LARRY didn't want to run for more then 2 secs... so i lowered the clocks settings down to 300 (--hfa-hash-clock 300) and LARRY decided to hash for more the 10mins. After which I kept upping the MHz by 50 every 10 mins, all the way to 604 (--hfa-hash-clock 604).
Hey,
I have 2 hfa devices that have been running in a colo for months without any problems.
Running cgminer 4.8 these days now
One system decided to throw in the towel last week with the same error, overheating.
If one starts up cgminer the first time it states:
HFS hfsb: Hit overheat temp 96.1, throttling!
HFS hfsb: Thermal overload tripped! Shutting down device
(the following times you launch cgminer it just mentions
HFS hfsb: Thermal overload tripped! Shutting down device
and no additional info. Only if you power it down for a while it cools down enough)
I only managed to keep it running if I set the freq to 125, where the temp is hovering around 98 degrees and it complains all the time
HFS hfsb: Hit overheat temp 95.3, throttling!
or similar temperatures above 95 degrees
I guess I have a cooling issue (bad heatsink, all three fans are running at --hfa-fan 100 and do pass a load of air, or a bad temperature sensor).
How does one isolate the problem to one of the three boards?
Do I have to hook up each board separately like in the BabyJet?
Or could this error be the symptom of having a bad power supply (I guess that is the next suspect on my list)?
