8GB DDR4-2666 ECC UDIMM

This Brute Networks module is an 8 GB DDR4-2666 ECC UDIMM built with major-brand chips. It runs at PC4-21300 speed with CL15 latency and 1.20 V operation. The stick is 100 percent HP compatible and matches part number 840755-091 for direct replacement in supported servers.

Suitable for HP server upgrades.

This memory suits administrators expanding HP servers that require ECC UDIMMs at DDR4-2666. Builders needing non-ECC modules, registered DIMMs, higher capacities or different voltages should look at other parts.

Deciding spec: ECC UDIMM at DDR4-2666

The single specification that decides fitment is the ECC UDIMM DDR4-2666 format. Only systems accepting unregistered ECC modules at this exact speed and voltage will support the part.

Questions about this item

Will this DDR4-2666 ECC UDIMM fit a standard 288-pin DIMM slot on an HP server motherboard?

Yes, the module follows the standard 288-pin DDR4 UDIMM form factor used by HP servers supporting PC4-21300 memory.

What is the correct way to seat this 1Rx8 module so the ECC function initialises properly?

Align the notch with the slot key, press firmly until both retention clips click, then verify 2666 MHz speed and ECC status in BIOS.

When should I consider replacing this 8GB stick if ECC corrected-error counts start rising?

Monitor the IPMI or iLO logs; sustained correctable errors on this module typically indicate it is time to swap it out.
