OWC 2U6D41R808GB 8GB DDR4 2666MHz CL19 1.2V 288-Pin UDIMM for HP Pro 300 G6 A 300 G3 A G2 A G3

8GB DDR4 2666MHz UDIMM for HP Pro 300

This OWC module adds 8GB of DDR4 memory to compatible HP Pro 300 G6, A 300 G3, A G2 and A G3 desktops. It runs at 2666MHz with CL19 latency at 1.2V. The 288-pin unbuffered non-ECC design matches the JEDEC PC4-21300 standard for a warranty-safe upgrade. ||

Sustained 2666MHz operation without heat spreader

The module maintains its rated 2666MHz speed under continuous load using standard JEDEC voltage. Without a heat spreader it relies on case airflow, so sustained throughput stays stable in adequately ventilated chassis. Backward compatibility with 2133MHz and 2400MHz systems means it will clock down automatically if the platform requires it. ||

Tool-free DIMM slot installation

Installation is a simple DIY step: power off, open the case, align the notch on the 288-pin edge connector and press until the retention clips click. The single-rank 1Rx8 organisation avoids density conflicts on these HP boards. The only common issue is forgetting to seat both ends evenly, which leaves the module partially inserted and unrecognised by the BIOS.
