Got an S-7 last week and seemed to work fine for a few days. Now after a bit it starts getting extreme HW errors. I can reboot and it will go again for a bit. Temps are all 53c or less, 3 plat 1200w server psus, no x's on boards. Any ideas? I've tried latest firmware and dropping from 700 to 550mh, but still getting way too many errors.
I had this problem with a couple of S7's.
They are VERY sensitive to input voltage. If your PSU is not delivering at least 11.8V under load you will experience high errors. I had a PSU that crawled down to 11.2 V after the S7 warmed up and got errors around .68%
That's high for an S7. Once I attached a better PSU errors went down to about .0126%
