then limited back to PL1. The power must drop below the PL1 limit before it
allowed to increase back to PL2 again. For time spent above PL1 an equivalent
amount of time must be spent below PL1 in order for it to rise again to PL2. The
maximum time could be as much 2.5x the value of the PL1 Time.
The default values for the CPU are as follows:
PL1: 45W
PL2: 56W
Tau: 28 seconds
PL1 and PL2 can be programmed in watts to any value below the default. Entering a
value above the default will result in the default value being used. Entering 0 also
results in the default value being used.
PL1 Time can be programmed to any number of seconds up to 256, however it is
recommended by Intel to always use the default value of 28. This value maximizes
the effectiveness of the short-term performance boost while ensuring that the life
of the part is not jeopardized by spending too much time above PL1.

3.2.3 Power Management
The VPX6600 module uses the Advanced Configuration and Power Interface (ACPI)
3.0 standard to provide user-managed power via the operating system, contingent
upon the carrier board selected.
The Advanced Configuration and Power Interface (ACPI) provides an open standard
for device configuration and power management by the operating system. More
details about this feature are provided in

.
3.3 CPU
The VPX6600 uses the 2.8GHz (3.7GHz max Turbo) quad-core Intel 6th Gen (Skylake)
Xeon E3-1505Mv5 CPU. This is a 64-bit CPU using a 14-nanometer process with
integrated GT2 graphics and contains direct interfaces for DDR4, DDI, and PCIe x16.
In addition, the Direct Media Interface (DMI) is used to connect to the CM236
Platform Control Hub (PCH).
•
DDR4 ECC SDRAM
–
2 SODIMM sockets support up to 32GB of DDR4 ECC
at 2133MHz. Dual-channel mode is used with 2 SODIMMs. The SODIMMs
are attached to the module firmly with screws and surrounded by heat
sink material to provide a robust mechanism both mechanically and
thermally.
•
PCIe Gen3 x4 (1)
–
Traditionally used for external graphics, but supports
any PCIe device(s). On the VPX6600, this x4 PCIe interface is connected to
an expansion plane fat pipe on the VPX backplane allowing for direct
board-to-board communication with an adjacent slot.
