How to get the board working.
.
You need:
-
4x ecc reg ddr2 sticks inserted in CPU0_DIMM1~4
-
4 x 8346HE, 8356 CPU (that we know so far, my guess is newer won't work)
- Any
single-slot backplate video card, or any
dual-slot card with the end cut off (the second slot is over the power button, removing the power buttons caps should work too)
-
sata dvd drive connected to SATA20 OR
usb boot "acpi" drive.
-
sata hard drive connected anywhere else.
-
Power supply with a few 8-pins EPS or pcie connectors, or adapters (you need a total of to fill 8x2 and 7x2 pin)
- Jumper the power supply ON (green wire to any black ground wire)
- OS with 16-core support. Ubuntu 9.10 AMD64 for example.
Step 1
You need to fill CPU0, and CPU0_DIMM1~4 to boot.
To install 8 sticks fill CPU0_DIMM1~4 and CPU1_DIMM1~4.
Fill the two power connectors, leaving the 4 pins on the right empty. You can use PCIE connectors if you connect them backwards or molex-eps adapters.
Step 2

During installation, hold DEL. Go to boot option, change Priority 1 for "DVD-ROM" or "THUMBDRIVE USB", Save and Exit.
*When installing Linux enter noacpi before installation. (Ubuntu, press F6 and check "acpi=off")
*Haven't tried installing windows7/server you might need to use the shell.
Step 3
Shutdown. Connect the hard drive in SATA20. Power up, hold DEL, change "Hard drive Priority BBS" to "HARD DRIVE xxxgb". Change Boot Priority 1 for "HARD DRIVE xxxgb", Save and Exit.
The OS should start, if not recheck acpi settings in bios/installer.
Step 4
If you're using Ubuntu, update the OS and
enable sensors with "sudo apt-get install lm-sensors". Install GKrellM System Monitor, System Profiler to see reported temps. Install Cpu Frequency Monitor to force the CPU at full speed for benchmarks.
