Compatible DDR3 Kit for ASUS M5 Motherboards

This 4GB kit contains two 2GB DDR3 modules rated at 1333MHz with CL9 timings. It is built specifically for the ASUS M5A78L, M5A78L LE and M5A78L USB3 motherboards using 240-pin DIMM slots. The unbuffered, non-ECC design matches the board requirements exactly.

4GB Capacity with Four-Slot Headroom

The board supports a maximum of 32GB across four sockets, so this kit occupies two slots and leaves two free for future expansion. Everyday office tasks and light multitasking run comfortably within 4GB, while heavier workloads or modern gaming will exceed the available memory and require additional modules.

Upgrade from 2GB or Slower DDR3

Replacing a single 2GB stick or slower DDR3 modules with this matched pair enables dual-channel operation and restores full rated speed. The jump is worthwhile when the system currently runs below 1333MHz or has less than 4GB total, but it does not help if the board is already populated with faster memory or filled to the 32GB limit.

Questions about this item

Will these two 2 GB DDR3 1333 MHz modules run alongside the 2 GB stick already in my M5A78L board?

Yes — the board supports up to 32 GB across four sockets, so adding this 4 GB kit to an existing module stays within the limit.

How can I confirm the kit is running at 1333 MHz CL9 after installation?

Open the BIOS or a tool such as CPU-Z and check that the memory frequency reads 1333 MHz with timings of 9-9-9 at 1.5 V.

Does the package include only the two 240-pin DIMMs or are there extra accessories?

The box contains exactly two memory sticks; no cables, brackets or software are supplied.
