Kingston ValueRAM's KVR1066D3S8R7SK3/3G is a kit of three 128M x 72-bit 1GB (1024MB) DDR3-1066 CL7 SDRAM (Synchronous DRAM) registered w/parity, single-rank memory modules, based on nine 128M x 8-bit DDR3-1066 FBGA components per module. Total kit capacity is 3GB (3072MB). Each SPD is programmed to JEDEC standard latency 1066Mhz timing of 7-7-7 at 1.5V. Each 240-pin DIMM uses gold contact fingers and requires +1.5V.
TS ON DIMM
TS (Thermal Sensor) on DIMM is a closed-loop throttling technique that offers a more advanced approach to system thermal management through the use of a physical thermal sensor to further reduce guardband present in the existing methods. The reduction of guardband has a direct and positive impact on system performance.
Overview of TS on DIMM
Instead of using power prediction to estimate the temperature of the DRAM case, TS on DIMM uses a physical thermal sensor integrated on the DIMM module to monitor the temperature of DIMM. If the thermal sensor detects that the DIMM temperature is exceeding a programmable critical trip point, it triggers an event signal that tells the memory controller to throttle the memory traffic, thereby reducing the DRAM case temperature. The addition of a physical thermal sensor results in a closed-loop throttling methodology that allows for real-time throttling based on the measured temperature. This closed-loop methodology leads to reduced guardband primarily due to the ability to sense ambient temperature. Most of the guardband present in existing throttling mechanisms is due to their open-loop policy, which means that since they do not receive feedback on the actual ambient or DIMM temperatures, they must always assume the worst-case scenario. TS on DIMM provides the needed temperature feedback and allows the system to hold off on throttling until the actual DIMM temperature reaches a programmed critical temperature trip point. The closed-loop policy offered by TS on DIMM is what allows it to reduce the guardband over existing memory throttling methods. |
