Hi all, I have a problem with an HEX8A1 board. I have two HEX8A1 boards. I have change the fans since it was way too noisy, and i use a 220/920 setting. The two boards are linked to a TPlink router with openwrt ("OpenWrt Barrier Breaker r40295", i think it is a 0.3.0) through an USB hub. All (tplink and boards, hub is not externally powered) are powered with the same Corsair CX760. This was working like a charm for the last 6 months. But since two days now, one of the board is not hashing anymore. Everything looks fine, the board is seen by cgminer, when i plug/unplug it i can see the board disappearing/reappearing, but the hashrate is always 0. The second board is working and hashing. The led are the same on the two boards. I have tried to plug only one board, i have tried 210/860, i have change the usb port, i have plug the faultly board directly to the TPlink, i have reset settings to 260/1000, but nothing worked. I don't think it is a overheat problem, cause the fans are identicall on the two boards, and with those fans and settings the boards seems cooler than with the noisy sunon and 260/1000 settings (i can put my finger on the it for more than 10s  ). Moreover, i have a very very low error rate, and i did not change anything on the configuration for the last 6 months (and the room is at 18°). Any idea ? How can i see if it is a overheat problem ? Seem like hardware problem. Try to let the board cool down for few hours, check if there is any hardware burn mark. Then try again. Then please post cgminer api log. I have unplug the board last night, and replug it this morning, without any result. The board is not hot at all. There is absolutely no burn mark on the board. Here is the CGMiner API log (a few minutes after a restart of tplink) (for information, error rate is 0 because of tplink reboot; after many hours i have never seen error rate over 0.1%, most of the times it is between 0.01 and 0.08) : [Firmware Version] => 20140328

) [/code] What is strange to me is the PICVoltage that is always 800 for the faulty board (i can see this with putty and cgminer output too ...). This let me think of a power problem, this is why i have tried with only the faulty board, without any success. |
