Der8auer volt mods a 2080 and does a lot of overclocking. Even with significant subzero temps, Der8auer shows that voltage barely helps the card at all. One of my questions was, “why can’t we control voltage up to 1.2 volt at least???” Der8auer shows that even dry ice and 1.2v, power consumption doubles and barely any speed is attained, so yeah... that’s why we can not have voltage control up to 1.2v lol.

    Interesting. Thanks!

    Around the 8:20 mark, he states "the power mod drastically increases power consumption, (from around 15-17A to 20+A) and you only get 20-30 MHz more) it's really not worth it."
     
    Glad we know that now!

    It looks like a water block gets you a quiet card and a few Mhz, but for the most part it's a buy it and run it kind of card.

    I am skeptical of his measurements.  Those numbers just don't make sense.  Why would the power consumption increase so much but performance not increase much.  Where is the increased "load"?  The core voltage increased 0.01 volts and the core frequency increased 30-40 MHz.  Does that account for 34.6% increased power consumption?  It doesn't seem to add up.
     
    Ah ha!  As he says earlier in the video "Power consumption only measured from 6 + 8 pin connector".  Since the card has power shifting, and since he isn't measuring the PCI-E slot's power consumption, I wouldn't doubt if the power consumption of the PCI-E slot dropped significantly after it falsely sensed so little 8-pin PCI-E connector power consumption, and that is one reason why it appears that 8-pin power consumption has increased so much.  The graph shows a 34.6% power consumption increase after the solder mod, but what if the PCI-E slot power consumption had at the same time dropped 30% and therefore the total power consumption increase is actually only 4.6% instead of 34.6%?  I think he should do some additional proper measurements.  If the card suddenly detected that the 8-pin PCI-E power connector was drawing only 10% load, it would make sense for the card to shift 70% PCI-E slot load over to the 8-pin PCI-E power connector and therefore the 8-pin PCI-E power connector load appeared to shoot up by a drastic amount.
     
    Since he isn't properly measuring the card's full power consumption from all of its available power sources, all power measurements he makes are kind of worthless.  They aren't even valuable for the purpose of comparison since the load shifting will play against him in the background in an unpredictable and undetectable way (given his measurement methodology).

    Great analysis, however let's say his power consumption numbers were off...(and I understand for benchers this may be significant but not for everyone), an increase of 30-40 MHz isn't significant enough for ME personally to hardmod.  Whatcha think?

    I am pretty sure that I agree.  But, at the same time, I voided my video card's warranty with a hard mod which, in the end, only netted me a 0.4% performance increase.  So, it really depends on the individual.

    Now I wonder how the Kingpin brand will enter the arena, if there is such thing and tbh, there's no point for one at this point by the looks of it.

    Generation after generation, there seems to be less and less of a reason to make/buy a Kingpin edition card.  I thought that the 10 series Kingpin card was quite pointless...
     
    The Kingpin cards are turning more and more into a card that people will buy just because of the name and just because they are too scared to modify a reference card.  I guess some people will pay 75% more just to be an average of 0.5% higher in some overclocking leaderboard.

    And when I point this out to people I'm met with vehement derision. Maybe because I also call these people idiots. Truth hurts, huh?

    Sajin showed that on air, with lower clocks, the kingpin did produce more FPS and higher bench scores. And it costed $400 more for a couple of points and FPS.

    For real Extreme Overclockers, it really is a great buy... but for Air/Water users, it’s just a bigger boost to their everyday ego for gaming as it definitely doesn’t make any games better.

    Yeah, it's so not worth it to have your gpu running at a solid 2100 MHz all the time. 
     
    Just that alone is gold as you'll be able to test your cards true stability with furmark without the core dropping down to something stupid low because of gpu boost.

    Buildzoid did a video about the MSI 2080ti Gaming X Trio and actually mentioned exactly that same thing that you said. He said it would cause a big imbalance in the testing because of the power balance feature.

    Good catch :-)

    Sharing the Gaming X Trio breakdown video in a moment.. it’s a mind boggling 30 minute video where he shows that MSI legitimately made a reference PCB with one extra phase, and a relatively useless 6 pin.
