Well here's some good news A Computer Guy: BIOS update for my board last night, I'm now running all 4 of my Dominator Plat RGB with DOCP active, 3133MHz and appears to be stable. 3200 hard locked the machine when I ran a game. That's the best speed I've seen though, better than the previous 3000 I was getting.

Spoke too soon. Ran stable all day just web browsing. Played Destiny a while and the game kept crashing, then the system. Backed off the speed to 2800 and stable while gaming again.

Have you seen this article? It really helped me last time around.
"AMD Ryzen Memory Tweaking & Overclocking Guide"
https://www.techpowerup.com/review/a...locking-guide/

Also something I noticed last time when troubleshooting Ryzen Timing Checker doesn't seem to work quite right anymore perhaps because of the newer BIOS/UEFI updates.
For example the timings seem correct but ProcODT, RTT, and CAD_BUS options don't match what I set in the BIOS/UEFI.

Thanks for the link, did some research there and spent some time with DRAM calculator for Ryzen after pulling all the RAM info with Typhoon. Currently I've used all the settings the calculator gave me and slowly pushed it up to 3000 and things are running good so far, no blue screens or lock ups. I'll probably push it even further over the weekend to see just how far I can go and keep it running stable.

Ran the system a whole day at 3066 and it was stable even through a marathon gaming session last night so this morning I pushed it up to 3133. Tested with playing a game and had no problems. Will keep it at this speed for today to confirm stability then push it to 3200 tomorrow.

So far here are the best timings I managed to get with my RGB memory kit.

This got me a score of 113% on UserBenchmark.com.

The best score I got was 114% at 3266 however after another BIOS update to P3.30 that frequency became unstable so I had to back down to 3200.

Compared to many other users this seems to be near the top end score for this memory kit at 3200.
https://ram.userbenchmark.com/SpeedT...3200C16-2x16GB

Hopefully this will be helpful to other Ryzen users with this memory kit trying to get the best out of it.

Code:
CMW32GX4M2C3200C16 (ver 4.32)
DDR4-3200
 18 - tCL   (from XMP 16+2)

New timings that should work for with a Ryzen 7 3800x.

Currently testing these timings....working w/ BIOS/UEFI P3.30.

Code:
CMW32GX4M2C3200C16 (ver 4.32)
DDR4-3200
 18 - tCL   (from XMP 16+2)
 17 - tRCD  (from XMP 18-1)
 17 - tRP   (from XMP 18-1)
 36 - tRAS  (from XMP)
 58 - tRC   (from XMP 54+4)
  6 - tRRDS (from XMP)
  9 - tRRDL (from XMP)
 34 - tFAW  (from XMP 36-2)
  4 - tWTRS
 12 - tWTRL
 12 - tWR
  4 - tRDRDSCL
  4 - tWRWRSCL
512 - tRFC  (down from 560) 
380 - tRFC2 (down from 416) 
234 - tRFC4 (down from 256) 
 18 - tCWL
 10 - tRTP
  6 - tRDWR
  3 - tWRRD
  1 - tWRWRSC
  7 - tWRWRSD
  7 - tWRWRDD
  1 - tRDRDSC
  5 - tRDRDSD
  5 - tRDRDDD
  8 - tCKE

DRAM = 1.35v
SOC = 1.012v (SOC OVERCLOCK VID = 54, did work with AUTO as well)
SOC now located in Advanced/CBS/NBIO/XFR
Gear Down Mode = Enabled
Power Down Mode = Disabled
BGS = Disabled
BGS-ALT = Enabled
ProcODT = 60 ohms
RTT_NOM = RZQ/7(34)
RTT_WR = RZQ/3(80)
RTT_PARK = RZQ/1(240)
CAD_BUS = All 24 ohms
tCL still won't budge, can't seem to knock it down to 16
tRC still won't budge, can't seem to knock it down to 54

(Score with this memory was better with Ryzen 5 2600, this score with Ryzen 7 3800x is lower)
Up to 93.7% https://www.userbenchmark.com/UserRun/18560160

Had a surprise with ASRock BIOS/UEFI version P3.40 w/ AGESA 1.0.0.3AB.

I was able to bump up from 3200 to 3600 (couldn't do that before) so there seems to be an improvement. UserBenchmark went up from 93.7% to over 100%

(...still working on trimming the timings below...will edit when finalized...)
(...updated 7/29/2019...)

Code:
CMW32GX4M2C3200C16 (ver 4.32)
DDR4-3600
 18 - tCL
 19 - tRCD
 19 - tRP
 42 - tRAS
 68 - tRC
  6 - tRRDS
  9 - tRRDL
 32 - tFAW
  4 - tWTRS
 12 - tWTRL
 12 - tWR
  4 - tRDRDSCL
  4 - tWRWRSCL
560 - tRFC
??? - tRFC2
??? - tRFC4
 18 - tCWL
  6 - tRTP
  8 - tRDWR
  3 - tWRRD
  1 - tWRWRSC
  7 - tWRWRSD
  6 - tWRWRDD
  1 - tRDRDSC
  5 - tRDRDSD
  4 - tRDRDDD
  0 - tCKE

DRAM = 1.35v
SOC = 1.1v (with AUTO)
SOC now located in Advanced/CBS/NBIO/XFR
Gear Down Mode = Enabled
Power Down Mode = Disabled
BGS = ??? could not find setting with new BIOS/UEFI
BGS-ALT = ??? could not find setting with new BIOS/UEFI
ProcODT = 60 ohms
RTT_NOM = Disabled
RTT_WR = RZQ/3(80)
RTT_PARK = RZQ/1(240)
CAD_BUS = All 24 ohms
The new Dram Calculator 1.6.0 doesn't seem to work in my scenario. It won't calculate DDR4-3600 settings says "not supported".

Up to 104% https://www.userbenchmark.com/UserRun/18880711

Using AIDA64 going from my previous DDR4-3200 to DDR4-3600
read improvement +5,580
write improvement +3,391
copy improvement +5,386
latency from 77ns down to 71ns

I don't have any data to compare against. If someone else out there has a 3800x and this memory kit do you get similar results?

What do you know, perfect timing
