Check for autosave crashes and hardware problems.
Check for autosave crashes and hardware problems.
I assembled a new machine this spring using the listed specifications. This was my first attempt at a custom build. I’m comfortable with computers but this was my first project. My Windows 11 Home v10.0.22631 is set up with one drive, and the second uses Ubuntu 24.04.2 LTS. The BIOS for the Z790 AORUS Elite AX 1.1 is the latest version. I’m experiencing several instability problems. Firefox and Brave tabs occasionally crash, not the whole app. When playing certain games on Steam—Stellaris and Rimworld are recurring issues—I face crashes during autosave around 30% of the time, whether on Windows or Linux. The same happens on my other machine (2019 MacBook Pro, dual-booted). I’ve also noticed Windows and the Linux kernel failing without clear causes. RAM tests with Linux tools passed without problems. At one point, I faced persistent kernel crashes with different error codes from Windows; I attempted a repair but it didn’t help. I backed up files, wiped the drive from Linux, reinstalled Windows, and even had it checked by a repair shop, who said a partition was corrupted. Now I’m unsure if hardware is faulty or if something else is at play. Thanks. Edit: After getting back, my PC displayed a Windows blue screen during a Solidworks installation.

Your PC probably isn't running smoothly. Based on your list from ppp, you should have four 6400mhz RAM sticks, right? https://pcpartpicker.com/product/g2FmP6/...m2b6400c32 If you use them with the default Expo profile, stability is likely compromised. The settings were designed for two sticks, not four. Consider testing with auto mode instead of Expo while you troubleshoot. If that works, you'll know where the problem lies. Then you'll need to adjust the RAM manually.
Your BIOS settings indicate the DDR5 Auto Booster is enabled, XMP Booster is off, Extreme Memory Profile is disabled, High Bandwidth is set to Auto, and Low Latency is also Auto. This matches your current configuration.
A different RAM type or using only two sticks could be an alternative solution if you're experiencing issues.

Corruption often follows crashes. Frequent random errors usually point to memory issues, especially when combined with the Machine_Check_Exception, suggesting a faulty CPU. It’s unclear if BIOS was updated, but Intel made mistakes on 13th and 14th generation chips by applying excessive voltage, leading to self-destruction. The main solution appeared in September, while the latest update came in May this year. Updating the BIOS refreshes the microcode for the CPU. Be aware that this patch only stops replacements from failing if the problem is confirmed; if symptoms appear, the CPU is likely dead. Intel has extended warranty coverage, making replacements straightforward. I can review dump files to verify, but with the Machine_Check_Exception it’s clear the issue is hardware-related. It’s a CPU fault, which is frustrating since it was mostly replaced by WHEA_Uncorrectable_Error after Windows XP. Exceptions exist only if WHEA isn’t initialized or the error log is empty—Windows depends on the CPU to log errors with its own and PCIe devices. MCE BSODs don’t provide much debugging value because they use XP-era CPU parameters, none of which apply to CPUs from 2005 onward. Check C:\Windows\Minidump for any files. If present, move the Minidump folder to the Downloads folder (use your desktop if you don’t have OneDrive syncing). Compress the folder and attach it to a post.
This seems unusual—the main problem is simply to adjust the RAM speed manually.
