Upgrading Ram on my system from 2x8GB + addng 2x16GB - any problems?

[tankman1989]

I have a mid tier system (back when I built it) which I would like to upgrade a little. The problem is that when I looked for this system I chose the ram with the lowest latency and lowest timing. I've found a lot of 2x16GB sticks that have higher latancy and higher timing, though they may have lower voltage at 1.2v. IDK if the diff voltages is a problem, of if I should stick with 1.35 like wht I have. Also, will the system work if on channel has 2 8GB sticks and the other channel has 2 16GB sticks?

The mother board is an MSI Z370 SLI PLUS capable of 64GB of RAM

Here is what I was considering, largely b/c the price is right!

This one below seems to have the closest latency and timing and the speed is pretty close as it's DDR4 3000 vs DDR4 3200 which I already have. But it looks like anything above DDR4 2667 is considered overclocked, which I'd like to stay away from.

I just get confused between ram speeds, CPU memory speeds and MOBO speeds, then the latancy & timing & dual vs quad channel kits.


I wonder if maybe spending money on a CPU upgrade might not pay off more?

All the sticks need to run at the same timings, so as long as you try to run the RAM at the slower sticks speeds/timings you shouldn't have problem. I'm using mixed 2x8 and 2x16 with wildly different timings. One of my sets is single rank and Sk Hynix, and the other set is dual rank and Samsung.
I have zero issues at the slower ones XMP and all of them at 1.35v. When I attempt to overclock things (beyond XMP) it gets really messy so I don't.

They don’t have to be the same, but everything will default to highest timings (slower) and the lowest speed.
