Topic: A4 Dominator - Pre-Order Group Buy - 280mh, roughly 1000w, $1800 + shipping - page 34. (Read 122577 times)

What I'm curous about is the big surge in LTC difficulty. That can't be due to the mall amount of the group buy and 2nd batch consumer product. So the alternative is the IPO folks
that got their equipment for the profit/at cost million buck investment MUST be behind this jump imho. So the question arises .... ARE they haveing the same firmware issues and
being taken care of on their data hall stuff (assuming it is different then consumer product)?

I can't for the life of me believe this is not so. Because when KNC had issues of this sort on their firmware and launch of Titans a lot of 'big boys' were in the swedish asic miner thread
demanding action in the form of 20-50 posts a half day (there is a reason that thread is so damn large on posts)

I don't see that action on this thread or the main thread for the A4's ...thus wtf..... the only other solution would be another scrypt miner dark data equipment / farm maker

which is unlikely

So I can't see the large IPO investors that may be shooting up the LTC difficulty putting up with these firmware issues without some or most being on the two A4 threads on here
bitching or looking for solutions also. In that I am not seeing this it raises my suspicions that any firmware fixes are going to them first and you guys are on the ass end on the
consumer product.

Also I see not a lot of talk on open source anymore by innsilicon....

not looking too good...at least with KNC all the big and little guys were on the same page to push for firmware fixes the first 3 months..not seeing that here

ASSUMING I am correct (who knows) that the reason for the big LTC difficulty rise IS the IPO folk on the A4 IPO investment getting their data hall equipment up

Just seems fishy as hell...it is TOO guiet if all the A4 customers are in the same boat imho

(then again I am a scar'd refugee from the KNC no support wars..so am likely biased)

Anyway it is troubling to me from the sidelines and I don't even have an A4! (but all so familar from the KNC firmware/support wars)

So at what point is someone going to call bullshit on inno?  If this was knc people would be going nuts right now.  Has anyone gotten any word from inno about all of this and their plan to fix this?

Perhaps Chris@PH can tweak a dedicated port for A4s ....

I do it on PH with the password arguments, it has no effect permanent effect. I believe it helps so I include it but it doesn't 100% eliminate the issue.

has anyone tried setting the diff level manually?

I recall that KNC had issues like these before (correct me if I am wrong) and we have to set diff level manually to work on ceratin pools.

I have nicehash as my secondary and prohash as my primary. However, PH has dropped several times over this last few weeks causing me to mine a little on NH.

I really like prohash but may consider switching to NH as my primary until software updates fix these things.

WOW, 270+ on litecoinpool?  My average is 250mhs on Litecoinpool.  Prohashing seems to be working somewhat acceptably for some people, but not me.  I don't understand the difference.  I posted on the forum over on Prohashing and found I needed to set an option, but even that isn't working.  Just had one miner drop a board and required hard power cycle to get it back.  So I am about to punt out of Prohashing with these miners unless someone comes up with an idea why mine are behaving this way and others seem to work.

I may have to give nicehash a try.

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.

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 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.

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.

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 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.

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 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.

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. 

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?

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.

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. ")
