PSU Voltages and CPU temps

[t92300]

hi guys
i just got this new gigabyte mother board and in the bios it has PC health status

it has the following things what do they mean (i know some of the more obvious ones) and what should the be

Vcore 1.614V
DDR25V 2.608V
+3.3V 3.296V
+5V 4.992V
+12V 11.668V
System temperature 23deg C (i think this ones the case temp)
CPU temperature 48deg C

so any ideas fire away

thanks guys

Sounds like the Vcore is the voltage of your CPU.

DDR25V would be the memory.

Of course, system temp would be 23 Deg C. Room tempurature. Not bad, I guess.

48 deg for the CPU. My P4 at work runs at about 52. It's also in an air condititoned data center, so it doesn't flucuate much. But IIRC 48 is okay.

Not sure about the other three voltages.

Chips usually require a certain voltage to work, and different chips take different voltages. +5V is very common, and +12V is for more power hungry chips. All three are within operation tolerance. +12 is a little lower, but probably not enough to worry.

For a little more depth, the 3.3 volt (only has a wire going to the motherboard) is used for the motherboard and CPU

The 5 volt (red wire) is used mostly to maintain backwards compatibility with older CPUs, power expansion cards like PCI and AGP, and to power non-motherboard electronics like the microcontroller in a hard drive.

The 12 volt (yellow wire) is used to power motors in items such as your hard drive, cooling fans, and CD-ROM. Basically any moving parts.

However, these are just the common usage parameters. A device not connected to the motherboard can use either 5V or 12V or both to function. An item conencted to the motherboard can use any one of the three voltages (depending on how it is connected).

These are target voltages, and the actual voltages. As taper said, they're within operation tolerance. How do I know that? Well, taper said so! You might want to save a little note file of these numbers, to compare with later on so you can... um... note them.
