I remember a thread on XS where you discussed this with someone else.

I feel the extra capacitance helps more then extra noise/resistance hurts. I've found extra capacitance always helps on unmodded GPU's.

I only ran a rough test without them. And i reached similar clocks with and without them. So i don't think that they helped much. I got roughly 5 extra MHz out of them. I will have to try soldering them directly and see if i can find some better gains.

I agree.. i cant ever say that I have had a GPU that didnt benefit from capping..regardless of how "backyard" the method of installation was.

@ the OP-
I noticed..that i need to look a 2nd time occasionally

Ohh i didn't realize they were on the memv circuit. No wonder my memory has wonderful clocks. Where would the GPUv places be that i should put capacitors on?

i looked a 2nd time and I dont know what i was thinking..those are on the right SMD's for GPUv.. the pic looked different to me the first time ....

*You can use some needlenose pliers to carefully bend the legs of the caps downward..it will help them 'lay' down a bit more, and provide better clearance once installed direct to the SMD caps on the PCB.

caps on your first ever volt mod, way to go!

Ok so i tried putting the capacitors directly on the board. It didnt make a difference on my clock speeds. But i think it may have helped a bit with getting my current clock a tiny bit more stable. I think my temps are really what are holding me back.

815MHz/1400MHz Idle: 42c Load: 75c

And here are some pictures of the change for good measure. Enjoi

Be careful Gouzlan. V'modding is addictive. Before you know it, you'll want to V'mod your 480.

Looks like you got a steady hand for it.
