4GB DDR3 1600 ECC UDIMM

This 4GB DDR3 1600 ECC UDIMM module is built for servers and workstations that require error-correcting memory. It operates at 1600MHz with a CL11 latency and 1.5V standard voltage. The single-rank 1Rx8 design fits 240-pin DIMM slots in compatible HP systems.

Sustained load stability with ECC

Error-correcting code detects and corrects single-bit errors during continuous operation, preventing data corruption in long-running workloads. Unbuffered architecture keeps latency low while maintaining signal integrity at 1600MHz. The 1.5V standard voltage ensures consistent power draw without overclocking headroom.

Direct 240-pin installation

The module installs directly into any 240-pin DDR3 DIMM slot that supports unbuffered ECC memory. No additional configuration is required beyond verifying the system accepts 1Rx8 density at 1600MHz. Mismatched rank or voltage requirements are the typical cause of boot failure.

Questions about this item

How much heat or power draw should I expect from this 1.5 V DDR3 1600 module running continuously?

It operates at the standard DDR3 voltage of 1.5 V, so power draw and heat are typical for a single 4 GB unbuffered ECC DIMM at that speed.

What must my motherboard provide for this 240-pin DDR3 ECC UDIMM to function?

A DDR3 DIMM slot that accepts unbuffered ECC memory and supports 1.5 V operation at 1600 MHz.

Will this CL11 1600 MHz DDR3 ECC stick work alongside slower DDR3 modules I already have?

The system will run all installed DDR3 memory at the speed and timings of the slowest module present.
