About the 370-AAFW
The Dell 370-AAFW is a Dell 32GB 2Rx4 DDR4-2933 RDIMM ECC Registered Memory providing 32GB of system memory operating at DDR4-3200 in a 2Rx4 288-pin RDIMM configuration. Built with tier-1 Samsung DRAM silicon, the 370-AAFW integrates Error-Correcting Code architecture to detect and correct single-bit memory faults in hardware. In Dell's memory portfolio, 370-AAFW provides dependable memory capacity and channel bandwidth for multi-tenant hypervisors, database servers, and HPC compute nodes.
Compatibility
The 370-AAFW module installs into standard 288-pin DIMM sockets across Dell PowerEdge platforms including R740, R640, R740XD, T640. Populating 370-AAFW 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-AAFW is governed by processor capabilities, auto-negotiating to supported memory bus frequencies.
How to identify a genuine unit
Genuine Dell 370-AAFW memory modules carry a serialized manufacturer label displaying DP/N 0HMA84GR7CJR4N, 32GB 2Rx4 DDR4-3200 specifications, and Samsung factory markings such as M393A4K40CB2-CVF. In iDRAC System Memory inventory, the 370-AAFW module registers with verified Dell SPD profiles, serial number, and rank configuration. Physical DIMM PCBs on the 370-AAFW feature gold-plated edge contacts with standard anti-static substrate coatings.
Buying used
When inspecting pre-owned 370-AAFW 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-AAFW channels to verify zero single-bit or multi-bit ECC errors under maximum memory stress. Ensure all 370-AAFW modules installed within the same memory channel share matching ranks, capacities, and part numbers.
