Two green DDR2 DIMM sticks with black chips and gold contacts

Simmtec, Inc

Simmtec, Inc 4GB Kit 2x2GB DDR2-667 DIMM

SKU CH-KPX6-5NRFA

Provides 4 GB of DDR2 desktop memory in a dual-channel kit of two 240-pin DIMMs running at 667 MHz with CL5 latency

  • Capacity4GB (2 x 2GB)
  • 4GB total capacity with two matched 2GB modules
  • 667 MHz DDR2 speed rated at PC2-5300
  • Low CL5 latency for responsive desktop performance
  • Standard 1.8 V operation keeps power draw modest
  • 240-pin unbuffered non-ECC DIMMs fit typical desktop slots

DDR2-667 desktop memory kit

This 4 GB kit contains two 2 GB unbuffered DIMMs built to the DDR2-667 standard. Each module carries 16 chips in a 128 x 8 arrangement and operates at 1.8 V. The kit suits older desktop platforms that require PC2-5300 memory.

Sustained-load behaviour

The modules run at CL5 latency with a dual-rank 2Rx8 organisation across 240 pins. Under continuous use the standard 1.8 V supply and normal-height profile keep thermals predictable. No ECC or registered circuitry is present, so data integrity relies on the host controller.

PC2-5300 interface limits

The DDR2-667 bus tops out at the 5300 MT/s transfer rate defined by the PC2-5300 designation. Systems that demand higher bandwidth, ECC protection or registered signalling cannot use this kit. Builders needing larger capacities or faster speeds must select a different memory standard.

Questions about this item

How much heat does the 1.8V DDR2 kit produce during sustained use?

The modules run at 1.8 volts, a standard DDR2 voltage that keeps power draw and heat output low during continuous operation.

What motherboard slot and memory type must my system already have to use this kit?

Your board needs four 240-pin DDR2 DIMM slots and must support PC2-5300 DDR2-667 unbuffered non-ECC memory.

Will this CL5 dual-rank kit run stably alongside older CL6 single-rank DDR2 sticks?

The motherboard will clock all installed modules to the slowest speed and loosest timings, so mixing ranks and CAS latencies is possible but not guaranteed stable.
