Is the RAM not functioning properly at that frequency?
Is the RAM not functioning properly at that frequency?
Only confirmed for 2666mhz thanks to the CPU memory controller. Choose between a few paths:
1.) Set manually to 2666mhz and check if it works, review the outcomes and keep as is (I’ve tested extensively on first-gen Ryzen).
2.) Pick any frequency from your BIOS settings and try it, don’t worry about timing details since early models ignore them.
3.) Use the AMD Ryzen DRAM Calculator to adjust BIOS settings based on your specs and see if it posts.
4.) Perform benchmarks like Cinebench R20, Firestrike, and Prime95 for each option; if all pass, consider it stable.
5.) Prioritize frequency over timing—this generation is about that.
6.) Frequency won’t affect your CineR20 results at all; 2133mhz CL14 vs 3600mhz CL18 will match within error.
If you have more questions, feel free to ask!
AI Tweaker, I'm having trouble connecting to my rig with that board. It seems the other user is using it, or I could walk you through it directly. It works perfectly at 2133mhz because that's the default frequency where everything functions (roughly). But my memory can handle more, and a first-generation Ryzen would struggle without it—either because of dual-channel memory or the high frequency. Without that support, it just stalls at what it’s programmed for. Right now it operates normally, but its stability is shaky with XMP/DOHCP profiles. You can push it higher, and at 2666mhz manually, it will work (all components match at that speed) and you’ll see improvements. My rigs, when I play competitively, I set it to 2666mhz for guaranteed stability. For games like "basic white girl," I maxed it to 3200 or 3600mhz and got stable results on different boards. Because of the RAM link to Infinity Fabric, it communicates faster at higher frequencies—like running at 2.1GHz instead of 2.6 or 3.0GHz—which, based on my tests, means: depending on the game, the gap between 2133mhz and 2666mhz at full settings can swing from unplayable to barely playable (like in BF5 online). This usually leads to much tighter frame rates. If you want better performance, try setting it to 2666mhz in BIOS and don’t let it run too high. Upgrading the board won’t help much unless you’re aiming for a CPU upgrade—especially if your goal is gaming. I’m not sure about it, but this board probably has Zen2 support with a BIOS update. I’ve seen solid overclocking on my ASUS Prime board, reaching 3.8GHz at stock voltages, and I’m already strong in benchmarks with Zen2.
I don't think you are understanding. It will run. Sure - it may even be acceptable to you and not have any issues - its not supposed to at that frequency. That's why it posted (booted up) to that frequency. It works. What I am trying to tell you (and Im kind of done at this point unless you are interested in OCing the ram correctly, Im more than happy being helpful but convincing you is not what Im here to do) is that if you set it faster - you will get more gainz from your PC bro. Or don't, Im not sure I care lol. OR what you mean is that on CPU-Z when you are in Windows is showing 1500mhz, which is 3000mhz at Double Data Rate - which is it? (EDIT - and if that's the case why are you asking again in another post - in this one it seems you are asking why its running at 2133mhz and why not 3000mhz if you mean just in BIOS only and its already answered in another post Im not sure why we are wasting our time here).
The system automatically lowers its speed when DOCP/XMP isn't applied. This adjustment brings it down to a stable general frequency. If you haven't changed this in BIOS yet, that's normal behavior. Have you checked the DOCP options? Did you manually set it to 2666mhz without altering other settings? Note that your 24GB configuration seems unusual—have you added another memory module (like 8+8+4+4)? You're currently running a 2x8 2133mhz CL14 and a 2x8 3600mhz CL18 together at 2666mhz CL18 for gaming. If this setup helps you run smoothly, it should improve performance over the original 2133mhz.
