I had 2 boards fry aswell. Can you confirm your's was done by syscooling v1 harness?
I'm interested in this, if someone still has a v1 harness that fried boards, can you cut off the insulation and take me some pictures? I can only imagine that a +ve and -ve were reversed and soldered to the wrong group, else I'm stumped.

I have 2 I'm not sure which one is the firestarter. (Put them away in a box after the incidents). One had a dead pump around 6 days in (could have been from dry testing syscooling did or could be harness). Other actually killed pump and burned a fire on components of fan controller on 2 boards about a day after. My worry about cutting insulation is if something is touching doing it by cutting insulation I could lose the two parts touching. I was hoping eventually syscooling would pay compensation and want harness sent to them. But it appears syscooling did not get report of fires or burning..... I'm not sure how they are studying it without getting one of the bad V1 harness. Then again maybe like I thought they just don't care. If you can get syscooling to pay shipping I'm willing to send both dead pumps and both bad harness to you dogie.

Because the reason for the harness upgrade was bad crimp connections - not something that could damage a board or cause a fire.

Has anyone figured out the setting for best watt per GHs ratio. I thought lowering the frequency would reduce watts/GHs but it doesnt so much in my case. If I increase frequency to 250 which in my case was stock frequency, my power consumption shoots up to 950 W and output stays around 1040-1100. I am afraid to run it at that frequency because then temperatures go in 50s. So I am running it at 225 that gives me between 850-900 GHS for consistent consumption of 786+ watts and that seems pretty inefficient. Applying the new firmware from Bitmain support site also didn't make any difference. Btw, above watts (with 80plus Gold Rosewill psu) also include the cooling kit consumption but taking out 25 watts from above numbers still doesn't match the specs.

I received mine very early this morning. I'm in the NorthEast US. Indicates Friday delivery if customs doesn't get involved.

Dogie a paid employee knows something we don't? It's got nothing to do with a lack of cooling - there appeared to have been some fan cables that had wires crossed in the first generation cooling kits. Syscooling says they've completely changed the wiring.

Dogie a paid employee knows something we don't? It's got nothing to do with a lack of cooling - there appeared to have been some fan cables that had wires crossed in the first generation cooling kits. Syscooling says they've completely changed the wiring. Mine was bad enough to start fire on fan controller components.... this was in 40ish F degree ambient temperature so has nothing to do with heat. It was faulty harness. I have offered to ship it to anyone it would help. Woke up pump/fans were not working. Opened up and moved to another fan controller. With the case off and turned on visible fire came from fan components. I run without their harness. I bought a molex to fan board I'm currently using to power. I feel sure that it was harness. One pump set died around 6 days, and other a day later. They are now running with a new pump, and molex controller I bought my self. I can only tell and explain how Syscooling handled situation with me and how painful it was. I am not a harness genius that is why I would still ship it to someone who is. I am expressing my own personal opinions, and in no way are meant to be slander but to get syscooling to make the situation right. Is it possible I am wrong.... sure.... I just highly don't think I am with seeing the flames with harness plugged in and stop when it's out. I am just wanting syscooling to make my situation right. Take this and all previous or future messages about situation to be my opinion. Still willing to ship to you if you pay shipping Dogie or Syscooling. Again I do not blame Bitmain they were very helpfull. Syscooling not so much. My RMA parts are still lost in mail..... I bought new parts on my own to replace. *I'm not cutting it as I am afraid that would loose connection. Something is touching in it that should not (I am guessing). If you want shipped let me know.

Just cut the sheath off and take a picture, it would take 30 seconds. You're making a claim that should be impossible (by the mechanism you've stated), so you should really provide some information.

First board is very dead, sure its not had any coolant on it? Any visible defect? Its really rare that you get a lack of ships showing rather than XXXX chips.

Everything looks brand new, no strange smells, nothing setting off alarms to my eye that it would be defective. And not no coolant on it, also the setup was followed exactly as the instructions. Everything went fine until up to this part ![Huh](https://bitcointalk.org/Smileys/default/huh.gif)

Took off the case and moved power cables in and out. Unplugged and replugged. Changed frequency around a few times.
And now that board one is showing, ASIC # 16 but all "-------- --------"

Bitmain's support is great. If you email pictures and whats happening to info@bitmaintech.com they should help if there is anything else or if it does need to be RMA. It's looking like it's a faulty board.
