Crucial Ballistix Sport 4GB Single DDR3 1333 MT/s (PC3-10600) CL9 @1.5V UDIMM 240-Pin Memory BLS4G3D1339DS1S00
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.
