64GB DDR5 ECC RDIMM for Dell PowerEdge

This 64GB DDR5-4800 CL40 module is an ECC registered DIMM built for Dell PowerEdge R660XS and R760XS servers. It delivers 4800 MT/s at 1.1V with a 2Rx4 organisation. The part replaces Dell part numbers AC239379 and SNPJ52K5C/64G.

Installation notes

The 288-pin RDIMM seats in standard DDR5 server slots and requires no tools beyond normal anti-static precautions. It will not work in desktop PCs or with unbuffered or load-reduced memory, so mixing types must be avoided. The module has no heat spreader.

Compatibility checklist

Verify that the target system is a Dell PowerEdge R660XS or R760XS and that the memory configuration allows registered ECC DIMMs. Confirm the server can accept 64GB single-rank modules at 4800 MT/s and 1.1V. Check existing DIMM population rules before ordering.

Questions sur cet article

How do I confirm the DDR5-4800 module runs at PC5-38400 CL40 1.1V after installing it in a PowerEdge R660XS?

Enter the system BIOS or iDRAC interface and verify the memory speed reads 4800 MT/s, CAS latency shows CL40, and voltage reports 1.1 V for the installed DIMM.

What ships with the 64GB ECC RDIMM and what extra parts are required for a Dell PowerEdge R760XS upgrade?

The box contains one 64GB 288-pin DDR5 ECC registered DIMM; no additional cables, brackets or cooling parts are needed for installation in the R760XS.

Which OWC part number should I order when replacing Dell part AC239379 SNPJ52K5C/64G in a PowerEdge R660XS?

Order OWC part number 4R8D52R464GB — it is the direct 64GB DDR5-4800 CL40 2Rx4 ECC registered replacement for that Dell part number.
