Excellent memory speeds! Would love to see some ARMA 3 benchmarks with some of that fast RAM.

For the last month or so been picking up parts as they go on sale, memory and cpu only thing I have left and the egg has this for $499 today. System being upgraded is my last 2600k so I run them awhile and this seems good for a longevity buy. About 18 hours left to decide :)

Just do it.

Down to memory and case for my build. What guidelines should I follow when picking out memory chips, using an asus z390 e gaming board.

Memory is pretty simple with Intel and comes down to what you are trying to accomplish (extreme overclocking vs simple overclocking). Intel is pretty good about memory.

Both of the 32GB 3200 kits below worked on both the 9900k and 2700X at XMP settings without issue.

I had seen some discussion on whether 2 modules instead of 4 were better, but unsure of the basis or actual impact.

Browsing in a mobile, but dont see anything linked as referenced.

These are $210 for a few days. Good stuff. 2 vs 4 sticks makes no difference.

For overclocking, 2 is better than 4. Get the lowest CAS timing modules that you can afford at the highest speed. In general, Intel isn't as picky with RAM so don't blow the budget. Also, RGB has a small impact on performance so factor that into your decision.

For example, a 14-14-14 3200 kit with b-die Samsung memory will be a good fit.

You could step up the speed to 3600 15-15-15 b-die Samung.

The link below has a good list of the memory used for various memory kits.

I was looking at some of the 3200-14 gskill sticks. Now trying to decide how much total and how many sticks.

As said above it can matter some when going for high clocks/low timings. It's not really about the number of sticks you put in though, but rather how many ranks of memory per channel. So let's say you want 32GB of RAM, it doesn't matter if you get 4x8GB or 2x16GB because you will be running 2 ranks per channel in both instances. 16GB sticks of DDR4 are double sided/dual rank, whereas 8GB sticks are single sided/single rank. There might be some 8GB sticks that are dual rank aswell but I think that was more when DDR4 was new.
So it's easier to run 2x8GB sticks at high speeds because they are single rank, but you can probably run 32GB 3200MHz CL14 without any trouble on Intel Z390, that's not a particularly high speed in this context. Always check mobo compatibility list or memory manufacturer compatibility list to be sure it will work out of the box, though.

Ah good reply, this is the talk that sounds like what I remembered. Now just to decide if I want to go 32 or stay at 16. What is everyone else running?
