    Hi everyone. I'm hoping someone can help me. I have the ASUS ROG mobo in the topic title (but no wifi) and it has been a nightmare for me. No matter what RAM I use, I can only get 2666 mhz out of it and if I try making it go any faster, even if it was designed to go faster, it bricks the PC. So I did research and came across this site's review of the mobo. It recommended G Skill FlareX 3200 CL14. I went and got 2x8 gigs worth of it. Installed it, set DOCP...nothing. Dialed it back to 2666 and it works now. -_-

    AFAIK, the mobo is physically fine and the RAM slots work fine. All my other components have been ruled out as suspects. I have the latest BIOS version for my mobo and I'm thinking that's the problem. Perhaps I need to dial back the BIOS. I guess this question is really going out to Hilbert Hagedoorn. Do you remember what version of the BIOS your test mobo had when you did the review? That just might solve my problem. Thank you in advance for the help! :)

    I’m assuming it’s a 400 series board and a 3K series chip. If so you’ll want to get a BIOS with AGESA 1.0.0.3

    not available yet, 2501 includes AGESA Combo-AM4 1.0.0.2

    Right but to get the proper operation it’s going to require them to post it.

    There are different versions of the Flare-X kit.
    I'm using a 3200 MHz kit which runs @ 3533 on the same MB using a Ryzen 2700X and BIOS 2501.
    There is no need to use DOCP it won't work. Just use the 3466 MHz Stilt profile from the bios
    and go from there or just start with the 3200 MHz profile.
    Don't forget to adjust the memory speed in the advanced tweakers section after you have selected a profile.
    The only thing you may need to adjust is the SOC. But start with the 3466 MHz Stilt profile.
    I believe there is also a 2400 MHz Flare-X kit.
    Can you post the exact model number of your ram kit ?

    Thanks for the quick replies, everyone. I'll try the Stilt profile and see if that works.

    Straight from Newegg:
    G.SKILL Flare X Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3200 (PC4 25600) AMD X370 / B350 Memory (Desktop Memory) Model F4-3200C14D-16GFX

    Well thanks to Stilt it's holding steady at 2933, which is at least a step in the right direction. Thanks again! :)

    Ok. That's a step in the right direction. But you should be able to do at least 3200 MHz without any problems.
    1. What CPU are you using ?
    2. What ram slots have you inserted the sticks into ?
    (Slot A2 and B2 is recommended for 2 memory sticks and can really improve Ram speed)
    3. What is your SOC value ?
    (You can use ryzen timing checker to see what it is in windows)

    its within expectation for the 1.0.0.2 bios he is using, memory stability took a dive with that.

    reverting to an older one could work on a 2000 series cpu, he still hasn't answered us whether he is using a 3000 series cpu.

    if its a 2000 series, Version 2304 or Version 2203 bios would be the trick.

    The review was done on 0505 btw, which was never published to their download center (reviewer bios?)

    2501 is rock solid for me, as was 2406 despite it's UEFI flaws.
    2008 was the first BIOS where is was able to go above 3466 MHz .. I think (not sure)
    But he should be able to hit at least 3200 MHz. If he's using a 2xxx chip then it's mostly
    about the SOC. I have no experience with the 3xxx chips since the 3900X still isn't available
    to buy here.

    1. 2700X
    2. The first and third slots from the CPU socket
    3. 1.1375

    So you are using A1 and B1 ... try to switch to A2 and B2.
    After switching to A2 B2 go into BIOS and change to 3200 MHz Stilt safe with SOC on auto.
    If that works then try Stilt fast 3200 MHZ 14-13-13...etc. still with SOC on auto.
    If that works then try Stilt 3466 Mhz and set SOC to 1.15v and if that works, then
    you can start to dial SOC down until you find lowest stable value.
    If you run SOC 1.15v in BIOS it will most likely come up as 1.1375v
    in Ryzen timing checker.

    Yeah ... still using 2501, since I'm still rocking a 2700X (3900X is on it's way - no idea when it will be here)
    But I have read conflicting reports regarding 2602. Some say it's utter crap others say it's due to old settings being applied and others say 2501 runs better.
    Personally I don't think it will make any difference to my 2700X, which is being pushed to the limit anyway.

    i believe the people talking crap about the bios's just don't understand the way PBO is intended to work nor have read AMD's reddit post about the core voltages being a result of applications polling too frequently.

    https://www.reddit.com/r/Amd/comments/cbls9g/the_final_word_on_idle_voltages_for_3rd_gen_ryzen/

    the lack of returning to low clockrates is intended behavior, a core in cc6 doesn't report its current speed, its just inactive.

    have a feeling the ones talking about Desktop/Mouse spiking their cpu are actually suffering the 1903 performance issue fixed in 18362.264+

    Use manual mem speed at 3200 and vram voltage at 1.35v manual again

    Switched to A2 B2, RAM is now stable @ 3200 with Stilt Fast!

    THANK YOU SO MUCH FOR ALL YOUR HELP!!!! :D

    2501 is by far the best BIOS for me compared to 2602.
    With 2501 it boost about 100 MHz higher with lower volt.
