Best mining configuration +800khs on AMD MSI 7970 OC

[Duetschpire]

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

I will try those settings tonight when I get home.

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?

your card must be under water or  you are in north pole !!!

Everybody else Don't try this ... 1880 memory

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.

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.

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.
