Non-contractual photos

The visuals on this page are supplied by the manufacturer. They are frequently produced for a whole range — not for the exact model you are viewing: what you see in the photo is never a promise of what is included.

No exchange, return or cancellation will be accepted on the grounds that something seen in a photo (accessory, port, colour, keyboard layout, packaging…) is not found on the delivered product. Only the specifications written on the page are binding for the order.

What the image does not guarantee:

  • Design and revisions : one component is produced by several partner manufacturers: cooler, backplate, RGB lighting and printing change with the version delivered.
  • Quantity : an image showing two memory modules or several fans does not mean the set is sold that way — check the packaging in the specifications.
  • Cooling : a processor may be sold without a cooler, and not all the fans visible inside a case are supplied.
  • Accessories : cables, adapters, screws, brackets and software licences are supplied only if the specifications say so.
  • Colour : one image often serves several colours, and the shade you see depends on studio lighting as much as on your screen settings; the colour sold is the one in the title and the specifications.
  • Props and accessories : the items shown around the product (cables, stands, decorative objects, content displayed on screen) are not included unless explicitly stated.
  • Packaging : boxes, labels and bundles change with the manufacturer's revisions: the packaging delivered may differ from the one in the photo.

What is binding: the product title, this page's technical specifications, the description and, when provided, the manufacturer's PDF datasheet available in the downloads.

The slightest doubt about a specification? Contact us before ordering and we will check for you.

1 year warranty — free repair in Morocco if it breaks down during the warranty period

1 year manufacturer's warranty

This product is covered for 1 year by a manufacturer's warranty (the brand's official warranty). Your iris.ma invoice serves as the warranty document: keep it safe.

A problem with your product? Don't worry: contact us by phone, WhatsApp or e-mail. Depending on the brand, we direct you either straight to the repairer appointed by the brand to fix your product, or to us — and we take care of the rest.

  • If a repair is possible, it is carried out free of charge.
  • If the product cannot be repaired, the brand offers an exchange for another product.
  • If no product is available, a refund is issued as soon as the brand confirms it.

Faulty straight out of the box? Some brands offer an immediate exchange, others a repair. Contact us to find out what applies to your product.

The warranty covers breakdowns occurring under normal use, as defined by the brand's terms. Product breakage (drop, impact, liquid…) is not covered, nor are certain consumable parts.

Frequently asked questions about this product

Which servers is this HPE 879505-B21 memory intended for?
HPE ProLiant Gen9, Gen10 and Gen10 Plus servers, as well as the Apollo, Synergy and Blade ranges. Check your model's compatibility list before ordering.
What is the difference between this UDIMM and an RDIMM module?
This one is unbuffered: there is no intermediate register between the chips and the controller, unlike registered RDIMM modules. The server expects one or the other — the two are not interchangeable.
What workloads is this memory intended for?
Cloud computing, virtualisation and databases — the uses where the number of virtual machines or the size of the dataset, more than the frequency, determines what the server can handle.
Does this HPE kit contain one module or several?
A single 8 GB module, despite the name “kit”. The server's other slots remain free for adding more later.
Will this DDR4 module fit in a DDR5 slot?
No: the two generations do not have the same connector. On a ProLiant Gen9 or Gen10, DDR4 is indeed what you need.
Why choose HPE memory rather than a third-party module?
Because it is built from top-quality DRAM and subjected to a rigorous testing and authentication process, which ensures it is optimised for HPE platforms. The manufacturer explicitly contrasts this control with third-party alternatives.
What is the latency of this HPE 8 GB module?
CAS 19-19-19 at 2,666 MHz, single rank x8. These are the reference timings for server DDR4-2666, chosen for stability rather than peak speed.
Is this HPE 8 GB memory kit new and under warranty?
Yes, it is a new HPE product, reference 879505-B21. The invoice serves as the warranty document, for 1 year. Keep it in case a defect is found.
