So, I do have some problems with my klondikes...  Sometimes one or two will freeze up and go to 0.0000 hashrate.

I have two K-16's that sometimes freeze up, and then upon restart, will not work, until they have been placed outside in the freezing cold for a while until they get very cold.  Then they will run fine for a day or two, then freeze up.

Also, I have 2 K-16's that will just simply just throw a bunch of hardware errors, no matter what I do. I'm going to check voltages soon.

Did you try with different version of cgminer? I was able to use them only with 3.7.2. Other versions didnt work. And yeah, check cables too. Smiley

Also,cooling the backside is mandatory for lower temps  Wink  Setup like this brought the temps down to 44-50C.With no backside cooling-as high as 63C  Shocked
