About the 370-ACNU
The Dell 370-ACNU is a Dell 64GB DDR4-2400 Quad Rank LRDIMM Memory Module providing 64GB of system memory operating at DDR4-2400 in a 4Rx4 288-pin DDR4 LRDIMM configuration. Built with tier-1 Samsung DRAM silicon, the 370-ACNU integrates Error-Correcting Code architecture to detect and correct single-bit memory faults in hardware. In Dell's memory portfolio, 370-ACNU provides dependable memory capacity and channel bandwidth for multi-tenant hypervisors, database servers, and HPC compute nodes.
Compatibility
The 370-ACNU module installs into standard 288-pin DIMM sockets across Dell PowerEdge platforms including R730, R630, R730XD, T630. Populating 370-ACNU requires adherence to platform channel balancing rules, and mixing Registered RDIMMs with Load-Reduced LRDIMMs or unbuffered memory within the same system is prohibited. Operating speed of the 370-ACNU is governed by processor capabilities, auto-negotiating to supported memory bus frequencies.
How to identify a genuine unit
Genuine Dell 370-ACNU memory modules carry a serialized manufacturer label displaying DP/N 06F89M, 64GB 4Rx4 DDR4-2400 specifications, and Samsung factory markings such as M386A8K40BM1-CRC. In iDRAC System Memory inventory, the 370-ACNU module registers with verified Dell SPD profiles, serial number, and rank configuration. Physical DIMM PCBs on the 370-ACNU feature gold-plated edge contacts with standard anti-static substrate coatings.
Buying used
When inspecting pre-owned 370-ACNU memory modules, examine the edge connector contacts for scratches, bent traces, or missing surface bypass capacitors. Run Dell ePSA embedded diagnostics or Memtest86+ across all 370-ACNU channels to verify zero single-bit or multi-bit ECC errors under maximum memory stress. Ensure all 370-ACNU modules installed within the same memory channel share matching ranks, capacities, and part numbers.
