HPE 809080-091 8GB DDR4-2400MHZ Memory

HPE 809080-091 8GB DDR4-2400 Registered Memory (1Rx8 PC4-2400T-R)

The HPE 809080-091 is an 8GB DDR4 registered DIMM for HPE ProLiant Gen9 servers fitted with Xeon E5-2600 v4 processors. It is a single rank x8 module, labelled PC4-2400T-R, running at DDR4-2400 (PC4-19200) with CAS latency 17, ECC and 1.2V operation.

An 8GB single rank module is the entry point of the Gen9 memory range. It suits servers that need balanced channels without a large total, such as infrastructure servers, small database hosts and branch office systems. The 809080-091 number is the HPE assembly code, which is printed on the DIMM label.

Order the 809080-091 from Euroland IT Store in New or Refurbished condition, subject to the stock we hold.

HPE 809080-091 Technical Specifications

What Is The HPE 809080-091?

This is the assembly number for the module sold as option kit 805347-B21 and serviced under spare part 819410-001. When you find 809080-091 on a DIMM in your server, either of the other two numbers will get you the same 8GB single rank RDIMM.

Precision matters here because HPE sold several 8GB DDR4 modules over the Gen9 and Gen10 years, at 2133, 2400 and 2666. They look alike, but speed and processor support differ. The assembly number pins down exactly which one you have.

Single Rank Modules And Memory Bandwidth

A rank is a set of DRAM chips that the controller reads together. A single rank module has one set, which keeps the electrical load low and lets the channel run at full speed even when more DIMMs are added. Dual rank modules allow some interleaving between ranks and can be slightly faster in certain workloads, but single rank parts are simpler to populate.

The x8 in 1Rx8 refers to the width of each DRAM chip. x8 chips are standard for smaller capacity RDIMMs. They give full ECC protection. Some advanced error correction modes are designed around x4 chips, which is one reason mission critical servers often use larger x4 DIMMs instead.

If you plan to mix this module with dual rank RDIMMs in the same server, read the population rules in the user guide first, as they set out where each rank type should sit in a channel.

New HPE 809080-091

Choose New when you want an unused module, for example to build matched sets across several servers. The product page explains the warranty on new stock.

Refurbished HPE 809080-091

A Refurbished 809080-091 is the budget-friendly way to replace a failed DIMM or complete a channel in an existing Gen9 server. The product page shows the refurbished condition and warranty.

Gen9 Compatibility

This module is listed for HPE ProLiant Gen9 servers with Xeon E5-2600 v4 processors, including:

• ProLiant DL360 Gen9 and DL380 Gen9
• ProLiant DL160 Gen9 and DL180 Gen9
• ProLiant ML350 Gen9 and ML150 Gen9
• ProLiant ML110 Gen9
• ProLiant BL460c Gen9

Check the processor generation as well as the server model. HPE lists DDR4-2400 kits for v4 processors, so a Gen9 server still on v3 processors may not support them. Read the label on an existing DIMM before ordering.

Equivalent Numbers And Related Memory

The HPE 805347-B21 option kit and the HPE 819410-001 spare are the same module under different numbers. For more capacity at the same speed, the store also lists the HPE 805349-B21 16GB DDR4-2400 kit, the HPE 809081-081 16GB DDR4-2400 module and the HPE 836220-B21 16GB DDR4-2400 kit. If your server uses older processors, the HPE 726718-B21 8GB DDR4-2133 kit may be the better match.

How To Check This Is The Right Replacement

• The installed DIMM label shows 809080-091, 819410-001, 805347-B21 or 8GB 1Rx8 PC4-2400T-R.
• The server is a Gen9 model with E5-2600 v4 processors.
• All fitted DIMMs are registered (R), with no load reduced (L) modules.
• The slot is in the correct position for the processor that controls it.
• If you are adding memory, you have enough modules to fill channels evenly.

When A Small DIMM Is The Right Choice

Not every server needs huge memory. Domain controllers, print servers and monitoring hosts often run well on modest RAM. In these cases, using several 8GB modules spread across all channels gives better bandwidth than one or two large DIMMs. It also keeps costs down if you later decide to repurpose the server.

Frequently Asked Questions

What is the option kit for the 809080-091?

The option kit is 805347-B21 and the spare is 819410-001, and both match this 8GB 1Rx8 DDR4-2400 registered module.

Is the 809080-091 compatible with Gen9 servers using v3 processors?

HPE lists DDR4-2400 kits like this one for Gen9 servers with E5-2600 v4 processors, so confirm your processor before ordering.

Why would I choose Refurbished over New?

Refurbished costs less and suits repairs and small upgrades, while New is for buyers who require unused parts.

Where can I see the warranty for this DIMM?

Look on the product page, where the cover for a New or a Refurbished single rank module is set out.

Does UK delivery cost extra?

UK mainland delivery is free on orders over £100 + VAT, and the product page gives full delivery information.
