Modern power management mechanisms are quite aggressive, but increase

Try disabling C1E in the BIOS, and/or try disabling CPU frequency
scaling.

If the xruns do happen in regular time intervals, your problem might be
the BIOS which does something in SMIs (system management interrupts).
In that case, your only choices are to disable that BIOS function (if
possible; AFAIK only some IBM servers have that option:
),
or to get a different mainboard.
