1.4 System Memory
1.4.1 Overview
The motherboard comes with two 288-pin Double Data Rate 5 (DDR5) Dual Inline Memory
Modules (DIMM) sockets.
DDR5 memory brings several key performance and power gains to the table, as well as new
design challenges.
From the JEDEC JESD79-5 DDR5 standard, DDR5 specification has significant
improvements in capacity, speed, and voltage. Structure-wise, the Power Management IC
(PMIC) is moved onto the DIMM, reducing redundant power management circuitry on the
motherboard for unused DIMM slots in previous generations.
The DDR5 specification is bringing the maximum potential capacity for a single DDR5 DIMM
to 128GB, a theoretical maximum transfer speed of 6400MT/s which is doubling the rate of
DDR4, along with the improved power consumption as 1.1V.
