Brute Networks
32GB DDR4-2133 ECC load-reduced DIMM with CL15 latency and 1.2V operation for Dell server upgrades
Brute Networks 370-ABUH-BN is a 32GB DDR4-2133 ECC LRDIMM built for Dell servers that require registered load-reduced memory. The module runs at PC4-17000 speed with CL15 latency and 1.20V operation. It uses major-brand DRAM from Samsung, SK Hynix or Micron and matches the Dell 370-ABUH part number for drop-in compatibility.
This module substitutes the original Dell 370-ABUH stick when a server needs more capacity or a failed DIMM must be swapped. The jump is worth it when the platform supports 4Rx4 LRDIMMs and the memory controller can address the full 32GB per slot. Systems limited to lower ranks or non-LRDIMM buffers will not benefit.
The 32GB capacity per DIMM provides headroom for multi-VM hosts, in-memory databases and high-thread-count workloads. ECC protection corrects single-bit errors to keep services running. The limit appears when the motherboard caps total memory below the desired configuration or when the CPU memory controller cannot address 4Rx4 modules.

Yes — the module uses the 288-pin DDR4 form factor and 1.20 V signalling, so it seats in any server DIMM slot wired for DDR4 LRDIMM operation.
Align the notch with the slot key, press straight down until both retention clips click; the common error is stopping at the first click instead of fully latching both sides.
Replace it if ECC logs show rising correctable-error counts, if the server reports a persistent memory fault on that slot, or after the rated service life for the platform.
