8GB DDR4 2133MHz for HP 280 G2

This 8GB DDR4 module runs at 2133MHz with CL15 latency and 1.2V operation. It is a 288-pin non-ECC UDIMM built specifically for the HP 280 G2 desktop. The 2Rx8 rank configuration fits the platform's memory architecture. OWC tests each unit to meet JEDEC and OEM specifications.

Upgrade from lower capacity or slower DDR4

Adding this module increases total system memory, allowing more applications and larger files to stay resident. The jump is worth it when the current configuration leaves headroom on the motherboard slots and the workload exceeds the existing capacity. It replaces any DDR4 2133MHz UDIMM of smaller size in the same system.

Limits of the DDR4 2133MHz UDIMM standard

The DDR4 2133MHz interface caps transfer rates at the JEDEC base speed, so bandwidth cannot exceed the PC4-17000 rating. Unbuffered non-ECC modules lack error correction, making them unsuitable for workloads that require data integrity guarantees. Voltage is fixed at 1.2V with no provision for higher performance profiles.

Questions about this item

Will the 288-pin DDR4 UDIMM fit the HP 280 G2 desktop memory slots?

Yes, this 8GB module uses the standard 288-pin DDR4 UDIMM form factor at 1.2V and is validated for the HP 280 G2.

What is the correct way to seat the module, and what step do people often miss?

Align the notch with the slot key, press down firmly until both side clips click into place; the step many miss is not pushing hard enough for the clips to latch.

Does the CL15 2133MHz kit require any future maintenance or replacement?

No, the non-ECC unbuffered DRAM has no moving parts or wear items; it runs at 1.2V per JEDEC spec and carries a limited lifetime warranty.
