Since I was never able to achieve stable 4200MHz for all cores on my Ryzen 5 3600, I tried numerous variations to get that stable and was unable to no matter what I did, so at first I thought that the CPU overclock(CPU was overclocked using PBO at that time) was the problem. I was quite confident that the memory was stable as it passed Memtest86 quite a few times with no issues and I was not expecting the problem to be caused by the memory, so I checked if the issue is hiding there for last. Generally it is not recommended to mix two different ram kits since you may have compatibility issues. still not able to post when i edit the settings , will give it another go at some stage , i followed paridoth setttings , but im still new to overclocking and i must be doing something wrong . Unless you're overclocking, or using an Intel platform with XMP profiles, it probably doesn't make too much of a difference which one you get (though I've heard Ryzen can be picky with the type of memory it can accept).

Corsair Vengeance LPX Black 32GB 3200 MHz AMD Ryzen - Scan

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. As I said, just use the export option in Thaiphoon and make a html page of the full results of the read.

I believe it has something to do that the CMW32GX4M2C3200C16 is optimized for Intel and that maybe there is an issue with the XMP, that the values don't work with an AMD system.

VENGEANCE® LPX 32GB (2 x 16GB) DDR4 DRAM 3200MHz - CORSAIR

And of course it turned out that I had no stability issue with nor CPU or GPU(GTX 1070 FE I have for a long time and I know what this card's overclock potential is). My goal right from the moment I upgraded my system was to achieve fixed 4200MHz stable on all cores for the CPU and 3600MHz for the RAM.I wanted to ask which version of windows you use, on which version of AGESA you managed to achieve stable operation, and did you overclock your system?
