    My 790 APEX can do A-DIE 8800 boot on air by gear2 mode, but failed to same 8800 by gear4 mode. Have tried different CPUs and BIOS but nothing better, any idea? :(

    Which bios? I think it only works on certain bioses from what I have seen people say and also needs lower voltages from what I remember.

     

    I think one of these newer ones that it worked on 0078 or 0088. Not sure.

    Installed that unofficial 2301 and now stucked to it, it won't let me to downgrade to any previous version anymore, please advise !

    Thanks.

    I have seen others on OCN say you cannot flashback to older bioes once on 2301. I would have thought they would have made note of that as all the people that complained when they did the same with bios 2004.

     

    ROG MAXIMUS Z690 APEX BIOS 2004

    Version 2004
    10.8 MB

    "1. Improve system performance
    2. Update ME version to 16.1.25.1885v2
    3. Many ME updates and optimizations for the next-gen CPU are included. This version does NOT allow rolling back to the previous versions, not even via USB BIOS FlashBack™, to ensure better compatibility.

    I have Z690 with 13900k and just got my Z790 yesterday. You want the SP score that is listed for both the Efficiency cores  and the performance cores in the AI menu, right?

    I was curious about MC SP. I compared the CPU SP and they were the same for me on z690 and z790 Apex. But when I had the 13900k in z690 Apex the bios didnt have the MC SP yet.

     

    Info from Shamino

     

    "MC SP

    --------------------------------------
     
    • Tests the MC solely, without touching the DRAM (you can even remove the dram while its testing) , same mc on different boards/dimms should give similar score
    • Tests the FMax of an MC at a fixed low SA voltage. In the same way you test a core's fmax at a low voltage idling.
    • Since there is an element of luck when testing FMax like you would when running for a cpuz record, the outcome will not be 100% the same everytime and score will shift a little.
    • Temperature affects FMax but the effect is weighted and the maximum package temperature during the training is taken into account to generate an unbiased score.

    there is a strong co-relation between MC FMax and DRAM OC just like Core FMax with Core Cinebench Freq.

    a sample from a not so good board , no so good dram at 1.4v by a not so good overclocker (me!):

    in other words, all things remaining the same, there is a high probability that a higher mc sp will net a higher dram oc.

  4. Posting in case anyone else runs into this issue on Strix d4 with 13th gen.

    I had 12900ks installed flashed from 1601 to 2103 and it was like I had a really bad IMC gear 1 after installing 13900k, it would not be stable for memtest or y cruncher. Current ME firmware(1917) was installed before installing 13900k

    So I flashed back to bios 2004 and then to 2103 and now it is stable in gear 1 4300 with DR b die.

    Just wanted to let anyone know if having issues on Strix d4 try that.

    Edit used Ezflash for flashing for info

    Hi! it's your daily profile? Can you share the .cmo please?

    Here is the cmo. cpu is at default. https://1drv.ms/u/s!Alekwwtstb8wlOJOPvNz6ssFJv7XqQ?e=Avf6LJ

     

    I usually set static vcore and p,e and cache for daily. Unless you have really good sticks you will probably need to bump dram to 1.563 or higher to run 4266 or lower ram clock to 4133c15-15-15.

     

    Edit I noticed I had tras set to 16 in that cmo. It will probably be easier to boot and get stable at 30 to 36.

    Thanks for the valuable information.
    I'm considering buying one set of DDR4.
    Do you have any recommendations?

    Do you want SR or DR?

     

    I have only bought DR in the last year or so and have bought most of the top bin b die and I think for the money the 4000c16-16-16 kit is a really good kit. OC really well. But any of them are lotto/luck.

     

    If money is no object the 4000c14 kit in SR and DR is tops and for SR 4800c17 kit is good but pricey.

     

    Also it could be your IMC. Not sayin getting different memory will let you run 4266.

    Unfortunately, BIOS 901 did not work.

    Then I would try 707, 812 and 808 also worked good for me on SR.

     

    If they dont work it could be an issue of the memory and z690. I know someone else who has a Galax HOF 5000c19 memory kit and he can not get it to work well on Strix d4 or MSI Z60 d4. I think he struggles past 4000.
