Gravitymaster’s SMOS FA

Note: I do not work for SMOS this is all IMO

Why is AMD cards slow on SMOS?

• As of 8.29.2017 AMD has NOT released drivers for Linux (what SMOS runs on) thus does not fix the DAG issues which was resolved under Windows.
• Check the AMD website for updates don’t ask on the chat rooms, I am sure it will be posted when it comes out!
• Link to AMD discussion

Why are cards not showing up in SMOS?

• Make sure to update the latest BIOS!
• If Motherboard does not have these options the amount of cards will be limited
  • Enable 4G encode
  • PCIe support to Auto or GEN2
• Test one card/riser at a time to make 100% both are working then add the next cards/riser rebooting each time to confirm things are working.
• Power each card of only one PSU! Do not put power from one PSU to GPU and power from other PSU to riser. This causes strange problems.

Why are Overclock / FAN not working when I set them?

• Both Over Clock settings need to be set, do not level them blank use 0

Why does SMOS keep rebooting?

• Most likely Over clock is set to high. Start by setting core and memory to 0 and let the system run for a hour. If all is well use the follow as a starting point and go up or down as need:
  • GTX 1060 - Core 0 / Memory 1100 (23-24Mhz at 70 Watts)
  • GTX 1070 - Core 0 / Memory 1200 (30-31Mhz at 115 Watts)
  • GTX 1080TI - Core 165 / Memory 0 (ZEC 700Mhz at 180 Watts)

How do I overclock each GPU at different values?

• You can set them to different values using a comma between each each setting for example:
  • 1000,1100,1000,800,900,900

Why does SMOS Crash

• Don’t use low quality USB. Some mining software uses more disk access than others (Claymore uses RAM where Etherminer uses disk) and will wear them out quick. The price of a good USB is the cost of a 120GB SSD, I would go with the SSD.

How many cards does SMOS Support?

• SMOS supports up to 15 cards but most motherboards have a hard I/O limit of 13 when using PCI expanders.

Power info

• PSU are at peak efficiency between 55% and 60%, will also create a lot more heat when above 75%. Buy large PSU and use 60-65% of rated power.

How do I add a new miner to SMOS?

• Request anything like this in the #SUPPORT channel do not spam th #GENERAL Channel

• SMOS is running linux, you can compile and install new miners any time you want.

  • Also can integrate into the SMOS GUI by replacing old miners under /root/miners_org/

How do I see the running miner via SSH?

• screen -x miner

How to change email address via SSH?

• nano /mnt/user/config.txt
