HPE P03053-7A1 64GB DDR4-2933Y Memory

HPE P03053-7A1 64GB DDR4-2933Y Registered Memory Module

The HPE P03053-7A1 is a 64GB DDR4 registered DIMM for ProLiant Gen10 servers. The number is an assembly code, the identifier HPE prints on the module itself, and it appears in spares references as one of two assemblies for option kit P00930-B21 and service spare P06192-001. The other assembly is P03053-0A1.

This -7A1 version follows the same 64GB 2Rx4 PC4-2933Y-R specification, so it is a direct match when a DIMM with this label needs replacing or when you are adding identical modules to an existing bank.

Both New and Refurbished units are listed here, subject to stock. Selecting either option shows its warranty and condition information.

Key Features At A Glance

• 64GB capacity on a single registered DIMM
• Assembly variant listed under HPE option P00930-B21
• Dual rank x4, rated DDR4-2933Y
• ECC protection for server workloads
• Recognised as HPE SmartMemory by Gen10 firmware
• New and Refurbished options, subject to stock

Telling The 64GB Gen10 Modules Apart

Two kinds of 64GB DDR4-2933 module circulate for Gen10 servers, and the label suffix is the quickest way to separate them:

• 2Rx4 PC4-2933Y-R: registered, option P00930-B21, spare P06192-001, assemblies P03053-7A1 and P03053-0A1
• 4Rx4 PC4-2933Y-L: load reduced, option P00926-B21, spare P06190-001, assembly P03054-091

The final letter matters. R means registered and L means load reduced, and HPE does not allow the two types in the same server. The P03053-7A1 is the registered kind, so it belongs in systems that already use RDIMMs.

Capacity Planning With 64GB DIMMs

A Gen10 Xeon Scalable processor has six memory channels and two slots per channel, giving twelve slots per processor. Filled with 64GB modules, that is 768GB per processor, and HPE QuickSpecs for the DL380 Gen10 confirm 24 x 64GB RDIMMs at 2933 MT/s in a two processor system.

Speed depends on the processor model. HPE lists 2933 MT/s for Xeon Platinum 8200 and many Gold 6200 processors, 2666 MT/s for most Gold 5200 processors and 2400 MT/s for Silver and Bronze. HPE also notes that its 64GB 2Rx4 RDIMM on 16Gb DRAM can use up to 62% less memory power than a 64GB 4Rx4 LRDIMM on 8Gb DRAM.

Adding To An Existing Bank

When you extend memory rather than replace it, keep the layout symmetrical. In a two processor server, give each processor the same number and type of modules so both have equal bandwidth and capacity. Each channel accepts up to two registered DIMMs, and where ranks differ on a channel HPE recommends placing the module with more ranks in the white slot. Your server’s documentation shows the slot fill order for each DIMM count.

New P03053-7A1 Memory

The New choice covers unused modules. See the product page for the warranty that applies once selected.

Refurbished P03053-7A1 Memory

Refurbished modules come from previous use and cost less than new. Their condition and warranty details are shown when you choose this option.

Parts That Go With It

• The sister assembly is the HPE P03053-0A1 64GB registered module.
• Order by service number with the HPE P06192-001 64GB spare.
• Servers using load reduced memory need the HPE P06190-001 64GB LRDIMM spare instead.
• For a smaller registered module, see the refurbished HPE P00924-B21 32GB kit.
• Adding a second processor? Pick up the DL380 Gen10 heatsink kit 826706-B21.
• Browse more server heatsinks.
• Explore our wider HPE parts catalogue.

Quick Identification Checklist

• Label text reads 64GB 2Rx4 PC4-2933Y-R.
• Assembly code ends in -7A1 (or -0A1 for the sister version).
• The server is a Gen10 ProLiant, not Gen10 Plus.
• No LRDIMMs (label ending in -L) are installed.

Frequently Asked Questions

Are P03053-7A1 and P03053-0A1 interchangeable?

Spares references list both as assemblies of the same HPE option, P00930-B21, with an identical 64GB 2Rx4 DDR4-2933 registered specification. Contact us with your label details if you need confirmation for a specific server.

My old module label ends in 2933Y-L. Is this the right replacement?

No. A label ending in L is a load reduced DIMM, such as the 64GB P00926-B21 family. The P03053-7A1 is registered, and HPE does not support mixing the two types.

Can I fit this memory in a Gen10 Plus server?

It is listed for Gen10 servers with 2nd Gen Xeon Scalable processors. Gen10 Plus servers use DDR4-3200 memory kits, so check the QuickSpecs for your model first.

Is there a warranty on refurbished P03053-7A1 modules?

The warranty for the Refurbished option, and for New, is shown on the product page when you select that condition.
