Figure 2. VID Override Circuit

3.7.1.4
The development kit implements an onboard IMVP-6.5 compliant VR Controller for the
Graphics core supply. The maximum current that can be supported by the core VR is 21 amps.
3.7.1.5
The development kit supports manual VID operation for Graphics VR. A jumper J2C1<pins 1-
2> is provided to enable "GFX VID override" to the Graphics Core VR. The intent of this "VID
override" circuit is for ease of debug and testing. The implementation is similar to the CPU VR
VID over-ride.
3.7.1.6
The development kit supports dual channel DRR3 interface. There are two DDR3 DIMM sockets
(J4V1 and J4V2) on the motherboard. The memory controller supports four ranks of memory
up to 1066MT/s. The maximum amount of memory supported is 8GB of DDR3 memory.
Minimum capacity supported is 512 MB. The on-board thermal sensor is provided for the
DIMMs.
