Since the FCLK is up in the air for the Matisse 2 refresh and Zen 3 FCLK is unknown, it doesn't make much sense to buy a B-Die kit for running XMP atleast until August/September gives us a good indication. What timings are people running these at for 3,600 and 3,800? If someone can upload the Taiphoon profile to mega.co.nz or google drive I'd like to fiddle with it in the calc.
 
Thanks that worked. For 3800 it gave me 16-16-17-16. I'm shocked it suggests 1.42 and not 1.45 to squeeze more out. I also find it interesting that 3733 is recommended C14 but going to 3800 makes it go to C16 tf????

The 4000 preset is also primary C16 so these look like a solid purchase for the future.

Its a calculator, designed to give you values that'll almost certainly work as long as you input the right information. Your specific RAM may be capable of more, but its up to the user to then tweak further should they want to. Use it as a "safe" baseline.

This is what I run on my Patriot memory in 4x8 config 3733 14-15-15-30, any higher frequency or lower timings spits out errors.

My Infinity Fabric tops out at 1866, anything more and it's unstable.

That's at 1.45v, so it may do more, but it's more than enough.
 
Thanks all. If this RAM gets popular come Matisse 2 refresh I'll update the OP with all community timings at different speeds.
