Hi all,
I have an old XFX 8800gts with a broken inductor. -- See at bottom of post.
The inductor is near the edge of the board labeled 1R0 (1uH value).

I'm curious whether I should try to replace it with the same inductor value or move up to higher inductance to help smooth the power a bit more.
Any EE's know the answer to this? I assume the inductor and caps near the power input is to keep voltage/current constant at the card.
If I increase the value, will the current be held closer to optimal?

I also want to vmod this card, since it's older and I won't be too upset if things don't go well. I plan to add a pot to adjust voltage.
I don't really have a goal in mind, I just want to see what I can do.
Are there any recommendations, like adding additional caps or adjusting memory voltage also?

I would just solder it back in place, but it is the type with a ferrite core and it is smashed to pieces. :eek: It is more than likely shorted out internally, so I don't think I'll go that route this time. I will get some pics of the actual board today.

I have about 8 years of experience soldering, including SMD and reflow, so that's really not an issue and I have the equipment handy anyhow.

Update:

I started the process by stripping down the card and washing the board with ethanol. The cooling block, fan, and front plate were cleaned in an ultrasonic bath for ~20 min each with ethanol or ethanol/water.
