1  Alternate cryptocurrencies / Mining (Altcoins) / Powering x6 1070 properly on: December 01, 2017, 07:20:52 PM
My setup:
- x6 GTX 1070
- 1600 Watt PSU with x6 (6+2 and 6+2), x5 (stuff with bunch of molex and SATA adapters);
- x6 risers with 6pin
- So far tried to put one of x6 6+2 to power each GPU, use of of SATA adapter to power the 1 riser

Problem:
- It looks like SATA adapters would sometimes try to melt, because when I power on the PSU - it would shut down immediately (I even smelled burned plastic once).

Possible solution:
- Can I just use both 6+2 adapter of each cable, and just put 8pin to power GPU, while use the other 6pin with 6pin extender to power the riser? Will the 6+2, 6+2 cable handle this?



See this image for what I mean:



P.S. Just to be crystal clear: 1 SATA --> 1 riser seems to be fine. But once I try to use 2 SATA on the same cable to power 2 risers (1 SATA to each riser) - the rig power would sometimes not start, and auto halt. I have only 5 SATA/Molex cables vs 6 (6+2, 6+2) cables - so I am 1 cable short for powering 6th riser.

Trying to assemble and run a new rig. Have installed Ubuntu 16.04, GPU drivers, set up 1st card - works fine, mining fine.

Now whenever I add 2nd graphics card - unable to load Ubuntu, getting a screen with errors. It seems that only 1 pci slot works.

Assembled a new rig, Ubuntu 16.04, 1 GTX 1070 - works fine.

Now whenever I add 2nd 1070, unable to load Ubuntu - getting the screen with the messages running for eternity:

4  Alternate cryptocurrencies / Mining (Altcoins) / Simplemining,1070, ZCash - config? on: November 22, 2017, 01:43:45 PM
Using https://simplemining.net/ to control the rig. Have a bunch fo GeForce 1070 GPUs. Would like to mine ZCash from one of descent pools (e.g. http://dwarfpool.com/zec).

How does the config should look like? Smth like:

Code:
-wd 1 -r 1 -epool stratum+tcp://zec-eu1.dwarfpool.com:3336 -ewal wallet_name.rig_name -esm 0 -epsw x -allpools 1 -mport -3333
