Am I already too late? With the latest news about the price, I am a bit disappointed that I worked for this.
The profitability is gone already? Popular & premined coins get dump-destroyed on the market within 24 hours now? Locusts.
Anyways, this is what I found out.
Please

Optimized 7970 xfx, 7850 powercolor.all comma values are 7970,7850, ie. --gpu-memclock 1700,1475 means the 7970 gets MC=1700Mhz"SUPERHOT" = hot, loud, wasteful, strenuousIn "SUPERHOT" mode
I get 82% of my normal scrypt khash/s in "HOT" mode.
Ultracoin 863 khash/s (7970: 591khash/s, 7850: 272khash/s).
With an efficiency of 2.02 khash/s per WattTotal (incl mobo&CPU).
The 2 GPU system (incl mobo) uses 428 Watts, that's 79euros per month.
Temp = 74C, Fan is at 66%. Trying it now, it's already going on my nerves.

"COOL" = cooler, silent, efficient, conservingIn "COOL" mode
I get 77% of my normal scrypt khash/s in "COOL" mode.
Ultracoin 703 khash/s (7970: 458khash/s, 7850: 245khash/s).
With an efficiency of 2.51 khash/s per WattTotal (incl mobo&CPU).
The 2 GPU system (incl mobo) uses 280 Watts, that's 52euros per month.
Temp = 68C, Fan is at 34%. Really quiet, will use that for sleeping.

Try it, it's worth it. Saving 148Watt = 27euros per month. Plus: Less polution, a better conscience, and probably longer hardware life.

www.tiny.cc/drakointip Thanks, even a bit of coindust helps me a lot!
Or in [UTC] here please UQ3eqjGqBycgLKuaMeA6kKnoTHp4eENYuo.If you want to understand more about this, visit this thread, it's all documented there:
https://bitcointalk.org/index.php?topic=395004.msg4500529#msg4500529* How to enable undervolting for cards which are volt locked.
* How to BIOS flash
* efficiency = khash/s per GPU-Watts
* lots of measurements
* compared factory settings, my undervolt BIOS, TheStilt BIOS, my undervolted TheStilt BIOS.
* less khash/s can actually make you richer (if it saves you Watthours) depending how profitable a coin is
Happy mining!

P.S.: Let's spread the word, imagine the altcoin network starts saving 1/4, 1/3 or even 1/2 of electricity.
