Something interesting happened though, I'm not exactly sure what but I think cgminer might have overridden my clock values from CCC. I saw this and just had to take a screenshot though Grin

This was the crash I had driving home from work. Makes a little more sense now, kinda...

CGMiner has excellent OC controls. I'm no GUIMiner expert but maybe it's modifying your GPU's engine/memory while GUIMiner tries to do it's own thing? I don't mine with GUIMiner but AFAIK, it was built on CGMiner, which has it's own (excellent) OC controls. I know that some settings in CGMiner (GUIMiner?), when not set properly, can give higher-than-actual hash rates. Don't quote me but I think they're the "intensity" and "thread concurrency" settings. I'd be surprised if GUIMiner didn't have these settings built in.

If you want help setting up CGMiner, just download the compiled EXE from ckolivas (source code is on Github if you want to compile, otherwise, he hosts the latest version of CGMiner here: http://ck.kolivas.org/apps/cgminer/)

Since we have the same video cards, you can probably just use my CGMiner config settings (took me ALOT of lurking to figure them out). Copy and past the following into CGMiner's "cgminer.conf" file:

"pools" : [
   {
      "url" : "stratum+tcp://poolname.com:port",
      "user" : "username",
      "pass" : "password"
   },
   {
      "url" : "stratum+tcp://poolname.com:port",
      "user" : "username",
      "pass" : "password"
   },
   {
      "url" : "http://poolname.com:port",
      "user" : "username",
      "pass" : "password"
   }
],
"intensity" : "13,13",
"vectors" : "1,1",
"worksize" : "256,256",
"lookup-gap" : "2,2",
"thread-concurrency" : "22400,22400",

"gpu-memclock" : "0-1600,1625",
"gpu-powertune" : "20,20",
"temp-cutoff" : "84,84",
"temp-overheat" : "80,80",
"temp-target" : "75,75",
"api-port" : "4028",
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "1",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"queue" : "1",
"scan-time" : "60",
"temp-hysteresis" : "3",
"shares" : "0",
"kernel-path" : "/usr/local/bin"
}

You can't make intensity go above 13 on our cards.

You'll also want to create a .bat (batch, "bash") file with these contents:

Quote

setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
color F2
cgminer

Once you create that batch file, put it in the cgminer folder and run it from there. I didn't even install the OC utility on my rig, just installed the OS, GPU driver (AMD 12.8 with APP SDK 2.8 included, you need APP SDK), DirectX (may not be necessary), and CGMiner.
And Cablesaurus' lead time is ~7 days right? That's what I thought I read when I ordered. I'd be PO'd if I have to wait longer, not that I have the extra GPU's to plug into PCI 1x yet Cry
