Waiting on the EVGA 1080 TI (maybe the Classified Edition) to get a Paschal card.

Now that we can fully utilize the GPU under Linux with SWAN_SYNC=1, I can compare the performance of my cards for real.

Impressive.
What is the power draw (reported by nvidia-smi) and GPU/Mem clocks used to achieve these stats?

I just typed in "nvidia-smi" into the terminal and it gave me a basic overview, I have a watercooled evga hybrid 1080ti and it is reporting with SWAN_SYNC enabled:

224 watts
53C
655 MB/ 11171MB RAM usage
99% utilization
2% BUS interface load

I too get around 1.5 million RAC when it is sufficiently supplied with WUs.

I have another system with two evga hybrid 1080tis and I get:

243 watts
53C
868 MB/ 11171MB RAM usage
99% utilization
2% BUS interface load

213 watts
45C
678 MB/ 11171MB RAM usage
99% utilization
2% BUS interface load

This basic overview is unfortunately not detailed enough to show clocks but in "Nvidia X Server Settings" I find that all GPUs are running at 1949Mhz clock and 10010Mhz Memory.

Thanks for the stats. A more detailed view is available using "nvidia-smi -a"
nvidia-smi also works in Windows (execute in c:\program files\nvidia corporation\nvsmi folder at a prompt)

In Linux -
"nvidia-smi --help" will give a lot more options
"nvidia-settings" is also another handy commandline utility. Good tool for scripting although the graphic version (nvidia x server settings) is easier to use.

The power options you provided is of great interest as I always try to produce the best output for the least possible power.

Linux with SWAN_SYNC enabled is the highest performing out of any OS. With SWAN_SYNC enabled you can achieve a true 100% usage on seemingly any CPU/GPU combination. I have noticed that the BUS interface load has significantly decreased with SWAN_SYNC enabled, most likely allowing this true 100% utilization.

How do I prove I have SWAN_SYNC enabled???

Some of your computers have it enables, others don't.

Look at the stderr reports of the work units of the different computers using Linux. Unfortunately in Windows, can't tell if it's running or not.

How do I prove I have SWAN_SYNC enabled???

/lib/systemd/system/boinc-client.service
First line under Service: Environment="SWAN_SYNC=1"
Reboot: printenv

And SWAN_SYNC is not shown.
