I've seen (and must previously have ignored) warnings on memory vendor's sites
(e.g. mrmemory.co.uk) that you can get a 10-15% performance boost by matching
memory modules in pairs. My PC has 18GB of RAM (used to be 2x8 + 2x4 until one
of the 4's conked out). Would I see a performance increase either by replacing
the missing '4' or by removing the remaining 4? Peak Commit Charge never goes
anywhere near 16GB in normal use.

Nothing you'd ever be able to tell, outside a benchmark. IME it's more
in the 4-8% range.

A bit like fast RAM, all DDR4 is 2133mhz then these fast RAM speeds of
3600mhz and such like are all overclocked albeit stably.

I bought a pair of some cheap at the time DDR4 16GB 2133 sticks two and a
half up years ago and have it running at 2400mhz.

You’d never be able to tell the difference between 2400mhz and 3600mhz
outside of benchmarks in day to day use.
