My 3 Days with 2 S4's

Both of my S4's are running stock settings and always read ~2TH/s on the miner.  The poolside hashrate is very different though.

24 Hour on Eligius: ~100GH/s

24 Hours on Eclipse: 1600-1700GH/s

24 Hours on BTC Guild: ~2TH/s (after manually setting the diff to 2048)

The problem seems to be that the pool and miner are not resolving the dynamic difficulty properly.  Eligius stick to 128 and results in sh*t for hashrate.  Both Eclipse and BTC Guild settle on 1.8k for the difficulty and yield 1.6-1.7TH/s.  If you manually select 2048 from the difficulty menu on BTC Guild I get 2TH/s poolside.

NO ONE IS STEALING YOUR HASHRATE.  The firmware obviously needs some work in order to properly resolve the variable diff.  In the meantime i'm obv mining on BTC Guild with 2048 Diff manually selected.

I'm not looking for a solution, or troubleshooting help from anyone as i've alread done the necessary troubleshooting.  (ie factory reset, cable swaps, settings, blah blah)  I'm just presenting data of my experience with 2 S4 miners and confirming there is a problem.  I can provide screenshots, but don't really think I need to waste my time with that.


TLDR;
Mine on BTC Guild and manually set the difficulty to 2048 until the new firmware is released.

Hello I have 2 S4's and prefer to use Eligius, but I'm also having tons of trouble with that combo.  I don't have any solutions, but wanted to provide data from my equipment for confirmation of the problem.

TESTING:
      Run the miners on separate pools for 5 minute increments and compare results.  I also have 2 S3 Upgrades running in the same 5 min increment for comparison.  All 4 miners are restarted together then when they read 5 min of uptime i took a screenshot of MultiMiner, which shows all the details.

Below is a link to 2 screenshots of the S4s running on Eligius vs Eclipse.  Note the accepted shares and "Effective Hashrate"

If the link doesn't treat u well, here is the data.

THE 5 MINUTE HASH    (sounds like breakfast)            
ACCEPTED SHARES            
   S3A   S3B   S4A   S4B
Eclipse   145   144   328   272
Eligius   149   187   48   57
            
EFFECTIVE HASHRATE            
   S3A   S3B   S4A   S4B
Eclipse   525GH/s   428GH/s   1650GH/s   1610GH/s
Eligius   407GH/s   426GH/s   89GH/s   106GH/s
