256GB DDR4 3200 SODIMM kit

This kit contains four 64GB DDR4 SODIMM modules rated at 3200MHz with CL16 timing and 1.35V operation. The unbuffered, non-ECC design uses 260-pin connectors and 2Rx8 organisation for notebook and small-form-factor systems that accept DDR4 SO-DIMMs. The matched four-piece set is intended to populate four slots for a total of 256GB capacity.

Who this suits and who it does not

The kit suits owners of DDR4 laptops or compact PCs with four SODIMM slots that support 64GB modules and 3200MHz speeds. Buyers who need ECC error correction, registered modules, or a different voltage should look elsewhere. Systems limited to lower maximum module densities or fewer than four slots cannot use the full kit.

What to check before ordering

Verify that your platform accepts 260-pin DDR4 SODIMMs at 1.35V and can address 64GB per slot. Confirm the motherboard or laptop BIOS supports 3200MHz operation and that all four slots are free for matched-pair installation. Ensure the operating system is 64-bit to utilise memory above 4GB.

Questions about this item

Does my laptop need 260-pin SODIMM slots to accept these modules?

Yes, each stick is a 260-pin DDR4 SODIMM, so the system must provide matching slots.

If I keep one existing 3200 MHz module and add this kit, will the whole set still run at 3200 MHz?

All modules will operate at the speed of the slowest installed stick; matching 3200 MHz parts will keep the kit at its rated 3200 MHz.

How can I confirm the kit is running at CL16 after installation?

Check the memory tab in CPU-Z or the BIOS memory information screen; both should report a CAS latency of 16.
