Bitmain just announced the AntMiner A3 - 815GH/s Siacoin miner - Blake(2b)

[btc2017btc2017]

just got mine hooked up

PCB temps 57, 57, 61

Chip temps 77, 79, 84

running at 525 AVG 729 gh/s

52   69   
50   66   
56   78

569mhz - 787ghs

I turned town the frequency because I've lost 1 S9 board before and 1 avalon board

so with your temps I would get some kind of better air conditioning or venting

It is better to extract to exhaust air to the outside, it is much cheaper than aircon. I use 6" ducting

yea thats what I mean by 'venting' looks good

I turned down the frequency because I've lost 1 S9 board before and 1 avalon board

so with your temps I would get some kind of better air conditioning or venting

temps have normalized after letting run for a bit to this

pcb - 57, 58, 63

chip - 68, 70, 77

FANS ARE SUPER LOUD

Fan 1 - 5,910 Fan 2 - 5,190

anyone know of a simple sound proof setup that doesn't require venting air outside?

I don't know, They're so loud I can hear it on the second floor from the basement. It's intolerable.

the fans are forced to run at damn near max because of how hot it gets...i suppose baitmain wont be addressing this anytime soon..might be best just to mine for a week then sell

Saw a video on youtube where a guy plexi-glassed the miner on both sides and it totally made it tolerable.

Seems A3 had changed the ventilation fan model when compare to L3 & S9.
I run both S9 & A3 in same room, the A3 fan have higher running speed but still keeps higher chip temperature than S9.
Also I can heard some fan knocking sound from A3 intermittently

What are your HW errors and chip temps when overclocking your A3?

[BenRickert]

Based upon what I've been reading across multiple threads, if you own one of these, I would definitely underclock it unless you got some amazing cooling in front of it

Under clock by how much?? Any ideas? I am about to leave town and don't want this thing blowing up. Anyone have a good setting to put it on?

On default setting (600) it seems to be overclocking. I'm averaging over the stated 815, but also getting a lot of HW errors and chip temps seem high especially since L3+ says keep under 80 C. Any suggested settings would be helpful.

Yup, just like the D3's. They knew these units were going to have a limited shelf life. They're definitely overclocked. You can tell by the numbers that they are running at redline. I would strongly recommend against overclocking these. Not only for the miner's sake. They're drawing a LOT of watts and amps. If your breakers and wiring aren't extremely robust, you could be playing with fire. Literally. Especially all these folks in here talking about running these beasts on 120v. Bad bad idea.

I feel bad for the Obelisk buyers, they're really screwed unless SC price goes through the roof.  ROI is drastically decreasing as more miners come online.  ROI is now $75/day.

Care to explain about why running on 120v is a bad idea?

I am running on 120 V but not with just 1 PSU. Instead I am using 2 PSUs - one APW3 (to power 2 boards and main) and one EVGA 750 BQ (to power third board). Power cables are 14 AWG and extension cord is 12 AWG. I am also using a surge protector. EVGA is pulling 465 watts. APW3 is pulling 940 W. Making it 1405 W total. Which is still under 80% of max (120 V x 15 A = 1800 W). I am making sure that nothing else is running continuously on that breaker (once in a while a LED lamp or a iPhone charger).

Frequency set at default but manually set fan to 100%. PCB temperature varies from 55-65 and Chip temperature varies from 70-80. Mining at 815 GHS.

here my data

Speed. 840.88 GHs
Temp(PCB): 74 74 79
Temp(Chip): 88 89 96
Fan Speed: 3,570
Customize the fan speed percentage is aktivated ro 55%
Noise is very good, is rather quiet

14000 SIA sinze the miner is running

And, i will hold all the coins over the next 1-2 years and sia will rise up to XXXX :-)

for me would be ok if just double

[SWA_HD]

Have theory that A3 was build on D3  and this is the reason some A3 (including mine) have problems with hash boards - appears/disappears, hashing/no hashing, all asics few only and then turning 0000 into xxxx...

Nothing is helping to solve: rebooting, restarting, resetting, plugging / unplugging, each by one, separately, adding two AWP++ , changing controller cables 1/4, 2/4, 3/4, 4/4  Even flashing ( thank you blissz) - NOTHING

But funny my D3 with A3 firmware turns into A3 miner, even connects to the SIA pool, but not hashing and after moment all asics turns xxxx

This suggest than  sia network or "brick attack" on 24th is not the real problem. The real is that bitmain cleaned D3 stock transforming them into A3 thought

____  NOW the funny moment. If/when somebody finds out hot to avoid that wall  to make D3 (with A3 firmware) hashing on SIA network.... Smiley  ....... ALL D3 would finally be able to deliver ROI

lol double ? you cant be serious, Its crazy to sell any sia until it hits at least a $1 at this point
the hashrate is about go go parabolic, it soon will be like dash when the obelisk Asics launch
-unminable by gpu and even 800 gh nets like 100 sia or less a day

im dead serious:
1. Sia is not Dash (Dash is hyped and heavily supported top-10 coin)
2. To get to 1$ Sia needs a miracle, but now all i see is spontaneous and emotional statements by their management - not good for coin price (even though they decided not to fork Sia - seed is sowed)
3. Obelisk production is now under big question - same hashrate as A3 in March or later make no sense at all (i'd quickly re-arrange algos/techs or return money to customers)
4. Hashrate will not go parabolic - it will grow upon new A3 connection to pools

double for a price target smells of FUD to me , heck it was tripple what it was back in dec when all alts pumped and your price target is a double ?! gimme a break lol , that basically invalidates every one of your other points , its mostly pros here bruh , not knee jerking newbies we know bs when we see it 😂
