Restarting your new PC randomly.
Restarting your new PC randomly.
I recently assembled a new PC about two months ago and experience occasional restarts without any BSOD. Checking the Windows Event Viewer revealed a consistent error during these random restarts. There are no signs of freezing or other issues before the restart. A WHEA-Logger reported a fatal hardware error, with details pointing to a Cache Hierarchy Error in the Processor. The APIC ID is 8, and further information is available in the details view. Do you know what this error means and how to resolve it?
Based on the issue described, it may point to a problem with your CPU or its firmware. This isn’t a software error, so reinstalling Windows likely won’t fix it unless the driver is faulty. Often, an unstable CPU is the cause—have you adjusted its voltage, frequency, or FCLK before? Resetting it to standard settings might resolve the problem. If that fails, updating your motherboard’s BIOS to the newest version could also help, as firmware issues may be involved.
Yes I do undervolt with PBO at max negative 30 value and it pass all stress test no crash in game as well no crash. Except one game that I still not understand if it's undervolt problem or borken game. Btw I very offten get error STATUS_ACCESS_VIOLATION in chrome while watch Youtube not sure if can be as well due that ? Another strange thing that CPU run all time 4 Ghz+ even at idle and default BIOS values. CPU voltage never drop below 1V Btw I have Ryzen 5900X, 2 x 16 Gb RAM 3200 Mhz
It probably stems from the current configuration or settings. If you revert to the standard options or increase the voltage slightly, will the issue persist? The problem appears to be tied to the browser environment, possibly due to a malfunctioning extension.
The voltage drop is likely still insufficient; check if it fails under standard configurations without any undervolt adjustments. A game crash of this nature can occur, though it's rare.
However, my cooler is only a 240AIO and it runs hot even at the default settings. With PBO undervolt max, it reached around 70°C. I’m considering a default run now, but if that works, I’ll be lucky. I’ve heard most Ryzen 5900X models can handle a 30 value undervolt.
It looks like you're slightly under-volting the system, but you might be able to adjust it further without issues. If the temperatures remain high, try increasing fan speeds, using better thermal paste, or modifying your AIO's fan settings. You can also revert to default settings to test if crashes persist.
