About the P06033-B21

P06033-B21 delivers 32GB capacity on a single-rank 1Rx4 DDR4-3200 ECC registered module for HPE ProLiant Gen10 Plus platforms. Built to take full advantage of 3rd Gen Intel Xeon Scalable and AMD EPYC Rome/Milan memory controllers, it combines maximum capacity with minimal bus trace capacitance, ensuring stable 3200 MT/s operation across all populated DIMM sockets.

Compatibility

Validated on HPE ProLiant DL380 Gen10 Plus, DL360 Gen10 Plus, DL385 Gen10 Plus, DL385 Gen10 Plus v2, DL325 Gen10 Plus, DL325 Gen10 Plus v2, DL345 Gen10 Plus, DL365 Gen10 Plus, and Synergy 480 Gen10 Plus systems. Backward compatible with earlier Gen10 models at lower memory clock speeds.

How to identify a genuine unit

Standard height 288-pin DDR4 registered DIMM with Samsung 16Gb DRAM dies. The front white label displays option part number P06033-B21, spare part number P07642-001, and assembly part number P03849-001, accompanied by the genuine HPE security hologram.

Buying used

Inspect the contact edge connector for signs of mechanical insertion wear or oxidation. Confirm via HPE iLO 5 System Information that the module is authenticated as genuine HPE SmartMemory and that the SPD EEPROM indicates valid 3200 MT/s JEDEC and HPE performance profiles.

FAQ

What processors support P06033-B21 at full 3200 MT/s speed?

3rd Generation Intel Xeon Scalable (Ice Lake-SP) processors and AMD EPYC 7002/7003 Series processors support this DIMM at native 3200 MT/s.

Can single-rank 32GB RDIMMs be mixed with dual-rank 32GB RDIMMs?

Mixing single-rank and dual-rank DIMMs within the same server is supported across different channels, but pairing them within the same memory channel can cause speed reductions.
