I would love to see an expanded version of this that goes down to 100 (or lower) memclock using latest version of cgminer, latest drivers, and SDK 2.1.

Here is some tests

You sir, are full of awesome. Will we be able to see the other test results soon?
Do you have a 5870 to test with?

@tenzor Were you running this on linux? And are you willing to share the script you used to generate these results?

Here is it
http://pastebin.com/gpFDyXef

requires screen

Copy it into cgminer's directory. Make sure you change values on config section. Results will appear in directory defined in "results" variable. Make sure it writable.
Cgminer always include default config, so rename it or remove. Config to run cgminer in "cgminer_config_path" var. Here is my config for device #0 (test0.conf)

Code:

{
"pools" : [
   {
   "url" : "http://pit.deepbit.net:8332",
   "user" : "XXX",
   "pass" : "XXX"
   }
],
"intensity" : "9",
"gpu-engine" : "0-930",
"gpu-fan" : "0-85",
"gpu-powertune" : "0",
"gpu-vddc" : "0.000",
"temp-cutoff" : "95",
"temp-overheat" : "85",
"temp-target" : "75",
"auto-fan" : true,
"expiry" : "120",
"gpu-threads" : "2",
"log" : "5",
"no-restart" : true,
"queue" : "1",
"retry-pause" : "5",
"scan-time" : "60",
"temp-hysteresis" : "3",
"api-listen" : true,
"donation" : "0.00",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}

sometimes X server hangs, in this case script will create file "reboot_required" in current dir, so you could use ither script to reboot automatically

First parameter is device number to run tests on. It 0 by default.

Also run another instances of cgminer befor running this script, because it will overwrite another GPU clock values.

Sometimes identical GPUs with same clocks produce different MH/s, so be careful comparing results from different GPU.

Results will appear in subfolders in json files. I wrote php script that draw graphs. http://dl.dropbox.com/u/569082/cgminer-tester.zip Put it into webserver webroot somewere, tests put in tests dir inside.

Currently I am testing 5850 all kernels 150-300 memclock. I expect results will be ready after 3 days
