About the 370-AHCS
The Dell 370-AHCS is a Dell 32GB DDR5-4800 Dual Rank Registered ECC RDIMM providing 32GB of system memory operating at DDR5-4800 in a 2Rx8 288-pin DDR5 RDIMM configuration. Built with tier-1 Samsung DRAM silicon, the 370-AHCS integrates Error-Correcting Code architecture to detect and correct single-bit memory faults in hardware. In Dell's memory portfolio, 370-AHCS provides dependable memory capacity and channel bandwidth for multi-tenant hypervisors, database servers, and HPC compute nodes.
Compatibility
The 370-AHCS module installs into standard 288-pin DIMM sockets across Dell PowerEdge platforms including R760, R660, R7615, R7625. Populating 370-AHCS 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-AHCS is governed by processor capabilities, auto-negotiating to supported memory bus frequencies.
How to identify a genuine unit
Genuine Dell 370-AHCS memory modules carry a serialized manufacturer label displaying DP/N 04K89M, 32GB 2Rx8 DDR5-4800 specifications, and Samsung factory markings such as M321R4GA3BB0-CQK. In iDRAC System Memory inventory, the 370-AHCS module registers with verified Dell SPD profiles, serial number, and rank configuration. Physical DIMM PCBs on the 370-AHCS feature gold-plated edge contacts with standard anti-static substrate coatings.
Buying used
When inspecting pre-owned 370-AHCS 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-AHCS channels to verify zero single-bit or multi-bit ECC errors under maximum memory stress. Ensure all 370-AHCS modules installed within the same memory channel share matching ranks, capacities, and part numbers.
