Predator Orion PO3-655-RAM Installed in DIMM 2 & 4 Instead of 1 & 2 – Is This a Problem?

Hi all,

I recently purchased an Acer Predator Orion PO3-655 with the following specs:

Processor: Intel® Core™ i7-14700F

RAM: 16 GB DDR5

Storage: 1 TB SSD

Graphics: NVIDIA GeForce RTX 4070 SUPER (12 GB)

While reading through the manual, I noticed it recommends installing RAM in DIMM slots 1 and 2 for optimal performance. However, my system came with the RAM installed in slots 2 and 4.

Is this an issue? Has the RAM been installed incorrectly?

I only noticed this because I’m planning to upgrade to 32 GB and wasn’t sure where to install the new sticks.

Should I move the existing RAM to slots 1 and 2?


Thanks in advance for any advice!

    Placing RAM in DIMM slots 3 and 4 while leaving 1 and 2 empty will result in the RAM running in single-channel mode. The PO3-655 uses Dual-Channel Architecture, RAM sticks should be installed in adjacent slots like 1&2 or 3&4 to optimize memory bandwidth.

    Motherboards are designed to utilize memory channels for optimal performance. Typically, slots 1 & 2 and 3 & 4 belong to separate channels. When you use RAM in slots 2 and 4 (or 1 and 3), your computer can access data from both channels simultaneously, effectively doubling the memory bandwidth.

    When installing DIMM modules in PO3-655, populate the DIMM slots according to the table below:

    here's the specification details of the memory modules for this model.

    It's worth noting the actual numbering of those slots:

    So counting from the slot nearest the CPU they are numbered 4, 2, 3, 1. That means if the memory is in the second and fourth slot from the CPU, it already is in 1 & 2.
