4GB DDR3 ECC RDIMM Server Memory

This 4GB DDR3 module operates at 1333 MHz with CL9 latency and 1.5V standard voltage. It uses a registered DIMM design with 2Rx4 organisation and Micron chipset for error-correcting server workloads. The 240-pin form factor fits compatible DDR3 server platforms.

Suits servers needing registered ECC DDR3 at 1333

This module matches systems qualified for Micron MT36JDZS51272PZ-1G4F1AD and related part numbers. It is not for desktop boards that require unbuffered non-ECC memory. Buyers whose platforms demand a different voltage, speed, or rank configuration cannot use this product.

Registered ECC with 2Rx4 organisation decides fit

The 2Rx4 registered ECC layout is the single specification that determines whether a DDR3 server board will accept this module. Verify the motherboard documentation for registered DIMM support and this exact rank structure before purchase.

Questions about this item

How much power does this 1.50 V DDR3 1333 module draw when the server runs continuously?

The module operates at the standard DDR3 voltage of 1.50 V; registered ECC DIMMs at this speed typically draw a few watts per stick under sustained load, so total power scales with the number of modules installed.

What must the motherboard provide for this 240-pin registered ECC DIMM to function?

The board needs DDR3 DIMM slots wired for registered (buffered) memory with ECC support and a memory controller that accepts 2Rx4 organisation at PC3-10600 speed.

Can this PC3-10600 registered ECC stick share a channel with older unbuffered non-ECC DDR3 DIMMs?

No — registered and unbuffered DIMMs cannot be mixed on the same channel, and ECC must be enabled across all populated slots for the module to operate correctly.
