444 V). This memory module may run at a reduced clock rate to meet the 1.35 V voltage recommendation, or may require running at a voltage greater than the AMD recommended maximum.

I was wondering should I just keep the same sticks and change to CL16 (which changes it to 1.35 V) or is this not a big deal? And any explanation would be helpful. Thanks!

It's not a big deal at all. 1.45V is above stock spec, but it's well within margins of safety for DDR4 RAM. Higher-end RAM runs at higher voltages due to higher frequencies or better timings like in this case. This message is just a note, which honestly is quite pointless.

DDR4 can run on 1.45V all day long. I really wouldn't worry about it. Just make sure that the memory you are getting is on the QVL of your motherboard. With high-frequency kits becoming more prevalent checking the official compatibility list is kind of important.

I'm running same CPU mobo and RAM. Been tweaking all week, and right now its at 1.5v at 3800 cas 14, temperature for them sit around 20-23c above ambient in a full memtest pro / prime95 torture. All 4 are covered by the NH-D14's 120MM CPU fan and there's just the one 120MM intake. I had it at 1.5v going for 4000Mhz and just haven't set it back yet. I'm actually running two kits of the 2x8 so I'll probably stay around 3800/3833 for compatibility. I'll probably knock it back down to 1.45v when I feel like I'm "done" and never worry about it again.

I’m ok with 1.5-1.55 daily if they need it.
