Hi..
I have this problem with my Infinity mobo.. CPU and DDR voltages do not run at the specified bios value but at lower ones..

For example... if in the bios I set CPU voltage to 1.55 and reboot.. my current CPU voltage ( saw in the bios after reboot ) is about 1.50.. if I set it to default (1.50) It will be 1.37 .. and so on..
Same thing for the DDR voltages.. now it's setted at 2.8.. but current ddr voltage says it's 2.64 .. so If I want my ram to work at the default voltage of 2.6 I have to set it at 2.8

Is this normal or should I worry?
 
Mate,

Which BIOS are you using? Try 6-23. In my experience, this board OVERVOLTS the CPU and the RAM. The BIOS isn't very accurate. Should you be worried? Yes, if you see the same thing with the latest offiecial BIOS. Also,what PSU are you using and what are the Rail voltages?
 
I'm using the latest bios.. 10/19 If I'm not wrong.

My PSU is tecnoware 500W double fan.
 
Here are specs of my PSU directly from tecnoware website:
POWER SUPPLY DOUBLE FAN, INNER POWER SUPPLY (PSU) FOR PERSONAL COMPUTER, POWER 500 W, INPUT VOLTAGE 115/230 V, 50/60 Hz, MAIN SWITCH - OVERLOAD, OVERVOLTAGES, SHORT CIRCUIT PROTECTION - SPECIFIC OUTPUTS FOR P4 PROCESSOR, TEMPERATURE CONTROL, DOUBLE COOLING FAN, 20/24 PINS CONNECTOR, DIMENSION 150x85x172 mm, WEIGHT 1,4 Kg, SINGLE COLOURED BOX, 24 MONTHS WARRANTY

Unfortunately I do not have a digital multimeter.

Also.. chipset voltage seems to work fine.. it's setted to 1.5 volts and actually current chipset voltage says it's 1.5 volts.. so only CPU and DDR voltages are affected by this.
 
You can get one for real cheap from Radioshack. I was looking for the lectrical specs, not cosmetic specs. Something on the lines of (scroll down for electrical specs, i.e amps delivered per line etc...):-

Your PSU has NO ELECTRICAL SPECS on the datasheet! This is not good! Very suspect if you ask me! I would recommend junking that PSU and getting a more reliable one like the Fortron Bluestorm AX500-A. Before you do that, it would be good to see how the PSU does, with an actual voltage measurement,using a DMM. :)
