Server Memory Kit

This A-Tech kit provides 32GB of DDR4 ECC registered memory in a matched pair of 16GB modules. It is built for servers and workstations that require registered DIMMs with error correction. The kit is not compatible with desktop or laptop computers that use unbuffered memory.

Registered ECC Requirement

The modules are DDR4 3200 RDIMMs with a 2Rx8 organisation and CL22 latency at 1.2V. Your system must support DDR4 registered ECC memory in a 288-pin DIMM slot; unbuffered or non-ECC platforms will not accept these modules.

Installation Notes

Align the notch on each 288-pin module with the slot key and press firmly until the retention clips lock. Follow the motherboard manual for correct channel population order. The most common issue is installing registered ECC DIMMs into a board that only supports unbuffered memory.

Questions about this item

What does the 3200 MHz speed rating mean once the modules are installed in a server?

The DDR4 3200 rating sets the maximum data rate at 3200 MT/s, so the memory bus can transfer up to 25600 MB/s per module when the platform runs at that speed.

How does the registered ECC RDIMM interface affect what the system can actually use?

The RDIMM places a register between the DRAM and the memory controller, which reduces electrical load and lets the server support higher capacities, while ECC corrects single-bit errors on the fly.

What physical slot and clearance do the 288-pin DIMMs need to fit in a chassis?

Each module uses a standard 288-pin DDR4 DIMM slot and requires enough vertical clearance for a full-height registered DIMM in the server or workstation motherboard.
