Brute Networks
Dell-compatible 8 GB DDR4-3200 ECC UDIMM with 1Rx8 rank and 1.2 V operation
This Brute Networks module is an 8GB DDR4-3200 ECC UDIMM built to match Dell part number SNPR8H4HC/8G. It targets administrators who need to expand memory in supported Dell servers with a validated, single-rank stick. The 288-pin DDR4 SDRAM operates at 1.2 V and carries a lifetime warranty. It is not for buyers who need registered DIMMs or capacities beyond 8 GB per slot.
Standard DDR4 UDIMMs at 1.2 V run within typical server thermal envelopes without extra cooling. ECC operation adds negligible power overhead compared with non-ECC equivalents. The single-rank 1Rx8 organisation keeps electrical loading low on the memory bus. Noise is not a factor for passive memory modules.
The module is ECC unbuffered (UDIMM), so it only works in platforms that accept unregistered ECC DDR4. Servers requiring registered (RDIMM) or load-reduced (LRDIMM) memory cannot use this part. Verify the system’s memory type before purchase.

Align the notch on the module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 3200 MT/s speed and ECC are active — skipping the BIOS check is the common oversight.
No routine maintenance is required; if a correctable error count rises or the module fails, replace it with another 1Rx8 8 GB DDR4-3200 1.2 V ECC UDIMM to keep matched ranks.
The JEDEC 1.2 V voltage ceiling is reached before thermal or timing limits, so the module cannot be pushed beyond the rated 3200 MT/s without exceeding spec.
