The VID mod on that 680 gave some mighty strange results. Eventually we said to hell with it, it's getting EPowered.

yeah gpu core voltage kept hitting the 1.45 volt range despite the ViD jumper settings.

Though we did find some interesting results due to other modifications during the normal runs. The Auto overclocking range on the 680's is really quite an interesting beast.

So interesting question here, what would cause a 680 to run 0.75v to the ram after being zombied. Only did the core GPU voltage line. Left the vmem alone.

What vr's should I use for mem voltage and ocp tunning?

Can someone explain how Kingpin put together this setup to achieve 1400MHz without epower and using the stock coolers? Epower is not an option for me as I'm going to run my 680s in SLI and they'll have to use stock coolers for the next month until the rest of my watercooling stuff comes in. Then on go the Heatkiller blocks for the long haul.

They were HW VID-modded reference GTX 680's. They can run 1400-1450, best ones maybe even 1500 or so, without blowing stuff

HW Mods are listed on start of this thread
