HPE 869538-001 16GB DDR4-2400 Memory

HPE 869538-001 16GB Unbuffered ECC DDR4-2400 Spare Module

Need to replace a memory module in a small HPE server? HPE 869538-001 is the service spare for a 16GB dual rank DDR4-2400 ECC UDIMM. It is the spare that corresponds to HPE Standard Memory option kit 862976-B21, and the DIMM is labelled with assembly number 862690-091.

This spare belongs to HPE’s entry level platforms, chiefly the ProLiant ML30 Gen9 and the ProLiant MicroServer Gen10. Both use unbuffered memory, which sets them apart from the registered memory found in most rack mounted ProLiant servers.

The 869538-001 is listed in New and Refurbished condition, subject to stock at Euroland IT Store.

Key Features At A Glance

• HPE spare part for the 16GB 862976-B21 Standard Memory kit
• ECC unbuffered DDR4 rated at 2400 MT/s
• Dual rank, built with x8 memory chips
• Same module as assembly 862690-091
• A direct swap for a failed 16GB UDIMM in supported servers
• New and Refurbished options, subject to stock

Unbuffered vs Registered: Why It Matters

A registered DIMM (RDIMM) has a register chip that buffers address and command signals, which lets larger servers support many modules per channel. An unbuffered DIMM (UDIMM) has no register, so it suits smaller systems with fewer slots. The two are keyed alike and can look identical, yet a server built for one type will not run the other.

On HPE labels the last letter tells you which you have. The 869538-001 is marked PC4-2400T-E, where E means unbuffered with ECC. A registered 16GB module, for example, would end in R. If you are clearing out spares, keep the two types in separate boxes to avoid mix-ups.

Supported Servers at a Glance

Two HPE platforms are documented for this module, each with its own limits:

• ProLiant ML30 Gen9: four slots across two channels, 64GB maximum, memory at 2133 MT/s with E3-1200 v5 processors and 2400 MT/s with E3-1200 v6 processors.
• ProLiant MicroServer Gen10: two slots, 32GB maximum, memory at up to 1600 MT/s with the Opteron X3216 and up to 2400 MT/s with the X3421 or X3418.

Neither server supports registered or load reduced DIMMs, and HPE does not qualify memory from earlier server generations for them.

Swapping a Faulty UDIMM

Shut down the server and remove the power cords before opening the case. Note which slot holds the faulty module, release the clips at each end, lift it out and seat the 869538-001 firmly in the same slot until the clips close. On boot, check that the BIOS or the management interface reports the full memory size.

Make Sure It Matches

• Look for 869538-001, 862690-091 or 862976-B21 on the old module or its packaging.
• Check the label marking is 16GB 2Rx8 PC4-2400T-E.
• Confirm the host is an ML30 Gen9 or MicroServer Gen10.
• Avoid modules ending in R or L, which are not supported in these servers.

Frequently Asked Questions

What is the difference between 869538-001 and 862976-B21?

They refer to the same 16GB DDR4-2400 ECC UDIMM. 862976-B21 is the HPE option kit number and 869538-001 is the spare number used for service replacements.

Can I use 869538-001 in a server that takes registered memory?

No. It is an unbuffered module, marked with an E at the end of its label. Servers designed for registered DIMMs need modules ending in R.

What is the maximum memory with 869538-001 in each supported server?

HPE lists 64GB for the ProLiant ML30 Gen9 using four 16GB UDIMMs, and 32GB for the MicroServer Gen10 using two.

Is there a difference in warranty between New and Refurbished?

Each option shows its own condition and warranty when selected on this page, so please compare them before you order.

Do you ship the 869538-001 to customers in the UK?
