DDR4 Memory

The conga-TS175 supports DDR4 memory modules up to 2400 MT/s. The DDR4 memory modules have lower voltage requirements with higher
data rate transfer speeds. They operate at a voltage of 1.2V. With this low voltage system memory interface on the processor, the conga-TS175
offers a system optimized for lowest possible power consumption. The reduction in power consumption due to lower voltage subsequently
reduces the heat generated.
Note
Use memory modules with same specifications, same type and model.
