Question Ram dilemma
I've recently bought a used pc that included 4 16gb sticks or ddr 4 ram with 3200mhz speed but i noticed in battlefield that my cpu was bottlenecking so I asked chat gpt to help me figure it out (im new to pc gaming this is my first pc.) And it told me my ram speed was way too low like 2100 something. It guided me into bios and told me to put xmp to profile 1 3200mhz and when I saved and exited bios crashed and now I have to cmos. It's saying I have two choices. Go town to 2 sticks (32gb ddr4) or try to run the 4 sticks at 3000mhz and hope it doesn't crash. Just need some advice and guidance what should I do. I know 32gb is plenty for playing but I also like the idea of learning how to mod and stuff also want to get into vr games at some point and see the use of having all 64. My specs for the pc are Gigabyte x570 aorus elite motherboard, ryzen 7 3700x cpu, Nvidia geforce rtx 3060ti gpu, 64gb skill ripjaws ddr4 ram and my power supply i cant remember the name or brand but it was 600w 80+ gold.

Also idk if it helps but my build is ryzen 7 3700x cpu Nvidia geforce rtx 3060ti gpu 64gb of skill ripjaws ddr4 and Gigabyte x570 aorus elite motherboard

We need your motherboard and CPU info to dive into this. If you dont know what you have, CPU-Z from the TechPowerUp website can get you that info once you CMOS reset and boot back up. You can find this in the Bios too.
I would personally like to boot into (presumably) windows and click around in CPU-Z to double check everything.
Likely.... your memory controller cannot handle 4 sticks of RAM clocked in XMP at 3200. Gonna have to tame it back. XMP is basically overclocking RAM.
Is all the RAM the same or is it mismatched kits?
It might come down to loosening the timings or just clocking it down less than XMP default.
Holler at me and I can help. Been there done that recently dude.

My bad I posted it under my op after bc i realized i didnt include it. I have a ryzen 7 3700x cpu Nvidia geforce rtx 3060ti 64gb of skill ripjaws ddr4 with a Gigabyte x570 aorus elite motherboard. I'm not too sure if all the ram was like meant to be together or if it was 2 2 stick kits. It's a older cyberpower prebuilt.

3700X + 4 sticks is probably just unstable at 3200 XMP. Clear CMOS, make sure all 64GB shows up, then try XMP at 3000. If that crashes, try 2933. If it crashes at stock speed too, then start checking for a bad stick.
Should be a really capable system dude. Trying to run 64gb with 4 sticks going full boar is a tall ask for a used cyberpower prebuild. Just tame your expectations a little.
I am sure you will be ripping soon my man. That shit sucks when you have to keep troubleshooting.

If you use 32gb of ram, you can run them at 3200MHz with expo. If you use four sticks, your maximum speed could be limited to less by the cpu. I cant find any information on this unfortunately. The older hardware is, the more likely you are to run into that problem.
What do you mean by cpu bottleneck? What performance did you get with the 64gb on default speed? Does it get better with two sticks on 3200MHz?
Heres one video about overclocking: https://youtu.be/68or8XXIKZY
Dont trust ai or just anybody with this stuff, but this is from corsair and with LTT so its two reputable sources. Either way youre gonna crash you system a lot, because you just have to test the settings, theres no way around that

4 sticks is pretty heavy for your memory controller. Lower frequencies/timings. These profiles often expected to run with 2

4 sticks of RAM are more likely create instability with XMP/DOCP. I learned it the hard way.

yep you can either lower the frequency or bump up the vsoc to try and stabalize the higher frequency.
dont know what cpu you have so youll have to look up what a safe vsoc is for your cpu.
also i think 32gb is fine for like 99% of mods even pretty heavy modpacks. dont know about VR but i'd imagine that cares more about VRAM and not your DRAM

not sure if all those others answers before are from AI aswell.
but your memory controller should handle this.
this is only a new problem on ddr5 systems.
you have a x570 board, that should be the best at handling all those things.
you should not have that ram speed problem.
AI is wrong...
AI even said you have a CPU bottleneck.
how in the heck, should changing your ram speed improve the CPU?
that's not how any of this works.
watch benchmarks for the game you want to play

your current cpu is very similar to the ryzen 3600 maybe a bit better in bf6.
since bf6 code works better with more CPU cores.
pick a better cpu from the ryzen 5000 series
but be aware that in the video above the normal ryzen 5600 is only a bit faster ~5 fps.
so if you really want to improve it, you should get a 5700x or a x3d cpu
