My S2 batch 2 has been hashing stably since it was delivered in April.
Today I suddenly see the hash rate fluctuate wildly, going down to 300gh then back up to 1100gh and so on.

I'll investigate when I get home. Has anyone seen this behavior?

The same happened to me this last night, dont know why Sad

. I am mining at eligius by the way

Compared to the other miners I have in my farm (Bitfury, A1's, S1's), it seems the S2 submits a disproportionate amount of duplicate shares.

Has anyone else noticed this, and aware of possible solutions ? Isolated case ?

Sorry can't find the coupon exchange topic.

7 S2 400$ coupon, valid 'till 30.05

7 S1 0.05Btc coupon, valid 'till 29.05.

Give it for free....

I won't buy hardware this month.

Drop PM if interested.

Edit:

Out of S1 coupons.

1st was xoun for 2 coupons.

2nd was klondike_bar with 5 coupons

3rd was Gogreen with 2 coupons. (He had luck, I found 2 more on my girlfriend's account.)

So overall no S1, but have 9 S2 coupon for free. Just run with it.... Grin

Pack your miners better please. Almost had a ruined miner.

Happily it is mining away at 1 Th/s after an hour. Please please please fix how you ship the S2, because cards shouldn't be sloshing about in transit.

Mine arrived way worse Tongue

.. had to RMA at least 3 board .. still waiting for new boards.

Pics please!

I received a unit today that all the cards were all over the place. 3 of the connectors were bent and a 4th was ripped off completely. Also 2 of the fan pins were mangled. I emailed bitmain and asked for a refund as the unit has no hope of being repaired.

My batch 3 S2 is plagued with problems.

1. Impossible to reboot/shutdown(Hot or cold) without having do SD recovery. (SD recovery never works first time around)
2. 1 blade intermittently gets XXX00XX ---XX--00 in ASIC status
3. 1 blade permanently gets XXX00XX ASIC Status
4. 1 blade after 2 days stops hashing and temperature shows its about 20 degrees cooler.

Asked for repeated RMA but support keeps on ignoring requests or offers troubleshooting solutions that are no longer relevant.

Pretty pitiful really, I don't how this unit could have passed their Quality Control process.

My batch 2 S2 has been hashing at around 1 TH/s since I got it a month ago.

However, in the last two days the hash rate has fallen to an average of 900 GH/s.

You would think a blade had failed, but I don't think so because sometimes it still hits 1 TH/s. The chart on the pool shows it hovering mostly around 900 GH/s.

Has anyone else had this issue?

Just to update: I SSH'd into the S2 to have a look. Couldn't see anything wrong. It had been up for a month, so I tried rebooting it. Problem solved, it is hashing at 1TH/s again.

Strange that it should slow down after a month of uptime, but I guess rebooting it once a month is pretty minimal hassle. See if it happens again in a month's time...

even my s-1's just stop once or twice a month.

That is why you cannot find easily S1 coupons for donation anymore.

S2 coupons are plenty out there.

'The right to privacy matters'

yes I have been held back for this very reason.

that and really low prices on the s-1's I just spent the end of my s-1 coupon's today…

I have 6 or 8 s-2 coupon's that i may never use.

basically bitmaintech makes very good gear.. but if you get a bad piece of gear it is always a set back. so on 200-300 usd s-1's I can live with this.

but on a 2k piece of gear no.

The above is the reason why I'm hesitant to pull the trigger on a S2 either direct or through Juan's groupbuy...
