I'm still waiting on my CPU Cooler before I can start 
Asus ROG X570 Crosshair Dark Hero Release? *** NO Competitor Talk ***
My board displays the "FF" Debug code (which helpfully seems to mean "Fault Found") after booting to Windows. No idea what the issue is, but everything seems to be working fine. Would be interested to see if anyone else gets this error code though.
Also my board wouldn't boot with 4x8GB sticks of RAM initially. Had to enter the BIOS with only a single stick and set the DOCP profile (3600MHz, C16). Then shutdown, inserted all the remaining sticks of RAM and everything was fine.

5900x, 32gb, 3080, dark hero
Cinebench R23 -
Multi - 20881
Single - 1621
so not a lot of difference between our scores. System is stock no overclocking on any parts
Okay then, I had just been looking at https://www.cpu-monkey.com/en/cpu-amd_ryzen_9_5900x-1748
Where it suggests an average score of 21878, and I'm a good bit shy of that, my friend has a 5900x in the Formula x570 board and got 21138 , so because I was a good bit under the 21k I was just starting to wonder if ive a low clocker
However I did just see a reddit post about someone disabling the dynamic oc feature on our mobos as it may actually impact scores
I've just finished running the benchmark again with that feature disabled and my new scores are
Multi : 20901 - still under 21k but a decent boost
Single : 1622 - small improvement but could just be margin of error

Your RAM is @ stock speeds?
Mis-read my bad lol
current ram set up. i've not even gone into the bios to make changes after the problems i had getting things started last weekend. As you'll see ramr bandwidth set at 2400, whereas ram speed is 3600

I decided to check my ram bandwidth and it is the same as yourself, 2400 max bandwidth but my ram speed is 3600, for the uninitiated - does that mean my ram isn't reaching its full potential?
wishing i'd bought 2* 32gb now and not 4 * 16gb. Don't think I can return it now as i've used it in my set up. Bought from overclockers so don't know what their returns policy is on this
Hi
Why isn’t this ideal out of interest? I ask as I’m aiming to build a 5900x / Dark Hero combo when parts become available. I was currently thinking of 4x8GB sticks of Corsair LPX (needs to be low profile). Would I be better going for 2x16GB instead? If so, please can you explain why if possible please. I’m pretty much set on Corsair Vengeance LPX by the way unless you guys know of any other low profile, black heat shield RAM.
I’ve been trying to get my head around channel, rank and speed and thought I’d come to the conclusion that 4x sticks of 4GHz RAM would be optimal but I onlyreally build every 5 years or so so I’m very out of the loop, especially at the higher end of specs.
Thanks in advance.
I am not sure as I've been out of building pcs for a long time but I think is because 4 populated DIMMs put more pressure on the memory controller than 2 (which can lead to issues)

Most 16GB sticks (apart from Micron B die which is relatively new) are dual rank. Dual rank sticks are good in a 2 DIMM setup but Zen 1/2/3 can struggle to get high speeds with 4 dual rank modules.

8GB is normally single rank so you should be fine to go 4x 8GB but you might want to just double check.
Edit: 4x Single Rank DIMMs is normally fine and runs good, but if you got Dual Rank sticks you only want to run 2 otherwise you put huge strain on the memory controller and will struggle to run high frequencies.
I was tempted to get 4 sticks of that Micron B Die but its £315 for 2x 16gb 4000mhz. Feel like I'm better off waiting for Trident Z Neo 4000mhz 2x 32GB releases.
Got a old kit of 4x 16GB Samsung B Die 3446mhz to use as a temp thing, though I might be just running 2x 16gb of it if the memory controller really can't handle it.

I've got 4x16GB 3466mhz B die, did you get the same great deal on Corsair RGB stuff I did by any chance?
I really struggled with 4x16GB on my 3900/X570 Taichi. I've not tried running 4 sticks on my 5900X, but 2 sticks run great. Got to 3800mhz C16 no problem.
