Also, I assume I will be needing 2x 8 milli-Ohm resistors for this so if there are certain ones that are better than others for this I'll go for them to make sure this works properly. Do I use 60/40 or leadfree or some other option for soldering it?
Oh, and could you just as a reference show exactly where those resistors are on the PCB?
Just out of curiosity, will the raised power limit reduce the lifetime of the card in any way?
I used a very cheap soldering iron with a small flat tip and the mystery solder it came with. It needs to get hot enough to melt the solder under the top resistor, which is pretty hot. It has a knob to adjust temps but no reference to know what it is set to, I had to turn it up almost all the way. I should have taken it to work, I probably would have done a much cleaner soldering job.
These are actually pretty big surface mount resistors so it isn't too small of a job. I did link the resistors I used in the original post, they match the shunts used on the card originally too (except being the 8 mOhm version).
Edit: oops, no I didn't.
I did a few posts down but they are Panasonic ERJ-M1WSF8M0U
current sense resistors.
More details on how I did the soldering in my Titan X (Pascal) Shunt Mod
The power limit will only reduce the life of the card if you also over-volt it and/or run it really hot. I edit the voltage curve to keep it at or below 1025mV and water cool it so I don't expect unlimited power to lower the life. However, we don't have any historical data, of course.
I have highlighted the resistors:
