    I have the the i7-3920xm in my M17x R4, was wondering what kind of overclocks folks are getting as in laptops the temps aren't the best. I know even with my higher CFM fan upgrade i can still see 50-60c at 15% usage aka idle in my case.

    Last year I had a play with a QBZU ES 3920xm in my P170EM - it is now in silicon heaven (instability then no boot, when inspected one pin was half black)

    XTU with Budget CL10 DDR3 1600mhz ram
    743 @ 4290mhz (heavy thermal throttle)
    776 @ 3890mhz
    This was on stock BIOS before I flashed Prema mod and with no cooling mod. Don't remember idle temps being bad but certainly the two pipe P170EM CPU heatsink struggled with any draw over 60W

    I was able to get 4.6 when I had mine. Others got anywhere up to 4.9. You should be good for 4.4 - 4.5 24/7 if you use a liquid metal paste.

    Depends on your sample.. M17x R4 has throttling problems so if your BIOS is fully unlocked etc, 4.5GHz should be doable.. I didn't have a fully unlocked BIOS so 4..3GHz was tops before power throttling!

    Does that metal liquid really make any difference?

    wouldn't 4.1 or 4.2 be quite bit more over stock? I have the UEFI and win 10 apparently i should i kept the bios? but, my fuzzy and hazy memory is telling me i'd have needed the UEFI for the gtx980. AFAIK, there is no unlocked UEFI yet?

    Yup. Get what you can out of 68W and call it a day

    4.6 to 4.9 must be wicked fast then!!! So if 4.2 is night and day 4.0 or 4.1 ought to be decent

    3920XM in my M18x does 4.2ghz all day no added voltage, I believe package tdp was around 63W under fulll load.

    And yes, liquid ultra is a must.
