Usually very small caps have a tiny 3 digit # on them that denotes μF If I had to guess this is a cap that regulates voltage swing. If you have a high quality power supply this would be a cumulative cap to cut high values. powerequalsisquaredr |

I think it is a bit of a mystery and I like the overclock scenerio here most. Remember these components have a 20% over tolerance so the other inline caps will make up the differential by this lost unit. I would get a thermal gun and check the inline components after processing heavy graphics or a zero point calc. powerequalsisquaredr |

Unless you have the knowledge and equipment to de-solder a solder in a new cap. And I don' t think you do... Is it an electrolytic capacitor? Those havea gel layer inside, are "polarized" and can only go in one way(or else they'll "burst" their packaging). "ceramics" are fine either direction. |

They can provide timing, voltage pull-up source for a line, power filtering etc. A cheap soldering iron is $10 plus $ for solder. Quoting: Anonymous Coward 79629378 Getting a new ryzen 5000 system end of the month so it just needs to last till then. The board is 8 years old so its probably going to be scrap anyways.With my luck, Id probably short the whole board out trying to solder it back in. Appreciate the replies guys, thanks.

No overclock, maybe widen your memory swap files also in the mean time. I like your chances for 30 days. KNOCK WOOD! powerequalsisquaredr |
