Question Can I add new pair of rams with different Voltage, timings?

[Bumernoy]

Hello guys,

I have Kingston HyperX FURY 2x8GB DDR4 PC4-19200 [HX424C15FB2K2/16] in my ASRock X570M Pro4 motherboard in 1 and 3 slots
Timings: 15-15-15
Voltage: 1.2

I want to add more RAM which should be compatible with the first pair.
I see it could be an option Kingston HyperX FURY 2x8GB DDR4 PC4-19200 [HX424C15FB3K2/16] for slots 2 and 4
Timings: 15-17-17
Voltage: 1.35

But new pair has different timings and voltage. Could it be an issue? Can I buy it and be sure it'll work fine?

Thanks in advance

Yes, you can. All RAM modules will just run at 1.35V and the worse timings.

I did something similar with an old dell machine. Worked fine but I wasn’t trying for the fastest & tightest timings.
Generally speaking it works but it doesn’t always work.

I failed to notice it is a ryzen board. Ryzens are great they are fussy about memory. Either plan on the memory working at a slow speed with lax timings or it not working at all. Bottom line I wouldn't pay for that memory.

this is YMMV... totally depends on the board, as well as the RAM.

Also i believe it will play massive HAVOK on a Ryzen1 or Ryzen2 system as those are picky as hell with ram to begin with.

IMO i honestly recommend you sticking with same ram speed / voltage and not do a hotpot of mixed ram for compatibility reasons.
You may think it works because it boots up, however you may in the future run into random errors.
So even if you have to pay a bit more, i would go with paring the ram with whatever you have in your system now.
