What's the point of having eight RAM DIMM's?

[lancer420]

This is a question I'm asking out of curiosity rather than requesting help. So, I've noticed that a lot of people on YouTube who have these overkill systems have eight RAM DIMM's in they're computers. Now, correct me if I'm wrong, but I'm pretty sure even the newest processors only go up to quad channel, so what's the point of having twice as much RAM? Thanks!

Quad channel memory:

High End Desk Top (HEDT) CPUs use quad channel memory which requires 8 DIMMs. H

Even if the memory does not run in quad channel, having 8 slots gives you plenty of RAM expansion for workstations, there are also systems with dual CPUS that have 8 slots, 4 for each CPU.

Here is a board with 16 RAM slots.

Mostly just for capacity, I think. DIMMs larger than 16GB are rare, so if you want 128GB that is 8*16GB DIMMs.

Of course, that much memory is totally unnecessary on a general purpose home PC or a gaming PC, but common on servers.

Ddr3, ddr4 limits on consumer grade ram is 16Gb per stick. That's assuming the mobo is built to accept 16Gb sticks, many can only handle 4Gb or 8Gb. To get 32Gb sticks, that requires a ECC/Registered capable server mobo, kinda rare for consumers to use. There's multiple programs in professional usage, like rendering, compiling, multitasking, virtual machines etc that benefit from greater amounts of ram, so 128Gb is not uncommon, requiring 8x slots instead of the traditional 4x slots, but that'll also require a cpu/mobo capable of handling not only the bandwidth but the channel configuration to field that bandwidth. As in x99 systems etc.
