I would like to know the opinion of experts on some issues regarding the choice of RAM, as well as about her work in Quad-channel mode.Motherboard:X299 MSI SLI Plus
supports Quad-channel mode.RAM (for example):Corsair CMK16GX4M2B3200C16 (3200Гц, CL 16, 2x8Gb)
— 6010₽Corsair CMK16GX4M2Z3200C16 (3200Гц, CL 16, 2x8Gb)
— 5350₽Corsair CMK32GX4M4Z3200C16 (3200Гц, CL 16, 4x8Gb)
— sold out, presumably 19000-23000₽
Main question: is it worth buying a set of four laths on 8Gb or you can purchase two identical sets, each of which will have two straps with 8Gb (it is much cheaper) — will it work in Quad channel mode? If not, how significant the increase is the use of four-channel mode vs dual channel?
Because socket2066 implies a restriction of DDR4-2666, as I understand it, any memory frequency above 2666Гц will work on this frequency?
I will be grateful if I could clarify the difference between the two absolutely identical models of memory 2x8Gb above: CMK16GX4M2B
3200C16 and CMK16GX4M2Z
3200C16. From what I could find online, and letter "Z" only indicates that the memory was released later, apparently in connection with this it is cheaper?
Thanks in advance for your answers.
