64GB DDR4 2400 quad-channel kit

This OWC kit provides 64GB of desktop memory across four 16GB unbuffered UDIMMs. The modules run at DDR4 2400 with a CAS latency of CL17 and a standard 1.2V operating voltage. They use a 288-pin layout and carry no heat spreader or lighting.

Suits standard desktops

The kit is built for systems that accept non-ECC, unbuffered DDR4 at 2400MHz and can also run at 2133MHz where required. It is not intended for platforms that require ECC or registered memory.

Single deciding specification: non-ECC unbuffered

Because the modules are non-ECC and unbuffered, they will only work in motherboards that support that exact configuration. Verify the board accepts non-ECC UDIMMs before ordering.

Questions about this item

Will this kit run in a system that only supports 2133 MHz memory?

Yes, the modules are backward compatible and will operate at 2133 MHz if the platform requires it.

Does the 288-pin unbuffered design fit standard desktop DIMM slots?

Yes, 288-pin UDIMM is the standard form factor for desktop DDR4 motherboards.

Is any extra cooling needed since there is no heat spreader?

No, the modules run at the standard 1.2 V and do not require additional cooling.
