Anyone know what values the caps are on the bottom of the Epyc cpu packages? I bought a few duds off ebay with the hopes of repairing them. My meter however is not sensitive enough to read a value on the cap array which makes me think it must be in the PicoFarad range.

I was able to get a reading on a different one. 2.75uf. that's huge for such a tiny cap! it's .8mm by 1.6mm which would make it 0306 package. I don't know that i've ever seen anything that small with a capcitance over .47uf

did some more probing. it appears to be a single interdigitated capacitor instead of an array of 4. that helps explain the high capacitance.
