Four green memory sticks with silver heatspreaders and gold contacts

Simmtec, Inc

Simmtec, Inc 16GB (4 x 4GB) DDR2 667MHz PC2-5300F ECC FB-DIMM 240-pin with heatspreaders

SKU CH-DK9H-FKFJN

16 GB kit of four 4 GB DDR2 FB-DIMM modules at 667 MHz with ECC and heatspreaders

  • Capacity16GB (4 x 4GB)
  • CAS LatencyCL5
  • 16 GB capacity across four modules for high-density server workloads
  • 667 MHz DDR2 speed rating for compatible legacy platforms
  • PC2-5300F fully-buffered ECC design for data-integrity protection
  • CL5 CAS latency for responsive access timing
  • 240-pin FB-DIMM form factor with heatspreaders for thermal management

16 GB DDR2 ECC FB-DIMM kit

This kit provides 16 GB of DDR2 memory in four 4 GB fully buffered DIMMs. Each module runs at 667 MHz with CL5 latency and includes ECC error correction. The 240-pin FB-DIMM form factor is designed for workstations and servers that require registered, buffered memory.

Suited for legacy workstation upgrades

The modules suit owners of older Apple workstations or compatible servers that specifically demand PC2-5300F FB-DIMM memory with heatspreaders. Builders needing standard unbuffered DDR2, higher frequencies, or larger single-module capacities should look elsewhere.

Fits FB-DIMM slots with chipset support

Installation requires a motherboard equipped for fully buffered DDR2 DIMMs and the corresponding memory controller. The included heatspreaders help manage thermals in densely populated slots, freeing the builder from adding aftermarket cooling for these modules.

Questions about this item

Does my motherboard need 240-pin FB-DIMM slots to use this DDR2 memory?

Yes, the kit is built as 240-pin Fully Buffered DIMMs, so the board must provide matching FB-DIMM sockets.

Can I keep my existing DDR2 CL5 modules and add this 16GB kit without timing conflicts?

Both run at CL5 and 667 MHz, so they will operate at the same speed and latency when mixed.

How can I verify the full 16GB is recognised after installing the four 4GB sticks?

The system BIOS or OS memory report should show 16GB total across the four populated slots.
