HP 32GB DDR4-2933 ECC Registered DIMM — P38446-B21

The HP P38446-B21 is a 32GB DDR4-2933 (PC4-23400) ECC Registered DIMM in a single-rank 1Rx4 configuration, designed for HPE ProLiant Gen10 servers. At 1.2V with CL21 latency and 288-pin interface, it provides ECC-protected bandwidth suited for platforms where single-rank density and channel efficiency are prioritized.

Key Features

  • 32GB single-rank RDIMM — optimized channel efficiency for Gen10 Xeon Scalable platforms
  • 2933MHz (PC4-23400) for high-throughput server memory performance
  • Single-rank 1Rx4 architecture for lower per-rank electrical load
  • 1.2V energy-efficient operation with full ECC error protection

Product Specifications

  • Part Number: P38446-B21
  • Manufacturer: HP
  • Capacity: 32GB
  • Type: DDR4 ECC Registered (RDIMM)
  • Speed: 2933MHz (PC4-23400)
  • CAS Latency: CL21
  • Voltage: 1.2V
  • Ranks x Width: 1Rx4
  • Pins: 288-pin

Memory Specifications

  • Memory Standard: JEDEC DDR4-2933
  • Error Correction: ECC (Error Correcting Code)
  • Buffer Type: Registered (RDIMM)
  • DRAM Generation: DDR4

Performance Specifications

  • Peak Bandwidth: ~46.9 GB/s (PC4-23400)
  • ECC Type: Single-bit error correction, multi-bit error detection
  • RAS Features: ECC scrubbing, rank sparing, memory mirroring (platform dependent)

Use Cases

  • HPE ProLiant Gen10 balanced memory configurations
  • Virtualization and enterprise application servers requiring 32GB per slot
  • Database workloads on Intel Xeon Scalable Gen10 platforms
  • Memory channel optimization using single-rank modules

Compatibility

  • HPE ProLiant DL360 Gen10, DL380 Gen10, DL180 Gen10
  • HPE ProLiant ML350 Gen10, BL460c Gen10
  • Intel Xeon Scalable (Cascade Lake / Cooper Lake) platforms supporting DDR4-2933 RDIMM

Frequently Asked Questions

What is the advantage of a single-rank RDIMM over a dual-rank module?
Single-rank modules (1Rx4) present less electrical load per DIMM slot, which can allow higher population density in some server configurations and may achieve slightly higher memory speeds at full population.
Is P38446-B21 compatible with HPE ProLiant Gen9?
No — DDR4-2933 is not supported on Gen9. Gen9 platforms require DDR4-2133 or DDR4-2400 modules.
Can P38446-B21 be mixed with dual-rank DDR4-2933 RDIMMs?
Mixing single-rank and dual-rank modules is generally not recommended and may result in speed downgrades. Consult HPE QuickSpecs for validated mixed-rank configurations.

The HP P38446-B21 32GB DDR4-2933 single-rank RDIMM is a reliable Gen10 server memory solution. Order today — in stock at the lowest price.

Frequently Asked Questions

Why do I see an incorrect image for this item?

Product images are meant for illustrative purposes alone, and you may not always see the original image.

What do you mean by term Refurbished?

Refurbished means a used computer part or device that has been cleaned, checked, and repaired to make sure it works properly again. Unlike regular second-hand items, refurbished products go through testing and fixing so they can perform like new.

How many days does it take to ship goods to customers?

All orders are processed within 1-2 business days. Orders placed on weekends or public holidays will be processed on the next business day. For more info visit shipping policy.

What is your return policy?

Our Return Policy comprises a 30-day warranty for Refurbished products. There will be a restocking fee applied when you return non-defective returns. For further details, kindly take a look at our Return Policy page.

Do you deliver my ordered items in their original retail box?

For Brand New items, you will receive them in their original retail box. For Refurbished items, you will receive them in a Brown Box or Bulk Packaging.

Do your printers come with ink cartridges?

Refurbished printers do not come with ink cartridges or toners.
