Not sure on my version, (just got the card in the weekend - Raedon 7970), and using Catalyst overclocker to the full 1125 it gets 680khash with GUIMiner-scrypt and small tweaks to the default 7970 high intensity profile.
Runs at close to 80 degrees though with auto fan, fan never goes about 60% or else it sounds like a jet engine - don't imagine this cards going to last too long!
Sounds like yours is running pretty well - I wouldn't worry.
Another point - anyone using Catalyst 13.4? On a clean install with 13.4 cgminer and reaper just crash on startup every time, but work fine when I downgraded to 12.8 version.
That's not too bad for BTC mining. There's not too many tweaks you can do AFAIK for SHA256. Most of the tweaks are for Scrypt mining.clubman said:
I get 650-660MH/s using my 7970Ghz with 1100/1500 clocks.

Using Reaper or GCMiner? Sounds like I'm about right then.
Do you overclock to those specs all the time and run it almost 24/7 - what sort of temps do you get?
CGMiner, it's the best one out there.
Running Catalyst 12.8 on my Windows machine with 7970. Other one is Linux running 13.1.
They are standard overclocked specs from factory and yeah, been running 24/7 for ages.
Temps are usually low 70s.

this is all i have in the bat file below. open case
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cgminer --scrypt -o stratum+tcp://coinotron.com:3334 -u xxxx -p xxxx -I 19 --worksize 256 --gpu-threads 1 --shaders 1792 --thread-concurrency 16384 --gpu-engine 1200 --gpu-memclock 1500
below is just a quick screenshot of it running after for about 3mins , but generally it stays around 680 at 67 and the auto fan increases if the temp goes into 70 to bring it back down

That's a freak 7950 if that's what it is.
Those look more like 7970 specs.
Especially getting the core to 1200MHz and voltage of only 1090mV

And such low temps. WTF!
What kind of card is that :O

RetardedMonkey : I only got this card the other day, im still new to mining and not sure about the voltage setting, see attached picture, adjusting it does not make a impact on the card temp or performance or power input/output not sure whats going on there.
2ds your right I took shaders out and is working the same as before.
Running it on stock I only get 580 ( 1000/1250 )
I few posters in another forum said my motherboard is really good for mining so not sure if that makes any difference?
Also the card is the REV 1.0 version not the REV 2.0 & is Bios FZ1

Ah yes, that's a lot of volts.
Still, that's a monster of a card.

How accurate are the hashrates the pools display on their websites, FC-Geek website is currently showing;
Your Current Hashrate
951 KH/s
Seems a bit extreme...

Some of them are totally wrong.
They estimate your hashrate based on your valid shares.

Coinotron seems to screw me over on those stats, I sit on 550 - 650 and it only shows me as high 100's.
Have to say, I'm really enjoying this mining aspect, even though I'll never make the kind of cash I did/do trading I find it a lot more satisfying having a rig just sitting there generating coins and playing around with the settings/pools etc.
Coinotron shows you your hashrate according to how many shares per second you are doing. so it shows the real rate of your rig.
In shares over a 24h period the 7770's seem to be the most steady for litecoin in my bunch. 7870XTboost are crap for litecoin but great for bitcoin and the 7970's are ok at both but better on bitcoin.

Ah i've been having the same problems with 7870's (MSI) i spent a good 3 hours playing around with settings but couldn't get them to provide any decent number of hashes for scrypt mining.
What I did manage to do is tune them so they were producing hardly any heat... not ideal but at least that is something... it seems that it is still more profitable to leave them litecoin mining than bitcoin mining at the moment anyway.
