    Hello everyone! ;)

    I'd appreciate it if we all could take a moment and share our overclock settings in this thread!
    If you have any cool stories to share about overclocking feel free to do so. I love stories.
    Note: This thread is only for GT73VR's with i7-7820HK

    Thank you,
    Ralf

    My current overclock:

    4.4 GHz, VR Current Limit changed to 100A (value is 400 in the BIOS to get 100A) and Voltage Offset is -44mV

    More stable overclock would be 4.2 GHz, VR Current Limit is again 100A and voltage offset is -70mV

    100% fail safe overclock is 4.1 GHz, VR Current Limit is 100A, and Voltage offset is -80 to -100mV (test for stability if you do the -100mV but that'd result in much cooler temps)

    Max stable OC for me:
    4.7 ghz, VR Current Limit=200A, IA AC DC Loadline=5 (Intel IA Domain), voltage=1260mv (manual).

    Absolute max game overclock: 4.8 ghz, 1285mv manual voltage, same settings as above.

    fail safe overclock: 4.5 ghz, IA AC DC loadline=5, 1175mv manual, OR
    4.5 ghz, IA AC DC loadline=5, adaptive voltage, +100mv offset. (no offset is required if IA AC DC is set to auto (0), but temps will be much higher).

    please take a screenshot of where that IA AC Loadline is I'm still confused where to put it

    Right here:

    POWER AND PERFORMANCE --> CPU performance settings -> CPU VR SETTINGS -> Core I/A Domain.
    Change IA AC and IA DC from 0 (automatic= "180" reference value of 1.80 mOhms) to 5 to 10.

    DO NOT do ANYWHERE near the upper limits, ever, period. 180 is the reference value. 1 is absolutely NO VID Boost but a lot of vdroop so it hard to get stable. I find 5 works the best overall, but 10 might be good for you. @sirgeorge likes 10.

    You will have to REMOVE Your undervolt if using ADAPTIVE Voltage, or you will certainly be unstable because of too low voltage without the "VID BOOST". Depending on your CPU's default VID, you may need +50mv at 4.2 ghz to +100mv at 4.4 ghz.

    For static voltages (manual), just dial in the voltage. Seems like you need 1200mv on your system (guessing).

    ok so for a start, I set my CPU multipliers to 42X and Ring also to 42X although I know Ring will always operate at -300MHz from the actual CPU Frequency.

    I set the VR Current Limit as I always did before to 400 (100A) and IA/DC Loadline to 10 and a static voltage of 1230mV

    I got a 10C reduction in temps

    although I got random dips to 3.9 GHz a few times. What gives?

    Is it because speed step (IEST) is enabled? I know mine dipped like this unless I disabled that feature.

    I've always had Speed Step and Speed Shift enabled and I never had throttling

    Try setting VR Current Limit to 600 or 800 (150A or 200A). but this may just be a bug with moar MSI Spaghetti code dinner. I've seen random dips from 4.5 ghz to 3.5 ghz when fully idle, then suddenly it goes back to 4.5 ghz. Doesn't ever happen at LOAD. Only idle. Sounds like buggy C-states or something.

    Note: absolute MAXIMUM is 250A (1000). Found out. "Overclocking Performance Menu" shows a limit of 1000 for this value. But in the "OC" section, you can put higher than 1000. Going higher than 1000 literally flips this value back to default. Gross.

    Dude j00 are a star!!! you got my temps down by 10C with no throttling! Upping the VR Current limit from 400 to 800 fixed it!

    thanks a lot man! you are now the voltage inspector [​IMG] and overclocking doctor!
