4 GB DDR3 UDIMM module

This single 4 GB DDR3 UDIMM runs at 1333 MT/s and fits standard desktop DIMM slots. It suits owners of older systems that still use DDR3 memory and need a modest capacity increase. The stick is unbuffered and non-ECC, matching typical consumer motherboards.

Replaces a missing or failed stick

Use this module when a system has an empty slot or a defective 4 GB DIMM and the board supports PC3-10600 speeds. The upgrade is worthwhile only if the platform cannot accept larger modules or faster DDR3 grades. Buyers who need more than 4 GB total capacity or higher bandwidth should look elsewhere.

Limited by the DDR3 interface

The DDR3 interface tops out at the 1333 MT/s data rate this module provides. Bandwidth and latency are fixed by that standard, so performance cannot scale with newer processors or chipsets. Systems requiring greater throughput must move to a later memory generation.

Questions about this item

What motherboard slot and form factor does this M378B5273CH0-CH9 UDIMM require?

It fits a standard desktop DDR3 UDIMM slot; the notch position matches the PC3-10600 keying so it only installs one way.

What is the correct way to seat the module and what step do people often miss?

Align the notch with the slot key, press down firmly until both side clips click shut, then verify the BIOS shows 4 GB at 1333 MHz.

When should the stick be replaced and how can I tell?

Replace it if the system fails to POST, shows memory errors in the BIOS self-test, or becomes unstable after re-seating and slot-swapping.
