User Guide

WELCOME
Thank you for purchasing the MINERDUDE™ X12XTREME™ mining system.
Every unit is thoroughly tested before shipping. This guide will help you troubleshoot the issues you might encounter while setting up the machine.

INITIALIZING SYSTEM DIAGNOSTICS.

X12XTREME has an integrated system diagnostics mode for system health monitoring. AUTOTEST has been built to verify that the system is running normally and to pinpoint issues with an error code on the monitor. This troubleshooting guide will go through the error messages and help you fix these issues.
To enter the system diagnostics wait for the system to initialize. The system will
reboot several times at first, and wait until the system bios have initialized.
To test the fans make sure you have the original SSD that shipped with the system.

  1. Hold the down arrow on the keyboard until you get to the boot selection.
  2. Select OCTOTEST from the boot selection and press enter.
  3. Choose the correct test option by typing the number corresponding to your system.

For X12XTREME, select an appropriate 12GPU option for your system:
3W is for systems with 140mm fans
2W is for systems with 120mm fans
3PSU stands for systems with 3 power supplies
2PSU stands for systems with 2 power supplies
1400W is for systems with DELL power supplies
For example, for a system with 3 power supplies you would select the option:
0) 12GPU_3W_3_PSU
To better understand the results of the diagnostic refer to Page 3

POWER DELIVERY SYSTEM, POWER SUPPLIES, COMPATIBLE CABLES, AND PDU
MINERDUDE X12 and X8 come with various configurations of power supplies ranging from one to four units with ratings ranging from 460W up to 1800W per unit. Verify the specification of your power supply and calculate the rating based on your mains voltage as 110-250v output has different wattage ratings. The system consumes up to 200W at 100% fan speed. Leave at least a 10% power surplus for optimal operation.
The accessories include a power splitter cable. The C13 ends are meant to be plugged into the power supplies. On the other end, you’ll find a C20 inlet that is compatible with properly rated cables and PDUs (Power Delivery Unit).
C20 inlets are rated at 16A/250VAC international and 20A/250VAC in North America whereas C13 is rated at 15A/250V in North America and international at 10A/250V.
Due to the higher rating of the C20 inlet, a properly rated cable and PDU combination must be used. If such a power delivery option is not available to you it is possible to use
individual C13 cables for each of the power supplies.

TROUBLESHOOTING POWER DELIVERY

Refurbished server power supplies are provided by MINERDUDE and tested in stress test cabinets before they get installed in your machine. In addition to stress testing, the output voltages are measured to be within the optimal range. However here are a few tips to pinpoint if you are having any issues with your power delivery.
Make sure your graphics cards’ power requirements don’t exceed the rated output of the power supplies. The power output of the power supplies is dependent on the supplied input voltage. Check the label on the power supply to match your AC voltage to the output rating and add 200W for the system running with fans at 100%. It’s strongly recommended to not run your system over 90% of the maximum power output.

  • Check that the 6-pin cable labeled as PSON is firmly connected to the motherboard and PSU backplane.
  • Make sure each power supply is inserted properly and the status LED is working.
  • If the system keeps crashing remove all but one power supply and remove all but one GPU.
  • If you’re still facing the same issue, replace that single power supply and replace the graphics card with a different one.
  • Reseat RAM into another slot, and make sure it’s properly seated.
  • Unplug the Systems Controller PCIe cable, disabling the fans.

THE DISPLAY DOESN’T WORK / THE BLUE LED BLINKS SLOWLY.
Here are some of the troubleshooting steps to fix an issue in the case of a malfunctioning or nonfunctioning display.

  1. Make sure that the power supplies turn on at the same time from a PDU (Power Delivery Unit). Plugging in the power supplies one at a time may interfere with the normal functioning of the system’s controller.

  2. Make sure that the green LED on the power supplies is working. If the light is not turned on, try taking a power supply from a different slot and see if the LED turns on and that the test mode is working. If this is the case then the issue is most likely with the power supply.
    However, if after swapping the working power supply it also doesn’t light up the LED, then the issue is with the power supply backplane. Inspect the pins of the backplane to see if any of them are bent.

  3. Make sure that the 4-pin cable is firmly connected to the display.

THE SYSTEM WON’T START, NO VIDEO.

To find a cause in a case when the system just won’t start, it’s best, to begin with, the simplest of probable reasons and work your way to the more time-consuming/complex ones, eg. it’s best to check if the power strip is on before changing the RAM.

  • Make sure the power supply LEDs are on. If not, make sure the power supply is fully inserted. Try with just one power supply first.
  • Is the PSON cable connector firmly fastened on the motherboard and the power supply backplane? The motherboard is responsible for turning on the power delivery. If the 6-pin cable connecting the power supply backplane and the motherboard is not securely connected, the system won’t turn on.
  • Are the status LED’s on the front panel working? The Systems Controller is powered by the motherboard.
  • Check if the CPU fan is spinning. If not, press the power button on the front panel or the one on the motherboard.
  • Did you connect VGA properly? Is the monitor powered?

THE SYSTEM WON’T START, NO VIDEO.

  • Make sure each power supply is inserted properly and the status LED is working.
  • If the system keeps crashing, remove all but one power supply and remove all but one GPU.
  • If you’re still facing the same issue, replace that single power supply and replace the graphics card with a different one.
  • Reseat RAM into another slot, and make sure it’s properly seated.
  • Unplug the Systems Controller PCIe cable, disabling the fans.

SSD
Each MinerDude is tested before shipping. Issues with the boot media are most likely shipping related or can happen when the SATA cable gets disturbed during the initial setup. If the boot drive is not detected, try disconnecting and connecting the drive. In case that doesn’t help, make sure that both of the SATA cable connectors are securely fastened. If the machine is still booting into the bios screen, reconnect the SATA cable to a different SATA header on the motherboard.
THE MACHINE CAN’T CONNECT TO THE INTERNET
After making sure the ethernet cable works, proceed to check if the gray ethernet cable labeled in gray as “6” is firmly connected to both the motherboard and the systems controller. If this doesn’t solve the issue see if the port on the rear of the machine works.

OTHER ISSUES WITH THE FRONT PANEL:

Some issues can not be displayed through the systems controller, TESTMODE.
The following issues that might happen are:
NO IMAGE IS DISPLAYED ON THE STATUS DISPLAY.
This issue can occur when the display cable has come loose. Make sure that the connector labeled in mint green as “7” is firmly connected to both the OLED panel below the systems controller, as well as the systems controller itself.
THE USB ON THE FRONT PANEL IS NOT WORKING.
This issue is most likely related to the Black USB cable between the motherboard and the systems controller. Make sure the cable Labeled in green as “USB” is firmly connected.

THE RESET AND POWER BUTTONS ARE NOT WORKING.
This issue is caused by the power header cable being loose or damaged. Make sure the red-tipped cable labeled in red as “3” is firmly connected to the motherboard as well as on the system’s connector.
THE SYSTEM DOESN’T TURN ON.
This issue can be caused by a loose Front Panel connector. Check for the graphic on the next page and see if the cable labeled in mustard yellow as “F-Panel” is firmly connected between the motherboard and the system controller.
Check that the 6-pin cable labeled as PSON is firmly connected to the motherboard and PSU backplane.
GETTING ACCESS TO MOTHERBOARD CONNECTORS CPU AND RAM
In order to troubleshoot some of the issues, removing the power supply guide bracket is required. In order to do so, first, remove the power supply by pushing down the rubber tab and pulling it out. Pull out the power supply and unscrew the 6 screws on the right side of the machine, as shown on the diagram. Carefully remove the guide bracket to gain access to the motherboard.

FIVE FAST BEEPS ON THE BOOT.
While the machine beeping on startup is normal, five fast beeps right after turning on the machine might mean the RAM module is either loose or defective.
Remove the power supply guide bracket and re-insert the RAM. Make sure the connector clicks on both sides at the same time. If it doesn’t work after that it is worth trying again, just to make sure it’s a RAM and not just a connection issue.
DETECTION OF GRAPHICS CARDS.
MINERDUDE X12XTREME supports all available PCIe graphics cards and provided driver support for the OS.
If none of the cards are detected the issue is most likely related to drivers. If updating drivers is not solving the issue, go to the BIOS by pressing the DEL key on boot and change the PCIe version to Gen 2.
If one or a few of the cards are not detected.
To find the graphics cards that are not being detected, boot the system with a single card first and keep adding one card at a time for each boot. Once a non-functioning PCIe slot/GPU is found try a different GPU and PCIe power cable. If there’s still no card detected contact MinerDude support.
SYSTEMS CONTROLLER NOT WORKING
After powering on, the motherboard boots and sends a signal to the systems controller.
You should see the Blue LED light up for a moment, after which the OLED will display the start screen.
The systems controller won’t turn on if the motherboard is not turned on. Try clearing the CMOS by pressing the clear CMOS button on the front panel.
If the systems controller is not turning on even though the motherboard is working, try disconnecting the USB header from the systems controller and plugging it back in. You should see the blue LED on the front panel light up for a moment followed by the OLED turning on.
If the OLED is not turning on disconnect the front BME temperature sensor and the 4-pin power supply backplane data cable. Remove and reconnect the systems controller USB header.
