To the (tight timings) moon !! (R7 3700X + 3200CL16)

Hello all,

I see there are quite a few threads of people with the same "kind" of problem as mine. However, I prefer to open a new one as my questions might be slightly different.

First things first, the setup:

Mobo: X570 Strix-F (with latest BIOS available; version 1407)
CPU: R7 3700X
RAM: A kit of 2x 16Gb Crucial Ballistix Sport LT BLS16G4D32AESB .M16FE

All this in a Meshify C, with Noctua fans & decent airflow (well, at least I think it is ^^)

I planned to keep things at stock, but I read and watched many videos saying that basically, the "soft" sweet spot for RAM + Infinity Fabric was 3600 Mhz with the tightest timings possible.
So I went and bought this RAM kit, because it was decently priced and should be able to achieve what I wanted.

I ran the whole pc stock for a week, gaming for hours on end and all was fine.


Two days ago, I wanted to try my hand at pushing my RAM a bit. Not interested in tinkering with the CPU this time around.

Now, let's note that I'm a noob at RAM overclocking. And kind of a noob at overclocking all around anyway.

I read a quality post on Reddit that helped me A LOT to understand why I was putting which number where in my BIOS.

I also went and followed the instructions here for the DRAM Calculator for Ryzen.

So, like a good noob, I did exactly what I got in the FAST settings of the DRAM calculator:




Now, as is, it is running just fine from what I can tell. I gained a bit in Cinebench and a bit in a random benchmark of a game I used as a reference.
I tried to lowering the DRAM Voltage to 1.40, but it made me crash on Desktop after booting. I raised it a couple of times at like 1.42 and 1.44, just to see, but both time I crashed during games of CS:GO. I mean, the game crashed, and I went back to desktop, but that happened twice in a 30 mins span, so I went and raised the voltage again to 1.45. All is fine again since then.

I am not interested in going all hardcore on this, and tbh I'm happy with 3600 CL14.
BUT, I have a couple of various questions as follow, and I hope some more experienced people can enlighten me:


1. If I wanted to tighten the timings even more, could I run CL13 while disabling Geardown mode ? Or should Ryzen systems always have "even" timings and keep geardown enabled? Can't get a proper answer on that.
Because I feel I could squeeze CL13 here, but if I have to go down to the nearest even number, I feel like CL12 gonna require so much voltage that I don't wanna do it for such a daily used PC.

2. Is going into secondary or "third" timings really that necessary / useful ? I feel like I changed quite a lot of values in my BIOS, and I'm kinda discouraged if I have to spend super long into tweaking each one slowly, stress testing in between etc...
Do people "do that" or do you just set-up your primary and secondary timings, leave everything else in auto and call it a day ?

3. Related to question 2. what are usually considered primary, secondary and "third" timings ? So if you tell me I can just mess with 1st and 2nd timings, I know where to stop lol.

3. As a general point of methodology, I can't decide if I should lower the voltage then lower the timings or put the voltage super high, tighten as much as I can (but tighten what, only primary and secondary ? See question 2 ) and then work the voltage down ?

4. Is 1.45V considered "safe" for a daily usage ? I see that I could go to 1.8 in my BIOS, of course not doing that. Asking that because I feel like 1.45v is kinda high for daily use and I'd rather lower it a bit. But as my tests of yesterday proved, I can't maintain the timings I have now without 1.45 minimum.


Thank you in advance to whoever will offer some advice, I hope my questions are not answered everywhere on the forum and I'm just blind.

Also, as a french frog, sorry if my english "reads" funny.

Sup' guys, I will try some more tweaking tonight, because I still have some stability issues. Crashed once in game yesterday in a 2 hours and a half game session. Even with 1.45V.

Anyone would have an answer on at least this question, so I know if I should pull my hair about CL14, or if I can just go 3600CL15 and call it a day ?

Should Ryzen systems always have "even" timings and keep geardown enabled?

Because most of the discussions I see about RAM OC for Ryzen, people aim for even timings, CL14, CL16 etc... And I rarely see CL13 or CL15 mentionned. Is there a reason for that ?

Theoretically, do I "lose" performance if I disable geardown and run at CL15 ?
That would simplify the task if I didn't have to stay on even timings.

You need to stability test your RAM settings, seeing if games crash or not isn't really stability testing you could use membench with Dram Calculator or testmem5 which is my favourite. I'd also recommend the safe settings instead of fast.
