HPE 684034-001 4GB DDR3-1600 Memory Kit

HPE 684034-001 4GB PC3-12800E DDR3-1600 Spare Memory Module

Service engineers and small business IT staff will know HPE 684034-001 as the spare part code for a 4GB unbuffered DDR3 DIMM. It is the module HPE uses to replace a failed 4GB stick in compact ProLiant Gen8 servers.

The specification is simple: one 4GB dual rank x8 UDIMM, PC3-12800E, so DDR3-1600 with ECC, CAS latency 11 and 1.5V operation. It does not carry a register, which is what entry-level single processor Gen8 servers expect.

At Euroland IT Store this spare is sold as New or Refurbished; the grades available change with stock.

HPE 684034-001 Technical Specifications

What Is The HPE 684034-001?

HPE spare numbers end in -001 or similar and are used by the HPE service organisation. This one maps to the 669322-B21 option kit, which is the retail upgrade, and to assembly number 669238-071, which is the code on the module sticker. All three describe the same 4GB unbuffered ECC DIMM.

When a server reports a memory fault, the service documentation will list the spare number rather than the option. Ordering 684034-001 keeps the replacement aligned with what HPE expects in that slot.

Decoding PC3-12800E

PC3 means DDR3 memory. 12800 is the peak bandwidth in megabytes per second, which corresponds to 1600 million transfers per second, or DDR3-1600. The final letter E means unbuffered with ECC. By contrast, an R would mean registered, and a module with no letter at all would usually be desktop memory without ECC.

Because the label carries no L after PC3, this module is a standard 1.5V part, not a low voltage one. If your server already holds PC3L modules, the system will usually run the whole set at a voltage and speed that every module supports.

Diagnosing A Memory Fault In A Gen8 Entry Server

Small Gen8 servers have only a handful of slots, so one bad module can halve the usable memory or stop the server booting. Check the iLO event log or the Integrated Management Log first; it records the slot number of correctable and uncorrectable errors. Swap the reported module with a known good 684034-001. If the error follows the old module to another slot, the DIMM was at fault. If it stays with the slot, look at the system board.

New HPE 684034-001

New spares are ideal for organisations that keep a stock of unused parts for planned maintenance. Details of the warranty on new units are given on the product page.

Refurbished HPE 684034-001

A Refurbished 684034-001 helps keep an older MicroServer or ML310e running without spending much. It is a good match for one-off replacements. Refurbished condition notes and warranty information are on the product page.

Which Servers Take This Module?

• HPE ProLiant MicroServer Gen8
• HPE ProLiant ML310e Gen8 v2

These are the platforms we could confirm. Other Gen8 systems that use unbuffered ECC memory may also accept it, but please check the label on an existing DIMM and the server model before ordering rather than relying on a general list.

Linked Part Numbers

Option kit 669322-B21 and assembly code 669238-071 describe this same module. The HPE 669238-071 listing is useful if your existing DIMM shows the assembly code. Other DDR3-1600 items in the catalogue include the HPE 647895-B21 4GB DDR3-1600 kit, the HPE 647873-B21 4GB DDR3-1600 kit and the HPE 647899-B21 8GB DDR3-1600 kit, while the HPE 500656-B21 2GB DDR3-1333 kit is a smaller module. Check whether each one is unbuffered or registered before choosing it for a Gen8 entry server.

Pre-Order Checks

1. Find the sticker on an existing DIMM and compare it with 684034-001, 669322-B21, 669238-071 or 4GB 2Rx8 PC3-12800E.
2. Confirm the server model name, including any v2 suffix.
3. Look for the E suffix on the speed code, which confirms unbuffered ECC.
4. Note the total memory your server supports so the upgrade stays within it.
5. Record the slot reported in the event log if you are replacing a failed module.
