I'm going to buy the 138C solder paste to make it easier as well as the 8MO shunts.

Is there any way to confirm it is seated properly, to avoid disassembling the GPU again afterwards? I'll be doing this mod on air at first and maybe water later.
As renegade said,
I just did visual inspection of mine, also I noticed the ek block and backplate are very close after putting shunt on- worth putting some electrical tape on top of shunt to avoid shorting against block.

UPDATE ON THIS BIOS: It SEVERELY cuts the NVlink bandwidth. Opinion is it makes multi card setups pointless as the link is crippled. Still great for single GPU setups though, if your card works with it.

I will be sticking with the stock, upgraded (from evga) BIOS for these cards as none of the others lets me get even close to the memory speeds I get with OEM. I also will be applying the shunt mod to raise my available power limit. Lastly, waterblocks will be installed (already have them, just no time with 4, soon to be 5, kids).

I used clear nail polish my wife had lying about as I couldn't find my can of liquid electrical tape. This is a good idea though.

Do you guys recommend using the stock Strix 2080 Ti vBIOS with the Shunt Mod or a different vBIOS?

Thx for the help!

I'm getting my heatkiller this week and since I'll disassembling my current block, I'll also perform the shunt mod, I bought the 8ohms which OP @Asmodian posted and solder them on top of the existing ones.

just to clarify; I'll do that on the bottom right shunt and on the top right on the back, right? Not on the once near the PCI-E connectors?

Just take a multimeter or look at the PCB it should be quite clear what shunt is for what connector.

On Turing it seems NV has lowered the "limit" and only 3mOhm works, not 2.5mOhm anymore. 5+8=3.08 or you can buy a 3 if you want to desolder the original 5.

Stock or XOC on water. The Strix card is what XOC was made for AFAIK.

I recommend using the stock vBIOS with this mod, you do not need to allow more power after it and that way you get all the timing information Asus designed the card for (not that this is likely to be important based on user reports).

FE card
If it is an FE card then you can look at my photos in the OP, I have highlighted the two resistors to add with red squares. You are correct, do not add one to the lower shunt on the front.

thanks. I ****ed up and put the shunt on the bottom of the front, not to the one who is nearer to the PCI-E connecors. what are the implications of that? It's not going into safe mode for me?

Won't boost as high and might damage the pcie slot on the motherboard.
