OWC 8GB DDR3 1600 CL11 2Rx8 240-pin 1.5V Non-ECC UDIMM 1U6D32R808GB

HP Desktop Memory Upgrade

This OWC module adds 8 GB of DDR3 memory to compatible HP 280 G1, 285 G2, and 6305 Pro systems. It installs in a standard 240-pin UDIMM slot and runs at 1600 MHz with CL11 latency. The single-rank 2Rx8 design operates at the standard 1.5 V without ECC or buffering. It targets owners of these specific desktops who need more capacity for everyday workloads.

Capacity and Headroom

An 8 GB stick doubles the typical 4 GB factory configuration found in many of these units and provides comfortable headroom for multitasking with office suites, web browsers and light creative tools. The DDR3 1600 interface delivers up to 12 800 MB/s of theoretical bandwidth, which is sufficient for the integrated graphics and processors in the listed HP models. Systems already populated to the board’s maximum slot count or running memory-intensive virtual machines will not gain further benefit from this single module.

Upgrade Path and Value

This module replaces an existing 2 GB or 4 GB DDR3 DIMM or fills an empty slot in the supported HP chassis. The jump is worthwhile when the current configuration forces frequent paging to disk or limits the number of concurrent applications. Builders assembling new systems on other platforms, or users needing ECC, registered DIMMs, or speeds beyond DDR3 1600, should look elsewhere because this part is validated only for the named HP desktops.
