8GB DDR3 1600MHz Desktop Module

This 8GB DDR3 1600MHz CL11 1.5V DIMM is built for HP desktops that use part numbers such as 655411-581, 688601-001, 689375-001, B1S54AA, B1S54AT, B4U37AA and B4U37AT. It suits owners of those systems who need more memory for everyday multitasking. The module runs at standard DDR3 voltage and uses major-brand chips.

240-Pin Unbuffered Non-ECC Build

The stick follows the 240-pin DDR3 DIMM form factor and is unbuffered non-ECC, so it drops straight into compatible consumer desktop slots. Standard 1.5V operation means no special voltage configuration is required. Quality-assurance testing on each module helps ensure reliable day-to-day operation.

Upgrade From 4GB Or Smaller Kits

Moving from a 4GB or smaller DDR3 kit to this single 8GB module doubles capacity in one slot, which helps when the system slows under multiple browser tabs, office apps or light creative work. The jump is worth it when the motherboard supports 1600MHz CL11 timing and has a free DIMM socket.
