SKU CH-3JMD-0T0KZ

8GB DDR2 667MHz FBDIMM ECC memory with 240-pin form factor for compatible systems

  • Total capacity8 GB
  • 8 GB capacity for large workloads
  • DDR2 667 MHz speed for responsive data access
  • Fully-buffered DIMM design for signal integrity
  • 240-pin layout fits compatible desktop slots
  • ECC support detects and corrects memory errors

8GB DDR2 FBDIMM ECC Module

This Samsung M395T1K66AZ4-CE66 is an 8GB DDR2 667 FBDIMM designed for desktop systems that accept fully buffered DIMMs. It operates with ECC error correction and uses the 240-pin form factor required by compatible motherboards. The module is supplied new and intended as a direct replacement or upgrade for supported platforms.

ECC FBDIMM for DDR2 Systems

This memory suits servers or workstations that specifically require registered ECC FBDIMMs running at 667 MT/s. Builders needing standard unbuffered non-ECC UDIMMs or systems that do not support the FBDIMM interface cannot use this part.

240-Pin FBDIMM Form Factor

The 240-pin FBDIMM form factor is the single specification that determines compatibility; only motherboards designed for DDR2 fully buffered DIMMs with ECC support will accept this module.

Questions about this item

What motherboard slot and chipset do I need to install this 240‑pin FBDIMM?

The module requires a 240‑pin FBDIMM slot on a motherboard that supports DDR2 FB‑DIMM memory; standard DDR2 DIMM slots are not compatible.

Can I run this 667 MT/s ECC module with my existing non‑ECC DDR2 DIMMs?

No, FBDIMM architecture and ECC operation prevent mixing with standard non‑ECC DDR2 DIMMs; all slots must use matching FB‑DIMM modules.

How do I verify the module is detected at the correct speed and ECC mode?

Open the BIOS at startup and confirm the memory page lists an 8 GB FB‑DIMM running at 667 MT/s with ECC enabled.
