So, why Nvidia are not getin' into BTC at all?
Because it would be a stupid idea, AMD isnt even "getting into btc"

They all basically produce 0.6 MH/s per Mhz engine clock speed.

Nice, so at 1250 MHz you should get 750 MHash/s ?

That seems about right. On DiabloMiner on my 7970 at 1125 I get 675.

The bigger question now is : how many reference 7970s ( or the new better binned GHz editions ) can reach 1250 MHz without overvolt ?

I dont get this binned GHZ edition shit. Mines a ref design factory overclocked to 1010mhz, and I got it like 4 months ago. It happy cranks away at 1125mhz at stock volts.

You don't get marketing ?

Cheesy

GHz edition is supposed to make it "cool" to the noob gamers and convince them that 7970 is comparable to GTX 580.

When it clearly isn't ...

Of course it isnt. NVidia totally botched the 580, they'll never catch up to AMD at this rate.

Linux since 1997 RedHat 4
well, clocked near 1300 core. Using diablominer
What was the shares/minute over a 24 hour run?

Doubt it is stock clocks.

Card will soon die unless you got proper hardcore cooling Undecided

I have never got more then 704mhash out of any 7970.

When will see new ati drivers? I made 700-750Mh with my Sapphire 7970,  but I think it can do much more with better drivers, or maybe new version of Diablominer.

PLEASE share how you get 750 because nobody seems to be able to get that much normally !

Thanks !

bronan, I can confirm your memory speed theories.  My 7970 is unstable if I set the memory slower than stock.  My rig crashed 5 times a day until I experimented with putting the memory at the stock speed.  The rule of -150MHz from core clock doesn't apply to this card.  Wish it was like my 5830's where I can set the memclocks at 300.

Haha yes both my sapphire 5870 vapor x went to the usa but where perfect able to run at 0.900 volt 750 mhz on core and 166 mhz on the memory
They are still awesome cards and i think the new owner is very happy with them.
I remember i often bend over towards my computer to make sure they where running fine Cheesy ( so silent )
And yes i could game on them also while mining with no problems ofcourse not with the graphics power of these but still.

Do not get me wrong the 7970 i have now are monsters and i love them but underclock/volt wise they are a pain in the ass they just want speed and more speed Cheesy
So a bit underclocking is possible but not much, undervolting does not work either, so far it seems that the cause of all this is ELPS the advanced power save build into the cards. This far i have not been able to turn it off completely i would like that though so i can proof if my theory is right.

Maybe someone has advanced knowledge at ati bios matter and would like to help find out if its possible to turn it of by flash the bios with a alternative one

looks like the diablo miner is the  best miner to go with

Yes you asumed correct for me and my high electricity costs its allways been the goal to undervolt / underclock at best hash result.
But i also want to keep gaming and yes i want to game when mining for that i reduce the graphic needs in the games to about medium settings, which does not affect my mining at all

So yes i can play World of Tanks at medium settings and the miner does not even show a small bump 

However this far i am very pleased with the new driver set from Amd.
Installed catalyst 12.4 and guess what it runs stable now even at 800-1250 on the core and 800-1550 on memory (min -  max)

To make matters clear as soon as i set the memory below 800 the crashes appear again, that is when mining and using some programs like games, video processing tools and sometimes even with winzip or rar

My cards also tends to crash if the difference between core and memory speed becomes more then 150 mhz again speeding it up does work fine but when trying to lower the speeds the crashes start.

However need todo some more tests with the newer driver and cgminer 2.3.6 to see if i can now go below the previous limits.

This far 800/800 has been the most silent, efficient and coolest miner setting but time will tell (74 c gpu temp).
