  • Intel VR13 DC-DC converter specifications.
  • Intel SVID protocol.

Used for Vcore power regulation for Intel VR13 based microprocessors

  • Servers, Workstations, and High-end desktops

PXM1310 is a Multi-rail Controller and it is compliant to

  • Intel VR13 DC-DC converter specifications.
  • Intel SVID protocol.

Used for DDR3/DDR4 Memory power regulation for Intel VR13 andIMVP8 based systems

Usage Notes

This driver does not probe for PMBus devices. You will haveto instantiate devices explicitly.

Example: the following commands will load the driver for an PXE1610at address 0x70 on I2C bus #4:

# modprobe pxe1610# echo pxe1610 0x70 > /sys/bus/i2c/devices/i2c-4/new_device

It can also be instantiated by declaring in device tree
