  • How to install 4x8 GB and 4x16 GB TridentZ on Asus X99-AII

    Dear experts,

    when I got the MB I couldn't find 16GB RAM modules. So I started with 4x8GB F4-3200C14Q-32GTZ.
    This kit was running fine at 3400 MHz (actually 1700, double data rate)

    Later I needed more RAM and bought another 4x kit: F4-3200C14Q-64GTZ, which is also on the QVL from ASUS now.

    What is the best way to install these modules?
    At the moment I have the 4x16 modules in A1, B1, C1 and D1 and the 4x8 modules in A2, B2, C2 and D2.

    But so far I only managed to run the RAM at 3000 MHz.
    I had to increase the current rating for CHA/B and C/D from 100%. Didn't start with the default. Currently using 140%

    Is this the best configuration in terms of performance and stability, or should I e.g. use: 4x16GB in A1, A2, B1 and B2 and 4x8 in C1, C2, D1 and D2 (or the other way around)?

    I understand that ideally I should have bought a 8x16GB kit, but I didn't want to throw away the existing 32GB RAM.

    You have it correct, one kit is A1 B1 C1 D1, another in A2 B2 C2 D2

    Try boosting DRAM Voltage and such values to see what higher values can be stable.

      Thanks a lot.
      So my assumptions were right :-)

      What voltage is still considered safe for these modules without destroying them?
