Motherboard hardware list

  • AMD K8
  • VIA K8T890
  • VIA VT8237
  • W83627EHF
  • ICS ICS953202
  • Semtech SC2643VX

Motherboard GPIO configuration

It seems only GPIO2 and GPIO5 is used from W83627EHF/EHG. VT8237GPIO is perhaps used for CABLE select and with GP0 one can blink the power LED.

GPIO2 (0xE4)

No inversions, bit0 and bit1 inputs, rest configured as outputs.

GPIO2 bit7

memory voltage select

GPIO2 bit 6

memory voltage select

GPIO2 bit 5

1 = vcore offset + 100mV 0 = vcore offset + 200mV

GPIO2 bit 4

1 = 1.5V Chipset voltage 0 = 1.6V Chipset voltage

GPIO2 bit 3

0 = VID can be changed 1 = LockVID

GPIO2 bit 2

output always 1 ??? maybe it is connected as turbo# on clock chip.

GPIO2 bit 1

unused input (set to MOSI/MISO in CR29)

GPIO2 bit 0

unused input (set to MOSI/MISO in CR29)

GPIO5 (0xE1)

bit5 and bit0 are outputs, rest is not used as GPIO. No inversions. CR2D is 0x21 it means only GP50 and GP55 are used for GPIO.

GPIO5 bit5

memory voltage select

GPIO5 bit0

memory voltage select

Memory voltage adjustment
