8GB handles basic office tasks โ may slow with many tabs open
8GB is insufficient for video editing or 3D rendering workloads
SO-DIMM laptop RAM is not used in servers โ servers require DIMM or RDIMM modules
SO-DIMM form factor โ correct type for laptop memory upgrades. Verify your laptop has an accessible slot.

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.
