I've tried changing my RAM frequency from the standard 2133 up to what my RAM supports, which is 3600. But sometimes when I change it, my PC reboots and then shows nothing after that. My mouse and keyboard don't turn on and start their RGB run though, and my monitors get black screens. Is there any way to fix this or do I end up stuck at the 2133 RAM speeds forever? I am using a ROG Strix b450-f motherboard paired with a Corsair Vengeance RGB Pro set at 3600MHz, running on a Ryzen 7 2700x from Zotac Gaming RTC 2060s.

Actually, what matters isn't how much memory you have but rather what your Memory Controller (IMC) is capable of handling. While you might get close to running at your Overclocked RAM's top speed if you try hard, it won't be reliable or stable without setting up the BIOS just right. You can't just pick a frequency and expect everything to work immediately; it needs special configuration in the system settings first.

There are three things that make your RAM go fast: the chip inside your CPU, the board on which it sits, and the sticks of memory you buy. If you try to push the speed too high, like going beyond what is officially supported by the chips, it might not even work right. Just try raising the speed in small steps from the bottom up until you see errors come back. That's all you can really hope for with your own parts.

I started by just setting the speeds in the BIOS what they say on the website I got, which is 3600MHz. Even though I tried 3200 nothing worked and my PC started acting weird until I basically reset everything back to default off of the motherboard. Are there other ways to do this but make it actually work?

Check your motherboard's website to see how fast your RAM runs with a second-generation CPU. The speed limit is 3,466 megahertz, but this applies just to three specific types of memory sticks.

It's not just how much RAM your computer supports, but what the motherboard's Memory Controller (IMC) can handle. You might get the top speed your overclocked RAM offers if you do it right, but you're missing a key step. Simply setting a frequency in the BIOS won't work unless you also set the right timings and voltage first. This specific information is stored on a chip called the SPD (Serial Presence Detect). When you start up your computer, the BIOS checks these values to make sure RAM boots safely. Because overclocked RAM needs different settings, you have to find them manually in the BIOS tools menu, usually under an SPD tab or in CPUz. Write down what you see there and type those numbers into the BIOS. Primary memory timings are just a list of four numbers, like 14-14-14-32 or 16-16-18-34. These numbers tell your computer how many clock cycles it takes to do one task. The smaller the number, the faster the RAM works.
