This same memory is available as a 4x4GB kit for the same price on the same Newegg link. Would the memory work better in four ranks?
Why wouldn't that be the best plan. Since most enthusiast boards can take 4 dimms.
Four ranks does have better performance, but limits your upgrade options.If you'd like four ranks, your best option would be two 16GB sticks.
^^ why would anyone sane put 4x4GB in a new computer ? more sticks = more stress on memory controller, lower frequency/higher timings.
as for this kit, CL16 is a bit too much for my taste for 3200 single rank 2x8GB kit.
Four ranks offer improved bandwidth and outperform two ranks in our charts, even when the timings are slightly worse. I think it's because a transfer on one rank can be initiated while the other rank is finishing a transition (such as read-to-write).
3200 C16 is our current performance-memory baseline. We just did a set of 3600 C19 and mentioned that we'd have preferred it to have been C18 or less.
It's more stress on the memory controller, but more performance out of the memory. DDR4 has a new feature called bank groups that DDR3 and prior lacked. It provides for better burst access speeds. It also has twice as many banks as well which can be accessed in parallel.
"On the other hand, the middle of the enthusiast memory market (currently, memory rated DDR4-3200 to DDR4-3600)"
If DDR4-3200 & DDR4-3600 is considered to be "middle of the enthusiast memory market" then what is the DDR designation for high end memory?
The entire Enthusiast market is high-end compared to other markets. You have DDR4-2400 through DDR4-2800 at the bottom and DDR4-3733 through DDR4-4600 at the top. Now that 2400 and 2666 have been standardized by JEDEC, "better than standard " at those data rates requires something like enhanced timings.
