Hi!

Im a new miner from Spain, Barcelona. Best regards for all! Smiley

I have two questions. I hope you can help me because i dont have any idea to find the solution of my problems.

I have one Antminer S3 B3 and one is working with 2 PCI Connectors @250Mhz and hashs at 500gh/s but in one hour and a half the hash decreases to 360-380 gh/s. How is it possible? The status of miner appears to be OK, without any "X" or "-"... Somebody knows whats happening? Sad if i reboot the S3 the hashing push up to 500GH/s but in one hour and half decrease too... Sad
In the status no HW errors and nothing strange. Only i can saw is a Little decrease of temperature... 47-44 grades @500GH/s VS 46-40 @365-380 GH/s.  

I observed that my miner works more stable with 2 PCIEX connectors tan 4. How is it posible??

And the second question is for the second S3 B3.

I tested 250Mhz, 237Mhz, 225 and default 218.75 but always i get a lot of HW errors. How can fix the HW errors?? The only speed that no cause HW errors is 212Mhz.
I think the temperature is not the problema because its working at 43-43 grades.

Two S3 antiminers are working with the last available firmware of Bitmaintech and are new. Arrived this week.

Can you help me? Sad

PD:I hope you can excuse my English


Anybody? Sad

The reason no one has responded is because your issues have been covered multiple times in this very thread. Your symptoms are exactly the same to what many of us here are experiencing.

At this time the only things that have a CHANCE of helping are re-pasting the heatsinks and setting up a restart routine.
Since I've added '/etc/init.d cgminer restart' to my crontab I've seen my 24-hour hashrate increase from 410 to 480 on my GOOD units. From 398-420 on my "Bad" units.
