    Z390-F & 4266 MHz RAM 2x8GB


    I can't succeed to POST at 4266 MHz but at 4100 MHz only. I have tried to ioncrease the voltage over 1,45 Volt, but probably not more than 1,46 Volt, and, I know that the maximum allows to 1,5 Volt.

    The kit is from Corsair, the Vengeance RGB Pro: CMW16GX4M2K4266C19 and they are 2x8 GB.

    I have also overclocked the CPU with the "AI" Auto OC. The CPU VCCIO is at 1,4 V and the SA at 1,4 V and this seems too high, but, this did not crashed or anything at 4100 MHz, I have asked Asus to add this kit of ram to the QVL in a next BIOS update.

    Why advertising a support of 4266 MHz ram while it cannot? Just only those G Skill ones who are 4x8GB each...

    Do you have any other ideas ?

    The CPU is a i9-9900K

    I have suceeded to POST on my Z370-F a 4000 MHz RAM who isn't QVL (same corsair ones) and all I had to do is to increase a little bit the RAM voltage, but, here, I wonder if I should go near of the 1,47 to 1,50 V ?
