Size 64GB 2X32GB

  • 64 GB capacity in a matched 2 × 32 GB kit for full system memory
  • DDR4-2666 speed with CL19 timing delivers rated bandwidth for workstation workloads
  • ECC UDIMM corrects single-bit errors on the fly to prevent silent data corruption
  • 2 V operation matches the motherboard memory controller specification exactly
  • 288-pin unbuffered form factor fits ASUS WS C246M PRO and PRO/SE boards precisely

Exact-Match Upgrade Kit

This 64GB kit contains two 32GB DDR4 ECC UDIMM modules rated at 2666MHz with CL19 latency and 1.20V operation. It is built for workstations that require error-correcting unbuffered memory in a 288-pin form factor. The 2Rx8 rank configuration matches the memory controller expectations for compatible ASUS WS C246M PRO series motherboards.

Verified Fitment Steps

Installation follows standard UDIMM procedure: power down, open the chassis, align the notch with the 288-pin slot, and press firmly until the retention clips engage. The most common issue is ignoring the motherboard manual's specific DIMM population order, which can prevent the system from recognising the full 64GB capacity or booting at the rated 2666MHz speed.

ECC Unbuffered Requirement

This kit only works in systems that support DDR4 ECC Unbuffered UDIMM memory; it is physically and electrically incompatible with Registered RDIMM or SODIMM slots. Buyers whose motherboards require registered memory or non-ECC modules cannot use this product.

この商品に関する質問

How can I verify the kit is running at DDR4-2666 CL19 with ECC active after installation?

Enter the UEFI or use a tool like CPU-Z and confirm the memory frequency shows 2666 MT/s, timings read 19-19-19, voltage is 1.20 V, and ECC status reports enabled for the full 64 GB.

What exactly ships in the package and is any extra hardware required?

The box contains two 32 GB 288-pin DDR4 ECC UDIMM modules — no heat spreaders, cables, or tools are included and none are needed for installation.

Why choose this 64 GB 2Rx8 kit over a single 32 GB module or a 4-module set?

This 2 x 32 GB 2Rx8 kit matches the ASUS WS C246M PRO population rules for dual-channel operation at the rated 2666 MHz speed, while a single DIMM would run single-channel and four DIMMs may exceed the board's validated rank limit.
