Targeted Server Upgrade

This 32 GB kit (2 x 16 GB) is built for ASRock D1521D4I, D1521D4U-2L+ and D1541D4U server boards. It delivers ECC Registered DDR4 memory that meets the platform’s strict validation list. Builders working with other motherboards or consumer platforms cannot use these modules.

Capacity and Headroom

The pair provides 32 GB at DDR4 2400 (PC4 19200) with CL17 17-17-17 timings at 1.2 V. The boards support up to 128 GB across eight sockets so this kit leaves four slots open for future expansion. Memory will clock down automatically if the installed processor requires a lower speed.

Build Integration

Each stick is a 288-pin 2Rx8 Registered DIMM without a heat spreader, fitting the server board’s standard slots. ECC and registered buffering are mandatory for these platforms; non-ECC or unbuffered modules will not function. The two-module kit populates a matched channel pair for optimal throughput.

Questions about this item

Will these 2400MHz DDR4 modules clock down to match my older CPU's supported speed?

The supplier notes that memory will clock down to run at optimal speeds depending on the processor model installed, so the 2400MHz modules will operate at the highest speed your CPU allows.

How can I verify the ECC registered function is active after installing the 2Rx8 DIMMs?

Enter the server BIOS or use a tool like dmidecode on Linux; both should report the memory as ECC Registered with a 2Rx8 organisation and 1.2V operating voltage.

Does the kit include only the two 16GB sticks or are any brackets or cables supplied?

The package content lists exactly two memory RAM sticks; no brackets, cables or additional accessories are included.
