    edit.. i found the vgpu 1.18 load, and 1.09 idle with it downclocked...

    thanks

    It appears that on my BFG OC version pins 1/3/11 are already bridged as well. So Id like to see what I get by bridging 2/4. are there any other combo's that may help?


    Also, does anyone know a chain store for a conductive pen? Im getting low and I dont feel like waiting if i run out.... thanks again

    Radio shack has conductive ink pens.

    The answer to your other question is in the previous posts.

    Forgive me for sounding like a noob here.

    Can this be done with a pencil for easy reversal? Also how are you all seeing voltage?

    Edit: Sorry.

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

    and results @ post #73 by dengyong

    No pencil, use conductive ink for easy reversal.

    For voltage check post 90.

    When measuring the voltage where are you pointing the negative on the multi?

    How long should I let the ink dry before installing/running a bench?

    Until you're sure it will stay where you put it.

    If you are going to use ink, measure the resistance between the 2 contacts you bridge with ink - when the ink is wet the resistance is high, and it falls as it dries. Once it's close to a dead short (the value you get on the DMM when you touch the 2 probes together) you can install & power on.

    Also make sure you don't bridge anything you are not supposed to, just the 2 small contacts at each VID position.

    I'm confused do you bridge vid pin 2 and 4 or 1/2/3/4/5/11? Can someone clear this up for me? Also does this work on all GTX 285s or just certain brands?

    1/3/11 are already bridged from factory on a standard card.

    On an EVGA SSC card, 1/2/3/11 are already bridged from factory.

    When we talk about bridging 2/4/5 we are meaning bridge them in addition to the ones already bridged from the factory.

    If you have a standard card (1/3/11 already bridged):

    Standard vgpu is ~1.16v

    Bridging (2) will give ~1.23 vgpu load.

    Bridging (2) & (4) will give ~1.24 vgpu load.

    Bridging (2), (4) & (5) will give ~1.25 vgpu load.

    If you have an EVGA SSC card (1/2/3/11 already bridged):

    Standard vgpu is ~1.23v

    Bridging (4) will give ~1.24 vgpu load.

    Bridging (4) & (5) will give ~1.25 vgpu load.

    If the card is reference design (which I think they all are but I can't be certain) then it should work fine.

    Thank you for the very excellent answer; it is exactly what I was looking for.
