    I have a friend who lives in Australia asking me why his G.Skill Flare using Samsung B-Die DDR4 3200 is maxing out at 2933 supposedly.

    Are you supposed to enable XMP, disable XMP and manually set speed and timings, or what? He has an MSI X370 Carbon board and a 1700x.

    Are there any other relevant settings in the BIOS that meed to be changed to get the memory to 3200MHz? He said he flashed to the newest BIOS as well. Im sure i could figure it out if i was there but i live in the USA.

    Isn't xmp Intel specific? Or am I out of date here? Set timings manually and check whether his ram is on the compatible list for the mobo.

    3200 has been stable for many from the get go. Now it's just stable on pretty much everyones machine with updates. And people get towards 4000 with tweaks.

    Is the ram double sided? Does Thaiphoon Burner say it is single or double rank?

    Have set my timings manually. DOCP just does not function in the way I think it should. Does not set all the timings from the profiles. It does the majority. Trfc needs to be set manually. At least this is how it is on the two ASUS boards have used.

    If he just pops up the editor in Thaiphoon Burner, it will tell him what the values should be for all the secondary and some of the tertiary timings. After writing them down just check to see how the bios sets them or just enter all those timings in manually. AGESA 1006 should have made those plug 'n play.
