now where are we going to find power supplies with enough 8pin connectors!
If you put 4 of these in a mining rig, you need 12 8pin connectors!

If there is no traction this morning, I probably will just use it myself. Plenty to buy on Amazon.  i'll take it if you send the code first. PM me. |

good thing i pay 10c per kwh

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? |

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. |

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!

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 |

Would you post where I can download 11.12 for 7970?
Do you mind posting your Cgminer settings?

The best info I've seen: Use 12.2.....
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? |

GPUs can run at close to 105C. They won't die at 103C.

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. |

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

Still looking to sell this, all offers were unresponsive. Don't contact me and waste time if you are not buying, thanks.
check your PMs. Due to the number of red flags on your account, would you ship first? |
