Works for 1060 and above. There should be three shunts but you only need to do the two closest to the 6/8 pins.

There's some claims that LM eats away the solder NVIDIA uses so I took mine off my card after I was done testing

Here's a video where he (incorrectly) blames NVIDIA for doing a crap solder job but in reality the guy requesting the repair did the shunt mod and removed it before trying to get the card fixed.


It's really only an issue if you get liquid metal on the solder for the shunt versus just getting it on top of the shunt. Making a hot glue "barrier" and then putting LM is what a lot of people are doing.

This is a great thread. Glad someone was able to find the right case code size of resistors we need to use. Ill try to add links to the resistors and recommend that route in the liquid metal thread from a couple years back.

Hi,
Took a long time before I could actually see you post yesterday thank again
For some odd reason I just couldn't access in anyway :confused;

But yeah I was leaning away from the LM method because of the very reasons you pointed too
Kind of surprised people don't cover the 5MO black part with a small piece of wax paper or something to keep LM off of it and just branch the two ends together those are the parts that need the connection correct.

Right when these cards came out and people started doing this 'shunt' mod I decided for myself it wasn't worth the risk of killing my 2 1300€ cards. Since then I didn't look back at this until now so can anyone remind me again how much fps gain this mod gives exactly ? Is it worth it after all to do this to my existing cards ?

Hi,
Not sure this is about fps
It's more about tricking nvidia driver power throttling which limits core clocks which can produce more fps I suppose but it will "hopefully" ultimately improve benchmark scores.

It is the difference between keeping a consistent clock speed, and dropping 200~ MHz in various parts of games and benchmarks. It is a very worthwhile mod, IF you cant do an easy bios mod for increasing power limit.

Hi,
On an nvidia card bios and driver is an issue
On third party it's mostly the driver flagging the throttling but by nvidia rules a manufacture can't alter the bios past nvidia's power limits.

King|pin came up with one for the ftw3's slave bios though
But it does nothing for the nvidia driver problem but it does give a little more grunt and fixes the slave bios to a point

any benchmark of the % of difference before and after this mod I'm thinking of doing it but if it only yields 1% gain I wont

Hello, one question because mi resistors fell off from lm after two years 🙂 when i was cleaning the card. Should i solder 10 Mohm resistors directly?? Could you give me a link to valid pair of then thanks!!!!

Aren't the standard resistors on most recent NV cards 5M0? Why would you put on 10Mohm to reduce the power limit? Usually some older cards worked with 2.5Mohm but newer only 3Mohm. 1/(1/5+1/5) = 2.5

I haven't mod it myself yet but I got the resistors from Aliexpress, you can either find individual values or get a pack of several. Package size is I think 2512.

Using liquid metal that reacts with most other metals is stupid. Galinstan is difficult to use as it reacts with just about anything.
