Do I need D.O.C.P

[RokenPrice]

I've been going through a hard time with machine. Ryzen 1800X and between (read on) 16 Gb and 32 Gb of Corsair Vengeance 3000 RAM.

 

After two house moves, she started playing up, and everything pointed to MB issues, especially when the LAN just gave up the ghost (this was a ROG-Strix B350-F Gaming), so I invested in a B450-Prime. Rebuilt, and hit stability issues when using D.O.C.P. I'm back to 2133 and things seem stable, though I have not (with either MB) been able to use 4 sticks 8GB RAM (All same make and spec). 3x8Gb works, and without DOCP, seems pretty stable.

 

Not much of a gamer (Trackmania via wine on Linux is pretty much it), but I am a 3D hobbyist (Blender).

 

Am I really going to notice the difference between 2133 and DOCP for my usage?

Running 4 sticks with zen 1's subpart imc and at 3000 is quite a bit of pressure on it.

you could set the soc to 1.15 and dram to 1.35 and then go for 2666 with docp and then go for 2933 and then 3000 and check stability.

Depends, some workloads will benefit and others wont, you can check how your workload gets affected by certain memory speeds and timings. 

but you can try what i said above.

You might need to enable DOCP, then manually drop the RAM frequency to DDR4-2933 or DDR4-2666.

As @TofuHaroto mentioned, 1st Generation Ryzen does not have as a robust Integrated Memory Controller (IMC).

It will be harder to get DDR4-3000+ running stable, especially with 4x DRAM modules.

Thank you. I'll spend some time tomorrow (I'd already dropped to 2933) dropping and seeing how it goes. If all else fails, I may just see how all 4 sticks get on at 2133, or may even underclock the RAM. Given this is not a gaming rig, it will probably not be as much as an issue for me as it would for gamers.
