I have never overclocked before and just looking for a little guidance more related to my setup as opposed to reading through hundreds of threads and getting confused.

My specs:
Gigabyte GA-AB350-Gaming 3 motherboard
Ryzen 5 1600 CPU
G.Skill 4x8gb 2400mhz memory (although I can only use 2 sticks to be stable)

Long story short, I cannot run all 4 sticks of my memory unless I reduce the speed to 1866 mhz and even then its still slightly unstable so I assume I need to mess with timings and voltages.

I figure, if I am going to mess with timings and voltages, I might as well overclock then instead of underclock. So here I am.

1. Do I have to overclock my CPU in order to overclock my RAM?
2. Do I overclock the CPU first, get it stable, then work on RAM?
3. Do I simply just bump the speeds up and the rest adjusts itself?
4. How do I know what numbers to use/start with if manually changing speeds, voltages, and timings?
5. Would it be of any benefit to me to overclock my CPU and/or RAM? I dont game, but I do a lot of photo/video editing as well as a lot of AutoCAD and 3D rendering.

1) No.

2) Yes that is what I would do.

3) No. You will need to manually adjust voltages and timing, it wont change by itself if you just increase clock speed. I wouldn't go over 1.35v DRAM voltage with that kit. Post the model number of your kit and I might be able to suggest timings that may get you to 2400mhz stable.

4) Post the model number of your kit and I might be able to give you an idea of where to start.

5) Not entirely sure. Overclocking the CPU will increase render times slightly. Not sure if faster ram speeds and cpu speeds will help with CAD.

Using 4 sticks of ram on a dual channel motherboard is not ideal. It will impact the memory speeds you are able to achieve stable on your system, especially with a ryzen CPU. You may not be able to get 2400mhz stable unless you really slack up the timings.

first of all update your bios to the latest and try again.

1. no, even though memory controller is in the cpu, you don't need overclock cpu to overclock ram.
2. not really, they tends to be more independent, however it's good practice as you can isolate issues.
3. for cpu, you need to fix your voltage, set llc then experiment with the cpu multiplier, stay away from the base clock of 100 Mhz.
i'm not familiar with gigabyte bios, but the general concept is the same.
4. for ram, if your ram is not running at (2400 or 1200, it's probably at 2133 or 1066 speed depend on the presentation) you can turn on xmp profile to get the ram to run @ 2400 mhz, that should include all the timing for 2400/1200.
5. for ryzen, you get more performance by oc the cpu and ram. also cpu runs faster with faster ram speed as there is internal bus that take advantage of the fast ram.

I will try to clear up a few things and respond to both of you guys here.

I am currently on the F22 bios. There is an F23b out, but scared to try it as I read a lot of people having issues with it.

I am currently running at 2400 and stable, but only with 2 sticks in dual channel configuration and XMP on Profile 1 (the only profile I have). Its when I put the other 2 sticks in I cant post at 2400, so I need to lower the speeds to 1866 to get it to boot however I still get some random BSOD's. This is why I assume I probably need to make changes to the timings and voltages too. But if I am going to do that, would rather play with those settings with the 2 sticks installed and bump my speeds up rather than lower them...

Is my 2400 RAM capable of higher speeds?

The exact model of my RAM is F4-2400C16Q-32GFX

most new 2400 ram can be pushed to 2666 or 3000 with 1.35v and relatively loose timing at c16 or c18. however, based on my experience with ryzen 1600, the memory controller is no where near as stable as the intel one. you can try to rise the soc voltage to by 0.1 (i think 1.2 is the default value) and loose the timing on 2400 mhz. as for anything higher, i can't find it on gigabyte manual, but my asus manual indicated that 2666 and + are support for 2 dimm configuration only.

i am running my 1600 off a 2400 kit from teamgroup at 3000 16-18-18-38,

what i did is that i went to the memory maker's website, under the same series of memory but choose a ram sku that's running at higher frequency, and used it's timing.
