I prefer Asus but bought Gigabyte because the Asus cards were sold out.

Code:

start /D "C:\cgminer" cgminer.exe --scrypt -o coinotron.com:3334 -u Worker.1 -p x --thread-concurrency 8192 -I 13 --lookup-gap 2 --worksize 256 -g 2 -d 0 -d 1 --gpu-memclock 1600,1600 --shaders 2048 --gpu-engine 1050,1050 --gpu-fan 60,60

do you undervolt your cards? or keep them at stock voltage?

That's a really interesting topic.
I am about to buy a Gigabyte 7970 GDDR5 GV-R797OC-3GD. These are the only ones in stock unfortunately.
Is there anyone with experience with them?

as far as i know GIgabyte is hardware locked on voltage, so your OC is VERY limited to small increments... However I think you can flash the BIOS on a 7970 with a diff firmware to unlock it but im not sure... thats why im staying away from gigabyte ... on the otherhand my 7950 that is supposed to hit 582 MAX OC ... im getting about 650khs with 1025 core and 1400 mem.

But Im looking at the sapphire...

I have the GV-R797TO-3GD, and they're really great cards. The triple fans are better for an open-air case, or a case with plenty of airflow. If your case has bad airflow, the temps will show it more than a stock cooler. But with the proper airflow, you can get some pretty good temps.

Mine OCs from 1100MHz to 1200MHz with no problems. The early ones were also unlocked voltage, so you might get lucky.

I'm looking for voltage unlocked 7970s as well since they're great for mining alternate cryptocurrencies like LTC.

Im looking to buy 7970's to build mining rigs for ltc... which brand or company do you recommend? and why?

I am going to be overclocking so voltage unlock or unlockable is a must...

Thanks!
