What is the best mining settings for 7970? Please pose driver version used, SDK used, and the various cgminer mining options. Current setup: Old gigabyte Intel 775 mobo, 4 PCI-E slots. Win7 x64 Intel Quad 6600 from back in the good old days.
Edit: added more info for my setup

Catalyst 12.6. Don't install the SDK because the drivers already include the latest OpenCL drivers. I run 1200/685 @ 1.174V. Generates ~720 MH/s. I run DiabloMiner.exe -v -w 256.

BLAH! Judging by your 'L33T GAMER' Sig, I am not sure if you are qualified to answer his request. Think MINING, NOT Gamer/Miner compromise. 11.12 7970 Release Edition using included SDK....FTW ! (regular 11.12 will not support 7970, check your reference card driver CD ) 12.x drivers blow dog (for Windows miners anyways). Try run more than 4x 7970s and you will see for yourself.

Also, OP.... You have essentially just asked us "Which tires are best for a Chevy" ?
Windows ? Linux ? Dedicated Miner ? Desktop ? Gaming Rig ? How many cards ?

Win7 x64, dedicated miner, one card now. The best info I've seen: Use 12.2, with SDK 2.6 (not the included runtime with the driver). Use AB 2.2.1 to undervolt, and then use CGMiner to OC / manage fan control. That's about it.

You obviously never got that info from someone running more than 4 cards in a machine under Windows.....but then again, what would I know. I only have 15 7970's running combined in 3 rigs.

Ad-hominem attacks are not effective on advancing your viewpoint. If you believe 11.12 is better, post numbers to prove your point, not attack the person.

Here's my number - FIVE .....as in, the number of 7970s in a single Windows Miner that 11.12 allows me to run. 12.x is pure FAIL for more than 4 cards.

Would you point to where to download 11.12 drivers for 7970? I googled and didn't really find it. Or would regular 11.12 driver work? Also if you don't mind posting your cgminer settings, and core/mem/volt settings. Thanks! Give me address for donations

If you're just using one card for now, use CCC 12.3. I have 4 separate 7xxx cards going in one rig without any issues. Haven't tried more than 4 though.
As for settings:
CGMiner intensity: 7 vectors: 1 worksize: 256 kernel: diablo
MSI Afterburner Core voltage: depends on your card (I leave mine at stock voltage) Core clock: 1100 MHz Memory clock: 170 MHz Fan speed: 85%
This will yield 650 Mh/s.

OP states that he's running one GPU in the 2nd post We're not even sure he has enough PCI-E slots for 5 cards. I'd like to see some hash rate vs MHz numbers posted by your 11.12 setup (as I'm not about to install the drivers and ruin my perfectly great 3x7970 setup on 12.3). I'll bet AMD has made some improvements to the OpenCL drivers that make 12.3 a better choice for mining than 11.12 in a <5 GPU scenario.

Will try 12.3 tonight, since the mobo only have 4 slots for max of 4 cards anyways. So use the SDK with 12.3?
I was running 12.4 with the included SDK, and it runs at 460MHash at 1125Mhz core.... which is totally unacceptable!

Correct. 12.4 and on have been nothing but a headache with mining. You have to use a dummy plug in order to get the correct hashing speed which is dumb.

No SDK with 12.3, just use the OpenCL drivers that come with 12.3.

Once i found the benefit of undervolting. I will never run my cards flat out anymore, not unless btc's are 30 a piece!! Minimizing electrical costs is such a short-sighted goal. The main goal should be to maximize profit. Even if you paid 10c/kwh, it makes sense to run at stock volts and max out the GPU. For your particular system: 3300MH/s generates at current difficulty and $5.2 exchange rate: $3957.24/yr 2750MH/s generates at current difficulty and $5.2 exchange rate: $3297.72/yr 1.44 kW * 24h/day * 365 day/yr * 0.1 $/kWh = $1261.44/yr 0.83 kW * 24h/day * 365 day/yr * 0.1 $/kWh = $727.08/yr 3300MH/s profit = $2695.8/yr 2750MH/s profit = $2570.64/yr As long as your power supply can handle it, it makes sense to run stock voltage and overclocked.

I used intensity 11. Running at 673MHash. Default volt, 1125 core, default memory. How do I reduce the memory speed? I tried the slider in AB, but it doesn't change at all. I read there's a special file that I need to change in AB, what would that be?

I read there's a special file that I need to change in AB, what would that be? Intensity 11 is fine, but seems to cause CPU bug with multiple cards. So I leave it on 7 with my miners. You have to go into MSIAfterburner.cfg and change UnofficialOverclockingMode = 2. When you open AB again, it will ask you to accept, click Yes. Then you should be able to lower your memory speed and it should stick. If you want to lower it even further, close AB, go into the Profiles folder (MSI Afterburner\Profiles) and delete anything that starts with VEN_. When you open AB again, it will ask you to restart to detect default settings properly, click No.

I agree with you. Usually I don't care about the undervolt. Cause I know the calculation would be kind of close, and I just got lazy. Woah Now I'm confused! You're increasing your electricity used by 74%. That extra power only gives you an increase of 20% in hashing speed. Your efficiency goes down from 3.31MHs/W to 2.29MHs/W. And yet you still manage an extra $120 profit? I'm gonna say that only works when your $/KWh is low. Lets try again at 15c/KWh... 3300MH/s generates at current difficulty and $5.2 exchange rate: $3957.24/yr *Stays the same* 2750MH/s generates at current difficulty and $5.2 exchange rate: $3297.72/yr *Stays the same*
1.44 kW * 24h/day * 365 day/yr * 0.15 $/kWh = $1892.16/yr *50% increase, dur* 0.83 kW * 24h/day * 365 day/yr * 0.15 $/kWh = $1090.62/yr *50% increase, again*
3300MH/s profit = $2065.08/yr 2750MH/s profit = $2207.10/yr *~$140 more profit*
So at $0.15/KWh, it's more profitable to lower the voltages/hashes. OK...I feel less bad for maximizing efficiency now, because I am not getting 10c/KWh

Lets try again at 15c/KWh... 3300MH/s generates at current difficulty and $5.2 exchange rate: $3957.24/yr *Stays the same* 2750MH/s generates at current difficulty and $5.2 exchange rate: $3297.72/yr *Stays the same*
1.44 kW * 24h/day * 365 day/yr * 0.15 $/kWh = $1892.16/yr *50% increase, dur* 0.83 kW * 24h/day * 365 day/yr * 0.15 $/kWh = $1090.62/yr *50% increase, again*
3300MH/s profit = $2065.08/yr 2750MH/s profit = $2207.10/yr *~$140 more profit*
So at $0.15/KWh, it's more profitable to lower the voltages/hashes. OK...I feel less bad for maximizing efficiency now, because I am not getting 10c/KWh You're right, at 15c/kWh it is profitable to undervolt. May I ask where you live that is so expensive? Southern Maine, with residential prices. It's gone down from about 15 1/2 to 14 1/2 over the past year.

Noise too ! Electromigration too. Anyone that is NOT undervolting their GPUs with the incoming army of FPGA/ASIC and 25 BTC reward is only kidding themselves or being lazy and losing out $$$. Maybe free power people ... but somebody is paying for it !

Once i found the benefit of undervolting. I will never run my cards flat out anymore, not unless btc's are 30 a piece!! Minimizing electrical costs is such a short-sighted goal. The main goal should be to maximize profit. Even if you paid 10c/kwh, it makes sense to run at stock volts and max out the GPU. For your particular system: 3300MH/s generates at current difficulty and $5.2 exchange rate: $3957.24/yr 2750MH/s generates at current difficulty and $5.2 exchange rate: $3297.72/yr 1.44 kW * 24h/day * 365 day/yr * 0.1 $/kWh = $1261.44/yr 0.83 kW * 24h/day * 365 day/yr * 0.1 $/kWh = $727.08/yr 3300MH/s profit = $2695.8/yr 2750MH/s profit = $2570.64/yr As long as your power supply can handle it, it makes sense to run stock voltage and overclocked. I agree with you. Usually I don't care about the undervolt. Cause I know the calculation would be kind of close, and I just got lazy. Woah Now I'm confused! You're increasing your electricity used by 74%. That extra power only gives you an increase of 20% in hashing speed. Your efficiency goes down from 3.31MHs/W to 2.29MHs/W. And yet you still manage an extra $120 profit? I'm gonna say that only works when your $/KWh is low.

Maybe free power people ... but somebody is paying for it ! Watercool for the noise and the fan life. Electromigration isn't a factor when you consider these cards will be obsolete far before that becomes an issue. There are still parts of the US that pay less than $0.06c/kwh so this will still be competitive with FPGA, even after 25 BTC reward drop.

Just ordered 3.6GH/s worth of FPGAs a few days ago. When I started mining way back March last year, a 5670 could earn ~3 BTC/day and electricity was 17c/kwh.

Digging this thread back out from its June 6 grave.
Any more miners with settings, mhash results and watts to report?
I'm currently using an ASUS directCU II (non-TOP) pulling 673mh/s at stock voltage with 1150 GPU clock and 450 memory.. Just starting to play with optimization so input and other experiences would be great.

If you're just using one card for now, use CCC 12.3. I have 4 separate 7xxx cards going in one rig without any issues. Haven't tried more than 4 though.
As for settings:
CGMiner intensity: 7 vectors: 1 worksize: 256 kernel: diablo
MSI Afterburner Core voltage: depends on your card (I leave mine at stock voltage) Core clock: 1100 MHz Memory clock: 170 MHz Fan speed: 85%
This will yield 650 Mh/s.
I used intensity 11. Running at 673MHash. Default volt, 1125 core, default memory. How do I reduce the memory speed? I tried the slider in AB, but it doesn't change at all. I read there's a special file that I need to change in AB, what would that be? Intensity 11 is fine, but seems to cause CPU bug with multiple cards. So I leave it on 7 with my miners. You have to go into MSIAfterburner.cfg and change UnofficialOverclockingMode = 2. When you open AB again, it will ask you to accept, click Yes. Then you should be able to lower your memory speed and it should stick. If you want to lower it even further, close AB, go into the Profiles folder (MSI Afterburner\Profiles) and delete anything that starts with VEN_. When you open AB again, it will ask you to restart to detect default settings properly, click No. If that method dosen't work,just copy & paste the info below over the info in the MSIAfterburner.config file under this section-[ATIADLHAL] BTW,you can open the config file with notepad EnableUnofficialOverclocking = 1 UnofficialOverclockingEULA = I confirm that I am aware of unofficial overclocking limitations and fully understand that MSI will not provide me any support on it UnofficialOverclockingMode = 2 AccessibilityCheckingPeriod = 0

Gah, I hate you. 750w+ for 2x 6870's and 2x6970 getting 1340mh/s. (yes, its currently profitable) OK, time to figure this crap out. That rig is my biggest moneymaker, but also the most power-hungry. I'll chime in more once I get my 7970 + 6950 mining tonight on a different rig.
