OWC 8GB DDR4 2666MHz CL19 1.2V 288-Pin UDIMM for HP ProDesk 400 G6 600 G5

OWC 8GB DDR4 2666MHz UDIMM

This OWC module adds 8GB of DDR4 memory to compatible HP ProDesk desktops. It fits the 400 G6 SFF, 400 G6 Tower, 600 G5 SFF and 600 G5 Tower models. The unbuffered 288-pin DIMM runs at 1.2V with CL19 latency. It is a straightforward upgrade for office workstations needing more multitasking headroom.

JEDEC DDR4 2666 standard limits

The module operates at the JEDEC DDR4 2666 (PC4-21300) specification with CL19 timing. It will downclock automatically to 2400MHz or 2133MHz if the system memory controller requires a lower speed. The 1.2V voltage and non-ECC unbuffered design follow the standard desktop UDIMM profile. Systems that require ECC or registered memory cannot use this stick.

Upgrading from 4GB or single-channel

Replacing a single 4GB module or adding this stick to an empty slot doubles capacity and enables dual-channel bandwidth when paired with an identical module. The jump is worth it when the current memory limit forces frequent paging or prevents running multiple business applications together. Buyers who need ECC error correction or registered signal buffering for server-class stability should look elsewhere.
