Server DDR3 LRDIMM Kit

This 256GB kit contains eight 32GB DDR3 1866 modules built for servers and workstations that require ECC Load Reduced memory. The quad-rank 4Rx4 organisation and CL13 latency suit high-capacity configurations where registered DIMMs are mandatory. It is not for desktop or laptop systems, nor for platforms that accept only standard unbuffered or registered DDR3.

Installation Notes

Each module uses the 240-pin DDR3 DIMM form factor and operates at the standard 1.5V, so physical insertion follows normal server DIMM procedure. The common issue is mixing LRDIMMs with RDIMMs or UDIMMs in the same channel, which the platform will reject. Follow the system manual for correct channel population order and ensure all slots receive identical modules.

Pre-Order Checks

Verify that your server or workstation explicitly supports DDR3 ECC Load Reduced DIMMs at 1866 MT/s and can address 4Rx4 quad-rank modules. Confirm the maximum memory per socket and the total number of supported DIMM slots so the eight-module kit can be fully populated. Check the qualified vendor list or system documentation for any rank-per-channel limits before ordering.

Questions about this item

How do I verify the kit is running at 1866 MHz with CL13 after installation?

Enter the system BIOS or UEFI and confirm the memory frequency shows 1866 MHz and the CAS latency reads CL13; the modules operate at 1.50 V standard DDR3 voltage.

What exactly ships in the box and is anything else required?

The box contains eight 32 GB DDR3 240-pin LRDIMM modules for a total of 256 GB; no additional parts or cables are needed for installation.

Should I choose this 8×32 GB quad-rank kit or a different capacity for my server?

Select this 256 GB kit when your server supports DDR3 1866 ECC LRDIMM 4Rx4 modules and you need the full 256 GB across eight slots; otherwise match the capacity and rank your platform specifies.
