Instability detected in RAM at XMP profile 2
Instability detected in RAM at XMP profile 2
You're curious about keeping your RAM stable when using the second XMP profile. It functions well with the first one, but you experience occasional crashes on the second. Your system passes memory tests, yet Prime95 encounters issues during large FFTs. The error log highlights a hardware warning about rounding problems during a 384K FFT. Your specs match the model, and you're using the Ryzen 7 with precision boost settings. The drive is a Kingston 931GB KINGSTON SA2000M81000G, which can behave unpredictably sometimes. You're looking for more details to resolve this.
I’ll note that the Ryzen 2000 features a relatively weak memory controller, and trying dual-rank memory at 3200 might not work with your CPU. There are some adjustments you can attempt, but I’d probably spend about an hour on this. If it doesn’t stabilize within an hour, stick with 3000. Adjust the SOC voltage to 1.15V—avoid going above 1.2V for better CPU health, especially on Ryzen 1000/2000. The sweet spot seems around 1.1V–1.2V, which applies to Ryzen 3000/5000 but not sure about 2000. This voltage controls the memory controller, so increasing it might help. Experiment with the ProcODT setting; some boards have incorrect values and tweaking it manually can improve stability. Also play with RTT and drive strengths. These steps are really time-consuming and seldom successful, though they occasionally work. For my own sake, I’d skip this effort since it won’t boost the 200MT/s performance much. Consider updating the BIOS—newer versions likely offer better memory support, but it’s not guaranteed. Try a few different BIOS revisions and AGESA versions to see what works.
There are additional benefits to moving up to a 5700x resolution.
You have a 3080 GPU but are experiencing CPU limitations, so you're considering a CPU upgrade. Additionally, you're receiving a tax refund this year, making it a good time to invest in a CPU boost.
It would make sense. The 5700X offers solid performance, particularly when acquired at a low price used. It pairs well with a 3080. If you need it regardless of other factors, aiming for stable 3200MT/s might not be worth the effort, given the varying memory characteristics of each chip. The 5700X’s memory controller is impressive, and achieving DDR4 3800 on most boards is manageable, making the 3200MT/s target less critical.
