DC II 680

Have my card vmodded, and was wondering what the pro's here think about safe voltage levels specifically for this card, and also PLL voltage.

I've been running 1.4V to get an idea of how high I can go, and I'm topping out right around 1430 MHz. It's watercooled and rarely passes 40C on the core. VRM's are floating anywhere between 55 and 70C, depending on what I'm running.

Should I stick to a limit around 1.4V on core? Do you think upping my PLL voltage will do anything? I'll probably try anyway, but wanted some advice on what you all think. Thanks in advance

I'd stay short of 1.5V ( even if it's just by hair ).
Usually on air/water these cards stop scaling from a point and on.
For example my worst card maxed out on cold air at 1.31V.
Higher voltage, even 1.45V doesn't add up any MHz at all.

1.5-1.6v for 680 should be ok, but don't know exactly, i don't have DCU 680

Thanks for replies guy. I've maxed it at 1.475 for now, not getting much more over 1.4 anyway.

How about PLL volts? Think that'll affect it? Just wondering, before I try
