    Nope, wont let me change the rate, no options, just the res.

    Yeah I'd think this was a no-brainer. Err...apparently it is 'cause I can't figure it out.
    AC is plugged in of course. Maybe this TV doesn't have the specs it claims to.
    It's a Visio M321i-A2.

    Not to be a bummer but I doubt that. The NVME NAND drives are all so close together that any performance uplift from the minuscule increases in low QD performance should be largely unnoticeable, additionally, at this level of storage latency, the CPU actually plays a bigger role than the storage medium. As an example, I migrated my desktop install from a 512gb 960 Pro over to my new 480gb 900P (an over 4 times improvement to low QD performance) and there was little raw responsiveness difference (which is surprising considering the 4x improvement in speed), the main perk was better consistency rather than anything else.

    The thing that really made the difference to responsiveness was overclocking the 7700K to 5.1ghz and tightening the RAM to 3466 14-14-14 1T. However, the responsiveness gain was equally noticeable on the 900P and the 960 Pro (although the 900P can sustain this responsiveness in all scenarios whereas the 960 Pro would sometimes randomly slow down).

    My point is, if migrating to a 900P showed so little difference, I don't think you can see the difference between NVME NAND drives.

    Also technically speaking, the 3D TLC nand drives should be more responsive than the MLC NAND drives like the 970 Pro because the 970 Pro does not use an SLC cache. SLC will still always win vs MLC.

    When I get the time, I'm going to benchmark the 800P on this laptop but I'm not expecting miracles.


    Likely to be changes to ambient temperature or operating temperature. Pascal is extremely sensitive to temperature so even changes of around 5-10C make the difference of 13-26mhz at any given voltage bin.

    I see it frequently with my desktop 1080ti. In winter where my loop can keep the GPU <40C, I can push 2100,mhz/2113mhz but in summer, where the GPU is >40C, I need to drop the clock to 2088mhz (sometimes 2075 on hot days).

    The new BIOS 1.5.0 did something to CPU power consumption. I was never able to undervolt past -125mv and -130 it would occasionally crash. After this new BIOS update, I can undervolt to -145mv and it’s stable. Hasn’t crashed once.

    For me, it seems like Dell's in-hired softeware engineers play Russian roulette with AC / DC Loadline settings in firmware. What's next? Play with fan settings? @Falkentyne :rolleyes:

    Will try, sounds awesome. Are you using speedshift or speedstep?

    I am not sure what they did but -.145 I could never undervolt that low.

    How did you get the Intel iGPU driver to install without getting the black screen of doom?

    If you use HWInfo64, after a bit of idle time, can you (please) see minimum voltage reported?

    I am at about 0.520V on speedshift, could go as low as 0.512 on speedstep. My underclock is -1.299 as per TS on both CPU and cache.

    I wonder if this (Bios 1.5.0) has any connection with my GPU crashing @0.800V 1721 MHz +350 memory. Now I have to use @0.812 1708 MHz +350 to be stable.

    Could also be the extra 2-3 C heat though, my room is a sauna @Marksman30k.

    I uninstalled (now legacy) intel driver through programs and features in Control panel, restarted, and installed the newest DCH driver. No DDU.

    Damn, I forgot to test @Vasudev your suggestion.

    I am using XTU to undervolt
