Questions about this item

How do I install the four 240-pin DDR2 modules and what step do people often miss?

Power off the PC, open the case, align each module’s notch with the slot key, press down firmly until both retention clips click, then verify all four sticks are recognised in BIOS.

What maintenance or replacement will this 800 MHz DDR2 kit need over time?

Dust the slots and contacts occasionally; if errors appear, test each 1 GB stick individually and replace any faulty module with a matching DDR2 PC2-6400U part.
