What RAM Ryzen 9
Been away from the hobby for 15 years and need some advice on what RAM to get for my new PC build.
Goal is to build a water cooled rig that is as silent as possible. It's going to on 24/7 and live in a bedroom so I dont want to hear it wizzing away at night.
I've never done any OC before but my mate helped me pick a setup that should allow me to learn/try if I want.
I'm leaning towards 32GB of either 4x8 or 2x16 @3600hz. Thinking CL14 or CL16. Don't care for RGB so don't want to pay for it if I dont have to. Million Dollar question, what RAM should I get?
Here's what I have so far: Fractal Design Meshify 2 XL case, Be Quite Dark Power 12 850w Titanium PSU, Asus Crosshair VIII Dark Hero, EK Monoblock, Ryzen 5900x CPU, 2TB Samsung 980 Pro NVMe PCIe4 SSD, Asus ROG Strix 3060 OC GPU (still looking for Waterblock), 480 radiator with 4x120 fans, 420 radiator with 3x140 fans, EK reseviour/pump, Windows 10 Pro 64bit

Depends on the speed you end up with.
3600CL14 should be B-die. 3600-16-16 should also be B-die. In these cases get 2x16.
3600CL16 but not 16-16 get 4x8, especially if buying Crucial.
The question is, how cost effective do you want it to be? 3600CL14 is obviously faster than CL16 but the extra cost for B-die is quite high. Same with 3600-16-16. If you aren't doing manual memory overclocking (only enable XMP) then get 3600CL16 but not 16-16.
Also how set are you on the other parts, and what are you using this for? 5900X with a 3060 seems imbalanced for gaming, and the motherboard is overkill unless you are doing a lot of overclocking. You also don't benefit much from a titanium PSU. The power savings will never pay for the extra upfront cost, and the quality isn't significantly better than a high end gold unit.
Hey thanks for the input. Imbalanced in what way? I assume you mean the CPU is better than the GPU. If so I considered a 5800x for strick gaming but I got a killer deal on an open box retail 5900x.
3060 was all I could get at sensible money. The thinking was I could swap it out for a better model sometime down the line if/when prices ever come back to some sort of normal.
Mobo can be changed, not bought one yet, but it's a) possible to get a monoblock, b) it's comes highly recommended in research YT videos. I need 2x M2 PCIe4.
What does 16-16 mean?
Unfortunately I'm not into water cooling, so I don't know what other motherboards have compatible monoblocks available, but almost all full ATX X570 mobos support 2x PCIe gen4 NVMe. Some extremely low end ones don't but it's the main advantage of X570 over B550. And a 5900X doesn't need top of the line power delivery.
With RAM, there's more timings than just CAS latency (CL). Oftentimes RAM specs are listed with 4 numbers in addition to frequency (well technically transfers per second), such as 16-16-16-36 or 16-19-19-39. The 4 numbers are CL-TRCD-TRP-TRAS. When we say 3600CL16, we mean 3600MHz (technically MT/s) and CL16, without mentioning TRCD, TRP, or TRAS. 16-16 refers to CL of 16 and TRCD of 16. And 16-16-16 refers to CL, TRCD, and TRP all being 16.
Only CL is usually considered because it's the most important (usually) of the 4, but in this case I mention the TRCD as well since it's important here for identifying the RAM IC.
3600 16-16 is B-die. 3600 16-not 16 is generally not B-die (8Gbit DJR, 8Gbit Rev E, or 16Gbit Rev B are likely).
If you go to a RAM kit on PCPartPicker, among the specs listed in the left column (on PC) or if you scroll down (mobile) will be the timings. For example, the RAM linked below is 3600 16-16-16-36.

Makes sense. So 16-16-16-36 is a good spec? I had this kit on the list of potentials, thanks for your help mate!
It's good, but if you aren't doing manual memory overclocking then imo It's not worth the price over a 16-19 kit.
What’s the difference between the 32GTZN vs the 32GTZNC?
I purchased the NC and Besides the NC being cheaper. I can’t tell the difference.
32GTZN is 16-16-16-36 which is Samsung B-die.
32GTZNC 16-19-19-39 which is not B-die, probably Hynix DJR.
