[chickenbeef]

Thank you very much!

i'm not done yet, next picture will come to

For lower you're Vdrop when overclocking add caps.
For GPU you need 2.5v caps, MEM you need 4v or 6.3v caps.

When you measure point with multimeter, ground on IO-Shield,
You find points that gives you voltage on caps for GPU, you add there 2.5v caps.

Where you measure on caps near mem chips on backside of pcb, you add 4v or 6.3v caps.

Some examples what i can see on bad quality pics from you :p

[chickenbeef]

Yeah, sorry about the quality. Took them with my phone as my camera died recently :(.

How do you insulate the back of the card by the GPU area with all those caps?

I'm thinking of putting all caps on one end of the card and running wires to the solder points, this will work right? Would make it easier to spread the art eraser too.

[Chiller]

legs of caps need to be as short as possible otherwise no effect.
don't use wire, isolating is no problem, use vaseline (petroleum jelly, dirty stuff) and heat it up, so it melts all over you card like Tin uses it (http://xdevs.com/evga/580c/card8.jpg).
Or you can use Dragon-skin, latex etc......

Or use kneading gum for kids like i do, you can put it everywhere between it.

[chickenbeef]

Aha, I'll go with the vaseline. Thanks again :)

[Chiller]

no problem, don't forget the post results of OC here :p

[BenchZowner]

Vaseline all the way :p

[chickenbeef]

Looks like a nightmare to clean up!

I'll vaseline the graphics card. Mobo on the other hand, I'll stick to art eraser. :)

/I have that same board :D

[Chiller]

industrial degreaser i use for it, then let it dry,
and you have a clean mobo/vga

[BenchZowner]

It's easy to remove.
Take a few big pieces with some tissue paper and some in-between capacitors/slots/tight spaces with a q-tip.

Finally, steal your girlfriend's hairdryer and use it to move the rest of the vaseline off your board ( hot setting, hold the mobo at approx 85* degrees vertically and blow hot air towards the edge of the mobo, the vaseline will melt and flow off the board ).

I can get my stuff clean and RMA-ready in less than 30 minutes.

[Chiller]

i cleaned my GTX580 classy and gtx285 in 20min for the two with degreaser in a bucket lol :p

It's fast away but it's nasty stuff hahahahah

Because I don't live in a humid country, if a couple layers of toilet paper, a layer of LET and some neoprene can't keep a component safe, it deserves to die for being so weak :p

[BenchZowner]

s'up kenny :p

[chickenbeef]

Trying to clock this now under DICE, using a 22k VR and it puts it at 1.4v.

Can't run any benchmark as it's hitting OCP (Voltage stays at 1.4-1.42 during the benchmark but it only goes like halfway through). I couldn't do the cap mod because the electronics store here only sells 16v caps, could that solve it? The caps.

[Chiller]

so put the voltage lower to not hit OCP/OVP, only 16v caps on 12v lines will not help much.

the best thing you can bypass OVP/OCP is zombie mod

[chickenbeef]

The VR is turned all the way down :p

Should I use a higher rated VR?

[Chiller]

yes offcourse, and turn it at max resistance.
then slowly raise it

Also need to know what stock Vgpu is before you start to raise it

[chickenbeef]

Okay, will change it now. Stock is 1.25v

always try first with high trimmer, if voltages doesn't go high enough uses lesser.

try 100k 200k 500k
