I have only tried it once, and haven't noticed a climb in performance yet... I doubt I will use it again, unless I can cool everything a little bit more.

PWM has helped me with stability on hitting the limits of my card, but as for anything but pushing it real hard, it doesn't help. Really, if anyone is going to be pushing 1.3v and above with the classy tool, they should be using a DMM to verify the voltages at load.

Where did you buy yours? Your DMM.

Also do you use the evbot?

I do not use evbot. I probably picked it up at home depot? I can't honestly remember because it was 4+ years ago. They aren't all that expensive.

I grabbed 2 off of Amazon and they are great:

I maxed the khz on my 780ti. And 1.3675 i Got stable 1440 mhz. I run alot benchs With the PWM maxed.
My max temp is 41 With This settings.
And Real voltage is about 1.480 With PWM maxed tongue.gif

So, is the PWM control just like changing the BCLK on the CPU? I think my mother board is crippling everything I can do right now. I can't wait to change it out and see what happens.

If you clock your card and the computer shutdown. You Can ADD more PWM. And go further. PWM is something about how good voltage is controlled. But higher PWM more heat. With 400 Khz you should be more than enough on water to reach card limit.

Im not 100% sure. But its how Quick the voltage is controlled. Low khz With High clock. Then the card deliver the correct requested voltage to slow and shutdown.

Nah, I have had to go over 500 KHz on my cards to stabilize 1525 MHz clocks and higher on water.

I will test this out at the beginning of the month. I have all of my cards competing in a folding competition, for the next few days. I will give it a try as one test shuts my computer down every time. I have barely messed with PWM, as I have no idea what it does as of yet.

Hopefully running Dual PSU helps feed these beasts.
