Warnings & Disclaimers
Consider everything given below as “educational material” and provided AS IS to aid in the understanding of the true power in your shiny new KINGPIN-branded card. Proceed with caution and at your own risk as only you are responsible for the possible outcome of out of spec stress.
Overclocking/overvoltaging your EVGA RTX 3080 Ti KINGPIN graphics card disregarding type of the cooling, is quite an adventure and usually safe for the hardware, as long as it’s done correctly. Always pay attention to details and fully research these topics before doing any VGA alterations. This guide will help with some key information and specifics.
Having patience and doing things in small incremental steps is key. Testing after each and every modification will provide the best user experience while keeping your hardware safe and benching over and over again. Data provided in this guide was verified on multiple cards to best effort, but slight variations in numbers or results for graphics adapters are still possible due to different test conditions and running environment.
EVGA does allow the end-user to perform a standard replacement of the cooling solution on the graphics card without losing the product warranty, but that only applies if the device was not mechanically or electrically altered. RMA inspection along with circuitry on the card can reveal modifications, even reverted. Always be honest and responsible for your actions with this enthusiast product.

With Ampere its important to know that the clocks you see arent what you are getting. The best way I can describe it is there is Commanded clock and there is actual clock. Most of your tools and utilities will reflect commanded clock. There are 3 pieces of software at the time of writing this specific article that read actual clocks. Thermspy, Ampere OC Tool, 3DMark, and Nvidia Inspector are the ones that work. For simplicities sake id use thermspy or Ampere OC Tool as it reads both values. 3DMark only reads actual and NVIDIA Inspector software is sadly not publicly available.
ProbeIt monitoring header
For voltage monitoring purposes this card has traditional EVGA ProbeIt, which is a 10-pin 2mm pitch PH-type connector near the top PCB edge. Pin definition as below:
|Pin 1||GPU voltage / NVVDD|
|Pin 3||MEM voltage / FBVDD|
|Pin 5||PLL voltage / PEXV|
|Row 7||Onboard +1.8V power voltage|
|Row 9||Onboard +12V PCIe power voltage|
ProbeIt pinout is same since the GTX 680 era, so you still can use your ProbeIt setup if you had it done before. The only difference is replacement of +3.3V probe point with +1.8V rail instead. This I/O voltage is used as main logic level on RTX series graphic cards now, providing power for BIOS, display outputs and various onboard auxiliary logic.
Also same helpful labels with voltage names is located on the bottom side of PCB near each ProbeIt connector pin to aid connection.
VBIOS Switch available on card, to select one of three BIOS chips.
Just like all previous K|NGP|N Edition cards, 3090 KPE has three independent different BIOS ROMs and the corresponding switch to select between them. Default configuration with switch locked at right (towards power plugs), setting on NORMAL BIOS position.
BIOS difference comparison between the three is presented here.
|Normal BIOS switch||OC BIOS switch||LN2 BIOS switch|
|GPU Clocks Boost/Memory clock||1.92 GHz / 19.5 Gbps||Same as Normal||Same as Normal|
|Fan stop at idle/low load||Yes||Yes||Yes|
|Protection function||Full Protection||Full Protection||No temperature protection|
LN2 BIOS switch position disable temperature protection by hardware. This is a crucial feature to enable for LN2-type cooling, but totally unnecessary(and even dangerous) for watercooling/aircooling use.
Using LN2 BIOS position is not recommended for daily use, but available for benchmarking purposes.
If you want to enjoy maximum fan speeds that 90.02.30.00.79 version provide, you can flash it into “Normal” or “OC” position instead, to maintain thermal protection mechanisms and safety. Any of the three BIOSes can be flashed with unofficial KPE BIOS ROMs and operated independently.
BIOS can be flashed using NVFlash from TechPowerUp. You need version 5.567.0 or newer.
Card is already shipped with three different BIOSes, available for download as backup dumps:
Custom unofficial XOC BIOS
Current normal BIOS provided above (as shipped with card) with maxed out 144% power limit target already allow GPU to reach maximum everyday frequency without need of special VBIOS or risks involved flashing it.
However, if you want to do benchmarking with extreme cooling, you might want to get purpose built custom ROM from link below. Keep in mind, this BIOS is not for everyday use.
This archive is password protected to ensure you have read this guide carefully and agree with the risks involved of flashing custom binary into your KINGPIN. Password from the archive is ipromisenottoRMAthiscard.
XOC BIOS have next limitations to restrict its use only for benchmarking purposes:
- All fans are always 100% speed (“jet engine mode”).
- Fan speed curves or adjustment in PX1 is disabled.
- Temp target is removed.
- Power limit is not there anymore. :)
- Card ID is generic in this BIOS.
BIOSes in this section are compatible only with EVGA RTX 3090 KINGPIN card. These BIOS are unofficial and provided AS IS, without any warranty for education purpose only. Do NOT hotlink this BIOS on forums or social media.
Precision X1 Software
RTX 3090 KPE supported by Precision X1 since version 184.108.40.206.
KINGPIN RTX 3090 have special hardware to actually measure all the relevant voltages in real-time and report those measurements to Precision X1 which can read and display real measured voltages in software and on OLED. It works automatically with every 3090 KINGPIN graphics card and does not need any settings adjustment. Just make sure you use Precision X1 version 220.127.116.11 or newer.

There is traditional Classified tool available to play with various onboard KINGPIN RTX settings for maximum performance tweaking.
Uncheck “Auto” checkbox to unleash the beast. Keep an eye on temperatures!
Power consumption and stress to GPU is increased exponentially from elevated voltage, instead of linear for clock frequency OC only.
Do NOT set anything over 1200 mV for any type of near ambient cooling. Even with chilled watercooling and antifreeze your GPU temperatures under load will be positive and giving more juice to poor chip will only throttle it. It’s easy to see by lack of performance scaling (such as 3Dmark score / game fps).
When you use a tool, it’s a good idea not to mess with voltage control in Precision X1. Using multiple programs to control card settings can easily corrupt driver settings and create havoc. Great example of “Too many cooks in the kitchen”, because different applications do not communicate to each other, to gracefully apply settings.
This tool applies settings to hardware directly and settings will stay until the card is power cycled (complete shutdown). If you need reset to default settings – just power cycle the system, that will clear any classified settings. You do NOT need to keep tool open to maintain settings, they will stay set, until the card is power cycled.
For LN2 benchmarking make sure to disable NVVDD OCP and enable LN2 VRM mode settings!
There is also a modified Version of this tool. The only difference is you can send l2C commands.
Ampere OC Tool
Some more information about Thermspy is here
Local copies also available, just in case:
Water Block Options
There are no open loop water block options right now.
EVGA: Hydro Copper is planned but not set in stone if its going to be a separate item or if there is going to be a additional SKU with a preinstalled block. Regardless as of late December 2020 all Hydro Copper blocks were delayed due to QC issues in early production samples.
Optimus: Optimus PC has hinted that they are going to make Kingpin blocks but in their list of plans it is last and there is no ETA.
LN2 Extreme OC cooling compatibility
At this time there is only one LN2 pot available for ampere cards. That would be the one and only Kingpin Cooling Tek-9 Icon V5
Enjoy your overclocking!
