ATI R9600L cap ID

[socketa]

Got an AGP card that just started ghosting on the boot screens.
On the card is 8 100uf 16v 5mmX10mm aluminium electrolytic caps.
They appear to be Ark caps (after looking up the symbol A that is printed on the caps)
One of them is definitely bulging on the top, and another has a dent in the top.
There is no marking for series except for perhaps (M)
What would be a suitable replacement for these?

All the searches on this site for ark (except for one) are for noah's ark, and misspellings for arc.

Here is their site:

But I wouldn't worry about the series. Just replace all the caps on the card.

For the three big green G-Luxon 6.3V 1200uF caps, use Nichicon HM/HN/HZ class capacitors. I can't identify the value on the 8mm black cap, but that should also be Ultra-Low ESR.

For the 5x10 caps, use Nichicon PW class or better.

Thankyou,
Will use Rubycon ZLH for the 5X10 caps, and update thread with result when done.

Re: ATI R9600L cap ID

The 8mm black cap is a General purpose G-Luxon SM 470uf 16v, rated at 315mA ripple.
What would be the best replacement? :
Nichicon HN rated at 1800mA
Rubycon ZLJ rated at 1200mA
ZLH rated at 945mA
or
should i look for something nearer to 315mA, and if so, why?

Re: ATI R9600L cap ID

ZLH should be enough. The others might be too low ESR and disrupt the functionality of the circuit in some way, although that's not very likely.

The higher the ripple current, the better. It's ESR that needs to be somewhat matched, but variations of +/-50% are perfectly acceptable for ESR as well.
