Hi guys,

latest sph-sgminer head from github has an issue with auto-fan. When option is present in command line, the miner hangs together with the entire system. only a reboot recovers the machine. however enabling auto fan per gpu while miner is running works.

cgminer 3.7.2 compiled from source works perfectly on the same machine

tested on:

OS: Centos 6.5 final x86_32
AMD SDK : 2.7
AMD Driver : Catalyst 13.25.5
AMD ADL : 6.0
TestRig 2x Radeon cards 0 7950 GB FT0(bios mod) 1 7770 STOCK

cheers,
JD

the component marked FB is a ferrite bead(5 on your marking). the rest are capacitors.

my 2c. if possible use a physical storage device like a SAM module or in case of servers an HSM. storing in ram makes them vulnerable. Keyloggers and ramscrapers are just the tip of the iceberg.
