HPE-Compatible 16 GB DDR4 Server Memory

This 288-pin DDR4 module delivers 16 GB of ECC unbuffered memory at 2666 MHz. It operates at 1.20 V and uses a 2Rx8 rank configuration with major-brand DRAM chips. The part is validated as 100 percent compatible with HPE part number 879527-091.

Fits Standard DDR4 Server Slots

The module installs directly into any 288-pin DDR4 DIMM slot that supports PC4-21300 speeds and 1.2 V operation. ECC capability protects data integrity in multi-socket platforms. Unbuffered design keeps latency low for workloads that do not require registered memory. Matching modules are supplied so channels can be populated identically.

Suited for HPE Server Upgrades

Ideal for administrators extending the life of existing HPE infrastructure with guaranteed compatibility and lifetime warranty coverage. Not suitable for systems that require registered or load-reduced DIMMs, platforms limited to lower DDR4 speeds, or builds needing capacities beyond 16 GB per slot.

Questions about this item

At what point does the 2666 MT/s speed become the bottleneck during sustained workloads?

The DDR4-2666 rating sets the maximum data rate; sustained throughput cannot exceed the 21300 MB/s peak bandwidth of each 16GB module.

How much extra heat or power draw should I expect from the 1.20 V unbuffered DIMMs running continuously?

Each stick operates at 1.20 V with no register circuitry, so power draw and thermal output stay at standard DDR4 levels for 2Rx8 density.

Which specific HPE server part number must my system already use for this memory to work?

The module is validated as a direct replacement for HPE part 879527-091; the server must accept that part number for guaranteed compatibility.
