Any suggestions to why the memory is stuck at 1866MHz, The task manger shows that the memory sits at 1866Mhz. I currently have 8GB x 4

Solution
I would expect that there is a chance that two sticks may work at 3200MHz if your memory is are F4-3200C16D-8GTZR. The reason that I say that is your board is on the G.Skill QVL for F4-3200C16D-16GTZR (the 2 x 8GB set). Which 2 hard to say as they are tested in sets, but at least you may get lucky.

Beyond that I doubt it because all of the qualified 32GB sets that were similar are 2 x 16GB.

The 32GB set F4-3200C16D-32GTZRX (the AMD optimized 2 x 16GB model of that memory at 32GB) only lists the Gaming 7 as supported; same story for the F4-3200C16D-32GTZR.

I've seen a lot of similar situations and the usual result was that 4 sticks would run at 2133MHz.

No, all your sticks run at the same 1833MHz DDR speed. You're confusing it with your CPU idle/base/MC boost/SC boost clocks.
Make sure your BIOS has a XMP profile selected. Don't be surprised if your RAM doesn't get past 2400/2666 MHz DDR because you're running 4 sticks and some motherboards don't allow the top speed profile to run in such a case.

Solution
Well, thankyou for all your reply's. I've finally sorted the issue. Loading the XMP profile I realised the 3000MHz was not possible even said advertised at 3000MHz, instead I lowered the frequency at each set speed.

At 2933MHz the computer booted and all was good, until every program started crashing. Back to BIOS...
At 2800MHz same problem.
At 2666Mhz same problem.

Therefore I hit an ultimatum at 2400MHz for the computer memory to be stable I believe. Talking DRAM Voltages and such.

For now I will run the memory at 2400MHz, however if the problem persists I will drop the frequency value to 2133MHz.

Thanks for the input, its very much so assisted the solution, anymore input would be much appreciated.

Did you only set the speed and not adjust the timings or voltage? I would retry 2933 at CL16-18-18-38 1.35v. Leave the other timings on auto just to see if it will even work. Then run memetest86 for at least 1 full default test pass.

You should be able to run 2933/3000 using the timings and voltage advertised (manually entered) for 3200 without issue on your X470 motherboard and Ryzen 5 2600. Just a suggestion, but I had to update my B450 motherboard to AGESA 1.0.0.4 B (bios F50 for your motherboard model), before my two 2x8GB Patriot DDR4 4000 kits would work with my Ryzen 5 2600.
