Antminer S9 one hashboard stop appearing in STATUS

[Minestrone]

If you want to fix it you probably have to pull the FETs on the board, at least the high side ones. This will require hot air tools, good flux, and a good pre-heater. I have all of these, if you want me to look at it drop me a PM and I'll send you my address.

As Bitmain are not going to respond until the 25th I pulled the board anyway. There`s no obvious problems on visual inspection. Which FETs do you you mean by "the high side ones"? There seem to be four on the back of the board two marked 6040 an two marked 8040.

The high side MOSFET are the two Square chips closest to the power connector. The 6040 and 8040 are drivers because I believe that buck controller is only designed to drive one MOSFET(per side).

Usually you would drive a high side and two low sides. The problem isn't providing gate current, it's the speed at which a normal gate switches. On a normal buck inverter most times the ground is on, with short excursions of the high side being on. Thus low side should have two FETs to ground the power line, and the high side needs just one to do the quick transition. If you put two FETs on the high side you need more gate power *and* the gates will switch more slowly due to capacitance.

On the S9 it's a bit more interesting, the voltage is closer to the median than the S7, so they felt the need for dual FETs on both sides. Which needs more gate current.

Fun stuff.

Surprisingly Bitmain responded quickly but unsurprisingly asked me to return the whole unit. They did offer to give me one of their coupons to cover the shipping costs. So basically they`ve sold me something that stopped working properly after only one day, well within the warranty period and expect me to pay shipping and repay import duties if it is returned to me, and it will only be returned if they deem it DOA. But I will get a coupon (value unspecified) to help buy another unit from them. What a joke!

Ya, that and the fact that they switched to a new buck controller that cannot be purchased easily, ON semi however makes almost identical parts(hell they probably copied ONsemi, lol). I have absolutely no idea what the 8040 or 6040 transistor specs are(no datasheets exist as far as I can find), might have to get the converter and MOSFET data and do the math. Wish BITMAIN would release the '87 datasheet already too.

Hi

Sometime my S9 have same proplem. I unplug power cable, unplug all 6 pin 12 Vdc connect from power supply to machine. Wait 5 minute and plug all back. This is solve my problem.

I think that this problem occur when temp hash board to high and HW asic component error so  machine try to reboot, or there are sync sock of power supply.

You're a gent, this seems to have fixed my problem. Previously I flashed firmware and reset, which always got the board hashing for 1 - 2 hours, but I tried everything you stated and it's been 4+ hours and it's OK.

I do wonder whether it's the PSU....

[arominer]

Unfortunately it didn't work. I have just switched pools however, so I am going to see if this may work....

Again each time I reboot it restores hashing

So it runs for a bit then crashes? May be a bad chip that is showing signs of thermal expansion. Want to send it over and I'll look at it in IR?
