Hi,

Is anyone able to help me out? I purchased 2 of the S3's and bought the Enermax Triatholor ECO 550W 80 Plus Bronze PSU (one for each S3). It says the DC output is +12V 42A 504W. I hooked one PCI-e connector to one side of the machine and hooked up another PCI-e to the opposite side using only two of the four connections. The machine never reaches over 330 - 340 GH/s. Do I need to overclock this machine to reach the 478 GH/s, or do I need to buy a bigger PSU, or both? If I need a bigger PSU which is recommended?

please post your miner status page

Here are my miner stats

Something is off with chain 2. I've never seen that with the -o and it should be 16 not 32. What happens if you swap the PCI-e connector? If they chains swap info I'd say you have a PSU problem. If they stay the same I would think it's the miner.

The chains stayed the same. I plugged in my second miner and it actually works the way it is supposed to. I switched the PCI-e's to the other two and everything stayed the same with the ASIC. Hooked up the 2nd PSU to the broken miner and still the same problem.

Open it up (5 screws on each side, total piece of cake) and reseat the connector ribbons from the blades to the control board. If you still have the issue you may have one of the blades that is swimming in thermal paste in which case you will need to take off the heatsink (4 screws, not too hard to do but you have to also disconnect the fan because the heatsink has to slide up after you pull it away from the board) and clean up the chips. Or it could just be a bad blade and you will need to talk to Bitmain about a replacement.
