I tried setting both PBO and auto OC settings in BIOS, and I wasn't happy with the results. When I decided to try a manual OC, I did it through Ryzen Master. It's not the "preferred" method, but it works with my setup. Up until I got this build I would never recommend a "software overclock" either. With that said, my last AMD build was a 965 BE that I only had for a couple of weeks and never bothered to OC, so I don't know any of the tweaks for these things. I've been relying on OCN and google-fu for my overclocking tips. Some people are able to get rated or better clocks with similar setups to mine with PBO or auto, and others aren't. In my case, I figure there's a really obvious "click here for moar mhz's plz" button that I am just not seeing. I'll probably go back and play with it more once I get my new pump, but honestly, 4.3 @ 1.325 is handling everything I throw at it.
How to: OC a Ryzen like a n00b, by the perman00b
1. Open Ryzen Master
2. Click "Profile 1"
3. Click "Manual"
4. Set each core to 4300 (or whatever your particular chip can handle, but most seem to be 4.3Ghz capable)
5. adjust the "Peak Core(s) Voltage" to 1.325 (you can go slightly higher if needed, but don't go crazy with it)
6. Click "Apply & Test", Ryzen Master will probably want to reboot. Let it do it's thing.
7. If everything worked, enjoy your new super simple OC.
How to: OC RAM
1. There's no shortcut, but you can use the DRAM Calculator
to get a baseline
2. Follow the instructions, and plug the numbers into your BIOS
3. Plug in ALL the numbers given by the calculator. Some of the values are linked to each other, so plugging in a few and leaving others at auto or default can actually cause MORE problems.
3. Tweak the numbers as needed to get the best combination of performance, stability, and temps.
1. Keep your IF and memory clock equal (coupled mode). It's hit or miss, but around 50% or so of 3700x's are capable of 1900Mhz IF, but I haven't heard of more than 1 or 2 that could surpass it without crazy high end cooling and power delivery.
2. #1 doesn't apply if you have really
fast RAM. Speeds of 4400Mhz or so are fast enough to offset the delay introduced by unlinking the IF and RAM.
