new miner, my chains are 11 degrees apart in temp.

any solution to this? my other s5 is only 3-4 degrees apart.

think this might be my power supply cutting power. the other one just did the same thing after I moved cables around. gonna lower the frequency settings see if it helps stabilize it. my outlet is telling me i was using 1207 watts with both at the stock 350m. good thing i have a 1600w psu on the way

What brand/model is your new PSU? It's not so much the watts in some cases but the quality of the PSU.

Sadly cheap PSU's can cause problems.

It is an evga supernova 1300. I have an evga supernova 1600w titanium rated psu arriving today. i have the miner that drops in hashrate underclocked to 325 and it appears to stabilize. at 350m one of the blades intermitently lowers in temp to about 30c and my total Hashrate goes down to 500-700gh. im not getting any errors though. so my thought is that it may not be getting enough power, whoch would explain the temp/hashrate decrease. Im not an electrical engineer so im just guessing...I put in a ticket with bitmain and they want me to take the damn thing apart. and redo the thermal paste.

It's not a bad idea if you know which blade is hotter I woould start with that one. You might just fix it in only one breakdown.

Best news is you have their consent to do it so does not void your warranty. And I'm sure they will help you out. If this does not fix it they will give another good suggestion.

Sucks to go through troubleshooting, but they are a good team to work with. If in China or US you can easily call them and talk to them about the problem.

The weird thing is the blade that is lower in temp is the one that drops in temp to 31c and is probably not hashing full speed. the other blade stays around 60c.

50 - 60 c is nothing out of ordinary on running temp. With it being summer it's hotter in a lot of places aswell.

When it get's in 30's I would guess it is wrong unless very cold ambiant. I would do the thermal paste on that blade first. I'm hoping you can fix it with only one blade needing redone.

Ill do the thermal paste after i get my new power supply today. I want to make sure its not my power supply. Thanks for the info.

If its psu then its broken or something
my evga 1300 working great with 2 antminers s5. So i cant imagine yours cant handle one miner
(edit) i see u r running two antminers too.... so just try only with that nonworking so u will see if its psu or not
If its gonna work with one then maybe u r splitting cables wrong Tongue

that one with 2 pcies should go to 2 boards not only one so its like 1 and half cable for one board

I have one that started doing the same thing. After much troubleshooting with Bitmain, we determined it was the controller. Each board worked fine by themselves but when both were attached to the controller, board 2 would always stop hashing (showed very similar to your pictures except my hashrate was around 500). Hooked both boards to a different controller and no more issues. Hoping to get Bitmain to send me a new board without having to send in my old one first. Want to keep hashing with at least one board if possible.

or bitmain could make longer data cables available so i could hook my second miners' blades upto the miner that is working fine. the one with issues is offline now. and isn't hashing. maybe the controller is messed up. data cables dont reach the other controller currently. are these data cables custom made by/for bitmain or could we source these cables from somewhere else? i prefer to use one controller with 4 board anyway because i wouldnt have to buy a network switch. i could just use the one network cable i have.

Those data cables are very standard and I am SURE you can order them from a electronics place, because I've done it for other things in the past.

SO my power supply just died and wouldnt turn back on. lasted 2 days. luckily my 1600 watt power supply just got dropped off. ill see how this goes...my only issue so fae is the connector wont fit into my kill o watt power meter.
