Overview
Dell AC239378 is a 32GB DDR5-4800 registered DIMM for 16th generation PowerEdge servers. It is a dual-rank module with x8 DRAM, and Dell's product name states that it is not compatible with 5600 MT/s DIMMs. Dell lists it with the manufacturer part number SNPW08W9C/32G.
Dell's catalog data covers a wide range of systems, including the PowerEdge R660, R760, R760xs, R760xa, R6615, R6625, R7615, R7625, R860, R960, T560, C6620 and XE9680, plus several XR edge servers and Precision 5860 and 7960 workstations. Both Intel Xeon and AMD EPYC platforms appear on that list, so one part number can serve a mixed fleet of 16G servers.
Before ordering:
- Do not mix this module with 5600 MT/s DIMMs in the same server; Dell flags that combination.
- Keep ranks and widths consistent. A 32GB 2Rx8 module belongs with other 2Rx8 modules.
- Some listings confuse AC239378 with Dell's other DDR5 parts; AC239377, for example, is a 16GB 1Rx8 module. Check the capacity on your quote.
DDR5 RDIMMs carry their own power management chip and split each module into two independent subchannels, so they do not fit DDR4 slots and cannot be mixed with DDR4 memory. A 32GB module per channel is a common baseline for general-purpose 16G servers. ICT Devices can quote AC239378 for single upgrades or full server sets; tell us the server model when you ask.
