It is a single dual-rank DIMM built on 16Gb x4 DRAM, with CAS 40-39-39 timings, EC8 error correction and 1.1V operation. HPE PartSurfer gives P48502-001 as the spare number.\u003c\/p\u003e\u003cp\u003eHPE's server QuickSpecs list the kit for the ProLiant DL380 Gen11 and DL320 Gen11, and the DDR5 memory QuickSpecs list it under Intel-based servers only. For AMD EPYC Gen11 models HPE sells a separate 64GB 2Rx4 kit, P50312-B21. The module runs at 4800 MT\/s, which is the top memory speed of 4th Gen Xeon Scalable processors. Installed alongside 5600 MT\/s kits, everything runs at 4800.\u003c\/p\u003e\u003cp\u003eBefore ordering:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eKeep x4 modules apart from x8 modules such as the 32GB P43328-B21. HPE's Gen11 QuickSpecs advise against mixing them.\u003c\/li\u003e\n\u003cli\u003eUse the same capacity and rank in each channel where possible, following the server's population guide.\u003c\/li\u003e\n\u003cli\u003eCheck whether the server has an Intel or AMD processor before choosing a part number.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eHosts running many virtual machines or in-memory databases often standardize on 64GB modules because they reach large totals without filling every slot. As HPE Smart Memory, this kit is recognized by the server firmware as a genuine HPE part, and third-party modules are not validated by HPE. ICT Devices can quote it alone or as part of a Gen11 build.\u003c\/p\u003e","brand":"HPE","offers":[{"title":"Default Title","offer_id":45071857254583,"sku":"P43331-B21","price":3096.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0679\/1354\/7959\/files\/hpe-p43331-b21-64gb-ddr5-4800-rdimm-angle.png?v=1793864932","url":"https:\/\/ictdevices.com\/products\/hpe-p43331-b21-64gb-ddr5-4800-rdimm","provider":"ICT Devices","version":"1.0","type":"link"}
