Target Server Platform

This 64 GB kit is built for ASRock server boards EPC612D8, EPC612D8A, EPC612D8A-TB and EPC621D8A. It suits administrators upgrading registered ECC memory in those specific platforms only.

Registered ECC Requirement

The modules are DDR4 2400 RDIMMs with CL17 timing, 2Rx4 organisation and 1.2 V operation. They will not work in systems that require unbuffered non-ECC DIMMs or that forbid registered memory.

Thermal and Power Profile

Bare modules without spreaders run at standard DDR4 voltage, so power draw stays low and cooling relies on chassis airflow. No active cooling is needed under normal server workloads.

Questions about this item

What does the DDR4 2400 speed mean for real-world throughput on the ASRock EPC612D8?

The modules run at 2400 MT/s with CL17 timing; actual bandwidth depends on the installed CPU and the board's memory controller configuration.

How does the PC4-19200 rating relate to the memory interface on these server boards?

PC4-19200 is the JEDEC designation for DDR4-2400; the EPC612D8 and EPC621D8A platforms use a 288-pin registered ECC interface that operates at this speed.

What physical clearance and slot layout are needed to install the two 32 GB sticks?

Each stick is a standard 288-pin registered DIMM without a heat spreader; the boards provide eight DIMM sockets, so the kit occupies two of them.
