Frequently Asked Questions

What does the -0A1 suffix indicate on P43333-0A1?

The -0A1 suffix denotes a regional or OEM configuration variant of the P43333 part number family. The core hardware specifications — 64GB DDR5-4800 ECC Registered CL40 1.1V Dual Rank x8 288-pin DIMM — are consistent with the P43333 family. Verify compatibility with your specific HPE ProLiant Gen11 configuration via HPE QuickSpecs before deployment.

What is the difference between Dual Rank x8 and Dual Rank x4 at 64GB DDR5?

Dual Rank x8 uses x8-wide DRAM chips across two ranks — typically resulting in fewer chips per DIMM at 64GB. Dual Rank x4 uses x4-wide chips across two ranks — more chips per DIMM but potentially different signal integrity and slot population rules. At 64GB DDR5-4800, both achieve the same capacity and speed; platform compatibility and maximum DIMM population per channel may vary. Consult HPE Gen11 QuickSpecs for P43333-0A1 specific slot population guidelines.

Is DDR5 backward compatible with DDR4 slots?

No — DDR5 and DDR4 DIMMs use different physical connectors (288-pin DDR5 vs. 288-pin DDR4 with different key positions) and are not physically or electrically interchangeable. HPE ProLiant Gen11 servers with DDR5 memory channels require DDR5 RDIMMs exclusively. DDR4 modules cannot be installed in DDR5 slots.
