I have found this mb, which is good except that most of the capactitators are bulging and during the boot most of the times the ram doesn't get detected (like 1 stick of 2 or 1 of 4!), once the system boots everything works fine (apparently), I saw there are 10 of them on the mb, I'm going to change them all just to be sure.
They are: V6.3 3300

Which capacitators should I buy to change them? Where can I buy them? I live in Europe, Italy to be precise.

Thank you in advance.

Use polymer capacitors 6.3V, 1500uF, with ESR of approx 0.012 ohm at 100khz.

Thank you, any advice where to order them?
I found this website:
https://it.farnell.com/kemet/a755ms158m0jaae0 … v-20/dp/2614040
https://it.farnell.com/wurth-elektronik/87013 … v-20/dp/2466572
Those are like the one are installed now: https://it.farnell.com/rubycon/6-3zlj3300m10x … v-20/dp/2346439

Which one are better in your opinion?

These are close to perfect. I recommend these. Same ESR as original capacitors, and I've used polymer caps of these specs before with good results.

These will probably work as well, but ESR is a bit low, so more likely to cause problems.

These have twice the ESR of the original caps. These might work, but will probably overwork the replacement caps and eventually break them.

Thank you.

Shipping from Farnell to EU is around 5 euros by next Day air mail. Can't beat that.
