    I really want to know what the wartning is at the end of the blog. Sounds nasty.

    Within the table it says:
    Added dividers for memory clocks up to DDR4-4000 without refclk adjustment. Please note that values greater than DDR4-2667 is overclocking. Your mileage may vary (as noted by our big overclocking warning at the end of this blog).
    Apparently anything more than DDR4-2667 is overclocking which is a little odd. If your RAM is rated at 4000 and your system has the physical option adjust it to that provided by the manufacturer I'm sure it can argued that it's a function provided as is. So therefore if your system were to break when setting that manufacturer provided setting and they didn't replace your goods I bet it could stand up in court.

    You don't provide a function that can damage your cooker that a user can easily use?

    Re: AMD's AGESA v1.0.0.6 for overclocked RAM discussed

    Isn't it the usual to state the native speeds and higher speeds are overclocking, looking at Z270 boards they say the same.

    This is only good news, just hoping this leads to 64gb at 3000mhz being possible for my next build.

    The ram may be specced to run faster, but faster ram puts more stress on the memory controller in the CPU. The memory controller is only specced to run the ram at up to 2667.

    I guess we're getting it, warts and all

    Guaranteed 2.7GHz pretty high for a memory controller - the 7700K only goes up to 2.4GHz

    Re: AMD's AGESA v1.0.0.6 for overclocked RAM discussed

    It's normal to see this caveat. My board is an old P7H55. It goes up to 2200 but anything over 1333 is overclocking by raising bclk or the memory multiplier to get there. My CPU max official support is 1333, but the memory controller will happily do much more - as advertised in the mobo specs.

    eg I'm sat running 2133 rated RAM at 2160MHz without any tweak to the RAM voltage, just upping BCLK, vcore and the RAM multiplier. The native cpu bclk is 133MHz, I'm at 180MHz, for which I've had to up Vcore and IMC voltage to get it stable. The RAM defaults to 10x multiplier by preference, but the CPU integrated memory controller offers 6x,8x,10x,12x options. So 12x180 = 2160MHz. I could apply the offset adjustment to 0.495x instead of the default 0.5x per channel to make it 2133MHz, but the RAM is stable at 2160MHz so why bother?

    If you can run faster RAM by only adjusting the RAM multiplier eg mine would run at 12x133 = 1600MHz without any boost to BCLK or Vcore etc, then it wouldn't be overclocking the CPU, but if you have to up BCLK, Vcore or Vram then that is defined as overclocking the CPU/chipset.

    (NB even selecting XMP profiles for RAM would automatically adjust bclk and overclock the CPU to achieve this.)
