Server & Workstation Memory Kit

This 64GB kit contains eight 8GB DDR4 ECC UDIMM modules designed for servers and workstations. It is not compatible with desktop or laptop computers. The unbuffered, single-rank design suits platforms that require ECC error correction without registered signalling. Buyers who need memory for consumer PCs should look elsewhere.

DDR4 3200 CL22 ECC UDIMM 1Rx8

Each module runs at DDR4 3200 (PC4-25600) with CAS latency 22 at 1.20V. The 288-pin DIMMs use single-rank x8 organisation and major-brand chips. This specification determines whether the kit matches your system's qualified vendor list. Systems requiring registered DIMMs, different ranks, or non-ECC memory cannot use this kit.

Sustained Workload Reliability

All modules undergo quality assurance testing for dependable operation under continuous load. ECC technology corrects single-bit errors in real time, maintaining data integrity during extended compute tasks. Standard 1.2V DDR4 voltage keeps power draw predictable for densely populated servers. Buyers needing higher capacities per DIMM or registered buffering will not be served by this kit.

Questions about this item

How does the DDR4 3200 speed affect real-world server performance?

The DDR4 3200 rating means the memory controller can move data at the module's rated frequency, reducing latency for multi-threaded workloads and improving throughput in ECC-capable platforms.

What does the PC4-25600 designation tell me about the memory interface?

PC4-25600 is the peak bandwidth label for DDR4 3200; it confirms the modules use the standard 288-pin DDR4 interface and will operate at the rated speed when the platform supports it.

What physical space and slot requirements do these 8GB modules have?

Each module is a 288-pin UDIMM with no heat spreader, so it fits any standard DDR4 ECC UDIMM slot and requires only the usual DIMM clearance in the chassis.
