I wanted to add some info regarding RAM and AMD APUs in case others run into the same issue.
I wasn't surprised that adding the other stick of RAM helped performance, since it essentially now runs in dual-channel mode. APU graphics performance are severely bottlenecked by RAM bandwidth, so running with dual-channel RAM essentially increased the bandwidth and gave a performance boost to your iGPU.
