Just out of interest, I've got 1596Mhz of ram showing on my Speccy tool CPU-z abou the same. I have 2x 8GB of 3200mhz DDR4 ram. Is this right?

Qazzy03: Yup that is right.
Speccy is showing speed of each individual ram stick when you double it.
It gets to be about 3200 MHz.
So half is about 1600 MHz ish.
Oh yes, of course. Is there a way to test how much ram is being used at any given time when playing a game etc?

Strictly speaking it's not due to each individual ram stick, it's because DDR means double data rate, and speccy is showing it before it is doubled

Also, while the RAM says it is 3200MHz, it is actually 3200 MT/s and 1600MHz, with MT/s meaning mega transfers per second

Yep, look into MSI Afterburner and RivaTuner Stats Server.
You can configure a lot of on-screen-display options while playing games. Pretty much any CPU/GPU/RAM statistics you want to display can be shown with this.

Technically, yes. It's a throwback to the SDRAM days (before DDR).
~3000Mhz = effective transfer rate (speed) since DDR performs two transfer per CPU clock.....vs SD RAM (one per clock).
Anyway SD is ancient history so just double it. :)

I use Process Hacker but if you open Task Manager/Performance/Memory - look at the Committed amount.
With WDDM 2.0 DX11/12 system memory can be reserved for the GPU..... it may not show as being in use but won't be accessible to the CPU.
Interesting... I have "G.SKILL Trident Z Neo RGB F4-3600C18D-16GTZN 16 GB RAM (2X 8GB) DDR4 3600MHz" and CPU-Z is showing 1041MHz. That doesn't look right... assume I need to go into the BIOS and tweak something? I had a poke around in there, turned on XMP, couldn't spot what to change. Any tips?

Your RAM is running at official JEDEC specs, you'll have to adjust it manually, don't use the auto XMP setting it never works properly.
fwiw AMD boards don't support automatic XMP profiles, they have a submenu that shows XMP timings but it's a manual affair. :)
Just note the timings, speed and voltage and change them manually if no bios option exists.
*And raise the voltage to 1.35v.

Oh, interesting. Any tips or tutorials for how to do this? I'll try Googling later on.
I don't want to break the computer. I've never done RAM settings manually, always had Intel before which "just worked".

It's been years since I owned a Gigabyte board so I can't be overly specific on where to find everything however the first change you'll need to make is the DRAM VOLTAGE setting - under the Advanced Menu from AUTO to Manual. Then punch in 1.35.
I think the voltage might be the problem as the other timings look OK. It should be 1.35 but right now it's still 1.2

In the BIOS, on the right hand side, it already says the voltage is 1.38v with frequency 2138MHz, so that would be lowering it. Seems like it's in an odd position, doing XMP voltage but JEDEC speeds. Any thoughts?
Specs say:

Specs say:
- Tested Speed 3600MHz
Tested Voltage 1.35V
SPD Speed 2133MHz
SPD Voltage 1.20V
Yes I noticed, however on the left beside DRAM Voltage it reads 1.20v.
