Hello,

has anyone had issues with their Neptune cubes not hashing? basically being completely dead? long story short, I recently got some busted up Neptunes off ebay that listed that they may or may not work. well the only thing that works is the controller board, but all 5 Neptunes are dead. They are detected by the board though, but do not start hashing at all. additionally, the 'advanced' page shows some VRMS with 0 current output, but it seems the temp sensors are working, however the wattage never jumps up past 10 watts or so on any board. I loaded 1.06s and I was hoping to just dust them off, and have them start up, but no luck. I will take any and all troubleshooting advice at this time. thank you!

I'm not too familiar with them, but they look like dead cores or dead VRMs to me.
Some users here may be able to explain how you can tell the difference between dead core and dead VRM.
Some of my cubes have only 6 or 7 of the VRMs actually showing a normal voltage and amp value.
Some are either very low voltage or very low amps, but I don't care that much since I paid them knowing they weren't perfect.

If by chance you're in EU, I may be interested to buy the full unit (cubes+controller) depending on what you are asking.
One day, I'll find some time to play with the dead units I've collected.

thank you for your reply. I am still playing with them, and hoping for the best still. However, i have been messing with their commands in SSH mode, in particular what 'waas' tells me...here is what i get at this point...

i have 4 modules plugged into ports 1-4 on the controller and it seems it is having problems updating the modules' frequencies. I will post more details later today when i get home.

I am having this problem with my 2nd batch neptune's and suspect it might be the fans not being the same as the first batch. I would love to find someone as well who is still making the kits so i can put fins on all my VRM's but that doesn't look its going to happen unless I get really crafty which I am not good at doing. Sad

why would you think the fans would be the problem?   You can do you own cooling and disconnect all the fans that it came with

So what do you think the problem is?
