Bitmain Antminer A3 earning $500 a day mining SIAcoin . .WHAT?! Results & Stats

[tummymumma]

People are buying these for over $5k on eBay  What are your thoughts on that?

Well, if you look at some of the ads for the A3s, they st ill say 16k per month which is silly, but I think the prices will drop a little but I dont think your going to see them come down to under 4500.. The s9's are still selling at that level.  As long as they are earning a decent amount.....

I do 98 $ per day since today... my ROI in 25 days... 2800 $ per month... That's good for me... And if the Siacoin increase in value... this is the jackpot...

I'm in it for the long haul on the A3, and don't like the temps getting above 80 degrees. Has anybody had any luck underclocking these to a decent level? I cant seem to keep the temp below 80 despite max fan speed.

In a nice cold garage btw.

i think the A3 will end the same way as the D3

yes but when you look at the price of dash, it hopefully will follow the same trend.

the L3 people who bought batches for march are getting screwing because now bitmain magically decided to ship *another batch within 10 days

couple weeks ago I finished building farm of D3s for one customer of mine, 50+ D3s and I even remember his call back in September asking me what to buy D3 or S9, even tho I was insisting on S9 and they were 1415$ then he bought bunch of D3s
in conclusion I can say that they are checking only purchase date profitability and don't look forward
it's bad people are so greedy even tho you are trying to help them but who cares in the end everyone gets what he deserves

i think the A3 will end the same way as the D3

imo they will last longer than D3 did due to lower quantity

the PCB or chip temps ? mine are now all occed to 650mhs @ 900ghs and i see PCB temps below for one

Code:

Temp(PCB)	Temp(Chip)	ASIC status
1	60	650	312.48	10,470	58	77	oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooo
2	60	650	298.47	6,640	57	77	oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooo
3	60	650	313.25	28,900	60	80

the other is a bit more flakey

temps are around 75- 86 do i downclocked to 630 ish for same temps 880 ghs

FRIED HASHBOARD!!!

FRIED HASHBOARD!!!

how ?

[LazyJones]

over 10000 errors does not give me confidence to overclock my boards, I like running them for longer than a week.

the bulk of the HW errors happen when the unit first joins the pool, then after an hour or too they stop

I do agree though , what is needed is a way to change the voltages and frequencies of boards individually, some  boards are fine with as high as 680 mhz

where others struggle at as low as 550

I think the bulk of these have been arriving yesterday and today.  My guess is that they should settle around $50 per day mining over the next 2 days.  Still not too bad.  So far the estimates seem to be somewhere between 11,000 - 14,000 units sold.  Will be curious to see where the actual hashrate ends up.  My guess is that this is going to increase the price of Sia as it is bringing a lot of new people in to Sia's realm who otherwise might not have looked at it.  I think Bitmain did a better job with realeasing the A3 than they did with the D3.  Less supply, and limiting to 1 per order.  That should hopefully have allowed the A3 to be distributed among more people, hopefully.

I do agree that these run way too hot and too loud (mine was mid to high 70's even with cool temps here in the garage but was hashing about 832 GH/s).  Good luck keeping these cool in the summer.  I think they would have been better off reducing the number of chips a bit and make this a 600 - 650 GH/s miner and people would have paid the same price for a machine that would run cooler and draw less power.

I was using Antpool for Mining Siacoin with my new Antminer A3 machine. The machine connected at 8 pm yesterday UK time and now its 8 am uk time.

The machine is hashing. But no revenue.

Please see the attached pool network hash power too. Lot of people started mining and moved. Also the total block solved is shown as 0.

Is Antpool failed against Siacoin?

Anybody have a similar experience with antpool?

Antpool is PPLNS, you won't have any revenue until it finds a share. If you want a PPS pool try siamining

Have spent quite a bit of time with mine, I've gone through the whole unit software / hardware wise and made quite a few hardware notes that ill curate and share at a later date.

Voltage control is whack on these, needs custom firmware. Over the past few days of testing i was getting the following.

600mhz, 80C, 10K+ HW errors
581mhz, 55C, 5 HW errors
575mhz, 70C, 7K+ HW errors

How reducing clock speed results in more heat + HW errors is beyond me unless there are serious voltage calculation issues with these things. Also the CPU on the control board is running near full tilt just to keep up with the UART activity on the hashing boards. So even the simple act of refreshing the web page can give you HW errors. These aren't real errors, but just the control board lagging behind.

Also these are identical to the D3 in almost every way. pic firmware, eeprom images, etc... are all identical. The only thing that sets this apart from a D3 is the ASIC's, but considering it has all the same issues that the D3 had it makes me wonder if bitmain has come up with a more universal ASIC chip that can be reconfigured. There are JTAG headers on the hash boards, so who knows?

We'd like to offer a $800 @BITMAINtech discount coupon to every @ObeliskTechHQ coupon holder. We look forward to collaborating with the @ObeliskTechHQ team to finalize the details. Stay tuned for more information on this.

Great review, thanks man

[The Demon Slick]

I can extrapolate the yield drop from my 2 580s rig.
before hard fork at block 139,000  1 sia per hour
right after  .5 sia per hour
now .2 sia per hour

Yield has dropped by 80% since the fork.

I underclocked to 525, set fan % to 85, or 5,210 rpm give or take.  That keeps my chips at 71-74.

With a cold garage, I would think you might get by with 550 and a fan speed over 5,000+.
