I only found out about Bitcoin a month ago, I only have 2 S3s for experimental purpose, I am not expecting them to ROI (ordered late (batch 6) and bought coins while they were 600 a pop). using them as heater for appartment, it is cold here already - 18 degrees during day outside.
yes, tried power supply swap. tried moving the units apart, using different power outlets, swapping pci-e ports (now they run all 4 pci-e ports connected) and what not.
the hash rate does sometimes (like the one 30 hour period I mentioned) drop 10% which is below the expected rate.

thank you for looking into it, I think this needs engineer to find the cause of the problem Smiley

here is someone reporting same behavior:

https://bitcointalk.org/index.php?topic=671189.msg8169759#msg8169759

edit: this is offtopic anyway, my question was - does restarting cgminer every 1 hour cause problems with pool shares?

Did you buy them from bitmain or on ebay?  If you got them directly from Bitmain i would call them.  Kinda odd you bought 2 from batch six and they dont look the same. 

JT

They don't look the same, I didn't  catch that !!!!

If they didn't come from Bitmain , then you might of got had.
Someone might have dumped a bad one on you.
I was under the assumption that they were all bought from Bitmain in Batch 6

BTW unless they are completely DOA the return shipping to China is a deal breaker.

Thats what i was thinking he got had.  I know on the S1's you could lower the voltage requirements with a mod or 2 but dont know about the S3's

Hmm, I have 8 S3 and they run like naked ladies in North Dakota all day long.
I forget about them sometimes. Once a week or so I reboot them for good measure.

Your statement is a perfect segue into a question I have!

I will be getting my first S3 any day now and I was wondering how long you let them run uninterrupted?   I'm going to be going on vacation for 7 days in the near future.  Is it safe to let it run while I'm away that long or should I only let it run when I'm around to babysit the unit?

Thanks!

Thats a good question.  I wonder how many miners have had fires back when blades and cubes and thousands of watts.  That being said they can get really hot so maybe not too good an idea.  I leave mine over the weekend but they are in a metal rack with 2 ac units.

@Nikethemutt

When you get the miner in the mail, open up, check cables/connectors inside the miner and TIGHTEN UP ALL SCREWS ON THE HEATSINKS(They loosen up in shipping and don't transfer heat properly so after a few hours you get a demished hash rate if you don't do this). Put cover back on and start mining 24/7. You should do this with any miner before you plug it in. I work offshore for 28+ days at a time and it's all good. I would let run for 24 hours and check before you leave for your trip.(Check for stable hash rate and make sure psu cables/plugs are not getting too hot.

I bought from https://bitmaintech.com/product.htm
they really look different, one has curved heatsinks - the bad one (just like this http://img.youtube.com/vi/VOyrCut0y30/0.jpg), other has straight - the good one. If you are still interested, by the end of the week I will take pics for comparison, I have decided to run them until end of the week without restarts (so will not remove cover - this will require downtime) and see what AVG I get. After I took them down for testing yesterday they both had good 3 hour AVG during night (890 for both), and now it is 5% down as usual for one of the units and going lower (now it is 865), I have a feeling it will stay there and go lower - to 840. I will remind in pm when I have full analysis to those who were interested about this. EDIT: "3 hour AVG for two miners not 865, but 840 already - I think this is what it will stay until I reboot on weekend, so 5% drop for both units, but actually only one is losing speed, which makes it around 10% for that unit"

I only cleaned heatsink on the bad one, it was covered in thick dust layer at the front side (probably the good one is the same, but aint touching it while it runs good), it runs more quiet now after cleaning, but the hashrate AVG behavior did not change.
I already contacted bitmain, they suggested: firmware update (which I did not do, because from what I saw it brings only features I do not need and from what I read for some people it got worse after update), and testing hashboards one by one by disconnecting them which I did not try also.
I agree there is no point in sending back if it is 10% slower than it should be (or rather 5%, because bitmain states that -5% is ok). I was hoping that restarts are good idea, but it seems not - losing shares?

I also tightened screws on heatsinks of the bad unint as one of posters on this page recommended.

So lets wait until I post analysis of running without interruptions and thank you for the interest, did not expect this, my initial idea was just to ask if the restarts is a good idea Smiley

  Do not consider me biased, but I'm with you 6 months and wrote his thoughts aloud. I do not have my equipment and I rent. What I do not understand. We work a day normally, and then 2-3 days money I descend into the toilet. Pools at a slower rate catch blocks, and we in the ass, but I think that our pool is sold us another !!! Who can I check? In addition, I have never read at least one message from a representative pool lately. This is surprising! I do not believe that this can be attributed to luck or to failure, because there are statistics figures. Just tell me I'm wrong, and we did not catch the 6000 + 8 - 10hours, and a pool with a 1500 + catch blocks.
If that is not written, I'm sorry, I did not mean to offend.
And the owners of the pool sincerely advise to reconsider the policy, and that such 20Th I and many others want to leave to others what you do then?

I find it hard to believe that Bitmain would send you a defective dusty unit.  On top of that i find it hard to believe that they would send you an upgraded S1 instead of an S3 like you ordered something is not right there.  I would contact them and ask whats up.

Pool support doesn't monitor this thread you will have to submit a support ticket to them on pool inquires. http://support.bitcoin.cz/Default
I have been here since March and we have lucky periods and unlucky periods, it all averages out over time. This pool isn't for the miner that wants consistent payouts over a given length of time it isn't how it works. The lucky runs where we knock out 10 plus blocks in a day is what makes this a fun pool to mine, it will pick back up and it does average out over time.

In principle, I agree with you my friend, but just in my head does not fit, as Poles with 3000Th found today 8 blocks, and we 6000Th - only 1 Huh

Start here, it's all been covered hundreds of times since 2010.
