About a week ago I upgraded firmware (yes it's old firmware I just never did it). But after a week no problems with the firmware.

One is a little more babysitting with the X's but that was same before. Other works all days if not weeks no problems.

What is the firmware date that you are using now?

I went from stock batch 1 firmware to the "SD-C1-20141217.tar" firmware. So it's retaliative old but I just never got around to doing it.

But it's working for me just as good as stock did, so no regrets on updating.

Anything seem improved that would warrant violating if it ain't broke don't fix it?

With C1 i was not worried since it has micro SD. It's easy to fix if bad flash.

But nothing noticeable fixed. I hoped the one that get's X's and stuff would improve but its the same. One runs perfect for weeks other takes a little time to get up right.

And you've tried swapping cooling systems? Just throwing it out there but I know the disappointment of an iffy miner. The S3 I got from Florida has not only two sub par hashing boards but last change I tried was the controller board with a good s3 and now that runs 440 rather than its usual 441. Not a big deal, haven't even put it back, it's just that the miner seemed to be packed with lower quality stuff. Like one of the inside heatsinks had a stripped screw to start with and the S3 was suppose to be new (but arrived in an opened box from Pines Computer in Florida). Like some farm gathered iffy components. And the first S3 which was good had the factory double strip of heatsink compound on each inside heatsink while the open box 'new' S3 had inside heatsinks fully slathered with heatsink compound.

It is hard to describe you can fix it for a bit by turning it on/off for a bit. You will see others mentioning this before. It's possible heatsink compound might fix it, but I have not went there. I just hate to tear it apart.

It's not the cooling system at this point I would describe my cooling as decently modified. First I use a molex to 3 pin power adapter. Very good quality no issues with it. Then a replacement pump that is a tad faster then the syscoolings one, and has quite a bit more coolant reservoir. Then I added fan's to the back side of the radiator cooling it even more. It is pretty rock solid at this point.

How many watt power supply are you using?

For my second C1, I have the pump and radiator fans going to a separate 12vdc supply divorced from the miner's supplies. You could easily say the heck with the 3 pin connector, cut down a two wire extension cord, splice pump and fans reds to the extension cord lead with the raised ribs and the blacks to the smooth lead then put crimp terminals on the other end and attach to an inexpensive 12 v supply.

When the C1 gets interrupted water cooling it gets hot, current and wattage go way up. Separate supply at least you're sure.

And when you use the inexpensive extension cords from Walmart, e.g. 6', 16 gauge, about a buck forty each, cut off both ends, pick white over brown extension cord so you can easily mark the ribbed side ends with red magic marker and the smooth lead ends with black. Hate connectors with a single color for both pos and neg.
