Server-grade DDR3 module

This 4 GB registered DIMM uses ECC to detect and correct single-bit errors, a requirement for most server and workstation boards. The 240-pin DDR3 form factor fits compatible enterprise platforms. It is not for consumer desktops or laptops that lack registered-memory support.

Registered ECC requirement

The module is registered and ECC-enabled; the system chipset and BIOS must explicitly support both features or the DIMM will not function. Standard unbuffered consumer boards cannot use it. Builders who need unbuffered non-ECC memory should select a different part.

Low-voltage DDR3 operation

DDR3 1600 at CL11 runs at the standard 1.35 V for this speed grade, keeping power draw modest in multi-DIMM configurations. Passive cooling in a server chassis with directed airflow is sufficient; no active heatsink or additional fan is required.

Questions about this item

What does DDR3 1600 (PC3 12800) mean for actual server throughput?

The module runs at 1600 MT/s, giving a peak bandwidth of 12800 MB/s per stick when the platform supports that data rate.

How does the 240-pin registered ECC interface limit usable speed?

The registered buffer adds one clock cycle of latency, and the system memory controller caps the final operating frequency to the lowest rated module or CPU limit.

Will this 240-pin DDR3 stick fit my server's DIMM slots?

It requires a standard 240-pin DDR3 DIMM slot with registered/ECC support; the physical key notch matches DDR3 sockets only.
