Targeted Asus M5 upgrade

This 8 GB DDR3-1600 module is built specifically for the Asus M5A78L-M Lx3 and M5A78L-M Usb3 motherboards. It fits the 240-pin DIMM slots and runs at the standard 1.5 V. The kit contains a single unbuffered, non-ECC stick so you can add capacity without replacing existing memory.

Steady throughput at CL11

The 11-11-11 timings deliver consistent latency during extended workloads rather than only in short bursts. Operating at PC3-12800 speed, the module sustains data rates that match the board's native DDR3 controller. Unbuffered architecture keeps the signal path direct for predictable response under continuous load.

Plain green PCB, lifetime backing

No heat spreader is fitted, so the low-profile PCB clears most CPU coolers and tight layouts. The 2Rx8 organisation uses major-brand chips validated for the listed Asus platforms. Computer Memory Solutions provides a limited lifetime warranty when purchased directly, guaranteeing compatibility or a full refund.

Questions about this item

How much heat or power draw should I expect from the 1.5V DDR3 module when the system runs all day?

The stick runs at 1.5V with no heat spreader, so it adds minimal thermal load and draws standard DDR3 power for an 8GB unbuffered DIMM.

What motherboard slot and chipset must I already have for this 240-pin DDR3 1600 CL11 kit to work?

It requires a DDR3 240-pin DIMM slot on an Asus M5A78L-M Lx3 or M5A78L-M Usb3 board; the chipset on those models handles the 1600 MHz speed natively.

Will this 8GB 2Rx8 stick run alongside the original 4GB modules already installed in my M5A78L-M Lx3?

Yes, the board supports up to 16GB across its two sockets, so adding this 8GB module to an existing 4GB stick gives 12GB total at 1600 MHz CL11.
