Hi, I wanted to know what Ram timings you use to get the most performance out of your Ryzen 2700. I did buy some more ram chips 2666 I believe, (32Gb now) but I see that it only supports 2400 speed? 

If possible, can I get screen shot of your Ryzen Master settings please, I think I screwed some of the ram timing numbers, and it's stuck that way now. I can't change it to back to defaults. I believe I uninstalled Ryzen Master, and the Ram was still set wrong and there are quite a few choices other than the main ram timing numbers.

    First off, just so you are aware, this link has a chart showing how the CPU sets the RAM speed:


    What it really boils down to is if you have single rank or dual rank RAM.  If you've got two sticks of dual rank, you'll be looking at 2400, which is where I'm sitting.  If you've got two sticks of single rank, you can get that 2666 speed. 

    For my Ryzen Master settings, I'm at 2400mhz, can't get any higher.  As for my timings, and your mileage may vary wildly depending on your individual RAM SoDIMM's, I'm running 16 cas latency (matched for all other settings not listed), 32 RAS Active time, 48 row cycle time, 12 cas write latency, 60 ohms.  These are my current settings I've found to be stable, but haven't messed around much to see what I can get.  My current RAM is 2 sticks of 32gb (64GB total) Hyper X Jedec 2666 set.
