HPE Apollo 35 memory upgrade

This 32 GB DDR4 LRDIMM module is built for HPE Apollo 35 servers. It delivers ECC protection and load-reduced buffering to maintain stability in dense enterprise environments. The single-rank 2Rx4 design fits a standard 288-pin DDR4 slot at 1.2 V.

IT teams scaling Apollo 35 capacity

Suits administrators expanding memory in validated HPE Apollo 35 configurations where registered ECC LRDIMMs are required. Not for desktop PCs, consumer motherboards or systems that accept only unbuffered UDIMMs or standard RDIMMs.

32 GB per module headroom

One module adds 32 GB at DDR4 2666 CL19, supporting virtualisation hosts and large datasets within the platform's qualified population rules. Capacity stops at the server's maximum DIMM count and rank limits; larger footprints need additional slots or higher-density modules.

Questions about this item

Does the HPE Apollo 35 need a specific BIOS revision to recognise the 32 GB DDR4 2666 CL19 ECC LRDIMM?

The module is built to JEDEC DDR4 2666 PC4-21300 CL19 1.20 V 2Rx4 288-pin spec; the Apollo 35 firmware that supports LRDIMM will detect it without extra steps.

Can I mix this 32 GB LRDIMM with 128 GB LRDIMMs already installed in the Apollo 35?

Yes — HPE Apollo 35 memory rules allow mixed LRDIMM capacities per channel as long as rank and speed match; this 2Rx4 2666 MHz stick follows those rules.

After seating the module, how do I confirm the server sees the full 32 GB at 2666 MHz with ECC active?

Enter BIOS or iLO and verify the DIMM slot shows 32 GB, 2666 MT/s, ECC enabled, and no correctable-error count climbing during POST.
