Kit Composition

This NEMIX RAM kit provides 8 GB of desktop memory across four 2 GB modules. It uses the DDR2 800 standard, also labelled PC2-6400, with a CAS latency of CL6 and a default voltage of 1.8 V. The sticks are 240-pin unbuffered UDIMMs without ECC or heat spreaders.

Target Systems

The kit suits older desktop motherboards that accept DDR2 UDIMMs and can run at 800 MHz with 1.8 V operation. Builders repairing or upgrading legacy workstations or basic office PCs will find it a direct match. Systems that require registered or ECC memory, or boards limited to slower DDR2 speeds, should look elsewhere.

Deciding Specification

The decisive figure is the DDR2 800 (PC2-6400) speed rating combined with CL6 timing at 1.8 V. If the motherboard specifies this exact speed and voltage the kit will slot in and run at its rated settings without further adjustment.

Questions about this item

Will these 240-pin DDR2 UDIMM modules fit my motherboard's DDR2 slots?

The kit uses the standard 240-pin DDR2 UDIMM form factor, so it fits any desktop board with DDR2 DIMM slots.

What is the correct way to seat the four 2GB sticks, and what step do people often miss?

Open the retention clips, align the notch on each module with the slot key, press down firmly until both clips snap shut, then verify all four are fully latched.

How long will these DDR2 800 modules last before they need replacement?

DDR2 memory has no moving parts and no wear cycle; it typically runs for the life of the system unless physically damaged or a voltage fault occurs.
