Returning the RAM-kit. The shop tested it and it worked fine for them. They claim they tested on a x570 board with a 3600X. I recently upgraded my gaming rig's memory to the Corsair Vengeance RGB PRO 16 GB kit (2 x 8 GB) DDR4 3000 MHz C15, and I'm absolutely thrilled with the results. This kit delivers on both performance and aesthetics, making it a perfect choice for enthusiasts and gamers alike. Customize dozens of preset lighting profiles, experiment with a huge variety of user adjustable colors and adjust LED brightness to perfectly match your system. XMP 2.0 SUPPORT: A single BIOS setting is all that’s required to set your memory to its ideal performance settings, for for optimum performance. VCORE SOC Voltage set to v1.028 - Could not set to v1.025 as suggested as it seems my BIOS only has .022 and .028 options :(

My online research has found till now that everyone with hynix chip (RAM version 5.39) have the Intel optimized(B) module while those who owns the samsung b-die (RAM version 4.31) have the AMD Optimized(Z) module. CUSTOM PERFORMANCE PCB: Provides the highest signal quality for the greatest level of performance and stability.It may be that the CMK16GX4M2B3200C16 (Optimized for Intel) is using the less expensive and worse hynix chips (they have problems with AM4 but works good with Intel) while I suspected this was to do with overvolting of RAM or SOC initially when I faced many BSOD's (more than 2 per day), as I realised my BIOS VDDG and VDDP was higher than normal (1100 and 1000) when comparing to the Ryzen DRAM calculator 'Safe' values which were recommended at 900. As per another thread, I used Thaiphoon software to read the XMP directly from the kit before importing it and using 'Calculate Safe' option on DRAM calculator. This was stable up until this morning, despite several days of it working fine and 600% scope in MEMBench from DRAM Calculator 1.7.3 returning no errors! I specifically want the samsung b-die version (the Vengeance cost ~170€ while others ram modules like G skill Flare X or other modules with samsung b-die chip usually costs 200€+).

Running stable on 10c with Win 10 v1909, overnight MemTest86 showed zero errors. Edited November 13, 2019 by RBurgundy Issue is that I can not get my system to run stable when I enable the XMP in BIOS. System runs great at 2133 but as soon as I enable XMP to get the 3200 speed I get random BSOD, sometimes when powering down or when watching YT. MemTest86 shows well over 200 errors after only 2 minutes! I'm sorry to revive an old thread but i'm investigating the issue and I have a theory that i could not confirm or discard as invalid.

If you're building a Ryzen machine, it might be a better idea to get CMK16GX4M2Z3200C16. I'd recommend just getting a 2x8 kit and running it in Dual Channel mode. This was me and I wanted to share my experience too, since the problem seems to more widespread than just me.
