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.

Dacentec, best deals for US dedicated servers. They regularly restock $20-$25 Opterons with 8-16GB RAM & 2x1-2TB HDD's (ofc, usually lots of other good stuff to choose from).  I did a Serverbear benchmark of one of my $20/mo Opteron (June last year), it's here.  Have had about a half dozen different servers with Dacentec, & none have failed to sustain at least 40MB/s (burst higher). My favorite is a 12-month rent-to-own ZT Systems 2XL5520 16GB 2x2TB SATA for $40/month (got lucky with the 'off-brand', haven't seen a RTO 2xL5520 for under $50/mo since -- at least for monthly contracts).  wholesaleinternet.com has some ancient 2-core intel CPUs @ $10/mo sometimes (I got an Intel Core 2 6300 @ 1.86GHz, with a 250GB HDD with 46000 hours on it, LOL. $20 @ Dacentec is much better, if you can grab one). joesdatacenter.com (same location as Wholesale Internet) also occasionally has specials (or if you don't want to wait, it has an AMD Opteron 170 @ $16/mo).
