welp, added a second stick of DDR4-2400 finally! this time $10 cheaper than stick 1 @ $35 (but man, i remember 8GB being $40 or so). completely unnecessary, tho :/ wish they had 2GB DIMMs as that would be just perfect for WCG+some GPU projects
also excited to see if it makes much of a difference in performance.
my prediction is minimal to no difference in CPU. possibly a small to moderate increase in GPU
