It's pretty simple. Your rig isn't as stable as you think it is. You need to tweak your settings to see what's going on. I bet you're seeing GPU usage % is fluctuating too.

You likely have one or more of the following going:
-interference between cgminer and a memory intensive CPU miner (PTS for example)
-your clock/voltage settings of one or more of your video cards is not recovering properly following a driver crash
-your OC isn't stable causing the driver crash in the first place
-your PSU is underpowered for the power requirements.

Next thought.  Can everyone please stop referring to WU in terms of MH/s. WU is not measured in MH/s, it's measured in shares/min.

---------------------------------------------

Next thought. It seems the useast server is having troubles. My miners keep failing over to the default west (middlecoin.com) server.

Yup, today payout will be around 0.016 BTC per MH/s, however, that is still higher than "normal"... I'd say anything over 0.05 with 4 MH/s I would consider a decent day :]

I was taking a look to post of the other multipools... Every single one of them as problems. People might say that middlecoin looks like a website coded in notepad but it's ridiculous how stable it is compared to the other pools.


10/10 SO good.

any advice how to get better numbers?

I'm having 5% stales but i see enough people don't having this problem.

eu stratum is down ?

Reduce the intensity to 18 and increase TC to 24000.
