Yeah, for Bank 4 only, configurable via MSR0000_0413 and MSRC000_04[0A:08] Machine Check Misc 4 (Thresholding) Registers. Also, see section 2.12.1.6 Error Thresholding in Fam10h BKDG. -- Andriy Gapon _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
