When my shipment of Klondikes came, I ran out to the nearest discount store and grabbed a handful of iHome 4-port hubs for five bucks each. It'd be nicer to have fewer hubs, but they are doing the job all the same. FWIW, some of them are connected to USB3 ports on the host PC.
I recompiled cgminer 3.7.2 with line ~63 changed to:
#define KLN_KILLWORK_TEMP 61.5
and now my miners are no longer getting temperature-throttled by cgminer, been running rock solid all day at 350 MHz. My temps are hovering in the low-to-mid 50s, so the recompile was necessary for me. Might experiment with further OC'ing in the near future.
I also modified line ~1023 to:
applog(LOG_INFO, "%s%i:%d went idle before work was sent",
I was not infrequently seeing that message from cgminer. It seems important but I noticed my effective hashrate hasn't been negatively impacted. It was coming often enough to really muck up my logfile, so I disabled it by giving it LOG_INFO priority, instead of LOG_WARNING. Anyone else seeing a lot of this message?
Guys, you can significantly reduce the "went idle" states by modifying two defines in cgm driver. I've talked about that in K16 thread, but if anyone missed it there, check
