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

Alex_0203

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.
