Since i"m new (don't have the requisite numbers) to post to the appropriate section, i'll have to post this here.

I've been a casual windows bitcoin miner since last june, mostly using guiminer and Poclbm, but this is my first 7000 series card.

So far I've only been able to get the MSI 7770 to about 1075 getting 196Mhash with -v -w128 -f10.

But I can't find a program that will underclock my memory. This 7770 is using a ton of wattage at 925mhz memory (lowest I can get it in catalyst), about 88W. Anyone have a way to downclock? I've tried afterburner, barelyclocked and sapphire trixx.

Info:

Windows 7
12.6 drivers
amd 12.7 sdk

Also, if theres a better miner for the 7770 let me know, I'd be glad to try it.
