Crucial 2GB Single DDR2 667MHz (PC2-5300) CL5 Unbuffered UDIMM 240-Pin Desktop Memory Module CT25664AA667
Limited Entry-Level Capacity
Validated by C.R. Vinoth Kumar ยท Founder & Senior Editor
8GB of total memory is extremely marginal in 2026. Windows 11 uses 3-4GB at idle, leaving very little headroom for multitasking or gaming. We highly recommend upgrading to at least 16GB, or 32GB to prevent page-file stutters.
