    LN2 OC TIP

    There is an FCLK cold bug under LN2 so try to stay around 1400~1600 for FCLK under LN2 to get a good compromise between temps and perf.

    To improve stability in this case:

    VDDG 1.15v, SOC 1.28v, disable DF Cstates.

    Depending on the CPU and FCLK, may have to control temps -120C ~ -170C.

    Do not be alarmed when it resets when temperature changes, pcie and fclk needs to retrain when temps change. Also sometimes there is temperature hole so going lower than it hangs may help.

    FCLK

    Biggest problem on the platform. 1200 default freq and supposed to go 1:1 with memory for best latency.
    Improves performance but limited, ~ 1800+ on air and 1400 on LN2.
    FCLK instability includes hang at postcodes such as ?07?, stuttering in OS, drop performance in Cinebench.

    CPU has FCLK cold bug.
    Improve FCLK Margin by using 1.15VDDG (too much will hang) and 1.3+v SOC. Since VDDG is sourced from SOC so SOC should be higher. VDDG only takes effect at 1400+ FCLK so under LN2 you need to set 1400. Higher usually fails during LN2.

    Enable LN2 mode, Use the Load LN2 profile as a base template, this uses low vcore so you can save exit when it?s not cold. You will need to do this before -40C to avoid cold bug. You need 1400 FCLK + 1.15v VDDG and 1.35~1.45VSOC.

    About AMD Limitations

    Safemode cannot restore back to stock memory settings as this takes place in the ?PSP? which the BIOS has no control over at that point of time. Either you have to clear cmos or wait for 5 times of post code ?F9? to get into AMD?s recovery mode. AMD?s recovery mode restores every AMD option back to stock, including timings and CLDO voltages.

    Because of the above, try not to clear cmos during LN2, at most go safe mode if your settings can be sustained with 1.5v DRAM, since BIOS will apply 1.5v for safemode when LN2 enable. IF you clear cmos, FCLK will go back to Auto and CLDO VDDG voltage will too. When cold, FCLK needs to be 1400+ and VDDG 1.15v if not Fabric will be unstable so you need to torch up to maybe -60c in this case. Therefore test your Memory settings on ambient first. Cold CPU improves Memory OC so you don?t need to worry about MC cold bug.

    TRY NOT TO CLEAR CMOS WHEN CPU IS COLD

    Very nice thinking of going for that board. Loving my Ryzen9 3900x best cpu have ever had so fast destroys anything in front of it.

    That's cool they got a new power and reset button now.

    I'm not very impressed with the clocks though so far.
    Not saying it won't do..
    They should beable to improve that eventually with a new hp process or something...

    Can these things reach 4.8-5ghz mem stable?
    Kinda funny the mem clocks are higher then the cpu clocks though :\., lol.

    From what I understand there's a small issue of boosting, chipset eat's up watts for some reason (I didn't double check der8auer's vid on the volt and amp diff's).
    And a randomization defect in the cpu or something.
    Another release that'll take a month or 2 to clear up, I feel sorry for the reviewers though.

    Theres a penalty for exceeding 3600 on memory dumo. And 1800 on nclock.

    After 3600 the 1/1 ratios is changed 1/2. Run a game or a 3d benchmark.

    You need to use uclock to get real gains over 3600.

    Sure it clocks to the moon but at a major performance penalty.

    Dunno about gaming or 3Ds chew* but heres 1:1 3600



    Probly ddr3 settings Cas9 @ 3600 needed to match 4600+Cas14 tights fclk 1900 memory benching performance.

    Too bad fclk cold bugged on ln2, kinda like FX 57

    results are what I expected. 3600 1/1 is on the heels of 4666 1/2. play with bclk @ 3600 lock the strap 1/1 and it will exceed that 4300 run. Also if you run a 3d bench it will stutter 1/2

    I'm kinda disappointed in these $600+ boards. From my x470 gaming 7 to my MSI God like x570 I have zero increase in core clocks. Memory clocks are a little better but x570 to me is am extremely hard sell if you already have x470. I expected more out of it. Just wish x570 could pull better core clocks or atleast the same with a little bit less voltage. But the second gen Ryzens are beast. The refresh was ok. But second gen dilivered and is what the FX should of been. These are worthy of the FX me unlike that train wreck they atemped a few years ago.

    On Asus this looks especially true. The c8f looks worse than the c8h.

    Is it all the extras they have on the boards? I'm kind of a kitchen sinker. I don't use all the options, but every few builds, I get the premium board.

    The extra are not good. Other than the aquantia lan the extras like the OLED and armor make it look worse. The liquid cooling for the VRM will make it run warmer, and there is no special sauce like the DIMM.2. The c8h is a premium board; the c8f looks like it is for suckers.
