Hello

Looking to buy msi tomahawk Z690 ddr5 and to pair with this ram along with i7 12700k,i cant figure out which of these sticks are 1DPC 1R Max speed up to 6400+ MHz

KF564C32RSAK2-32
KF564C32RSA-16
 
They're the same, I think, but the first one is a kit (2x16GB) and the second is a single stick (1x16GB).

According to the datasheet, they're singled ranked modules (1Rx8), 16GB per stick.

1DPC means 1 dimm per channel and I don't think that refers to the memory, but the max speed of the CPU or the motherboard.

You would need to buy a 32GB module for it to be dual ranked (2Rx8), I believe.
 
Msi says 1DPC 1R is very related to the memory, so which model i need to buy to get 6400mhz 2x16gb or 1x16gb? Msi says with dual ranked memory i cant get 6400mhz
 
In the specification from MSI, they say it is "max overclocking frequency" for the motherboard. So, this is the maximum frequency supported by the motherboard, but not by the CPU.

1DPC 1R means two sticks (1 per channel), which are both singled ranked.

The Kingston kit (according to the datasheet for the single module), uses single ranked modules.

I don't think there are any 2R 16GB DDR5 sticks, so you're probably safe (for 1R: single ranked) with any kit that has 16GB sticks.
