Frequently Asked Questions

What does the -091 suffix indicate on P12980-091?

The -091 suffix denotes a regional or OEM configuration variant of the P12980 part number family. The core hardware specifications — 16GB DDR4-2933 ECC Registered CL21 1.2V Dual Rank x8 288-pin DIMM — are consistent across the P12980 family. Verify compatibility with your specific HPE ProLiant Gen10/Gen10 Plus configuration via HPE QuickSpecs.

What is the maximum DDR4 speed supported by Gen10 and Gen10 Plus?

HPE ProLiant Gen10 platforms based on Intel Cascade Lake support DDR4-2933 as the maximum validated RDIMM speed. Gen10 Plus platforms based on Intel Cooper Lake or AMD EPYC may support DDR4-3200 depending on CPU and memory channel configuration. P12980-091 at DDR4-2933 is compatible with both Gen10 and Gen10 Plus platforms at the 2933MHz validated speed.

Can P12980-091 be mixed with other 16GB DDR4-2933 RDIMMs in the same server?

HPE recommends populating memory channels with identical part numbers for optimal performance and validated operation. Mixing part numbers within the same channel may result in the memory running at the lowest common denominator speed or may affect stability. For reliable enterprise operation, use the same P12980-091 part number across all populated DIMM slots in a memory channel.

The HPE P12980-091 16GB DDR4-2933 ECC Registered CL21 1.2V Dual Rank x8 RDIMM delivers validated DDR4 server memory for HPE ProLiant Gen10 and Gen10 Plus. Order today — in stock at the best price.
