Kit details

This kit supplies two 1 GB DDR2 modules for a total of 2 GB. It is built for servers and workstations that require ECC unbuffered memory running at 667 MHz. Each stick uses a 240-pin layout and operates at 1.80 V with CL5 latency. Buyers needing higher capacities or registered DIMMs should look elsewhere.

Installation notes

The modules slot into standard 240-pin DDR2 sockets and are keyed to prevent incorrect insertion. No heat spreader is fitted, so clearance inside dense chassis is rarely an issue. Common problems include mixing these unbuffered sticks with registered memory or populating slots in an order the board firmware does not support.

Compatibility checks

Verify that your system accepts DDR2 667 (PC2 5300) ECC unbuffered DIMMs before ordering. Confirm the motherboard or server manual lists this exact speed, voltage and error-correction type. Ensure the platform can address 1 GB per module and that the memory controller supports dual-channel operation with this kit.

Questions about this item

How can I verify the kit is running at DDR2 667 with CL5 after installation?

Check the BIOS memory information or a system utility such as CPU-Z; it should report 667 MHz, PC2-5300 and CL5 timings at 1.80 V.

What is included in the box and what must be purchased separately?

The box contains two 1 GB 240-pin DDR2 SDRAM modules; no heat spreaders, cables or additional components are included.

Should I choose this 2 GB dual-channel kit or a different capacity for my server?

This kit provides 2 GB total in a matched pair for dual-channel operation; select it if your board supports DDR2 667 ECC unbuffered memory and 2 GB meets your workload needs.
