Four green FB-DIMM modules with silver heatspreaders

Simmtec, Inc

Simmtec, Inc 8GB (4 x 2GB) DDR2 667MHz PC2-5300 ECC FB-DIMM

SKU CH-26FZ-V02CC

ECC fully-buffered DDR2 kit with four 2 GB modules running at 667 MHz PC2-5300 on 240-pin FB-DIMMs

  • Total capacity8 GB (4 × 2 GB)
  • ECC protection prevents data corruption in critical workloads
  • Fully buffered architecture improves signal integrity on 240-pin modules
  • 667 MHz DDR2 speed delivers PC2-5300 bandwidth for compatible servers
  • Dual-rank 2Rx8 organisation increases memory density per channel
  • Integrated heatspreaders help maintain stable temperatures during operation

ECC Fully Buffered DIMM

This kit provides 8 GB of DDR2 memory as four 2 GB modules. The modules use a 240 pin FB-DIMM form factor with ECC and fully buffered signalling. They run at 667 MHz, rated PC2-5300F.

Compatibility constraint

An FB-DIMM will not fit into a standard DDR2 socket and a standard DDR2 module will not fit into an FB-DIMM socket. Buyers whose systems require standard unbuffered DDR2 must choose a different module type.

Speed and density

The decisive specification is the 667 MHz PC2-5300F rating on a 240 pin FB-DIMM with ECC. Verify the motherboard documentation calls for this exact combination before ordering.

Questions about this item

Will the 240-pin FB-DIMM modules work in my older motherboard that uses standard DDR2 slots?

No, an FB-DIMM will not fit into a standard DDR2 socket because the key notch is in a different position.

How can I verify the kit is running at the rated 667MHz PC2-5300 speed after installation?

Check the memory frequency in the BIOS or a system-information utility; it should report 667MHz for each module.

Does the package include the four 2GB modules with heatspreaders already attached, or must I buy cooling separately?

The kit includes four 2GB FB-DIMM modules with heatspreaders pre-installed; no extra cooling is required.
