  • Dual-rank 2Rx8 organisation supports efficient data access

8GB DDR2 Kit for Older Desktop Upgrades

This 8GB kit contains four 2GB DDR2 UDIMM modules rated at 800MHz with CL6 latency and 1.8V operation. It targets owners of legacy desktop systems that still use 240-pin DDR2 memory slots and need a straightforward capacity increase.

PC2-6400 Standard Limits Bus Speed to 800MHz

The PC2-6400 designation fixes the maximum data rate at 800MHz, so the modules cannot run faster even if the motherboard supports higher DDR2 speeds. CL6 timing is the specified latency; tighter timings are not guaranteed by the supplied data.

Narrow 240-Pin UDIMM Design Aids Slot Clearance

Each stick uses a 240-pin unbuffered non-ECC layout on a narrow PCB, which helps fit alongside large CPU coolers in tight chassis. The supplier advises cleaning contacts with an eraser and clearing slots with canned air before installation, and notes that compatibility is not universal across all DDR2 platforms.
