A4 Dominator - Pre-Order Group Buy - 280mh, roughly 1000w, $1800 + shipping

For dealing with some multi-pools, we found that some pools cannot deal with our miners very well for the large hash rate - > hash rate always drops to around 240Msh rather than 275 or more.

Sorry but this is nonsense.  I have multiple 5 cube Titan rigs hashing away at 400MH easily at Prohashing, Nicehash and Clevermining without issue. This has nothing to do with "large hash rate" but rather bad design and manufacturing decisions.

Rather than blame the pool operators, Innosilicon should be reaching out to the major pool operators and work directly with them on behalf of the customers who are suffering.

My ISP will be doing the B3 firmware upgrade today to v2.02.

Keeping fingers crossed that this version will fix the restarts.

Will test them on Prohashing and Nicehash - these 2 pools are usually brutal in coin/profit switching so I know it will be a baptism of fire to test the new firmware.

Its past midnight my time but I have discussed with the team in my ISP on the upgrade path.

Hopefully good news in the next few hours.

Agreed. Once upon a time the A2 110MHs was also a "large" scrypt miner, tweaking the diff levels got it to mine easily. Some mod versions can even OC beyond specs with ease. With A4s faster chips, not able to handle large hash is not justified, rather firmware and code design are likely culprit - no pool ops can help you if board drops or restarts happens randomly. Its like buying a new windows PC and randomly reboots or gives blue screen -- 99% will point to faulty hardware etc.... until you reseat that RAM or take out that rouge GPU and installing the latest drivers.... sounds familiar?

Please let us know what comes of it, I am ready to wire them some money, but not if the profit switching doesn't work.

Nice. I've got B2 with them as well so hopefully you get some good news going forward and then I can get mine sorted out. 

Here is a mining pool that we recommend to you: hashtocoins

hashtocoins is a pool I thought about using but I don't really have the time to trade out of each coin daily unfortunately.

I just upgraded to V2.02. Although it has not run long until now, the results do not look good, I think:




After about 15 Minutes of mining at pool:


Edit:
Seems it does work now, first it took some more minutes and now, even after restart it gets around ~275MH/s:


I would like to test mining on nicehash, but it seems I set wrong pool data. Can someone help me out?
What I tried:
Pool: stratum+tcp://scrypt.eu.nicehash.com:3333#xnsub (also tried without #xnsub)
Login: BTC Address
Pass: x

Doing so the pool is not even listed in the pool section :-(

Edit2:
Got it now, Nicehash is also working. It seems I did not "save" correctly after deleting the #xnsub. I double checked this now and after deleting that part it worked.

Just updated to v2.02 Beta (from v2.01 / for Batch 3 only)

** Batch 1 and 2 A4s need the MCU firmware updates **


Current setup 420MH + 420MH +420MH +280MH

From cgminer:

Controller 1 - 420MH (5s):412.3M A:13967360 R:106496 WU:290230.8/m
Controller 2 - 420MH (5s):412.4M A:21749760 R:40960 WU:368271.5/m
Controller 3 - 420MH (5s):412.1M A:610304 R:28672 WU:365610.1/m
Controller 4 - 280MH (5s):275.2M A:3678208 R:12288 WU:227760.6/m

From Poolside / Prohashing.com

(after 15 mins)




(after 30 some minutes)




Ran one of the bigger miner to Nicehash and after 10 minutes




Do we have a winner here?

Will let it run for while more to see if any drops or restarts.

Anybody knows what is the recommended password string for Prohashing?

I recall Steve@Prohashing mentioning h=50 and g=off, do we still need that?

Also on another note.... those who are near your A4s... please check closely the quality of the fans... overheating maybe result of "used" fans... please check to verify.

Hi Guys,

I have my A4 miner now for a several days. Batch 3 running V2.0.2 Beta.

I am mining @Prohashing and it drop's several times a day. I added a rule that sends ma a notify when it comes below 200 Mh/s.

 Total hashrate      190.885 MH/s   53 minutes ago 
 Total hashrate      167.024 MH/s   09:05:20 
 Total hashrate      133.619 MH/s   08:35:01 
 Total hashrate      181.340 MH/s   07:35:26 
 Total hashrate      124.075 MH/s   05:00:01

I tried different settings (low speed, higher speed and difficulty). With all settings it drops.

Does anyone knows what more i can do?

drops a board? or restarts?

monitor the temps on the board that is dropping...

suspect that overheating maybe the culprit - please check your fans closely - you may want to replace them if so.

[trins123]

Has anyone installed the firmware update yet?  Any updates or reports with the new firmware? 

Has the firmware been posted somewhere? I'm happy to test it out.

Hi,

I can confirm that 2.0.2 firmware on batch 3 miners is mining a single coin for a few days without a problem.

But I still havent tested it on multipools enough.

Regards

[collectiveseven]

For now, i changed the diff back to 8192..

2hr avg hashrate: 286.60 MH/s

Running stable for 3 hours now! (@Prohashing)

I post an update here, after a few days!

@citronick how many watts are you pulling at 400+ mh/s?  If we can stretch the legs on these like that without dramatically increasing the power draw and sorting out the restart issue it will be a happy New Year for us!

I don't believe he is running a "normal" 2 cube setup to get those numbers.

820mV

69.5MH /1200Mhz per blade x 6 blades per controller

My A4s are hosted in Canada so let me know what info you need so I can get them from the ISP. Anything frontend I can do myself remotely. But if you need to do any backend kill-o-watt measurement I need the guys to help.

yes you are right.

I ordered 6 x A4 280MH

but I am missing 1 cube and 1 controller because DHL has not sent the last box to my ISP.

So after tearing my hair the whole of last week, got the cubes into 6 blades per controller so that I can run it in a solo pool.

the 417-420MH per controller format seems to work fine in multicoin pool too and I can use diff 32768 with the large hash so I guess I will stick to this format until my last cube & controller arrives.

Ah okay. I have 6 with the same ISP I believe so I will check with them on my settings and see if any improvement can be made based on your results.  I am not even 100% sure if my miners were B1 or B2 bc I shipped them straight to Canada.

They almost have to be B2 because they have been "decent" for 2 weeks on nicehash as far as the hashrate not slowly creeping down.

[cisA]

I love the A4 issue :-)

[FryguyUK]

if you're having issues with dropping, consider:

your ambient room temperature wants to be around 28 degrees or less - Lots of cooling required

PSUs must be plugged into individual sockets or specialized extension cables - 2 miners into one normal 4 plug extension etc that is a no daqqa

hi everyone, i want to share my experience with the miner software version, the V2.0.2 did great job. 5 X a4 running for now 6 day without any trouble, no pool disconnect and very stable
thanks you to inno for the support and the very good service, i recommand it to everyone, look like all problem is solve with this new version

Are you using a switching pool, or mining a single coin?

Cheers.
