Compatible 4GB DDR3 Server Module

This 4GB DDR3 1333MHz ECC UDIMM replaces the Crucial CT51272BA1339 part for server and workstation upgrades. It operates at 1.5V standard voltage with CL9 latency and a 2Rx8 rank configuration. The unbuffered design suits platforms that accept non-registered ECC memory. Verify your system specifications before ordering.

DDR3 1333 Interface Limits

The PC3-10600 rating defines the maximum transfer rate for this DDR3 generation. ECC error correction adds reliability for data integrity but reduces usable bandwidth slightly compared to non-ECC equivalents. Unbuffered modules place the full electrical load on the memory controller, limiting the number of DIMMs per channel. The 1333MHz speed caps throughput on faster platforms.

240-Pin UDIMM Build and Fit

The module uses a 240-pin DIMM edge connector standard for DDR3 UDIMM sockets. Major-brand DRAM chips are mounted in a 2Rx8 organisation on a single-sided PCB. Unbuffered construction keeps the profile low for dense server chassis. The 1.5V supply matches standard DDR3 power rails without extra regulation.

Questions about this item

Should I pick the single 4GB module or a larger kit for my server?

The listing is for one 4GB DDR3 1333 ECC UDIMM; add more identical modules to reach your board's supported capacity.

What does the PC3-10600 rating deliver in a live system?

It runs at 1333 MT/s with CL9 latency at 1.5V, giving standard DDR3 bandwidth for compatible servers.

Does the 240-pin DDR3 interface limit speed or capacity on my motherboard?

The 240-pin DDR3 slot caps at DDR3 1333; your board's chipset and BIOS determine the maximum total memory.
