Thanks, mine2mind112, I have tried your suggestion:
When I lower the Memclock to your 960 MHz, the hashrate falls to 272 khash/s
Are those really your values?
What is the exact name of your GPU card?
What are the other settings (thread-concurrency, etc.)?
My cgminer 3.7.2 shows WU:584.1/m
I measured your settings, and they result in 128W above the base power usage (when the card is (d)isabled). That's a lot less power than my 240W. Your 272khash/128W = 2.13 are not too bad, really. But still 26% below my best performing settings.
But you give me an inspiration. If the rig itself doesn't use too much (which in my case it does), and you put enough cards into one rig, it might actually make sense to underclock cheap cards; get out much less coins, but also use much less electricity. Perhaps with colder temperatures there is a sweet spot better than my 2.88 = khash/Watt? But if the GPU cards are too expensive to buy, that would not make sense, because then you want a highest as possible hashpower.
So: Your settings inspire to optimize for someone with VERY high electricity costs, e.g. on Tonga, or the Solomon islands ( https://en.wikipedia.org/wiki/Electricity_pricing ) - but who gets computer hardware for free

I agree that would be nice temperature and fanspeed - but at 272/691 = 39% of my current hashrate - no!I suggest try value like these....I'm pretty happy with them.....temperature and fan are quite and power usage is about 180W x card.
Voltage is ok on my cards but on yours could be different .....you have to try go down with Voltage until it doesn't work anymore.
I suggest using MSI afterburner to find best setting and yhen flash them with atiFlash+VBE7
