No, this motherboard does not seem to have any spread-spectrum functions; I looked thru the BIOS setup screen and in the manual. AFIK power-saving is disabled. I do run [EMAIL PROTECTED] on both CPUs, which can make the system seem sluggish at times. Also hyperthreading is enabled so it appears as 2 CPUs. I was looking thru the ntpd code and in at least one place they claim to have made a fix that will work on single processor systems, but might not work on multiprocessor systems. I am considering moving it over to a Server 2003 single-cpu AMD 64 machine to see if the same problem appears.
The problem always seems to happen when the time offset is very small (< 5 ms) and is about to change sign. I wrote a Java routine to call ntpq every 5 seconds and I have been watching it for the last half hour. The offset just did change from -0.979 ms to 2.711 ms with no untoward result. It always happens late in the evening or in the very early morning. Verizon is making changes to its DSL system, and so there have been some outages and slow downs at these times. Also the 50 to 100 and one 500 PPM frequency jumps are always accompanid by a large time adjustment (on the order of .180 seconds). Do you have any more ideas?
