Results of changing uF rating?

[javaman97]

I am having a very hard time finding any 3900uF low ESR caps, at least in quantities less than 1000, which I need 4.
What will be the result of recapping with some 4700uF ones I can get? Or recapping with some 3300uF ones I can get?
These are in the VRM section powering the AMD Socket A, running 1400Mhz. This is on Soyo K7ADA motherboard

I've done that same exact thing until I found some 3900uf. Works fine.

Sorry, of course using the 4700uf, not the 3300uf. Nichicon HE from Mouser also.

If you're in the US or Canada, I can get you some 4700uF Rubycons. I replace 3900uF caps with 4700uF caps all the time, never had an issue.

I'm confused,
I found 3 different lines in the digikey catalog that were 3900 6.3 12.5od low esr. Nichicon, United Chemicon, and panasonic.

Primarily, I prefer to use the E3 series (10, 22, 47), although I also prefer using the E6 series (10, 15, 22, 33, 47, 68) as well.
