Two green DDR2 FBDIMM modules with silver heatspreaders and gold contacts

Simmtec, Inc

Simmtec, Inc 4GB (2GBx2) DDR2 667MHz PC2-5300 CL5 ECC FBDIMM 240-pin desktop RAM

SKU CH-CCDP-W9RWH

4GB DDR2 ECC FBDIMM kit running at 667 MHz with CL5 latency and 1.8 V operation

  • Capacity4GB
  • ECC protection catches data errors in critical workloads
  • Fully buffered design reduces electrical load on the memory controller
  • 667 MHz DDR2 speed delivers 5300 MB/s bandwidth
  • 240-pin FBDIMM form factor fits compatible server and workstation boards
  • 8 V operation with 256 Meg x 72 organisation

Target system and module type

This kit provides 4GB of DDR2 memory as two 2GB modules built to the PC2-5300 standard at 667MHz. It uses fully buffered DIMM technology with ECC, so it only works in motherboards that accept FBDIMM modules and will not fit a standard DDR2 socket.

Included heatspreaders and validation

Each module ships with a heatspreader attached and has been tested before dispatch to reduce the chance of errors or instability caused by untested components. The kit runs at 1.8V with a CL5 latency and a 256Meg x 72 organisation.

FBDIMM socket constraint

An FBDIMM module cannot be installed in a regular DDR2 slot and a regular DDR2 module cannot be installed in an FBDIMM slot, so the motherboard must explicitly support the fully buffered interface. The 240-pin form factor looks similar but the keying and signalling are different, preventing cross-installation.

Questions sur cet article

Will the ECC fully buffered DIMMs need any periodic maintenance or component replacement?

No user-serviceable parts exist on these modules; the only future action is replacing the kit if a chip fails.

What limit appears first when the 667 MHz CL5 kit runs under sustained load?

The DDR2 667 MHz data rate and CL5 latency set the throughput ceiling before heat or power become factors.

How much noise, heat or power does the 1.8 V FBDIMM pair produce when running all day?

The 1.8 V DDR2 modules run silently with passive heatspreaders; power draw stays within standard DDR2 limits.
