I know this thread is sort of old, but I will show you my specs and for future inquiring folk who want to overclock a 3940xm:

Just read your post and was hoping you might inform me as to which unlocked bios you are using on the M18xr2 ?

I have the same mods as you using 3080. On overclocking I can only set the flex ratio override to a max of 25 and yours is set to 32 ?

I know that the 3940xm and 3920xm have differing available settings are you using 3920 on the m18xr2 in the pics ? I am using Swick unlocked A11

Thanks

I have A11 Unlocked also but the mod is sv17. Not sure if thats the same guy or two different modders as im not informed too much on that sorta stuff. I just downloaded that one since it was the first one I seen.

When I have it enabled it just defaults as 32. Last time i changed it (I forget if I was setting it higher or lower than 32) it blue screened before windows even started and wouldn't turn on so i had to resent CMOS and im not going through that again lol.

What mods do you have? All same as me? Even the optional ones? Also which CPU do you have?

M18xr2 with unlocked a11 by swick/ Svl7 with 3940xm 32gb of 1866(needs to be 2133mhz but impossible to find anymore) Using and xvision rtx3080mxm that the vbios is locked to 115w. Trying to get a great firestrike score with oc from the bios. Seems I will have to use Intel XTU for tuning my oc. Did you download the a11 from ssj92 on this site or another?

Thanks

I have 2133 in my other m18xr2 but I don't really want to break down that set up right now

Looking for custom heatsink for M17x r4 for the 3080 with backlight mod as a next project.
