Perfectly?  Are you getting paid perfectly?  Cuz I switched my S4 to BTC Guild over 3 days ago and, while the pool's dashboard does report my speed as just over 2TH and their pretty color charts do show my hashrate fluctuating consistently just above the 2TH line for three days solid now, I don't see to be actually getting *paid* for 2TH...

My earnings so far from this S4 on BTC Guild have been right at half of what I would have expected.  I'm actually earning the same ~$12/day from my S4 on BTC Guild as my two overclocked S3's (1TH) are paying over the same three days, which are still hashing away on Slush's pool.  Both have been running 24/7 since about 1am Oct 5th, with no power or internet disruptions at all.

This has me perplexed.  I know that slush's pool could just be lucky right now, and/or BTC Guild could be unlucky, but slush's posted luck of late has only been kinda good (and I don't see where BTC Guild posts its luck stats, as such) but anyway luck varies from day to day, this 50% of expected payout has been remarkably consistent.  And it seems unlikely that BTC Guild's payout scheme just sucks this much worse than Slush's?  I don't know -- I've never used any pool other than Slush cuz I'm old school like that, and i love their retro 1998-style geeky web design, lol.

I was very relieved to finally switch my S4 to BTC Guild, after researching extensively how to increase UserDiff at Slush's pool (only to find that he'd removed the feature after VarDiff was "perfected") but, at the end of the day, the proof is in the pudding isn't it?  And I ain't likin' this pudding!

Now I'm reluctantly forced to consider pointing the S4 back at Slush's pool since, after 8 to 12 hours, it does finally reach about 1.6 to 1.8 TH there (sometimes, for a while), and that's about .6 to .8 TH's more than I seem to getting paid for from BTC Guild :-(

Anyone else conducting a side-by-side, apples-to-apples earnings comparison between an S4 on BTC Guild and some other proven mining equipment elsewhere?

Thanks!

I noticed the same thing here. Seems like the BestShare is not updating correctly. I tried running the S4 on a local pool and I could see submitted shares difficulties higher than the displayed BestShare in the miner status page.

I turn my S4 off at night, and on again in the morning.

Is there a reason why the highest number for 'BestShare' is always found within the first 45 minutes,
and then the following 12 or so hours it doesn't seem to go any higher? (it has been doing this for four days so far)

So for example,

one day I turn the machine on in the morning, first 45 minutes,
bestshare is found at 7561782, stays at that number for the next 12 hours or so.

another day I turn the machine on in the morning, first 45 minutes,
bestshare is found at 14561782, stays at that number the next 12 hours or so.

Now I understand that it will stay at that number if it doesn't find anything better,
but why is it always peaking during the first 45 minutes and thereafter nothing higher?

I am using solo.ckpool.org and I am just wondering if this is normal.

Just pull the wires from behind the switch and tie them together (short them)

So far - a small 1" square block of wood and a couple bungee cords
wrapped around the S4 to hold the wood block up against the button
is about my best thought. Short of a complete disassembly of the stock
PSU so that I can bridge the switch contacts with a relay or something.

So I have this same problem of power outages for a few seconds every few days that shut off most of my ATX power supplies and requires me to manually switch them.

The IBM DPS2000BB 2000watt server power supplies + sidehack's breakout board (gekkoscience.com) solve this issue completely. All the machines attached to those are really maintenance free and kick back on after the power glitches every time. Just make sure you tie on adequate fans to keep them cool and running.

I know not ideal for S4 replacing the pws but that's most likely what is necessary to solve this problem.

Batch 1 S4 PSU Question
================

I have removed the PSU from my S4 - there is no label or other markings on it.
And I checked all 4 sides. (Yes, I know it's a 1400Watt PSU).

The On-OFF button must be pushed after every power outage.
I asked Bitmain if the PSU could be programmed to return to previous state after a power outage.
I need it to turn on automatically. I need to NOT drive 10 miles after a power outage.

Bitmain's reply - They can do nothing on their side. This functionality is best
incorporated into the PSU directly, and they can't do anything about it.
DUH. A PSU should have an On-OFF switch.
Not a logical On-Off button.

So.....

1. Big UPS capable of 1 hour @ 1400Watts. (Out of the question.)

2. Replace stock PSU. I already have that option available by using 2 server PSU units
   that I already have. I have 2ea. 1200W PSU - they would work fine.

3. Jam something against the on-off switch to hold it in the ON position.

4. Another solution that I haven't thought of yet?

What would you guys do?

Not quite. Rapidly adapting vardiffs also do fine as the ckpool based pools do, but yes they'll hopefully bring out new firmware with the changes I gave them.

The fix for now is to use GHash or BTCGuild with 2048 difficulty. Pools with vardiff seem to overload the miners at the start when spamming them with difficulty 16 shares. A new firmware is on the way soon^TM.

Added warnings to the OP and my guide.

I'm not sure but they're taking quite a bit of the market now. I'll see if I can find a name.

127.0.0.1 will display when its not detecting any network. You can turn the beeper off under Miner Configuration -> General Settings.

Easiest fix is reset, paperclip into the bottom right hole on the LCD for 3 seconds: https://bitcointalksearch.org/topic/m.9071956

I'll try and find out. With BTC price @ $300 though, I wouldn't be too hopeful.

That looks like a PSU problem to me, two boards aren't receiving enough to do much at all and the other two are struggling to keep up. The work that is being done is fine, there's just not enough juice to go around. If you've tried adjusting voltage up slightly then contact bitmain support.

Contact Bitmain support for replacements.

The difficulty issues are firmware related, not batch related and will be fixed shortly.

I'm quite sure you could use these on p2pool if you added +1500 to your username per client.

Going through questions now, bare with me on the spam but I have to separate the different discussion threads otherwise everyone quotes everyone.

Is it better to mine on a p2pool?  What's the difference from mining at btcguild?
