To get DDR4 you would have to upgrade to a Skylake CPU or wait for ZEN and AM4. Totally different modules.
For AMD CPU's, it's the ones with iGPU's that benefit from very fast RAM. Yours is likely fine as it is. Also, unless you are running things like AutoCAD or video editing, 32gb is big time over kill, 16gb is the current "sweet spot" for RAM.
As for the timing, yes, they are higher, but the frequency is as well.
Thank-you, thank makes perfect sense to me... there's a ton of info out there, but not a lot of concise answers. Hence my asking here, and your answer is appreciated. :-)
I'll stick with my 16gb for now( have had the Silverline for 4 years now, VERY happy with them )and I've now got access to a free RAMdisk for some light video editing thanks to the MSI mobo software, should be all I need until I go to Zen.
Much obliged - you've all saved me from spending unnecessary $$ this season - more saved for Zen! :-)
