Choice of RAM, 4x8GB or 2x16GB?

Question

RAM

Hello. Kingston HyperX Predator 3200 Kit [HX432C16PB3K2/16] 16 GB (2x8) is now available. For games with a head, but for work it has long been lacking. The question is, to buy another set of the same, will there be 4 dice, or sell the current one and buy two slats (2x16)? Is it worth it? What will be faster?
UPD: PC 8700K, Z370

Answer 1

judging by the intel site, moms on the Z370 come with 2 bars per channel. including dual-channel maximum
choice only for the financial component and the likelihood of a future upgrade to 64G

Answer 2

if you buy 2 dies with the same frequency as the 2 previous ones, then it will work in four-channel mode instead of 2x, which theoretically gives an increase in throughput by almost 2 times. 64GB is hardly planned, most likely, a new PC will be needed, so it's better to finish off 2 more. PS ideally it is better to take as 2 available 1 in 1
