1GB DDR2 667 Desktop Module

This 1GB DDR2 667 (PC2 5300) desktop module runs at CL5 latency on 1.80V. It uses a 240-pin unbuffered layout without a heat spreader. The stick adds a single gigabyte of memory to older desktop platforms.

Suits legacy DDR2 upgrades only

Owners of motherboards that accept DDR2 667 unbuffered DIMMs can use this module to replace a failed stick or fill a vacant slot. Builders who need more capacity per slot, registered memory or a different voltage should look elsewhere.

240-pin DDR2 interface decides fit

The module fits only boards with a 240-pin DDR2 socket that support 667 MT/s unbuffered memory at 1.80V. Checking the motherboard manual for that exact socket and speed rating is the single step that confirms compatibility.

Perguntas sobre este artigo

How do I install the 240-pin DDR2 module, and which alignment step is often missed?

Align the notch on the 240-pin module with the key in the DDR2 slot, press down evenly until both side clips snap shut, and verify the notch is fully seated before applying force.

What maintenance or replacement will this 1GB DDR2 667 stick need over time?

No scheduled maintenance is required; keep the contacts clean and replace the module only if memory errors appear or a larger capacity is needed.

What limit appears first when this CL5 1.80V DDR2 667 memory runs under sustained load?

The DDR2 667 (PC2 5300) bandwidth ceiling is reached before latency or voltage become bottlenecks during continuous operation.
