Weird Problem With Capacitors

[bulkchart32]

i'm not well versed on how to interpret the readings on capacitors but my understanding is that the uf should go down as the cap is wearing out. i pulled a couple of 3300uf caps off of a board and they are both reading over 8000uf in my esr meter. i tried some new caps to be certain that the meter is reading correctly and it is. why would the uf go up on an old cap?

That is a bit odd

The cap's that are fitted  in the  Xbox would have a +/- 20% tolerance 

I would replace it anyway and I normally don't bother testing the old ones I just chuck them straight in the bin.

Was the test done with the cap out of the board and did you discharge it 1st?

Also Dr Google came back with a couple of the same questions but no answers.

Soft modding is like masturbating, It gets the job done but it's nothing like the real thing.

they were all 3 out of the board. they were the 3 right by the cpu/gpu. 2 of them were over 8000 and one was almost 8000. i did replace them. i found that very odd, though.

The Caps where probably going open circuit I have had some out of amplifiers that look 100% but the ESR meter would not read anything .
