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

Not getting any MH/s activity with a miner running the new 1.0.3 firmware, other miners on old firmware are still going for it with the drops.

ferk!  

That's a real shame. And on the older firmware how much are you getting? 230-250Mh/s?

Are there any updates from inno? Are they still replying to this thread?

This is getting out of hand real fast..

v1.0.0 dropped a board this morning, v1.0.3 had one board hashing 6mh, but had not figured out it needed to restart to correct this.  Looking at the pool chart looks like v1.0.0 had been this way for most of the night, the v1.0.3 had only been in that state for a short time.  Not sure if I had let it go if it would have corrected it by restarting. I manually restarted both miners.

So I will let these run for most of the day in this configuration.  Then I think I will move pools and leave them with the split firmware and compare on a multipool for a day or two and see how that goes so I can compare the two versions of firmware there.

Is there another thread where someone from inno is answering questions.  Emailed them through their business with no reply.  Is anyone here in contact with inno?

[usao]

My Batch 2 A4's running V1.0.3 have been stable for almost a week, no dropped boards. Still see restarts though.
Running a test now comparing nicehash BTC returns against litecoinpool converted to BTC to see which has better payout.

Other miners run at near enough 280 to start with and drop off to 170ish average (perhaps one blade shuts down and the other continues due to less heat)

Seeing others running 1.0.3 fine i think its best to try re-write the firmware. Can I ask the chap who's got it going successfully what he mounted the boot files with? Cheers

After reading the horror posts here and elsewhere.... I'm relying on a hunch that a few box fans to help get chip temps down may be able to help the avoid restart issues.

I am not expert but my A2s did not have this problem due to much bigger tower chassis and temps are manageable. This new shoebox like chassis design definitely has not been thought through and has become a heat magnet... and it is serious enough to offline boards.

I have discussed with my ISP on my batch of 6 x A4s arriving at their DC next week, and perhaps paying attention to where the A4s are located in the DC to get lowest ambient temps, and getting box fans for good measure to further aid cooling of chip temps.

If all that fails.... let me know where is the tallest bridge, so that I can contemplate jumping off it ...

Well if you think temps are a factor, here are mine; Mine are all between 46c to 50C and I see board drops.

I am running box fans with my A4's and does not seem to help.  My temps according to the miner have never gotten high since the ambient temps where the miners is quite cool this time of year where I run the miners.  So I don't think it is temp related.

Did anyone receive a Batch 3 A4 yet?
I heard they should run more stable ("The software has been optimized again and machines are more stable than batch one and batch two. ")

[bclcjunkie]

question is if it was the software that only needed optimizations why then we still have issues running that firmware on batch 1 and 2... inno is still keeping us in the dark, i mean they don't even bother to update us on the real cause of the problem nor open source the software.

Ive heard about software updates on the forum or from Chloe directly.
Is there an official download site or is this the only way to hear about updates?

[Longsnowsm]

I don''t know of any official download site or way to get notified of updates other than people reaching out directly and Inno occasionally posting something here.

I decided that v1.0.3 isn't any worse than v1.0.0 so I now have both miners running v1.0.3 and have them on a multipool now to see if it will hold together for coin switching.

I have one A4.  One can is cool to the touch, and it doesn't drop boards.  The other is warm to the touch during the day, and it drops boards.  At night, or when the weather is crap outside (cold) the flaky can stays cold enough that it will run for days without problems.

[usao]

Check the fan. I had a bad one and replaced it, now it's working fine.
The CFM rating has to be >= 200.
Other thing to look at is how the heat sinks are mounted. Ive heard that that can be too tight which hurts heat transmission, leading to hot spots around the chips.
If its really bad and you are past warranty period, then consider replacing the cooling paste, or immersing the heat sinks in a non conductive fluid (like mineral oil) to help with heat removal.
Some folks have rigged up AC units with the 5-inch duct work to feed cold air directly into the back of the Antminer rigs, something similar could work here.

I believe it states the normal temp should not exceed 40c and I can say for sure since it has got cold outside mine have been more steady. I wonder what would happen if you flipped the fan to push air instead of pulling the air.

[usao]

I would say, give it a try and see if it makes any difference.
Mine are running fine at 50c not dropping but a very few times this past week.
For me, I do see a pool dependence on how stable the boards are.

I just reversed my fans and it is still early but the first 30 minutes it has dropped the temp by about 2c
I am now running 34-36c down from 36-40c
Please if you try this do so at your own risk.. I will keep you informed on my testing temps with fans reversed after a day or so.

The numbers may be deceiving depending on where the temp sensor is mounted.

[Longsnowsm]

I am seeing a TON of restarts on the multipool, and now one of the miners dropped a board.  Both are running v1.0.3.  The miners do not appear to like the coin switching at all.  I will let it run until tomorrow morning and compare earnings results with Litecoinpool before I decide to switch back.

So the behavior is a lot more unstable depending on the pool.

UPDATE:  I just ran the numbers and crunched down to reward per hour so far and I am quite a bit behind where I would be on Litecoinpool.  Normally my results have shown that I usually end up netting more on Prohashing than I do with a straight pool like Litecoinpool.  But that isn't the case right now.  Looks like the instability introduced is hurting the bottom line.  I don't think I can wait until morning to compare 24hr periods when it is this far behind.  So I think I will be flipping it back and waiting for more updates from Inno.

See my note above about stability being pool dependent.
i compared nicehash and litecoinpool and found my hashrates on nicehash were down around 240 compared to 270+ on litecoinpool. However, the "computed: BTC payout from litecoinpool is about 4% less than nicehash.
After I actually get the LTC converted to BTC I would expect to see further underperformance due to all the exchange fees.
Ill post details on how much BTC I got from each tomorrow.

I'm getting right at the 240 mhs mentioned on nicehash and have been hashing without any substantial drop offs for a full week. I tried cleverhashing which was absolutely terrible on these things. I'm happy with the stable rates and consistent BTC payments from nicehash, only wish is I could hit 280 per miner on a multipool.
