    @Papusan, can I ask how you get such high Cinebench scores with this CPU (740+)?

    I barely get more than 720, and I'm not able to replicate it like I did when I first tried.

    Also is it just getting lucky with the CPU, or how do people do -100-200mV on this CPU? I don't get more than maybe 80-90 while also being stable.

    I'm new to the site, wasn't sure how to contact you...so yeah

    Hi. And welcome to NBR:)

    You'll need to use ThrottleStop to set Amp + power limits, and same time be sure the cooling can keep the Cpu below the temp throttle point (100C). Some OEMs put temp throttle limits below Intels specs due use of cheap components/cooling and the clock speed will start drop way before it has to (the bench scores will drop together with the clock speed). Be sure the cooling can handle +30W.
    80-90mv undervolt is quite common (how far you can come depends on the silicon lottery). Some can probably do a lot more but this is more rarely. 200mv undervolt ist the standard.

    What did you have your amp + power limits at? My cooling seems to be fine, I can sustain ~34W without crossing 87 degrees in the worst case. I also do get 3.4Ghz on all cores (well, 3392Mhz), so not sure at all what is limiting me here, even to get to 720cb or so like I used to(I barely get 700cb rn). My C State isn't locked to 100%, and fluctuates from like 99.8% to 100% if that matters.

    ThrottleStop will tell you what is limiting performance - click the Limits button and see what flashes while you are running a benchmark.
