8 GB DDR3-1333 ECC Registered Server Memory

This SK hynix module delivers 8 GB of DDR3 SDRAM at 1333 MT/s with a CL9 latency and 1.50 V operation. It uses a 240-pin form factor and features ECC with registered buffering in a 2Rx4 organisation. The part is new and intended for server platforms that require registered ECC memory.

Suited for servers needing registered ECC DDR3

It fits systems that specifically call for PC3-10600 registered modules with ECC error correction. It is not for desktops or workstations that only accept unbuffered non-ECC memory, nor for platforms that require a different DDR generation, voltage, speed grade, or module density.

Registered ECC with 2Rx4 organisation

The registered buffer and ECC function together with the 2Rx4 rank structure to provide the signal integrity and error detection required by compatible server chipsets. Verify that your motherboard supports registered ECC DDR3 at this speed and voltage before purchase.

Questions about this item

What does the DDR3 1333 (PC3 10600) speed rating mean for actual server throughput?

The module transfers data at 1333 MT/s with CL9 timing, providing 10600 MB/s peak bandwidth per stick when the platform runs the memory at its rated frequency.

How does the 240-pin DDR3 registered ECC interface affect compatibility and error handling?

The 240-pin registered DDR3 design adds a buffer that reduces electrical load on the memory controller, while ECC circuitry detects and corrects single-bit errors for data integrity.

What physical space and slot requirements does this 8 GB module need?

It occupies one standard 240-pin DDR3 DIMM slot and requires a server motherboard that supports registered ECC memory at 1.5 V.
