64 GB DDR4-2933 load-reduced ECC server memory with 4Rx4 organisation and 1.20 V operation
This 64GB DDR4-2933 module uses a 288-pin form factor and operates at 1.20 volts. It features ECC protection and a 4Rx4 Load Reduced design built with major-brand DRAM chips. The part matches HPE part number R0X06A and runs at PC4-23400 speed.
IT teams upgrading compatible HPE platforms to 64GB per slot will find this module validated for that role. Buyers who need unbuffered DIMMs, non-ECC memory, or speeds beyond DDR4-2933 should look at something else. The Load Reduced architecture also differs from standard registered DIMMs, so platform support must be confirmed.
The 288-pin DDR4 module seats in the standard server slot without tools. All orders ship with identically matched modules to avoid mixed-rank issues. The main risk is installing into a system that does not support Load Reduced 4Rx4 DIMMs at this voltage and speed, which prevents the server from posting.

Yes, the module uses a 288-pin DDR4 form factor and requires a server board with matching DDR4 DIMM slots.
Mixing 4Rx4 load-reduced and 2Rx4 registered DIMMs is not supported by HPE; populate each channel with identical rank and type for stable operation.
Check the BIOS memory information or the OS memory report — both should show 2933 MT/s (PC4-23400) at 1.2 V with ECC active.
