Combining same spec, different generation ram

I currently have 8 GB (2x4GB) of Kingston HyperX Blu Red Series RAM, it's 1600Mhz amd CL9. If I wanted to add more ram, the best case would be to add more of that exact same model ram, but it seems, that it is discontinued. Kingston HyperX Fury at 1600Mhz has CL10, the new HyperX Savage at 1600Mhz has CL9 again. So since my old HyperX Reds have 1600Mhz and CL9, theoretically they should work fine with Savages, right?

Attempting to use different generation modules, or even same part numbers that were made with a significant time between manufacture is highly likely, in fact, is most probable, to not work. Chip density, voltage requirements and a variety of other design differences can all affect compatibility. Even if they do play together, they may not play in dual channel.

It's always best to used matched sets or when that's not possible, at the very least use identical part numbers from the same generation, not from different generations as sometimes the part numbers get recycled.

If gaming is your main priority you're unlikely to see any performance difference using more than 8GB of RAM anyhow. Only seriously demanding applications will...

Probably be problematic, the Blu series used 2Gb memory Ics and the newer lineds of DRAM use 4Gb ICs, also the older Blu line , like most DRAM uses XMP where the Furry use PnP, best bet is just to get a set of the full amount you want, even if you can find the older Blu's there's no guarantee they will play nice

I know 8GB for gaming is enough (atleast for now), but I also use Photoshop, sometimes AutoCAD, usually have quite a lot of tabs open and sometimes, but no too often, run a virtual machine, to check out the latest Windows 10 build. From time to time I see over 90% ram usage.

So basically my options are: get the same ones (that are not guaranteed to work), or just get a whole new set
