Arktek's 16GB DDR4 compact SO-DIMM module, running at 3200MHz. As a compact SO-DIMM, it installs into a laptop, notebook, mini-PC, or other small-form-factor system with SO-DIMM memory slots rather than a full-size desktop. Matching capacity, speed, and form factor exactly to the target system (and, for a multi-module upgrade, matching modules to each other) is what lets DDR4 memory run reliably at its full rated speed rather than falling back to a slower, auto-negotiated speed or failing to POST altogether. The catalog's "PC-3200" designation is the JEDEC PC-rating shorthand for the DDR4-3200 speed grade. At 16GB in notebook format, this is a genuinely comfortable laptop memory capacity for multitasking, browser-heavy workloads, and everyday productivity on a laptop with an accessible DDR4 SO-DIMM slot. It is stocked as part of Marvel's broader component range for South African PC builders, upgraders, and system integrators who need confirmed compatibility before purchase.
