OWC 32GB DDR4 2933MHz PC4-23400 CL21 1.2V 288pin ECC RDIMM memory upgrade

SKU CH-0W2T-3SQV7

32GB DDR4 2933MHz ECC registered DIMM for Supermicro X11 server motherboards

  • Total capacity32 GB
  • Rated speedDDR4 2933 (PC4 23400)
  • CAS latencyCL21
  • Rated voltage1.2 V
  • Buffer typeRegistered
  • Memory rank2Rx4

Capacity 32GB

  • ECC registered design detects and corrects data errors automatically
  • 2933 MHz DDR4 speed delivers high bandwidth for server workloads
  • 2 V operation reduces power draw and heat output
  • 2Rx4 dual-rank layout increases memory density per channel
  • Validated for Supermicro X11DPi-NT, X11DPL-i, X11DPS-RE, X11DPT-B and X11DPT-BH motherboards

Server ECC Registered DIMM

This 32GB DDR4 module is built for server and workstation platforms that require ECC registered memory. It targets administrators upgrading Supermicro X11 series motherboards or replacing failed sticks in 24/7 infrastructure.

CL21 2933MHz registered spec

The single specification that decides fit is the registered ECC design at DDR4 2933 with CL21 latency. Unbuffered consumer DIMMs will not work in these slots and mixing registered with unbuffered memory is not supported.

Frees DIMM slots for density

Each stick delivers 32GB in a 2Rx4 layout, letting you reach higher total capacity with fewer populated slots. It runs at 1.2V and is backward compatible with 2133, 2400 and 2666MHz bus speeds, so it drops into existing X11DPi-NT, X11DPL-i, X11DPS-RE, X11DPT-B and X11DPT-BH boards without voltage changes.

Questions about this item

What does 2933MHz mean once the module is installed in a server?

The module runs at 2933MHz if the platform supports that speed; otherwise it will down-clock to 2666MHz, 2400MHz or 2133MHz automatically.

How does the registered ECC interface affect usable bandwidth?

The registered buffer adds one cycle of latency but allows the memory controller to drive larger capacities reliably, so the rated PC4-23400 bandwidth is available when the CPU supports it.

What physical slot and clearance does this 288-pin RDIMM need?

It fits a standard 288-pin DDR4 DIMM socket and has no heat spreader, so it clears most CPU coolers and dense server chassis.
