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

[kurbeks]

Should have bought some used one few weeks back. When scrypt profitability was in trash. Could have made good deals on A4 and Titans.

[lightfoot]

I'm still repairing Titans, funny how these things keep being profitable....

[Inno_ASIC]

Yep have same question. Any improvment other than Nicehash?

Yes, version 2.0.3 is only patch for nicehash.

[Inno_ASIC]

Does thkis update allow other pools to be mined efficiently or is this patch only for nicehash?

Yes.

A4s at NH

stratum+tcp://scrypt.usa.nicehash.com:3333
With v2.0.3, 6 x A4, d=65536
Current rate (at time of post) = 0.0750 BTC/per day or
.. USD$81.20 per day using 1 BTC exchange of USD$1081.99

Observations & Opinions:

1. The A4s can stay connected much longer than before at NH. This maybe due to xnsub working and now performs better submits to NH stratum server.

2. Speed at miner side shows 280MHs. At poolside, NH can push it higher. This is big improvement compared to before v2.0.3 firmware.

3. I hope Innosilicon learnt their lesson that you need aggressive testing before launching a product.

4. I hope Innosilicon also realise that this thread alone has help them detail out many shortcomings, recommendations, damage control, etc of the A4 launch. There are many miners here that have been your previous customers since the A2. So Inno should make full use of the loyal and experts in the A2 user base for new product release or version.

Looking good. Except one with 234 Mhas/s rate

[wheelz1200]

These do look like they shaped up a bit since launch glad to see things got sorted on this one.  Still figuring on what miners to get and now i might have to consider these as a viable option.

[citronick]

For those who PMed me about the A4 settings, voltages etc. See this. You can also try a lower difficulty.

Why not run it at 1248MHz?

No intention to OC this guy just yet....

I have mine running at 1200MHZ, what kind of temp you getting? My boards are anywhere from 48C to 62C on the hottest board

At $81.20 for your hash rate you're making about 5.2 Cents per MH from my calculations. Have you tried prohash and seen any better results?

Yep have same question. Any improvment other than Nicehash?

Yes, version 2.0.3 is only patch for nicehash.

I haven't had a chance to get my remote site yet to change out the SD Card.

Does 2.0.3 address any other issues? I was really hoping that it would help the reboot loop issues from Get Failures.

[citronick]

@eyedol-x, temps are fine at that mhz, but then again my A4s are hosted at Cryptoboreas, Canada and its freezing over there. Overall, I think the A4s with new firmware finally rids of the reboot issues and stays online longer at NH (Get Failures=2). I reckon it will have similar improvements in other pools.

I have tried Prohashing, zpool, coinotron with v2.02 ... will test them again with new firmware.... however I will stick to NH at this time because I want to collect BTCs and don't want to wait for confirmations etc...

Also, I see some premium payouts often at NH rentals maybe because of LTC being hot coin now.... so I dont mind selling my hash here in return for BTC upfront, for awhile more.

This confirms what I was hoping to hear, thank you.

The fact that you see any number of Get Failures other than Zero on an active miner tells me its no longer rebooting like it was.

...I just now realized it shows Get Failures = 2 in your screen cap lol.

Hi,
I have A4 (2 ASIC's, one control unit), firmware v. 1.0.2 average speed on nicehash = 200 MH/s

I wrote 2.0.3 firmware on 16 GB class 4 SD card. A4 does not work with it:

What did I do wrong?

Is there any support at Innosilicon to address my question?

Thanks!

You have Batch 2 Units that must be updated to Batch 3 to support current software. Unfortunately this requires you to send the miners off or get on a list to have Innosilicon send you a reflash jig to you to flash the boards yourself.

Here is a thread regarding the reflashing that has some pictures of what the jig looks like on pages 3 and 4.

Unit you perform or receive this update for your miners, they will not run 2.x software

Thank you! Your reply made it clearer for me.

But still want to ask Innosilicon how should I contact them?

I sent my message to two email addresses from their website, and another one I found here. No one answered.

Sorry, please send email to luojm@innosilicon.com.cn, we will check it at once, thanks.

Just found your reply in spam.
I am sorry.

NH is now paying me over 0.1 BTC/day for the 6 x A4s selling Scrypt hash at NH marketplace.

Looks like renting is better than mining, at least for now.

At roughly 40% of your overall hashrate, mine have been cranking out about $32-33 USD a day over on PH so I would estimate your hashrate should make around $80 USD a day at PH based upon last couple of days earnings. At .1 BTC you're making around $115 a day so thats roughly another 30% increase over PH earnings.

I need to get my A4s updated to 2.0.3 it sounds like, lol.
