  • Which is preferable for DDR4 Overclocking: 4x8GB or 2x16GB?

    For some reason, all of the high-frequency (4000 MHz+) and tightly-timed (e.g. 3600 MHz CAS 16) 32GB kits are sold in the 4x8GB configuration, and there are very few mentions of 2x16GB kits in motherboard QVL lists. UpToDate

    It makes me wonder: Is the 2x16GB configuration sub-optimal? Are DIMM manufacturers just taking the easy out and doubling up 2x8GB kits whenever possible, where they are focusing all their R&D? Are the 4x8GB kits getting higher-binned B-Die? MapQuest

    If my goal is 32GB @ 4000 MHz with the lowest latency possible, would I be better served overclocking a DDR4 3733/3866 2x16GB kit, or by tightening the timings on a DDR4 4000 4x8GB kit? Rufus

    Best config also depends on the CPU in use. Some have dual channel, Tri channel, Quad channel and even 6 RAM channels.
