Yes, I know it isn't recommended. Yes, I know it voids warranty. *spoiler alert* I've already voided mine with the Galax bios. 
 
Half a year ago, I read somewhere that the various bios for custom pcbs would not work on reference cards. Now I'm seeing people talking about installing XOC bios on their reference cards. I don't want to go down the XOC road, but I'd love to try that 520 watt bios. It still has protections on it, so I can't fumble and punch too much voltage into my card, or fry it with heat when I'm not paying attention. 
 
The reason I ask is because my watercooled EVGA XC Gaming on the 380 watt bios, runs all day @ 2,100, with a top temp of 54 degrees after the temp levels out in Furmark. It handles a 1,400 memory offset just fine. It actually handled 1,500 fine, but I didn't see any improvements in benchmark scores, so I dropped it back down. I've never manually overclocked the chip or the voltage, I just let OC scanner pick what's best, and it reported that my power limit was the defining factor in my OC. That bargain 2080 ti managed a respectable 10,351 in Port Royal, and now I want to see if it can do better. :D

I’m not sure if u can benefit with the kingpin bios, I have kingpin 2080 ti with basically the same temps as you and the most my card does is 2130 some times 3dmark says it’s 2165 but gaming it locks solid at 2115 and maybe when my basement is cold and pc is cooler I stay at 2130 gaming, I don’t know if 30 to 50
MHz is worth voiding warranty for little to no benefit,

Grrrrr... 

The Kingpin 2080Ti has a Totally different Power design. 

So if you try make sure you get it Recorded & you can watch the magic smoke escape over & over - if it even boots

So are these guys claiming to have the XOC variant on their reference cards, outright lying?

Re: Flashing FTW3 with Kingpin BIOS - possible? Is there any OC benefit?

FTW3 card will not work with KPE BIOS because different VRM design.

 
 

 
I have no idea how a stock "reference" 2080Ti would even approach the use of 520W BIOS & @ what kind of temps

Power target and power limits

(excerpt) --> You need to read the complete guide, this was interesting section
 
However, KPE RTX 2080 Ti designed in a way that does not require any additional power limit modifications or thermal protection removal mods. You don’t need to solder anything on the card to enjoy LN₂ benchmarking with KPE. That is what this card is all about. It can overcome the power limit or any thermal limit with a proper BIOS. It is 100% designed to run at full LN₂ speed without even touching the soldering iron.
Cards overclocked with LN₂ and running 2500+ MHz, can take some serious power. Ensure that the PSU is at least 1500W and adequate for the job. Typical middle range 1200-1600W 80Plus Gold rated PSU should do the job well. For extreme overclocking we highly recommend running the system (CPU, peripherals, fans, motherboard) from one PSU and the VGA card from a separate second PSU with at least 90 A of current available on +12V rail.
 

I suspect if the Kingpin can handle the 520 watt bios with it's block, and 280mm AIO, my 560mm rad with 8 fans can handle the heat.

I'm not sure if these guys are full of pooh or not, and if they are being honest, how they managed to get it to work.

I was reading his guide earlier today.

I know my little XC wouldn't utilize the whole 520 watts, but I suspect it could use more than 380. ;)

Hey, it made 78th place in the Port Royal HOF for single GPU, you can't blame me for wanting to try for a better rank..

The PCB may be the actual Achillie's heel .... I'm guessing --> as it is above my pay grade.  Those 3x 8-pin power sockets on th KP are there for a reason
 
Yep 360-380 W --> OK, not burning it down - its the 144% that make make it smoke - outside of LN2 cooling
 
The Volts required would make sub-zero & hard mods required ... hack Boost 4.0
 
Congrats on your score 
 
Time to move it into a super cooled bench area .... & crank the AC to Frosty ... see what it will do

Thanks.

Remember that the non LN2 bios has heat protection, and won't go over the standard Nvidia voltage limit, it just bumps the power limit to 520 watts, and cranks up the fans. That is why I'm interested in that one, it'd protect me from doing something stupid.... KP himself stated that his 280mm aoi is good enough for that one.

If you can't keep the card in the 30c range, I wouldn't worry about trying to increase the power limit.
 
Mid 50c is high for a water cooled card even on a power virus like Furmark. 

time for Chilled water ... keep an eye on the dew point
 
those chilled loops will "make it rain" on your PC

@the_Scarlet_one
 
Which case did you manage to fit 2x 480 and a 360 in?
 
@OP I heard the Galax bios is better on the reference than the KPE XOC anyway. Suggest not flashing KPE XOC on ref...
