A-Tech 4GB DDR3L ECC RDIMM

This 4GB registered DDR3L module runs at 1333MHz with CL9 latency and 1.35V operation. It uses a 1Rx4 organisation and major-brand chips for server-grade reliability. The stick is built as a direct replacement for numerous HP part numbers including 604500-B21 and 606426-001.

DDR3L 1333 registered DIMM limits

Registered DIMMs require a motherboard that supports registered memory; they will not work in standard desktop boards that expect unbuffered modules. The DDR3L 1.35V specification is backward compatible with 1.5V DDR3 slots, but the system must accept ECC RDIMMs to use the error-correction and registration features.

Check your server before ordering

Verify that your system lists the HP part numbers above or explicitly supports DDR3L 1333MHz ECC RDIMM 1Rx4 modules. Confirm the motherboard has 240-pin DIMM slots and accepts registered memory, as consumer platforms typically do not. Matching the exact rank and voltage avoids boot failures.

Questions about this item

Is this a single 4GB module or a kit of multiple sticks?

This listing is for one 4GB DDR3L module running at 1333MHz with CL9 latency and 1.35V operation.

Will the registered ECC design slow down my workstation compared to standard unbuffered memory?

The registered buffer adds one clock cycle of latency, but it allows the memory controller to drive more modules reliably at 1333MHz without signal degradation.

My motherboard has 240-pin DDR3 slots — does the DDR3L 1.35V spec limit the speed I will actually see?

The module is rated for PC3L-10600 at 1333MHz; it will run at that speed provided the platform supports DDR3L voltage and registered DIMMs.
