Should I up my voltage or leave it the same?

I've just got into RAM overclocking so I've decided to do a simple overclock.
I'm using 4 sticks of Crucial DDR4 memory (total 16 GB) @ 2133 MHz (max MHz it's allowing me but also what it was running at out of the box).
My settings are:

Command rate 2
tCL: 13
tRCD: 14
tRP: 13
tRAS: 36
tRFC: 278

Default settings are:

Command rate: (not sure but auto had it at 2)
tCL: 15
tRCD: 15
tRP: 15
tRAS: 36
tRFC: 278

To accommodate this change, would it be necessary to up the voltage from the default 1.200 or the auto 1.248. What if I kept these setting but dropped the command rate to 1 (unless that's ill-advised). Would that affect required voltage?

Sorry I'm a noob but thanks for any help you can give!

#1 Memory overclocking for performance is usually only done with the 2 primary slots occupied, not 4 slots. Many M/B manuals plainly state the slots preferably occupied for this purpose.

Anytime you ask for help please post all your hardware specs in detail IE, brand, model #, amount, speed, etc. and the OP/SYS you are running, we are not mind readers.

#2 The gains you will get are really not worth the effort anyway as OCing the CPU yields much greater gains VS the memory especially if you are OCing the CPUs memory controller and adding heat to the mix.

FYI; Not all brands of memory are even overclockable and some of the cheaper brands could even be pushed over the edge and you end up with a machine dead in the water.

I've read that DDR4 ram must be able to operate at 1.5V in order to be certified. People are commonly running it at well over that with no problems so 1.25V certainly can't be a problem.

But the bigger issue is that it appears you are juggling timings/command rate and perhaps operating frequency to achieve optimal performance. For this, don't be afraid of high voltage at first...maybe 1.35-1.4 even. Once you've tested it for stability then lower voltage until it becomes unstable. Then you'll have to try it with some benchmarks to see if it's doing anything for you.

Yeah, a long iterative process unless you've the good fortune of finding someone else doing the same thing with your memory and can share their experience. By the way, those types tend to be using Samsung b-die memory which behaves much differently anyway.

good luck
