Nvidia 1080TI component replacement

[karek]

I have an nvidia 1080TI that is missing a couple of the tiny components that are mounted around the main die. Any idea what these are and what their ratings are so i can find new ones and solder on? I am sure these need to be replaced as i have found one of them loose and floating around. This is an ASUS Geforce GTX 1080ti

Do you have experience with soldering tiny SMD? If not, try running it as is. If it works fine, just leave it as is. It will probably work just fine and certainly won't damage anything further. Soldering there without experience may cause more harm than good. As those are just decoupling capacitors, there are others connected to the same power rail in parallel.

Info about the card,
Before taking it apart I installed and tested it. The pc would boot up, I would enter password for win10 64, desktop loads and then 30 secs later pc reboots. Fan runs, card LED light up, 6+8 gpu power connectors light up blue. Figured I would check the thermal paste so I opened  it and the paste was all over the die and out over the capacitors, there is still small amounts of paste caked around the edges of the caps. Thanks for the info on the caps being in parallel sounds like they are overkill. Any thoughts on the pc rebooting after loading the desktop? The pc currently runs 2 gtx 670 in SLI and drivers are up to date, pc runs fine with the 670's but no luck with the 1080ti

Wasn't it conductive silver paste by chance? Missing capacitors could be the issue of course but I doubt that. The problem with them is that they are located very close to silicon die. So you can easily damage it, especially when soldering without microscope and fine soldering iron. Another problem is that substrate has high thermal mass, so it will be hard to solder without preheater underneath. What is history of this card, did you buy it broken?

Any thoughts on the pc rebooting

Does it crash with blue screen or what?

usually there you gor 0.1uF or 10nF caps, nothing more complicated, vcard must work without them
for beginner it's not easy to resolder them, but not impossible either
do a good visual check on tha pcb

Thank you for the information. I believe it is old thermal paste that is around each capacity, is it ok to leave it?
