Product Identity

This Samsung DDR3 module delivers 8 GB of registered ECC memory for server platforms that require the 240-pin form factor and PC3-12800 speed rating. It operates at 1.35 V with CL11 latency and a 2Rx4 rank configuration.

Fit and Limits

The module suits administrators upgrading or repairing DDR3-era rackmount or tower servers that accept registered DIMMs and need error correction. Builders assembling consumer desktops, laptops or workstations that use unbuffered memory should look elsewhere.

Deciding Specification

The registered ECC design combined with DDR3 1600 signalling is the single attribute that determines compatibility; only systems explicitly qualified for registered DDR3 DIMMs can use this part.

Highlights

  • 8GB capacity supports larger server workloads
  • DDR3 1600 speed delivers 12800 MB/s bandwidth
  • ECC Registered design corrects data errors automatically
  • CL11 latency keeps response times tight
  • 35V operation reduces power draw per module

Questions about this item

Does my motherboard need 240-pin DDR3 slots to use this 8GB module?

Yes, this module is a 240-pin DDR3 SDRAM DIMM and requires a motherboard with matching DDR3 slots that support ECC registered memory.

Can I mix this CL11 registered ECC stick with older unbuffered DDR3 DIMMs in the same server?

No, registered and unbuffered modules cannot be mixed on the same channel; all slots must use registered ECC DIMMs for the system to operate correctly.

How do I confirm the module is running at DDR3 1600 with CL11 timings after installation?

Check the BIOS memory information or use a tool like CPU-Z to verify the speed reads 1600 MT/s (PC3-12800) and the CAS latency shows CL11 at 1.35V.
