Gamers nexus RTX 3080 overclocking live stream question

I was watching his RTX 3080 overclocking live stream last night and with the evga RTX 3080 FTW 3 ultra he said he had a way to increase power limit but he couldn't share it on stream because evga called. Do you guys have any ideas what it is and how to do it? I assume its a custom vbios because a shunt mod would take a lot more time since it was on a stream but I can't find any traces of custom vbios for the card online

Probably a shunt mod or some first party developer tool that he isn't allowed to talk about. Slapping another 5ohm resistor on one of the 8pin rails would already get him like.. 75W. Der8auer made a video on the shunt mod a few days ago, check it out.

Either a custom XOC BIOS or a shunt mod.

 

Honestly, shut mod is not that difficult to do and its way better than a custom BIOS for overclocking but obviously, depending on how you do the mod, it may or not may ruin your warranty.

Shunt mod for sure. Violates the warranty and if done improperly will lock the card in a lower power state and can adversely affect the power states/GPU Boost.

 

Way too early for custom BIOS.

I found that video odd. GPU-Z was still reporting the PerfCap reason as power, even after the mod.

You have to look at power consumption (TDP). It dr791475473_Screenshot2020-09-18215504.thumb.png.4cdc3de67723430380a1df38f5ff9694.pngops from 100% down to 80%. That is the difference.

Ampere probably has new detections. Shunt mod can do weird things on Turing and Pascal. Maxwell was a bit finicky with it.

 

Kepler was the platform where it really worked. Big blob of solder instead and the reported power decreased 10x.

Yeah I noticed that, and the reduction in the reported wattage from the 8-pin connectors. Which is why I found it odd that the PerfCap reason was still power despite the 80% TDP number.

The default cap is power, even if you have reserve. And then temperature. The only time there's no "cap" is when the card is idling. I believe that's how it is. Most certainly the way I've observed it with my system.

That is not my experience. I'm sure it depend on the card. My RTX 2080's power limit is well beyond where I could ever go, so my limit is usually related to voltage when it isn't idle.

Quite possibly.. I run an older pascal 1070.. and my rtx 2060 laptop is usually power limited, even if I'm not using the whole GPU power.. idk

Anyway, I certainly look forward to more power limit/power limit moding related information on these cards.
