Hello everyone
Hopefully someone can help me.
I rigged up my first 3 s3's last night and they were running at about 450gh/s, so all OK.
Overnight they all went down to about 200gh/s, so I turned them all off and started them again - they then went up to 450gh/s again.
They have been working for about 4 hours and now one of them has reduced again, but at the moment the other 2 seem to be OK.
Any advise would be great! They are new from Bitmain yesterday,.
Thanks
Adam
It is possible it could be more simple depending on what PSU you are using.
I have Corsair AX860's running all of my S3's. They have a "hybrid/normal" switch. When I flipped that switch to "hybrid" on a couple of my PSU's, I had one board on several rigs stop working. My hashing power on each of those rigs cut in half. However, it worked fine when I turned off the power to the PSU and turned it back on. They would work fine for several hours. Then all of a sudden I get an alarm from the pool saying hash is down. I would look at the rig setting off the alarm, only to see the hashing rate was half of what it should be. It ended up being the "hybrid/normal" switch. When I flipped the switch to "normal," I have not had a problem ever since.
With that said, "Hybrid" probably limits the amount of power given to the rig once the PSU reaches a certain temperature. Hybrid makes the fan on the PSU turn at less RPM's. So, if you do not have Corsair's with a "hybrid/normal" switch, it may be your PSU is not sufficient at providing the power needed to the rig(s).
Still pay attention to Dogie. He knows what he's talking about.
