    been reading about that for a few days thrash. Seems the FE versions are most problematic at this point. See how it goes. Got the block on now so that should help.
    You are good @doorules they have dying cards because they gave up when they heard you have one now

    According to a thread on Silicon Lottery, the only 370 board to make their Qualified Vendors List for the 9900k chip is the ASUS ROG Maximus X Apex
    Attachment 210380

    This is because of the way the core voltages are reported by the chip that measures it, not because the boards are not good overclockers. The X boards (Apex excepted I guess) measure the core voltage too high under load, and the higher the load, the higher the voltage is misreported (too high by 0.1v even). So for the 9900k and 9700k, which have 50% more load, the voltage reporting is inaccurate enough that Silicon Lottery doesn't want to deal with users complaining that their 1.4v binned chip (binned on an XI system) is only stable at 1.5v on the user's X board.

    The XI boards measure core voltage more accurately (lower than X boards under load).

    So keep this in mind when you are comparing OC results between the XI motherboards and X motherboards. The reported core voltages under load are not directly comparable. It depends on the load line and loads, and what may look like a better core voltage on an XI board may actually be worse than the X board.

    Yes and I posted those results, fact still remains that the ONLY 370 ASUS board that Did NOT need the voltage set higher was the Apex X .....That is why all the other Asus boards did not make their QVL list.


    Here is the question from a user, and the Answer from SL


    Question that was asked:
    How do the 370 Maximus boards hold up to 9700K/9900K? I notice the APEX is there, but the rest are omitted, which is curious to me seeing that, as far as I can tell, the power delivery capabilities are roughly the same, just that 390 has more efficient VRM.

    Answer from Silicon Lottery:
    The way they measure core voltage under load is too far off other motherboards, so they didn't make the QVL this time. You would need to set a higher voltage than we tested with to match our results. Apex isn't affected as much.

    Still it does look like to run the 9900K with the better VRM's, for the Best cooling, we would need a Asus 390 board.
