Power connections for Siemens Primergy 470 motherboard D1031
This board will work fine with a standard ATX power supply (300 W and higher) that has the extra connector for auxiliary power (AT style pins 1,2,3 = ground, 4,5 = 3,3V, 6 = 5V).
1 connector = standard ATX
1 connector = auxiliary 3,3/5V near CPU\'s, you must have this one connected.
1 connector = monitor connector (next to the ATX connector, tis is for remote control and information) This one is not needed for normal operation, no connections to be made.
If you use 1 CPU you do not need a VRM module. It is advised to plug a termination board in the slot of the second CPU but in my experiance it works fine without this.
If you use 2 CPU\'s they must be matched pairs (same stepping number) and you must use a VRM module. VRM\'s are standard modules and available from many suppliers.
The VRM modules for the Katmai processors (up to 550 MHz) and for the Coppermine processors (500 - 1000 Mhz) are not the same. Make sure you get the suitable one. You won\'t damage the board or the VRM but the CPU\'s wont start.
To get the system running you must connect some pins on the control panel connector (the 20 pin connector right to CPU2)
Pin 1-2 = Standby Led 2=(+)
Pin 3-4 = Power Led 4=(+)
Pin 5-6 = HDD Led 6=(+)
Pin 7-8 = Reset
Pin 9-10= Power On/off
Pin 11-12-13-14 not used
Pin 15-17 environment temperature (sensor LM35 15=GND, 16=Vout, 17=Vc, 18 not used)
Pin 19-20 Door open
You must put a jumper on pins 15+16 and also on 19+20 to make the board think that the temperature is OK and the door is closed.
Pin one is the one closest to CPU2 (view from top of board)
2 4 6 8 etc...
0 0 0 0
0 0 0 0
1 3 5 7 etc ...
Under the control panel connector there is a smaller connector with 6 pins. You must bridge pins 5+6. Leave the others open.
When you plug in the power supply the on/off switch will only work after 10 seconds.
Internal USB connector (next to switch block)
pin 1 = USB power (pin closest to swithc block)
pin 2 = open
pin 3 = -Data
pin 4 = +Data
pin 5 = GND
The on board SCSI controller is quite performant with LVD drives (80 Mbyte/s). You must use a cable with an LVD termination module or an SCA drive bay which also has this LVD termination.
The Intel 440GX AGP chipset supports ACPI but Windows XP does not recognise it. I saw it working on these boards with Windows NT4.
The boards with the number D1031 A22 GS1 do not support Coppermine CPU\'s.
(but GS2 and higher do). As far as I could see the only difference (after updating the Bios)is in 4 electrolytic condensors :
Close to CPU1 :
8 elco\'s (1 = closest to SDRam)
1,2 and 4,5 and 7,8 : same on all boards 1500µF/6,3V
3 and 6 : GS1 = same as above, GS2 and higher : 820µF/4V
Close to CPU2:
4 elco\'s (1 = closest to SDRam)
1 and 4 : same on all boards 1500µF/6,3V
2 and 3 : GS1 = same as above, GS2 and higher : 820µF/4V
The board does not work with some ATI cards (AGP, Radeon).
It does work with Nvidia TNT2, Matrox G200.
SDRAM must be ECC Registered, standard SDRAM will not work.
When you install Win XP, better set the bios for "non-plug&play".
Even then a driver will be missing, you will find an "Unknown Base Device". You will need the driver "FSC Multiprocessor Interrupt Controller" to correct this.
Success!
