best mining settings for 7970

[chungenhung]

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.

Installed 12.2, then install SDK 2.6. Start cgminer, it says all devices disabled.

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.

I tried finding drivers 11.12 for 7970, but can't find it. Can you point me where to get it?

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.

dont bet on amd making any 'improvements' . Personally, once a get a set of drivers working. i don't touch anything.

This following setup is using the beta drivers from amd website about week after launching the 7x cards.  don't know the number;

MSI GD70 mobo
SS1250 on 4cards
SS650 on 1 card
phenom 6core
4gigmem
westerndig 500
win 64

Once i found the benefit of undervolting.  I will never run my cards flat out anymore, not unless btc's are 30 a piece!!

[chungenhung]

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.

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.
