Well I have a good chunk of sample data at https://docs.google.com/spreadsheet/ccc?key=0AjXdY6gpvmJ4dEo4OXhwdTlyeS1Vc1hDWV94akJHZFE&hl=en_US#gid=0
but it's currently for 2.1 SDK. Would need to uninstall 2.6 and install 2.4 sdk instead (which is fine for me, dont use 2.6 anyways) and run all the combos the same way. Here's a pretty graph in case you don't want to read the spreadsheet.
Note: My sample is very incomplete. It requires a lot of time to test all the combos. Environment was Win7 x64, phoenix 2.0 RC1, phatk 2.2 kernel, 12.1 driver, 2.1 SDK, AGGRESSION=14 BFI_INT with varying worksize and vectors. Card used is an Asus Radeon 5870 @ 1035mhz core.
Hey, thanks for that. I've been running my 5870 @ 1000/300, vectors w/ worksize 256.... Now at 1000/210, vectors, worksize 128 and basically same hash rate. Lower temps, less wattage... cheer.
