Intel i5-4300Y CL8064701558601 Data Sheet

When a physical thermal sensor is not available to report temperature, the processor

supports Open Loop Thermal Management (OLTM) that estimates the power

consumed per rank of the memory using the processor DRAM power meter. A per rank

power is associated with the warm and hot thresholds that, when exceeded, may

trigger memory thermal throttling.

Scenario Design Power (SDP) is a usage-based design specification, and provides an

additional reference design point for power constrained platforms. SDP is a specified

power level under a specific scenario workload, temperature, and frequency.

Intel recommends setting POWER_LIMIT_1 (PL1) to the system cooling capability

(SDP level, or higher). While the SDP specification is characterized at Tj of 80 °C, the

functional limit for the product remains at Tj

MAX

. Customers may choose to have the

processor invoke TCC Activation Throttling at 80 °C, but is not required.

The processors that have SDP specified can still exceed SDP under certain workloads,

such as TDP workloads. TDP power dissipation is still possible with the intended usage

models, and protection mechanisms to handle levels beyond cooling capabilities are

recommended. Intel recommends using such thermal control mechanisms to manage

situations where power may exceed the thermal design capability.

Although SDP is defined at 80 °C, the TCC activation temperature is 100 °C, and may

be changed in BIOS to 80 °C.
