Okay, I went and did it tonight. First a short explanation.. My secondary computer I use here (that's what I call it) is primarily for chatting, web-browsing, youtube, discord, telegram, etc. My other big computer with the 1080 Ti is almost exclusively dedicated for hardcore gaming. That said, some days I feel sick/exhausted/miserable IRL and may not feel like gaming or if I do I may feel like "Light" gaming and not anything "Big" that would require booting the other big gaming machine. So Some days I may just sit and game on this secondary computer in something simple to pass the time. So I don't really need super big gpu power in secondary computer.. so 1060 3GB in it. My big gaming computer has the 1080 Ti in it.
That said.. if I have any computer, I do want to get the best out of it so secondary computer runs with a i5-2500K @ 4583 Mhz and I tried to shunt mod the 1060 tonight in it and I had great success. The mod went smoothly, and it worked as expected, and I was able to overclock a little more. Which is to say not a lot in the end.. it is a 1060. But it was more of an experience than anything. I paid $55 for this 1060 earlier this year so I'm not -TOO- concerned if I bricked it.
Anyway details. I know the "main" way people have been doing shunt mods is by painting on some sort of conductive thing over the contacts of the shunts and then lacquering over it with nail polish. Well I wanted to go a more permament method and so I got my soldering iron out, heated it up to almost the maximum heat setting and I just flowed a bit of solder across the top of the shunts. Worked fine. Pictures to follow.
Not the prettiest job but this won't be seen by anyone so I don't really care. It's about function anyway. Before at stock configuration: I could set core to +180% which resulted in 2114 Mhz core speed but I couldn't increase ram speed at all. Even +25 Mhz on ram speed would result in 3dmark crash in firestrike instantly. And power % would peak out at the +14% limit at 114% - 115% almost constantly in more demanding games. Now with the shunt mod I first ran 3dmark with it at +180% core speed and it was reporting only 83% power instead of 114%. So the shunt mod was working. And then I was able to slowly work on dialing in the ram and my final result was +875 on the ram and +175 on the core.
Here's 3dmark results:

It's a small gain, but a gain is a gain. I'm considering looking at a faster card for this secondary computer this fall. Maybe try to find a Zotac AMP! Extreme GTX 1070 with the 8+8 power connectors. Or some sort of similar GTX 1080 if I can find one with 8+6 or 8+8. And then which ever one I do get, shunt mod it. I had used some ebay bucks to buy this 1060-3GB a few months ago earlier this year so I actually only paid $51 for it shipped out of pocket so this was my experimentation card. Turned out it went fine and now I'll probably shunt mod all of my no-active-warranty nvidia cards from pascal and up from now on.
Do shunt mods work for older cards too? Like the GTX 600 boost series? GTX 700 series? GTX 900 series?
