Running Radeon HD7770 with Bitminer on overdrive at 1150 Mhz (clock and mem) with manual fan to 75% producing ~215 Mh/s

Just learned about BTC and so happens I have this card so I set it to work.... waiting on my BFL ASIC (like everyone else of course)

If you have further comments regarding this set up TIA

Downclock the memory to ~1000Mhz. Memory clock doesn't help mining. If you go too low, your computer may freeze.
You may be able to get the core to 1200Mhz with some voltage tweak. I wouldn't exceed 1.25v.
Check the LOAD temperature before leaving the pc mining all night.  Smiley

good luck getting a avalon in the third batch. $6000+ per asic. ones on ebay right now going for $15-30k+

i believe in bfl at this point, things are coming along even if they are slower than avalon.
