Compatible 8GB DDR4 UDIMM for HP ProDesk

This 8GB DDR4 2666MHz CL19 module is built for HP ProDesk 400 G5 SFF, 400 G5 Tower, 405 G4 SFF, 600 G4 SFF and 600 G4 Tower systems. It uses a 288-pin unbuffered non-ECC design running at 1.2V. The kit provides a straightforward memory upgrade for those supported desktops.

Suitable for listed HP desktops.

Buyers with the exact HP ProDesk models listed can install this DIMM to add 8GB of capacity. Systems that require ECC or registered memory cannot use this module. Laptops and small-form-factor devices needing 260-pin SO-DIMMs are also incompatible. Check your motherboard manual before purchasing.

2666MHz CL19 speed rating

The module operates at DDR4 2666 (PC4-21300) with a CAS latency of 19. It is backward compatible with 2133MHz and 2400MHz bus speeds. This speed rating is the key specification that determines whether the part matches your system's memory controller requirements.

Questions about this item

Will the 288-pin DDR4 module ever need a heat spreader added later?

No heat spreader is included or required; the module runs at the standard 1.2 V JEDEC voltage without one.

What speed ceiling appears first when the memory runs continuously at 2666 MHz?

The CL19 latency at 2666 MHz is the limiting timing; the module does not support higher frequencies.

How much power does the 8 GB stick draw during all-day operation?

At the rated 1.2 V the module consumes only a few watts, producing minimal heat and no audible noise.
