4GB DDR3 1866 ECC UDIMM Server Module

This A-Tech module delivers 4GB of DDR3 1866 memory with ECC error correction for IBM-Lenovo 4X70G00092 compatible servers and workstations. It uses unbuffered 1Rx8 organisation and standard 1.50V operation. System administrators upgrading memory capacity in supported platforms will find this a direct replacement part.

Sustained Load Behaviour with CL13 Timing

The module runs at PC3-14900 speed with CAS latency 13 under continuous server workloads. ECC circuitry detects and corrects single-bit errors throughout extended uptime without buffering overhead. Major brand chips and rigorous testing maintain signal integrity during prolonged multi-tasking or virtualisation duties.

Verify DIMM Slots and Maximum Capacity Before

Confirm your system accepts 240-pin DDR3 UDIMM modules and supports 4GB per slot at 1866 MHz. Check the motherboard or server manual for total memory limit and population rules. This module is not for systems requiring registered DIMMs, different voltage, or non-ECC memory.

Questions about this item

How much heat and power does this 1.50 V DDR3 1866 module add when running continuously?

At 1.50 V standard DDR3 voltage the module draws typical unbuffered DIMM power and produces modest heat; adequate case airflow is sufficient for all-day operation.

What must my system already provide for this 240-pin ECC UDIMM to function?

A DDR3 server or workstation motherboard with an available 240-pin UDIMM slot, ECC support in the BIOS, and memory-controller capability for 1866 MHz CL13 1Rx8 modules.

Will this CL13 1Rx8 module work alongside older CL13 DDR3 1866 DIMMs I already have?

Yes, if the existing DIMMs are also DDR3 1866 CL13 ECC unbuffered 1Rx8, the memory controller will run the combined set at the common 1866 MHz CL13 settings.
