System-Specific DDR3 Memory Kit

This 64 GB kit contains four 16 GB registered ECC DIMMs built for the Dell PowerEdge R720xd. The modules run at DDR3 1333 with CL9 timings and 1.5 V operation. Quad-rank 2Rx4 organisation fills four of the system's 24 sockets. Computer Memory Solutions guarantees compatibility with the listed server.

Suited For Single-Server Upgrades

Ideal for administrators expanding one R720xd to 64 GB or replacing failed sticks with matched registered ECC modules. Not for workstations or desktops that require unbuffered memory. Buyers who need the full 512 GB maximum capacity should plan additional kits. Mixing registered and unbuffered ECC in the same bank is not supported by the platform.

Registered ECC With Quad-Rank Layout

The 2Rx4 quad-rank design is the specification that decides fit: the R720xd accepts registered ECC only and forbids mixing ranks within a bank. Each DIMM uses major-brand chips on a 240-pin PCB. Heat spreader presence varies by inventory lot. The kit delivers 64 GB toward the 384 GB registered ceiling.

商品問答

Will the 1.5V voltage and registered design limit how many 16GB modules the R720Xd can take?

The R720Xd supports up to 24 registered DIMM sockets for a maximum of 384GB using 16GB modules, so this 64GB kit fits well within that limit.

Does the registered ECC design change heat or fan noise compared with unbuffered memory in a 24-slot R720Xd?

Registered modules add a buffer chip that draws slightly more power per stick, but at 1.5V and 1333MHz the thermal load is similar to unbuffered ECC; the server's existing cooling handles both types without extra fan speed.

The kit lists four 16GB sticks but the package content says three — which count is correct for a quad-channel R720Xd?

The model number CM20487210600ECCR2R4H and the 64GB (4 x 16GB) specification confirm four modules; the three-stick mention appears to be a data error.
