Brute Networks
Adds 16 GB of DDR4 ECC registered memory at 2933 MT/s to compatible HP servers
This Brute Networks module is a 16GB DDR4-2933 ECC registered RDIMM built to HP P00922-B21 specifications. It uses major-brand chips on a 288-pin DDR4 SDRAM PCB and runs at 1.2V. The 2Rx8 organisation provides error-correcting registered operation for server platforms that require registered memory.
Administrators expanding HP Gen10 or compatible platforms that call for PC4-23400 registered DIMMs will find this module a direct match. Systems that require unbuffered UDIMMs, load-reduced LRDIMMs, or a different voltage cannot use this part. Buyers needing capacities other than 16GB should select a different module.
The single specification that determines compatibility is the 2Rx8 registered ECC organisation at DDR4-2933 (PC4-23400). The memory controller must support registered operation with this rank configuration and speed. Verify the platform qualified vendor list for P00922-B21 before installation.

Yes, the module uses the standard 288-pin DDR4 form factor and registered ECC signalling, so it must be installed in a compatible HP server slot that accepts RDIMMs.
Mixing different rank organisations is generally possible on HP platforms, but the memory controller will operate all modules at the lowest common speed and rank configuration supported by the CPU and BIOS.
Check the BIOS memory configuration screen or run a tool such as dmidecode on Linux to confirm the reported speed shows 2933 MT/s and the ECC status reads enabled for the new DIMM.
