I was except the front plug is on fire hot now on the same board.  Just the wires are hot to the touch while the opposite board shows no sign of heat.

Unplug it don't run if it's "fire hot".  If you do this it's just going to melt the last one and you are literally playing with fire.

Best thing would be to find someone who is able to solder decent, and have them put a new PCIe plug on the melted on.   If you cant find local might ask on board.  But don't run it "fire hot" unless your just looking for trouble.

Like I said earlier.  I went down to one plug on both boards.  The other side front plug and wires are room temp to the touch,  the already melted  side was hot.   What is a reasonable price to pay for another board in us dollars or BTC?  I have had a couple message me and want me to make offers.  

I had another guy in my ltb thread say something about the ground screws and springs but not sure what he ment.


A new board will cost almost half of the units current price.   They are not cheap to get   Going down to 1 and it being fire hot is bad, stop it right now and find solution.

Most likely if you can not solder find someone in services or someone who is known to do it and ship your board to them to have adapter resoldered with new adapter.  This should be a decent amount cheaper then buying new board.

I suspect you have just been unlucky with the quality of the connectors on the PSU cables, where did they come from? If it was mine I would not be selling a perfectly good hash board, spend your money replacing the Board connectors & the PSU cables. As you have already decided do NOT run with a single cable as if the connectors are of dubious quality you will now have twice the current on the remaining connector and it if fail quite quickly.

It's a real easy fix...

Just cut the left side of this off, make sure you know what is + and -, and solder the right side.

If I was not worried about there being more to it i would just take the plug off of an old radeon card I have that i don't use any more.

It was plugged into a surge protector.  I am using a 1300 watt server power supply and the s5 ran fine as did the s3+ I had plugged into the same psu for the last 4 months.  This was kinda just out of the blue.

Sounds like you had an overvoltage or surge.

I do electronic repair and this seems like the current draw, rated in amps, had a spike of over 4 or 5. You shouldn't be pulling this much.

Whats the clock rate?

350, as you can see on the screen shot.

This should be fine, unless the cables he use are very small gauge and the connector themselves are cheap. One connector is fine as per typical watt limits (although i reckon in case of surge you have nearly no headroom.

I'm guessing OP was not using surge protectors.

My s5 melted one plug and now i noticed that the front plug on the same hashing board is ultra hot but the second board is still cool.  Did the one board most likely just go bad?  I went ahead and posted that I was looking for another.  Whats is crazy it is still hashing along like a champ at like 1.2 th/s with all chips working.  I have since unplugged it because I'm sure the front plug will melt also now.

Hmm, maybe they,re cheap connector so the connection was not very good and it caused the electricity to arc and cause heat? Its weird, but if it still run, i think i would keep it running with one connector since i see you're not overclocking. Either that or sell the damaged board for near full price, since a bad connector is minor.
