Very nice on the 270's!  .955v is very good!

You must have some really good cards. Some of mine were unstable below and around 1.0, but they're all very stable at 1.100. I'll have to go another round of testing to see if I can get them stable at 1.0.

My biggest problem now is that they're running on Linux, which I haven't found a good under-volting guide for. So if I wanted to do some testing I'd have to pull them out of the rig I made and put them in a windows box to flash with ATIflash.

Great work!
