sorry nickless no pencil but all it takes is silver conductive paint to bridge a vid pin

if you bridge vid pin 2 and 4.. take a look at post #71 by cryptik
and results @ post #73 by dengyong

Yes silver conductive paint is easily removed with some isopropyl alcohol or acetone on a Q-tip. If you use acetone be careful what you get it on, it is quite a strong solvent, but I have not had an issue with it yet.

Napalm, would you mind measuring the shader voltage on your cards? I use one of the small caps a centimeter or so towards the rear of the card from the shader chip (on the back of card) - I'm pretty sure this is the shader voltage anyway.

I made it, I bridged 2 and 4 pin with silver conductive paint and now I have 1.22v Vcore and 2.12v Vmem. Thank's a lot to NapalmV5, dengyong and CryptiK .
Get some test now

hmm, i have an eVGA SSC - the first three from the left already have resistors on them. thats all though, 1,2 and 3 - the rest are blank.
would bridging set 4 help any you think?
PC-A04 | Z68MA-ED55 | 2500k | 2200+ XPG | 7970 | 180g 520 | 2x1t Black | X3 1000w
actually, looking again - 1,2,3 and 11 are resistored already.
PC-A04 | Z68MA-ED55 | 2500k | 2200+ XPG | 7970 | 180g 520 | 2x1t Black | X3 1000w
1/2/3/11 is normal for SSC version, this gives ~ 1.23vgpu/2.15vmem. If you bridge 4 you will get a little extra voltage. I currently have 1/2/3/4/11 bridged and I'm experimenting with other arrangements.

this is a great thread. i thank you guys for your willingness to share!
your efforts are appritiated

Yes for me bridging 4 gave me an extra 0.01v on both vgpu & vmem.

Thanks for this guide guys ,well done. I would like to know where to measure v.core and v.mem ? where are the points to check with DMM ? i just got an xfx GTX 285xxx and i would like to measure my stock voltage and try this mod after testing the card on stock volts.
Any help and guidance will be greatly appreciated.
chispy.

^ dengyong/cryptik - thanks
nickless - looks like you got it figured out thanks to cryptik/dengyong
if you guys also bridge vid 10 you may get 1.24-25vcore
if you guys want ~1.26vcore which is the most doable right now/~2.17vmem.. just solder a 22k resistor from ground to one of the points @ vid 2
your welcome guys
forget credit.. sharing is more rewarding

I measured 1.18v at both caps to the right of where 'C1277' is written on the PCB. I may be wrong though this might not be shader voltage.
Also I just bridged VID 10 (as well as having 1/2/3/4/11 bridged) and got no change in voltage. Then I removed VID 4 leaving 1/2/3/10/11 bridged and got 1.21v load and a BSOD at stock clocks. No idea what caused it but I'm removing VID 10 and hope stability returns.

If 2/4/ give 1.22-1.23v, can I try 2/4/10 for some extra vcore?
[off] Are commands for GTX 285 in nvflash the same like GTX280:
For Normal Flash: nvflash -5 -6 newbios.rom
For Forced Flash: nvflash -4 -5 -6 newbios.rom [off]

sorry about that.. after so many combos..
i had:
1/2/3/4/5/11
1/2/3/4/5/10/11
1/2/3/4/5/9/10/11
many others
i dont remember exactly how i reached ~1.25vcore
probably vid 5 so: 1/2/3/4/5/11
im gonna confirm that in a bit..
no just 1/2/3/4/11
let me see if i can get it ~1.24-25vcore
yes same commands

[QUOTE=CryptiK;3640847]I was going to reply to your PM but it looks like you have it sorted now.
Hey Chispy, here's the points I use. Red = vgpu measure point, green = vmem measure point.
QUOTE]
Thanks a lot Cryptik , appreciate your help bro. Testing today i will let you know how this mod goes on my card.
chispy.
Don't apologise, I'd been bridging things experimenting myself, and was minutes away from bridging VID 10 of my own accord.
I tried 1/2/3/4/5/11 and it didn't cause any change in voltage for me. I'd like to get 1.25v, I think that would be a good balance between heat & speed.
No problem mate, hope you get some good results with it.

i just redid 1/2/3/4/5/11 and @ startup its ~1.24vcore and @ load ~1.25-26vcore
next ill try 1/2/3/4/5/6/11
edit: startup @ 1.23vcore load @ 1.25-26vcore

lower resistance @ the 1kohm resistor dac/ref might lead to the back of the card lowers vcore.. higher resistance doesnt allow os boot @ 1.33vcore
suggestions?
cryptik.. what you think about the 1k resistor on the back.. its the 1st resistor at the bottom right of the vid pins.. the 26.6k resistor is the 2nd one
Interesting, what do you get with just 1/2/3/4/11 ?
