Question on CPU Voltage (P4 3.0ghz Prescott)

[ssmith]

I am running this system:

SuperMicro P4SCT
P4 3.0ghz Prescott @ 3.0ghz (not overclocked)
(2) 256mb Crucial Ballistix DDR 400 (PC3200)
CoolerMaster Vortex Dream ACC-U72 CPU Cooler @ 3000rpm (quarter setting)
Enermax Whisper 475w EGVPA PSU (fan on max)
Antec Lanboy Case (newest version) w/ (2) 120mm Fans
3Ware SATA-RAID 9500S-4LP 64bit PCI Card
(4) Seagate ST3120026AS SATA-150 120gb Drives in RAID5 for 360gb usable space
eVGA Nvidia 6800GT 256mb AGP 8x Video
Pioneer 8x DVD+-R/RW Drive (internal)
SB Audigy2 Platinum

My system is awesome, totally quiet, my CPU runs at 29 degrees C under normal load, system temp is around 34 degrees C under normal load. Everything runs great.

SuperDoc III motherboard monitoring tool reports an alarm during games of:
CPU Core A Voltage jumping from 1.34 to 1.86

I thought that was strange... but isnt that normal? Just a minute ago the alarm came up while i wasnt gaming, that said the same thing, CPU Core A was at 1.86, then jumped back to normal.

I don't get it. Should I be concerned?

Any insight/advice appreciated.

Thanks,
Scott
