It is dual rank with x4 DRAM devices and runs at 1.1V. Like other DDR5 RDIMMs it carries an on-module power management chip and splits the module into two independent subchannels, each with its own ECC bits.\u003c\/p\u003e\u003cp\u003eDDR5-4800 is the top memory speed for the first wave of DDR5 servers, including those built on 4th Gen Xeon Scalable and AMD EPYC 9004 processors, so this module fits the memory profile many of those systems shipped with. On newer processors that support faster memory, a 4800 MT\/s module runs at 4800. We have not found a manufacturer or OEM source that lists specific supported servers, so none are published here; check your server maker's memory guide for a 64GB 2Rx4 DDR5-4800 RDIMM.\u003c\/p\u003e\u003cp\u003eBefore ordering:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMatch the 2Rx4 organization with installed memory.
