1GB DDR2 ECC kit for servers

This 1GB kit contains two 512MB DDR2 667 modules built for server platforms that require ECC fully buffered memory. The 240-pin DIMMs operate at 1.80V with CL5 latency and include heat spreaders. It suits administrators maintaining legacy systems that specify PC2 5300 registered DIMMs.

Sustained load behaviour

Fully buffered architecture moves the memory buffer onto each module, reducing electrical loading on the motherboard during continuous operation. ECC circuitry corrects single-bit errors on the fly, preventing data corruption during long compute runs. The heat spreaders help dissipate the extra power drawn by the buffer chips under steady throughput.

Compatibility checklist

Verify that your server board explicitly supports DDR2 fully buffered DIMMs at 667 MT/s and accepts 240-pin FB-DIMM slots. Confirm the system requires ECC registered memory rather than unbuffered or standard registered modules. Ensure the BIOS can initialise a dual-channel pair of 512MB density sticks.

Questions about this item

How much heat and power will the 1.80 V fully-buffered DDR2 667 kit produce when running all day?

The modules run at the standard DDR2 1.80 V with a heat spreader on each DIMM, so power draw and thermals stay within normal server DDR2 limits during continuous operation.

What must my system already provide for this 240-pin ECC fully-buffered kit to work?

A server motherboard with 240-pin DDR2 slots that support fully-buffered ECC memory at PC2 5300 speed.

Can I keep this CL5 DDR2 667 kit in a server that still uses older DDR2 memory?

All modules must be fully-buffered ECC DDR2 at the same voltage; mixing with unbuffered or registered DDR2 will prevent the system from booting.
