New System Features With Opteron 4200 Series
Processors
• Application Power Management — The Thermal Design Power (TDP) of the
processor denotes its power consumption. This feature optimizes system
power consumption.
• Turbo CORE /Core Performance Boost — Boosts all core frequencies when
additional TDP is available in a given workload. With lightly threaded
workloads, half the processor cores enter C6 sleep state thereby enabling
higher speeds.
• The processor frequency drops to 500 MHz when the system is idle to reduce
power consumption.
• Performance Monitoring Counters — The Northbridge P-States (performance
states) allows more users to access the performance monitor counters at the
same time. This feature reduces power consumption and optimizes
performance within the specified TDP.
• System Memory:
– Low Voltage Memory Modules (DDR3L DIMMs) — The Opteron 4200
series processors support DDR3L DIMMs at a lower operating voltage of
1.35 V.
NOTE: BIOS setup options allow you to control frequency and voltage
configurations within allowable limits.
– Memory Speed — DIMM speeds up to 1600 MHz is supported. If
memory modules with different speeds are installed, they will operate at
the speed of the slowest installed memory module(s).
