Brute Networks
32 GB DDR4-2133 ECC LRDIMM with CL15 latency and 1.2 V operation for HP-compatible server upgrades
This Brute Networks module delivers 32GB of DDR4-2133 ECC registered memory in a 288-pin LRDIMM form factor. It operates at CL15 latency with a 1.20V supply and uses a 4Rx4 rank configuration built with major-brand DRAM chips. The part is validated as 100% compatible with HP servers matching part number 752372-581.
IT teams maintaining HP Gen9 or compatible platforms that require PC4-17000 LRDIMMs will find this a direct, tested replacement. Builders needing higher frequencies, lower latencies, non-ECC UDIMMs, or capacities beyond 32GB per module must select a different specification.
The decisive figure is the 4Rx4 load-reduced organisation combined with DDR4-2133 speed and ECC; the server memory controller must explicitly support quad-rank LRDIMMs at this data rate or the module will not function.

No — load-reduced and registered DIMMs use different buffering and cannot be mixed in the same channel.
Check the BIOS memory information screen or run dmidecode; it should show 32 GB per module, 2133 MT/s, ECC enabled, and 4Rx4 organisation.
Only the 288-pin DDR4 LRDIMM is included; no heatsinks, cables or additional accessories are bundled.
