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.
