Memory Upgrade Help

[SethK]

I have Corsair LPX 16GB (2x8) of DDR4 @ 2133. In my general day use, I'm using 5-8GB, when using heavier and/or playing GTA V I sometimes get throttled. 

 

I am looking for the best combination to upgrade, whether I can use the old memory or not. I am also looking for cheap. I have an i7 7700k overclocking when i feel like it to 5.2, gaming max is 4.8GHZ or whatever that measurement is. Its been a while since I've messed with it all. RX480 8GB also with some wicked overclock that maxed out the asus software when pushing the limits. Z270H MOBO-max RAM 64GB @ 3866.

 

So, I can buy the identical kit (CAD 120), but its slow. Do I buy a 2x8 of 3866 (CAD 165) - would that be enough to solve my problem? Or do I buy some ripjaws V 2x16 @ 3200 (CAD 170). I know it's frowned upon at least but could i use my old stuff in the secondary slots with the new, faster memory? If not, what's a reasonable asking price for my og memory. Thanks!

I have a hard time thinking your RAM is being throttled by GTA V. The recommended RAM is 8GB so I doubt you're using almost double that. Also Linus released a video like two days ago talking about mixing memory. You should check it out here

Try to find same timings(or lower) but same MHz or higher, if you use XMP make sure the slowest kit is in slot 1 & 3.

I'm a multitasker, I always have multiple things going on; I may be working on school work at one point, have the notes open and resources, then ill take a break and play GTAV or cities skylines. I rarely get throttled for anything but it is the memory for the big games. I can overclock the RX480 to get a steady 60-80 FPS(depending on where in the map I am) at medium settings,1440. I know I could "just close" other things but easier said than done. I also render 3D occasionally so an upgrade will benefit either way.

 

I checked out the vid, pretty dang convenient timing but still left at relatively inconclusive for mixing. seems like too much work so I wont mix. But that still leaves me with - Do I buy an identical slow kit to get cheap but more space? Do I go with 2x8 GB of the fastest my MOBO can support (and will the speed offset be enough)? Or do I get middle ground speed 2x16? Every dollar I can save is good, but if I'm upgrading I want it to be the right choice. Here are my options. Ideally I dont spend much but is the 3600 32gbs worth pulling the trigger?

So i have no idea what XMP is, but I turned it on. But you're saying its worth trying throwing in new stuff of whatever speeds, just better, but put my current 2133 stuff in slots 1&3?

the slowest kit should be in 1 and 3 while 2 and 4 should be the new kit, make sure the new kit is not radically difrent. ^_^
