HPE 628974-081 16GB DDR3 Memory Kit

HPE 628974-081 16GB DDR3 Memory Module (2Rx4 PC3L-10600R RDIMM)

If the sticker on a DIMM inside your ProLiant G7 server reads 628974-081, this is the replacement you are looking for. HPE 628974-081 is the assembly number of a 16GB dual rank registered DDR3 module, rated PC3L-10600R, which runs at DDR3-1333 with CL9 timing and full ECC.

The module is a low voltage design at 1.35V. It is a common sight in DL360 G7 and DL380 G7 servers that were specified with 16GB DIMMs, and in G7 blades built for virtualisation work.

Both New and Refurbished units are offered by Euroland IT Store; please check the product page to see which grade is in stock today.

HPE 628974-081 Technical Specifications

What Is The HPE 628974-081?

An assembly number identifies the physical build of the module. It is usually the code printed on the white label on the DIMM, together with a text string such as 16GB 2Rx4 PC3L-10600R-9. HPE links this assembly to the option kit 627812-B21 and to the spare part 632204-001, so all three describe one product.

This matters because technicians often open a server, read the label and search for that number. Matching the assembly code means the new module will share the same capacity, rank count, voltage and timing as the DIMMs around it.

Reading The Label: 2Rx4 PC3L-10600R-9

Each part of the label tells you something. 2R means two ranks, so the module presents two sets of DRAM chips to the memory controller. x4 is the width of each DRAM chip. PC3L shows DDR3 low voltage. 10600 is the peak transfer rate in MB/s, which equals DDR3-1333. R stands for registered, and 9 is the CAS latency.

Ranks affect how many modules a channel can hold at a given speed. In many G7 servers, filling all three slots on a channel causes the memory to run at a lower speed than 1333. That is a platform rule rather than a fault, and the server user guide sets out the exact speeds for each population.

New HPE 628974-081

Choose a New 628974-081 when you want unused stock, such as for a project that is adding memory to several servers at once, or for spares that must meet a strict purchasing policy. The product page shows the warranty for new items.

Refurbished HPE 628974-081

The Refurbished option is aimed at teams maintaining G7 servers on a tight budget. It works well for one-for-one replacement of a faulty module. Read the product page for the refurbished condition statement and the warranty attached to it.

How To Confirm The Match

1. Power down the server, open the access panel and read an installed DIMM label.
2. Look for 628974-081, or the text 16GB 2Rx4 PC3L-10600R.
3. Confirm the server generation is G7.
4. Check the memory slot layout in the user guide so the new module goes in the right slot for its processor.
5. Keep registered and unbuffered memory apart; never combine them in one server.

Keeping G7 Servers In Service

Many G7 servers still run file shares, test labs and line-of-business applications. A failed DIMM in one of these machines does not mean the server has reached the end of its life. Replacing the single bad module costs far less than a new platform and avoids a migration project. Keep one or two matching spares on hand if you run several identical G7 servers.

Frequently Asked Questions

What does the 628974-081 number mean?

It is the HPE assembly number printed on the module label, and it matches option kit 627812-B21 and spare part 632204-001.

Will the 628974-081 work in my server?

It is compatible with ProLiant G7 servers such as the DL360 G7, DL380 G7 and DL580 G7 and the BL460c G7 and BL620c G7 blades, so confirm your model before you buy.

Which is better for me, New or Refurbished?

New is best for projects that need unused parts, and Refurbished is a cheaper route for replacing a single faulty DIMM in an older server.

Is there a warranty on this module?

Yes, the warranty for the condition you select is shown on the product page.
