Sometimes when I'm playing a game I'll get the following message from syslogd:

[16789.554414] [Hardware Error]: Corrected error, no action required.
[16789.554418] [Hardware Error]: CPU:0 (15:2:0) MC2_STATUS[-|CE|MiscV|-|-|-|-|CECC]: 0x98254000000c0176
[16789.554421] [Hardware Error]: MC2 Error: VB Data ECC or parity error.

[16790.541793] [Hardware Error]: cache level: L2, tx: DATA, mem-tx: DRD

I have an FX-9590 with 16GB of DDR3-2133. No problems actually occur so it's not really inconvenient but if nothing else I'd like to understand what's going on. I notice it mentions an ECC error. Is this just a memory error?

This might be a power issue like reported here:

Others report a BIOS problem with C6 state or a real CPU HW error. But I think power issue is the most reasonable for your description.

  • :/. I have a 1000W PSU and no UPS or any form of power filtering. Is there any way to diagnose this?
