    I'm having this specific card here: https://www.gainward.com/main/vgapro.php?id=1154&lang=en
    I already posted in the 3080 thread but wanted to create my own here, it's easier for me to navigate and stuff like that.

    So yeah, i was simply wondering if i should undervolt or oc my specific card, since i'm new when it comes to things like undervolting, i was wondering if it can actually help increasing performance or is it always less than an actual OC and only provides lower usage and temps?

    If i should undervolt, where exactly should i start?(from a guide, i tested 1900mhz@950mv), but i'm not sure if that's even a decent enough value for my specific card.

    What about a proper OC with the OC-Curve auto editor for example, is that a good idea with 3080's?
    If so, what values are a good starting point when it comes to Core Voltage, Memory Clock, if i even need to touch them.

    I just want to get the most out of my card and would really appreciate if you guys could help me out and explain it to me, so i actually understand what's going on.

    As always, thank you guys :)

    Undervolting will basically turn your card into an efficient gaming beast, as opposed to power hungry beast.
    At max you lose 50mhz on your clock, usually tho it's around 20 if even that least im my experience.
    It's very easy to do using afterburner but as all cards are different you'll have to experiment, something i love to do but others not so much?
    Start tweaking your card without using UV first to get to know it.

    I posted a picture in the 3080 thread if you want to look at it, just wondering if the things i've done to it look okay.

    Or i can just post all my settings down here:
    Core Voltage at 0%
    Power/Temp limit both maxed out
    Memory Clock is at +500mhz
    In Curve Monitor, the first thing i did was to put -290 in the coreclock, then adjusted it to 1905mhz @950mv(i don't know if you have to put it down first to minus 290 or 300, or if that doesn't even matter).
    I just want to learn how to do it properly :)

    Go to curve editor, find a decent voltage then raise the voltage dot on the graph to your required clock speed then press 'L' then enter, then exit and apply in the afterburner ui.
    leave memory till last imo.

    Yes, and the idea is to have the lowest stable voltage you can, i undervolted my 2080ti to the utter max, pretty sure i had the power limit maxed.
    Try using a lower voltage dot and slide it up, and monitor your gpu power usage, i shaved over 100w when i done it.
    Lowering power usage is the main goal, which'll bring your temps right down.

    and what about actualy performance gain/loss? is it noticeable?

    Your card will run the best it can undervolted as it does regular, that's why it's magic.
    If power usage doesn't bother you then surely much lower temps will.
    It's a new card keep it cool, don't undervolt too much and starve it, and take your time.

    I'll leave it at 1900mhz@950mv for the moment until more people get their hands on the same model, I'm pretty sure i could go even lower to like 900, but i think this should do it for now. :)

    Thanks for all the information, really appreciate it.

    First find stable core overclocks then follow this undervolt guide
