Mine is stable as, been mining that way 2 weeks before I posted this, and no I don't live in the North Pole LOL I live in Australia and yes it's winter now, but temp are around 20-25 C° during the day. I have an extra side fan, nothing more nothing less. No over volting and no water cooling... My RAMs are 1800mhz gold plated, so if I push em to 1880 isn't a big deal.

The most stable setting for me gave a solid 722 with 1025/1500 on 1.1v for 2.842519685 Kh/W

Next level up gave me 733 Kh/s with 1040/1500 on 1.1v for 2.841085271 Kh/W but found it a bit unstable.

1070/1500 gave me 755 but found it unstable and I'm sure the Kh/W was worse.

You can push these things higher but should consider the cost of doing so...at least for 24/7 mining.

I'm getting 744Khash/s using:

--thread-concurrency 8192 -I 13 --lookup-gap 2 --worksize 256 -g 2 -d 0 --gpu-engine 1080 --gpu-memclock 1500 --shaders 2048  --gpu-fan 65


I don't know why you would take so much risk for a few percent extra.

Is that stable?

In other words, does it stay at 800kh/s average a few minutes after you launch cgminer or does it drop back down again?

hey guys, I've been trying to get the 700kh/s on my 7970 for few weeks, last week I was finally able to break the 800kh/s mark with 1 gpu using cgminer. below is the config and the link for the photo.

Here's the best cgminer configuration for 7970 GPU

cgminer.exe --scrypt -o stratum+tcp://pool.com:port -u user -p password --shaders 2048 --thread-concurrency 8192 -I 13 -g 2 -w 256

the screen shot will also show you the OC settings in AB for MSI 7970

if this works for you (which it should) and you're getting 100-200kh/s more, please consider donating  Grin
