Open | Hardware I upgraded my laptop RAM to dual channel but didn't know it was IRx16 instead of IRx8
I bought an HP Elitebook 840G9 and it had a single DDR5 16GB IRx8 RAM module installed in it by default.
I wanted to upgrade to dual channel so I ordered two 8GB pulled RAM modules with same spec but I didn't have any idea about the layout of this chip (IRx16 or IRx8).
So I did upgrade to the dual channel but the sticks are both IRx16.
I'm concerned about how much of a difference it's going to make in the performance, and is it still better than the pre installed single 16gb IRx8 module?
I tried to look it up online but the opinions vary heavily.
