low c/s and no fan speed
#1
I've recently put together a new PC that uses a 5970 and two 5870s (4 GPUs total, crossfire bridges are not being used). This PC uses Ubuntu 12.04LTS and AMD v12.8 drivers that were installed per these directions. The only deviation I had from those instructions was issuing the command "sudo aticonfig -f --adapter=all --initial" so that all four GPUs would initialize.

Here is an output of lspci:

I was excited to see the capabilities/horsepower of my new PC, so I executed an md5 benchmark in hashcat-lite v0.10.

Here is the output of that benchmark:
Code:
sudo ./oclHashcat-lite64.bin -b --benchmark-mode=1 -n 160 --gpu-loops=1000 -m 0
oclHashcat-lite v0.10 by atom starting...

Wow! I was very happy with my bechmark results considering the budget for it was relatively low. I thought it was odd that the detected memory was half of what the GPUs have, but it didn't bother me too much.

To get an idea of oclHashcat-plus64 performance, I issued a simply 6 keyspace brute force attack against the example0.hash list that comes in the zip file package.

Here are the results:
Code:
sudo ./oclHashcat-plus64.bin -a 3 -i -n 160 --gpu-loops=1000 example0.hash ?a?a?a?a?a?a

There are three issues seen:
  1. WARN: ADL_Overdrive5_FanSpeedInfo_Get(): -1
  2. low c/s compared to lite's benchmark (8961.1M c/s Real, 9209.2M c/s GPU)
  3. the two 5870s are only at 725mhz (I presume this is because of my 5970 though, so it's probably not a problem, just a configuration)

I overcame the fan issue by manually setting my fans to 100%. The command I used for that was sudo aticonfig --pplib-cmd "set fanspeed all 100". While this method works, it would be nice if I did not have to manually set this everytime. Has anyone else experienced this issue before? I tried searching the forums, but did not find anything.

The low c/s is very disappointing. Why would the benchmark in lite be so much higher? For grins and giggles, I purged my fglrx/12.8 installations and installed 12.10. Doing this was even worse because only GPU.#1 would work, so I rolled back to 12.8.

I love my new set up, but it seems the numbers are not where they should be. Sad

Does anyone have troubleshooting suggestions? I've tried my best to investigate and troubleshoot on my own, but I'm completely stumped.

Thanks in advance for any assistance!

edit-- possible "DOH!" on my part.... could the reason be because this is 'technically' a mixed GPU set up?
