680i (eVGA, XFX, BFG...) A1 / D00 Rev. VCORE AND VDROP DONE!

4. You don't need to remove any caps, just add extra on the backside. Red dots for (+), blue dots for (-); try to have as strong solderings as possible, because trough those cap's pins there is alot of current flowing. There are only the Vcore's output caps marked, the +12V extra ones are not really necessary. Let me know where you want to order from and i will give you a few pointers, generally any solid Aluminium capacitor with about 500uF or so will do.

Thanks for the detailed answers, some very good advice about the pots and I think I would be confident to give it a go ! I do take your point about being a beginner, but I am planning phase cooling for my quad, and in any case I like to jump in the deep end !! I can get my hands on an air solder station, so hopefully with a magnifying glass I would be able to get the job done.

Still a bit confused about the other caps though ......

The four +12v ones you have not marked look a bit more straigtforward. You had origonally said these 4 were 2200UF low-ESR , but in your picture they look like 1200uF. It wouldn't be too much trouble to do them. How un-necessary are they ?? I have marked them in green if you want to check them.

My main proiblem is, I can't quite match the red and blue marks you have made on my photo, to the caps on your photo !! Do I need 5 3300uF Rubycon MBZ's or more?? Can you explain exactly how they are wired . From your photo it looks like you have joined the red and blue dots together, then connected one end to the cap, and the other leg of the cap to where the red line is marked!!?? Is that correct ??

Also you have a red and black wire going from one of the points, and there is no cap connected to 2nd set of red/blue dots down on the right hand side.

I have marked the areas in red I am not sure about, on the photo below .....??



Lastly - I am waiting for an RMA board to arrive, when it does I will use it as my test board, so it might be a few weeks before I get started. I will look out the stuff I need first and run it by you before I order !
