RAM problems vary with AGESA versions from 1.2.0.5 to 1.2.0.7
RAM problems vary with AGESA versions from 1.2.0.5 to 1.2.0.7
On Windows 11, the fTPM in BIOS linked to an outdated AGESA version (older than 1.2.0.7) is causing stuttering issues.
I can share my perspective on this. My setup uses an MSI X570-A PRO paired with an AMD Ryzen 7 3700X. I've been using AGESA versions from 1.2.0.3 up to 1.2.0.6c. The experience has been consistent since July 2019. With AGESA 1.2.0.3 everything works smoothly. On AGESA 1.2.0.5 I encountered random BSODs, sometimes with XMP enabled and sometimes not. Restarting the PC was easy, but shutting it down and turning it back on triggered a repair BSOD each time. Updating drivers to the latest from AMD resolved the issue completely. My system runs a 32 GB Corsair Vengeance DDR-3200 kit (4x8 GB), which is listed as supported by MSI. I've confirmed no hardware faults with RAM tests.
The problem stems from micro stutters when TPM is active on most AMD systems running Windows 11 with Ryzen CPUs below AGESA 1.2.0.7. This version is designed to resolve the issues. We’re left with choosing between downgrading to Windows 10 or accepting reduced performance in our AMD systems that have performed well previously. Personally, I prefer Windows 11 and won’t downgrade, so I’ll have to compromise on speed for now.
Thank you for your input, it means a lot. Here’s the image I think clarifies the SMU story we discussed earlier.
Despite setting the memory frequency to 3000 Mhz with auto timings or similar settings like CL30 and sufficient voltage, it still doesn't function on these BIOS versions. However, once I switch back to 3801, everything operates smoothly at 3000 CL15 with 1.35v. I was able to perform OC RAM tests as well; I tried 3200 CL16 and 3600 CL18 without issues, and they worked too. You mentioned using "Thaiphoon" and a DRAM Calculator for Ryzen for this purpose.
I appreciate this design better; it's more readable now. I'll upload my version again so we can compare more easily (note: AGESA version wasn't detected, so I added it manually). It seems most components match except for the SMU version on AGESA 1.2.0.3c with Ryzen 5000 CPU. I noticed that Ryzen 1000 appears outdated (likely incompatible with W11), while Ryzen 2000 has a recent update in AGESA 1.2.0.6, but no further updates since the Ryzen 2000 APU. The Ryzen 30x0 APU and Ryzen 4000 APU both have new updates, and the Ryzen 3000 CPUs have newer SMU versions for each AGESA release. The Ryzen 5000 APU also has a fresh update. The Ryzen 3x00 APU (Picasso) is listed as well.
