Arktek's 4GB DDR3 standard desktop DIMM module, running at 1600MHz. As a standard desktop DIMM, it installs into any DDR-generation-matching desktop or small-form-factor PC motherboard. 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 DDR3 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-1600" designation is the JEDEC PC-rating shorthand for the DDR3-1600 speed grade. At 4GB, this is a basic capacity aimed at reviving or lightly upgrading an older DDR3-platform desktop PC for basic office and everyday computing use, rather than any memory-intensive modern workload. 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.
