Voltage Fluctuations...1.63-1.71

Here is what I'm running:
A64 Newcastle 3200+ running 240X10 at 1.5x110% in bios (1.63V) Temps are 40degrees idle, 63degrees load
1GB 512MB X 2 PC4000 Geil Ultra
DFI UT Lanparty nf3-250gb
36GB Raptor + 80GB WE SE
520W OCZ PowerStream


...now I'm ROCK SOLID stable at this Core Voltage, and nothing less. If I try anythine less, it reboots, or errors out in Prime95, but at the current settings, I can run Prime95 Priority 10 Torture Test, 3DMarks, Memtest for 48+ hours with no problems.

...the problem that I have is the Core Voltage fluctuates from 1.63V idle, to 1.71V on load! Is this normal? I know that the OCZ PowerStream iis considered one of the most stable PSU's out there...but I can't remember if I had such fluctuations with my 350W Antec, or 450W TTGI/SuperFlower. Should I be worried? Do I need to RMA the PSU? Should I mess with the adjustable settings on the back of the PSU?

...I'm using CPU-Z, and SpeedFan to get the voltage readings (which gives me the same readings)...is there any other program that I should try?


Thanks.
 
Software readings = inaccurate.

If they were really that bad, you would already have dead hardware.

you're probably right. I also noticed that my +12v readings were a little low, so I adjusted the adjustable rails on the back of the PSU (Love this feature!), and cranked up the dials a bit. It was 11.65, and is now 12.10. I also did the same for the +3.3, and +5, and they moved up from 3.23 to 3.28, and 4.89 to 5.00 respecively. I noticed that after tweaking these settings, the Vcore also stabalized, and is only moving from 1.65 yo 1.69 now. I guess I can live with that.
 
If you set your 12v baseline to 12.10 with a voltmeter your not leaving much safety room if something funky happens. Even if you factor in a 5% allowance you need to factor in a theoretical response time for the circuits to react.

CPUS cost too much to take that chance; I’d be inclined to back that down just a tad.

Just a thought
