HPE P00918-B21 8GB SDDR4-2933 Memory

HPE P00918-B21 8GB Single Rank x8 DDR4-2933 Registered Smart Memory Kit

HPE P00918-B21 is the option kit number for an 8GB registered DDR4 module rated at 2933 MT/s. It belongs to the HPE SmartMemory range released in 2019 alongside the 2nd Generation Intel Xeon Scalable processors (Cascade Lake) and is used across ProLiant Gen10 rack, tower and blade servers.

At 8GB per DIMM this is the smallest capacity in the HPE DDR4-2933 line. It suits servers that need every memory channel populated for bandwidth without a large total capacity, such as infrastructure hosts, small database servers or nodes that run a fixed application load.

Euroland IT Store lists the P00918-B21 in New and Refurbished condition, subject to stock. Select the option you want on this page to see its current price, condition details and warranty.

• Offered as New or Refurbished, subject to stock

Option, Spare and Assembly Numbers Explained

HPE gives the same 8GB module several numbers depending on how it is supplied. P00918-B21 is the option kit, the number used when the memory is ordered as an upgrade. The HPE service spare for the same module is P06186-001, and the label on the DIMM itself normally carries an assembly number, which spares references list as P03049-091 for this kit.

All three numbers describe an 8GB single rank x8 DDR4-2933 RDIMM. If your server’s parts list or a failed module shows one of the other numbers, the specification is the same, but it is still worth sending us the label details so we can confirm before you order.

What Speed Will It Run At?

The 2933 rating is the module’s maximum. In ProLiant Gen10 servers the memory controller sits in the processor, so the CPU decides the final speed. According to HPE QuickSpecs, many Xeon Gold 6200 and Platinum 8200 models run memory at 2933 MT/s, most Gold 5200 models run it at 2666 MT/s, and Silver and Bronze models are limited to 2400 MT/s. The module simply clocks down to match.

Gen10 servers use six memory channels per processor with up to two DIMMs per channel. HPE does not support mixing RDIMMs with LRDIMMs, so pair this kit only with other registered modules. Where ranks differ on one channel, HPE advises placing the higher rank DIMM in the white slot.

The New option is unused stock. Packaging and warranty terms for this condition are shown when you select it on the product page.

Refurbished P00918-B21 Memory

The Refurbished option is a previously used module offered as a lower cost alternative. Its condition notes and warranty are displayed when you choose Refurbished, so check them before adding it to your basket.

Compatible HPE ProLiant Gen10 Servers

Spares cross-references list the P00918-B21 for Gen10 servers fitted with 2nd Generation Intel Xeon Scalable processors, including:

• HPE ProLiant BL460c Gen10
• HPE ProLiant DL160 Gen10 and DL180 Gen10
• HPE ProLiant DL360 Gen10 and DL380 Gen10
• HPE ProLiant DL560 Gen10 and DL580 Gen10
• HPE ProLiant ML110 Gen10 and ML350 Gen10

If your server still runs first generation Xeon Scalable processors, check its QuickSpecs before ordering 2933 memory.

How To Confirm This Is The Right Module

• Read the DIMM label: it should show 8GB 1Rx8 PC4-2933Y-R.
• Look for P00918-B21, P06186-001 or P03049-091 on the label or in your parts list.
• Check that your server is a ProLiant Gen10 model with 2nd Gen Xeon Scalable processors.
• Make sure the rest of the installed memory is registered (RDIMM), not LRDIMM.

Frequently Asked Questions

Will the HPE P00918-B21 always run at 2933 MT/s?

No. The processor sets the memory speed. Some Xeon Gold 6200 and Platinum 8200 models run it at 2933 MT/s, while most Gold 5200 models run at 2666 MT/s and Silver or Bronze models at 2400 MT/s.

Is P06186-001 the same memory as P00918-B21?

Yes. P06186-001 is the HPE spare number for the same 8GB single rank x8 DDR4-2933 registered module. P00918-B21 is the option kit number.

Can I install this 8GB kit next to LRDIMMs in my Gen10 server?

No. HPE does not support mixing registered and load reduced DIMMs in the same server, so use it only with other RDIMMs.

How can I tell the New and Refurbished options apart?

New is unused stock, while Refurbished is a previously used module. The condition notes and warranty for each are shown when you select the option on the product page.
