I'm interested...

I've PM'd another modder who knows his stuff better than I do to see if he can confirm it.

Yes, you can do a VR to pin 4 (FB), but you can only go up .05-.1v at the most before this IC will trigger OCP. This is why the big boys are going with the VID mod. If you're happy with ~.05v, VR to FB will work.

Repost from the BIOS thread since I'm not sure where is the best place to post this.

For those who have the Asus DCII card and have done the VGA hardwire mod, is there any way to prevent throttling and voltage fluctuations beyond 1.485V?

I'm using the TOP BIOS on my DCII OC card and when I push to 1476mhz on the core @ 1.48V, the card throttles down occasionally in the Unigine Valley benchmark so I was wondering if there was anyway I can mod the BIOS to prevent that. The card is watercooled so the temps are below 60C and there is a fan blowing directly on the VRM heatsink so that stays below 70C also. I'm not hitting the 159% TDP limit either.

hi guys, typically what's the clock speed you can get from unlocking voltage on GTX 670? I have gigabyte GTX 670, and so far I'm stable at 1322-1333 MHz core and 7208 MHz memory. I'm currently looking into water cooling, so perhaps I'd voltage unlock my card later. smile.gif
