Broken O2 Kingston DIMM - dexter1 - 01-18-2020

Today was a "soldering with your kid" day and we took out our stuff to do some hardcore soldering.
So i chose to diagnose one of the broken O2 128Mb Kingston DIMM's i got from the O2 auction last year. This is the front of the Module foridentification:



I've made a photo of the affected backside through my eye-loop to show the damage:



So c14 capacitor is completely sheared off, but i am in luck, the pads are still there.
I've cleaned off the remaining capacitor debris and have to find a replacement now.

Can anyone tell me what the exact capacitor value replacement is? I've tried to measure capacitance of the other ones on the bottom row of the board, they seem to be 20 microfarad. But i also know that the capacitance measured this way is affected by the surrounding components. If i measure the capacitance on the empty pads, my measurements are bogus and the value jumps around...

Ideally i take out one of the other capacitors and measure them, but they are so damn tiny i risk losing that capacitor .

I have the 128mb kit dimms with the same layout, sans the ic's on the one side. Same reading if that is of any assistance on mine...

I'm also highly interested in this!

I have some Octane RAM that is not recognized at all in any slot, and thought it might be bad or missing surface mount components. Because they're not being recognized at all I assumed that a cap over the power rails has shorted, if that makes any sense? My SIMMs are DATARAM brand.

Did you get any further?

This is supply pad (1st pad is vdd). Capacitor is for 99% supply decoupling connected between supply and ground. The accurate capacitance is not critical, you can try 100nF or 1uF.
