64GB DDR4 3200 ECC UDIMM Kit for ASRock Server Board

This 64GB kit contains four 16GB DDR4 3200 ECC unbuffered UDIMMs validated for the ASRock Rack motherboard EPYC3451D4U-2L2T2O8R. Modules run at 1.2V with CL22 latency and a 2Rx8 organisation across 288 pins.

Suits ECC-capable servers needing 64GB.

Builders populating the named ASRock Rack board with registered DIMMs should look elsewhere because these modules are unbuffered. Systems that cannot use ECC will not benefit from the error-correction feature.

Four-module 2Rx8 288-pin DDR4 3200 CL22 kit

The 2Rx8 rank layout across four 16GB sticks decides whether the memory controller can address the full 64GB at 3200 MT/s; verify the motherboard qualified-vendor list for this exact configuration.

Questions about this item

How can I verify the kit runs at 3200 MHz with CL22 after installing it in my ASRock EPYC3451D4U-2L2T2O8R?

Enter the BIOS or use a tool like CPU-Z to confirm the memory frequency reads 3200 MT/s and the CAS latency shows 22; the modules operate at 1.20 V and are unbuffered ECC UDIMMs.

What exactly ships in the box and is anything else required to use the 64 GB kit?

The package contains four 16 GB DDR4 3200 ECC UDIMM modules (2Rx8, 288-pin, 1.20 V); no heat spreaders, cables or extra parts are included or required.

Why choose the 64 GB (4×16 GB) version instead of a smaller or larger kit for this motherboard?

This kit matches the board's validated 4-module population for 64 GB total capacity at DDR4 3200 ECC unbuffered speeds; other capacities would change the rank layout or leave slots empty.
