256 GB DDR4 3200 Kit

This kit supplies four 64 GB DDR4 modules running at 3200 MHz with CL16 timing and 1.35 V operation. The unbuffered non-ECC DIMMs use a 288-pin layout and a major brand chipset. Total capacity reaches 256 GB for memory-intensive workstations.

Ideal for high-capacity DDR4 builds

Suits users who need maximum density on platforms that accept 64 GB unbuffered DIMMs. Not for systems limited to 32 GB per slot or boards that require registered or ECC memory. Buyers needing error correction or lower voltage should look elsewhere.

64 GB per module density

Each stick delivers 64 GB in a single rank 2Rx8 configuration. This density decides whether the kit works on a given motherboard and CPU memory controller. Verify the platform supports 64 GB unbuffered DIMMs before purchase.

Questions about this item

How can I confirm the kit is running at 3200MHz with CL16 timings after installation?

Enter the BIOS or use a tool like CPU-Z to verify the memory frequency reads 3200MHz and the timings show 16-18-18 at 1.35V.

What exactly is included in the box and is anything else required to use the kit?

The box contains four 64GB DDR4 288-pin DIMMs; no extra parts are needed if your motherboard has four free DIMM slots and supports DDR4.

The kit is only sold as a 4×64GB set — how do I know this capacity is right for my build?

Choose this 256GB kit if your workload needs maximum capacity and your CPU and motherboard both support 64GB per slot; otherwise a smaller kit may be more cost-effective.
