980ti shunt mod. Nvidia's GPUs will measure the voltage drop across a shunt with a known resistance, and through that metric calculate the current delivered by that particular voltage rail. Shunt resistors are basically a fuse, in effect. The 980ti roughly equals a 1070 and the 980 roughly equals the 1060, if I needed more than a 1070 I'd be out of luck. So what's the deal? So far I am seeing you shunt 5 resistors, the 4 by the PCI-E ports and 1 down on the bottom for the PCI-E slot. I left the memory and VRM controller sense resistors alone. My first try adding a shunt above 5 mOhms, 8 mOhms, did not trigger the cards safety Discussion So whats the deal with shunt mods? (self. Is there honestly much to gain by doing the shunt mod given the time, cost and potential risk? I'd only be looking for a sustained 2000Mhz boost. Work out what shunt values to use easily. It still eats away at the solder joints, even if . If it blew on its own, odds are there is a dead short somewhere that caused it to blow. Jan 13, 2021 · Yea, I watched all the videos, read all the posts. In this video i show the shunts and techniques i use to solder shunts on gpus for power mods A shunt mod will interfere with how power draw per VRM section is calculated. When using 5 mOhm resistors, as I did on my Titan X (Pascal), the 2080 Ti goes into emergency mode with a lot of loads (stuck at 300 MHz). The shunt layout is similar to a 3090, but not identical. I have been looking into possibly using a shunt mod to get more performance and had some questions. You put 5 milliohm resistors onto of the existing for Nov 13, 2022 · "Lots of people" is quite an overstatement, very few people shunt mod GPUs in general (it's almost never worth it outside of XOC situations since you need a cooling solution capable of 800W+), and most of the people who are willing to shunt mod the cards want to do it permanently (dedicate the card for benchmarking) so they do it the right way. We demonstrate how to short shunts on an nVidia graphics card, which allows us to increase overclock stability on our Titan V (or 1080 Ti/1070/etc). Feb 24, 2026 · I only modified the shunts tied to the 12-pin main connector and PCIe slot power sense rails. Very confused on if they have any purpose on anything that isn't a Max Q GPU. 4 days ago · A modder experimenting with shunt mods and cooling add-ons managed to push this Nvidia GeForce RTX 3080 Ti 20GB FE GPU to its limits. It seems no one is in agreence of how to actually do this. Contribute to bmgjet/ShutMod-Calculator development by creating an account on GitHub. I have the option of the shunt mod in order to bypass the power limit that I am hitting when running something like Firestrike Ultra where I boost between 1800-1900Mhz tops due to said power limits. The 12-pin FE connector is rated for 600W, with additional headroom available via the PCIe slot. Of course actual performance matters, unless you ONLY use the card to overclock Sep 30, 2020 · I have a RTX 3090 TUF. I would not recommend shunt modding without first verifying 100% that nothing downstream is shorted. It's a pretty straightforward process, just Aug 4, 2023 · After months of searching (occasionally browsing comments) I finally found the MSI enthusiasts Discord! These helpful psychos pointed me to the location of the GPU shunt resistors and got me going on getting this mod done that Ive wanted to do since January when I first got the laptop. 1) I understand how you can draw double the power, but isn't the 8 pin pcie power cable only rated up to 150 W? I understand that the graphics card would think it's drawing h Apr 11, 2025 · Disclaimer: I did this on an RTX 4070 Laptop GPU I know having a shunt mod on a 4070 doesn’t do much for performance but in the near future I will be upgrading my laptop to a 4080/90 where a shunt mod will be super effective and the principle is the same, so if anyone does have a 4080/4090 they can also follow the same steps. Pre-order Give your 3080 a 500watt power limit, step by step guideJoin the community over on facebook gaming, twitch and discord to talk tech and play some games with Oct 5, 2020 · I posted this in the RTX 3090 owners club thread and I'm posting this here for more visibility to anyone who might stumble across this: Edit: Added note about 6th shunt resistor & updated images Tonight I successfully shunt modded my RTX 3090 FE. For those Dec 1, 2018 · I finally got a chance to test some other shunts on my FE 2080 Ti. Aug 11, 2016 · Warning: This shunt mod is best used for doing bench sessions and the like, and not for permanent, long term installation. MSILaptops) submitted 1 year ago by Slore0 Water Cooled | GP66 11UH |i7 11800|RTX3080 Just put in an order for a 1440p screen for my GP66 11UH and decided to look more into the shunt mods. Please look up the mod for soldering a resistor on top of the existing resistors if you wish to do this for permanent, year+ use. zsw eft jkb pfx cvt aqw gxz zfs bbw jsb qvz yan vkp ltg rlf
