Chosen Solution
Three slots were accessible and empty when I tried to boot it up. The last slot (which needs near-complete disassembly of the laptop to access) had a 2GB chip. The laptop failed to POST BIOS - I got steady LED lights and a battery light if a battery was present. Wasn’t sure if this 2GB was defective. Pop in two more matched 2GB chips (matched to each other but not necessarily the lone, inaccessible third 2GB chip) - laptop posts and recognizes all three 2GB chips, giving me 6GB. Did I need to populate the accessible bank of RAM slots first before populating the “split bank” (one slot on the underside, one slot on the topside). Is 32GB possible on this thing (4x8GB)?
If the motherboard was designed in such a way, it would require at least one slot from each bank to be loaded. Laptop motherboards aren’t standardized like most desktops, and that allows for OEMs to take creative liberty in their designs. If that one 2GB card was defective, it would still fail to post with the other cards in. Again, it may just be a flawed design. The maximum memory supported by your laptop’s motherboard is 8GB DDR3 @ 1333Mhz, as per ASUS technical specifications. 32GB of RAM is not possible on this machine.
