It might be a good idea to get the same memory brand, w/as close to the same specs, as possible.
Using CrucialScan, these are the modules in my GA14QM (Best Buy).Slot 1 (soldered in):
Micron Technology 4ATF1G64HZ-3G2E1 8GBSlot 2:
Micron Technology 4ATF1G64HZ-3G2E2 8GB
Here's Micron's Specifications for the 8 GB Modules above, as well as for a 16 GB and a 32 GB:Part Number; Module Density; Configuration; Module Bandwidth; Memory Clock/ Data Rate; Clock Cycles (CL-nRCD-nRP)
MTA4ATF1G64HZ-3G2E1and E2; 8GB; 1 Gig x 64; 25.6 GB/s; 0.625ns/3200 MT/s; 22-22-22
MTA8ATF2G64HZ-3G2J1; 16GB; 2 Gig x 64; 25.6 GB/s; 0.625ns/3200 MT/s; 22-22-22
MTA16ATF4G64HZ-3G2E1and E2; 32GB; 4 Gig x 64; 25.6 GB/s; 0.625ns/3200 MT/s; 22-22-22
The sad part is, the 8 GB is a single sided memory module, while the 16 and 32 GB are Dual.
So my guess is, a Micron MTA8ATF2G64HZ-3G2__, for a grand total of 24 GB, and a Micron MTA16ATF4G64HZ-3G2__, for a grand total of 40 GB; would be the ones to use, to replace the single 8 GB Module with.
I hope this helps people.
PS - This is the memory modules which appear to have come on my Asus GA14QM. You will have to check on yours, just to make sure you have the same. If different, you'll have to look it up yourself.
Once again, I used the memory checker CrucialScan from Crucial Memory to check what memory sticks are in my Asus GA14QM. I tried using PassMark, but for some reason, it wouldn't work.
