16GB DDR3 ECC UDIMM kit

This 16GB kit contains four 4GB DDR3 1866 modules rated at PC3-14900 CL13. ECC unbuffered operation suits workstations, servers and NAS systems that require error-correcting memory. JEDEC-standard 1.5V voltage ensures broad compatibility with supported desktop and server platforms. The black modules ship without heat spreaders.

Straightforward DIMM installation

Each 240-pin DIMM seats in a standard DDR3 UDIMM slot; no tools beyond opening the chassis are required. Because the kit is unbuffered, populate slots according to the motherboard manual to enable dual-channel operation. Mixing with non-ECC or registered DIMMs will prevent boot or disable error correction. Verify that all four modules are recognised at 1866 MHz after seating.

Confirm DDR3 ECC unbuffered support

Check that the target system accepts DDR3 ECC unbuffered UDIMMs at 1.5V and can run four ranks per channel if fully populated. The motherboard or server documentation must list PC3-14900 or 1866 MHz as a supported speed. Ensure the BIOS is current enough to initialise the full 16GB capacity. Do not order for platforms that require registered or load-reduced memory.

Questions about this item

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

Open the BIOS or UEFI on first boot and confirm the memory frequency reads 1866 MHz and the CAS latency shows 13; CPU-Z or a similar tool inside the OS will report the same figures.

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

The package contains four 4 GB DDR3 240-pin UDIMM modules for a total of 16 GB; no cables, brackets or additional parts are included or needed for installation.

Which capacity or speed version should I choose for a dual-channel workstation?

This 16 GB kit (4 × 4 GB) at 1866 MHz CL13 1.5 V ECC unbuffered is the only version listed; select it when your board supports DDR3 ECC UDIMMs and you want 16 GB in a dual-channel configuration.
