OWC 2U4D42R808GB 8GB DDR4 2400MHz CL17 1.2V 288-Pin UDIMM memory upgrade

OWC 8GB DDR4 2400MHz UDIMM for Lenovo IdeaCentre

This 8GB DDR4 module runs at 2400MHz with CL17 latency and 1.2V operation. It is a 288-pin unbuffered non-ECC UDIMM built to JEDEC standards. The stick is validated for Lenovo IdeaCentre 310S and 510S small-form-factor desktops. Buyers who need ECC error correction or registered DIMMs cannot use this module.

DDR4 2400MHz practical limits

The DDR4 2400MHz interface tops out at PC4-19200 bandwidth on this platform. The module is backward compatible with 2133MHz systems, so it will downclock automatically if the motherboard only supports the lower speed. Mixing faster rated sticks with slower ones forces the whole array to run at the slowest common speed. Systems limited to a single DIMM slot gain no dual-channel benefit from this single module.

Upgrading from 4GB or 2133MHz DDR4 in compatible

Adding this 8GB stick replaces a 4GB module or a 2133MHz stick to double capacity and raise the memory clock. The jump is worth it when the current RAM is the bottleneck for multitasking or larger files. Machines already populated with matched 2400MHz pairs see no speed gain from a single unmatched addition. Builders needing more than 8GB total must verify the board's maximum supported capacity before purchasing.
