Server DDR4 64 GB quad-channel kit

This 64 GB kit contains four 16 GB DDR4 2666 MHz registered ECC DIMMs built for servers and workstations. Each module runs at 1.2 V with CL19 latency and a dual-rank x4 organisation. The 288-pin form factor fits DDR4 RDIMM slots only.

For DDR4 registered-ECC platforms only

Suits administrators upgrading compatible DDR4 servers or workstations that require registered ECC memory. Not for desktop or laptop systems, which use unbuffered non-ECC DIMMs and will not accept these modules.

Straightforward DIMM installation

Insert each module into the correct channel slots following the system manual's population rules. Common issues include mixing registered with unbuffered DIMMs, populating slots in the wrong order, or exceeding the platform's maximum supported capacity per channel.

Pitanja o ovom artiklu

Does my server or workstation need DDR4 RDIMM slots to use this 288-pin ECC registered kit?

Yes, this kit requires a system that supports DDR4 registered DIMMs with 288-pin slots and ECC functionality. It will not work in desktop or laptop computers that use unbuffered memory.

Can I mix these 2Rx4 dual-rank modules with existing single-rank DDR4 RDIMMs in the same server?

Mixing dual-rank 2Rx4 modules with single-rank DIMMs is possible if the platform supports mixed-rank populations, but you must follow the manufacturer's channel and slot population rules for stable operation.

How can I confirm the kit is running at the rated 2666 MHz CL19 after installation?

Enter the system BIOS or use a hardware information utility to verify the memory frequency shows 2666 MT/s and the CAS latency reads CL19 at 1.20 V.
