SK hynix HMT351U6CFR8C-H9 4 GB DDR3-1600 desktop RAM

4 GB DDR3-1600 desktop module

This 4 GB DDR3-1600 DIMM adds memory capacity to desktop systems that use 240-pin slots. It suits office PCs and older workstations needing a straightforward capacity increase. The single-module design keeps upgrades simple when free slots are limited. It is not for buyers who need higher total capacities or faster data rates than DDR3 provides.

Tool-free slot installation

Align the notch on the 240-pin edge connector with the motherboard key and press down until the retention clips click. The UDIMM form factor fits standard desktop DIMM sockets without adapters. Problems usually arise when the board only supports lower bus speeds such as 1333 MHz, causing the module to downclock. It is not for builders who need registered or ECC memory for server platforms.

Steady operation at rated speed

The module runs at PC3-12800 with CL9 latency under continuous workloads typical of office applications and light multitasking. DDR3 SDRAM technology maintains stable throughput without the thermal throttling seen in higher-density kits. Sustained performance matches the JEDEC specification for the rated frequency. It is not for users who require overclocking headroom or extreme bandwidth for rendering farms.
