pilotchup,

Golden 280X's? Or lazy 290's? Grin

If they're 290's, I gather you've got them tuned for efficiency/lower temps instead of all-out hashrate?

Sorry I didn't leave a comment with the picture. Posted it right as we were leaving the house.

They are indeed 290's. Just got them operational and was having a problem where GPU2 would report SICK/DEAD after 10 minutes of mining so I took the settings way down to see if that was the culprit. So yes, they are lazy 290's! Looking forward to tune them soon.

These are water cooled as well, it isn't that high performance of a water cooled system (since I didn't want to spend a ton of money in that), which is why the temps are in the 60s.

Therefore, that RPM you see is not fan RPM but my two pumps' RPM. I made a custom cable to connect the tach of my pumps to the sensor on the GPU that is for the fan. Then I wrote a program using cgminer API to auto-shutdown the computer if that RPM falls out of acceptable limits (aka pump failure).

Going to write a guide soon on how to get 6 R9 290s working, since I had a helluva time getting it to work. There really isn't much info out there on how to get that many working.

Cheers!

p.s. that is fastcoin solo mining, was just experimenting to see how solo mining works.
