System Voltages,?

Question

Hi All!

I was just wondering about my CPU voltage as well as other system voltages.

I Have a 500 watt power supply.

+3.3V-14A-----\
------------------|210W
+5V---25A-----/

+12V 13A ----- 210W
-12V 0.8A -----12W
-5V 0.5A ------5.0W
500 Watt Maximal combined output.
My CPU is a 1Ghz (1000Mhz) intel Celeron, Code name: Tualatin Technology 0.13um
I have it overclocked to 1.28Ghz (1280Mhz) Which it handles ok, no freezes etc.
The current FSB is 128Mhz, as you can see the multplier is 10x.
When i open up CPUZ and look at the CPU Core voltage it is 1.472Volts, but it is always changing, to 1.56V 1.24V even 1.88V, But only quickly. Is this OK?? even when it is not overclocked it still changes but not as much. When overclocked the Temp under load is 36 Degress C. Idle at 29

Also the ram is 512MB SDRAM 133MHz.

Also I have a NIVIDIA Geforce 6200 A-LE 256MB DDR2 GRAM. AGP 4x. 35 dgress C idle
45 under load.

The 3.3 voltage is running at 3.28V
And the 12V at12.16V

Thnx.

Answer 1

Voltage is not always exact so small fluctuations is normal. as far as the rest I'm not sure what you are getting at. A power supply rated at 500w should be plenty unless your total power consumption is greater than 500w (all pieces of equipment) In most cases output watt rating has nothing to with input watts. (hard to explain)

Answer 2

Your processor is just a 28 watter that has a stock voltage of 1.475V. It should not stress your power supply much even when overclocking. Your power supply voltage output is fine.

The Vcore fluctuation you are seeing could be due to:
1. Inaccurate voltage data from the sensor chip is being fed to CPUZ.
2. The processor voltage regulator on the motherboard has poor regulation. This is the one that could be potentially dangerous to the processor.
