yes, i use the 7970 for mining too.

[shellbunner]

I use 4 7950's and 1 7970. All undervolted and not overclocked.
Tempting to pick up a couple 7990's now that AMD dropped the price massively!

BTW - what are you people USING to make such high HASH power for Scrypt mining?

12 x ati 7950

using this:

Code:

#!/bin/sh
export DISPLAY=:0 GPU_MAX_ALLOC_PERCENT=100 GPU_USE_SYNC_OBJECTS=1

cd /home/darianc/cgminer

./cgminer \
        --scrypt \
        --failover-only \
        --no-submit-stale \
        --gpu-engine 1125,1150,1150 \
        --gpu-memclock 1250,1250,1225 \
        --shaders 1792 --thread-concurrency 16384 \
        -w 256 --lookup-gap 2 -g 1 -I 19 \
        --temp-target 80 --auto-fan --auto-gpu \
        -o http://192.168.1.10:22222 -u darianc -p x -s 1

I tuned  --gpu-engine and --gpu-memclock for each of the twelve cards over a few weeks.
They range from 1125 to 1150 and 1225 to 1250 respectively.
I have no voltage config due to running on xubuntu.

12 cards + 4 motherboards uses about 3800 watts in this config.

Wow, $629 for a 7990! I had no idea the price had dropped so much. Just curious what settings you are using on your 7970? I have a buddy that bought 2 of the Sapphire Vapor-X cards, and we can't get them to run as fast as the 7950's. They sure are power hungry though.

WOW - That's bucko $$$ on vid cards.

Hey MobGod - you get that compile error squared away?

finally yes now i just need to get the explorer back up i do have a pool that should be fine if anyone can test it also

Best we were able to get out of the 7970's was 550 kh/s, which I thought was very strange. I have Gigabyte, MSI, and Sapphire 7950's, both the Gigabyte and MSI cards will run 640 to 660 kh/s with the core undervolted to 1.050 @ 1050mhz, and memory @ 1400mhz. The Sapphires seem to reach their limit at around 610 kh/s. Thanks for the info, we will give these settings a try.

[shellbunner]

Multipool is getting us!!!! Hash was last at 1464 mh/s!
I'm hoping there will be lots of cheap buys in the near future!
Got my BTC ready!

with the right settings my sapphire goes up to 720 khash/s

Wow that is a lot cheaper, this card was 999 only a few months ago without any games, now it comes with 8.  To think I almost bought this then.  As for power usage, I've read it uses far less than two separate 7970s, however it will hash slightly slower (~100 khash).  Also, this card is the older version of the newer line of 7990s.  There are some newer versions:

Hey MobGod - you get that compile error squared away?

I have a block explorer running at: http://mega.rapta.net:2750

[Lauda]

Keep up the good work Kimoto!

[gr33k]

Man - everyone seems to have righteous GPU's compared to my pathetic Dual 5770's

That's why I figured I'm better off setting up a pool 

Speaking of which - the pool appears to be working great!

We've solved 9 blocks (mainly when we have large HASHers in) and counting (with about 2MH/s only so far).

Jump in and mine some MEC if you have some HASH to spare

Hey Rapta! Happy to see your block explorer is back up.

I noticed that the links were initially working (from mmcfe last block's found) when I directed the link to your block explorer. Then, it seems like you may have added another coin (or something) and the look-ups were failing.

Not sure if you simply reverted back to the way it was again, but it's working now.

I would setup my own block explorer - but the hard drive space it takes up is quite considerable. This prevents me from putting it on my VPS, and refrains me from loading it up on my VM servers. The block building process is also amazingly long.

I might still do it just to have it and put it on my pool, but meh - Since you have yours up - this puts it low on my priority list right now

Basically - thanks buddy

Please hook me up... What settings are you using? I have seen over 800 kh/s as the converted hash rate on pool sites due to submitting a bunch of shares quickly, but never been able to get that kind of speed from the card itself.

No problem!  I had to throw some more memory on the box, it was randomly throwing 500's when it was swapping to disk.  Should be good now .

Oh, I still miss the easy backup function from two versions ago. Any chance of seeing that again? If the function is still there it's nothing more then a gui addition?

Mike's wish has been granted! Updated to 0.8.994D on first page!

Thanks for this from me too.
maybe a little statement from you about the progress of the integration  from the zerocoin lib into MAGACoin?
Thank you so much....

Wow, thank you very much, dr Kimoto! Such a little but handy feature

Man - everyone seems to have righteous GPU's compared to my pathetic Dual 5770's

I have a 7950 with a decent hashrate, up to 600KH/s, but even that is practically useless at higher difficulties. And only with --no-adl, otherwise I get blue screens when I stop or restart cgminer.
And a 7790 that does a little over 200KH/s. Fairly cheap, those kind of cards. Especially in comparison to the real beasts
Also an AMD APU, A10-6800, but I'm not getting more out of it then 26KH/s. Odd, since the A10-5800 does almost twice that. But both are really just a waste of electricity when it comes to mining.

Err... "Time Since Last Block:   12 hours 10 minutes 19 seconds". I'm not too sure if that's good?
