Hello! I used Ryzen calculator and I will optimize from there although I found some strange things like not even posting at any speed with the CL 16 timings that the ryzen calculator gave. I don´t know why is that, but anyway, it went very good with those cl 14 timings.
I agree with you that getting to know timings takes time (hahaha) and even more to tune memory properly. Just now I´m only making an approach to it, since I dont overclock anything since 775 platform, and I´ve forgotten all this memory stuff.
Micron E die is the cost per performance sweet spot (at least I see it that way) from what I´ve seen over the internet Samsung B die can do some amazing things, micron is not so good on timings given the speed in mhz, but it´s much cheaper... At first I was going to buy the best micron e die model, 3600 cl 16 I think, but it was 164 euros, and I could find some b die for just below 200... so I thought that it was a better idea to go full blast with a 200 bdie, save as much as I could and put that money into a 3700 x insted a 3600... and thats what I did. Don´t regret it to be honest.
Another thing, I think that memory perfomrance is not dependant on chipset but on the cpu itself with ryzen, so you should get the same or similar results. I could be wrong though, I´m learning along I do how this platforms work, so maybe mistaken in this regard
One last thing, my current config ir at 3466 mhz, since the last one was not completely stable. It crashed sometime at night during a memory stress test... I worked with those timings with no problem for two days, but just in case... I downgrade the speed a little.
