Received for Xmas an MSI 7970 Lightning Ghz Ed

[Paratus]

Powertune +20%

1200 mhz core

start at 1.275v (sounds like a lot but the card is built like a tank and can handle 1.35 and beyond). Play an intense game for a bit or run a benchmark like the AMD Leo Demo and monitor temps and check for artifacts. Hopefully and likely you are stable.

work you voltage down from there until you reach instability and bump it back up a notch or 2.

Ram can almost definately set and forget at 1600mhz.

1200/1600 will give you a monster card and not be beating on it very much.

What is your cards Asic score? Do you know how to check that?

Load up GPU-z and right click on the top of the app, if you do it on the words (techpowerup) it'll work. A menu will pop up, scroll down to "Read asic quality" and click that. It will give you a score % number.

Thanks!

Am using Catalyst overdrive or the MSI afterburner?

I also just checked the ASIC quality - 67.4%. Is that Good or bad?

I'll play around with the card a little tomorrow.

it's just fine

Afterburner

ASIC quality: 60.7%

It'll do 1300mhz with 1.350v, but for a daily overclock I run it at 1200mhz at 1.268v. It'll do 1125mhz on the stock voltage as well.

As for temperatures I've yet to see the card hit 60 degrees. Just finished a couple of heaven benchmarking runs and the gpu and vrm temps were 58 degrees, and the memory was 54 degrees. Guild Wars 2 is my main game and the card never exceeds 55 degrees with supersampling on.

Edit: Fan speeds left on auto for the runs.

that is just like one of mine.

60% asic

1200mhz takes 1.274 although I didn't really try 1 or 2 ticks down but I knew 1.26 wasn't cuting it.

1300mhz @ 1.35v aswell.

 

[TheNefariousOne]

1.35v wouldn't be safe for 24/7 would it? I know the power delivery system built like a tank but the gpu chip itself would degrade from too much voltage correct?

This card does not get hot.

I downloaded the AMD Leo demo & the Heaven benchmark. Highest temp was 58C. This is non OC'd and in my thermally challenged case. My 5870 would hit mid 70s, same setup.

Heaven ran at 43.1 @ 19x12 & 8X AA everything maxed and the card at default.
