I dunno about that - to me it seems like your score is high for crossfire with 7970s at 1100 core.

i was wondering, what is the best bench for checking stability (without being have to check for artifacts or just seating near it) and best represents game stability? (i.e. doesn't require to buy a game)

Has anyone tried undervolting their card with stock clocks? Thougth of doing this today to lower my temps a little bit, mainly to see if my flickering shadows+ some other artifacts are due to temps. Seems like a better option than overclocking at the moment because my card seems to be barely stable at 1.1ghz @1.17V (stock voltage). The highest I've seen my temps is 69ºC. Could this be a reason for artifacting?

Is your score with all three of your 7970's or just two? Also, I had my CPU at stock (3.3) so that might account for a lower score as well.

Finally, I was able to run my first 7970. I'm running my cpu stock since I'm testing an Asus mb I have for sale.



Gpu score is awesome compared to my old 560 448 and 6970 Lightning!

Interesting thinking.gif I will have to take another look at my settings and run it again.

By the way, do you have a recent 3DM11 result with your two cards at that OC?

Here is the result I got the same day I ran Heaven:
http://www.3dmark.com/3dm11/4304978

P14746

I suspect 3DM11 details might shed some light on where our score differences are coming from

How common is the capacitor/vrm whine???

Its very noticeable when I launched a game.

It's quite common in high-end cards. Should calm down a bit over time.

Hmmm, the card is a couple of months old but the guy said he was having crossfire issues w/ the drivers and pulled it a month ago.

I'll keep an eye (or ear biggrin.gif) on it. i have another one coming in to compare it (its 6 months old).
