I like how it says: "Good luck!" AMD knows getting RAM to click on AM4 is a pain in the *** and it often does come down to dumb luck.
Eh? I haven't had any problems. Maybe it's just my 3200 CL14 Sammy B addiction.
It says "Good Luck!" in regards to hitting 3800 (1900 FCLK), which on the new platform is supposedly 4000 (2000 FCLK).
I can
run 1900 FCLK on my board/cpu, but because my power delivery situation is poo - someone turning on the oven, or a vaccuum cleaner, makes my system go boom-boom.
The "expected" FCLK overclock area is 1833-1866, occasionally with 1900 (1933 exists as a unicorn witnessed once upon a blue moon)
Thus the expected FCLK range for Vermeer is likely to be around 1900-1966, occasionally up to 2000 - maybe with more unicorns, maybe not.
pro tip: test performance scaling of fclk, you might screw yourself inadvertedly with HIGHER = BETTER
here's a few memory recommendations (not necessarily from the exact sellers listed on this website, just the memory kits in general)
Cheap dual-rank Micron E, will clock up but won't have nice timings. Fortunately, it's dual-rank - so that's not a gigantic problem.
The
slightly more expensive 3600 MT/s bin might have slightly better timings, I couldn't tell you.
Hey look, it's the 3200 CL14 dual-rank Sammy B I bought!
Might not clock up to high frequencies, though 4000 should still be pretty reliably possible, and the timings are good.
If you wanna play it safe, then here's another dual-rank Sammy B kit that will consistently hit high frequencies - might even time a little better if you're lucky.
If you're wondering why they're all dual-rank, then it's because The Meta™ has evolved and we've embraced that dual-rank is Just Better in a frequency-restricted environment.
