Hello. I just assembled my new PC and I run CPUZ (latest version). My cpu voltage is constantly shifting between around 1.128v and 1.136v and sometimes it hits 1.148v or 1.176v. The core speed and real PSB also shifts a little bit. I don't think this is normal...

What can be the problem? The PC is not overclocked nor did I mess with the BIOS.

HELP!

By the way, the system is a Asus P5B Deluxe, a Core 2 Duo E6600 and a OCZ GameXStream with 2x1 GB Corsair DDR2 800.

Thats better :). I thought something was wrong. But shoudn't I keep Speedstep on? Or is it really better that I disable it?

By the way, my memory in CPUZ is shown as Channels: Single. Shoudnt it be Dual Channel?

Thanks!

Just a useful read, take a look at everything and you'll understand what your Intel Processor has been doing.

What kind of memory setup do you have?
How many Ram sticks do you have?
What is the Capacity of each stick?

I have two sticks of 1 GB Corsair DDR2 800 Dual Channel (total 2 GB). Twin Package, XMS2. So it should be dual channel, but in CPUZ it appears as Channels: Single under Memory and thats what I find strange.

Sounds like you have the both sticks of RAM in the same channel. To get it working in dual channel mode, you have to put the sticks in different channels.

It should be explained in your mobo manual, but usually each channel is coloured differently - you put each stick in a differently coloured RAM slot.

Yep. They are in each one's respective place (in Asus P5B Deluxe that is one yellow and one black). I don't know what to do...

In your particular motherboard, the MATCHING colors will result in dual channel mode. You should put both of them into the yellow slots.

Best of Luck

Thanks! I was searching for that info on the web (I was having problems understanding if one pair was dimms A1B1 or A1A2 and the manual just assumed that you already knew it) and I eventually found someone with the same problem.

Thank you very much to all of you! I'll change the position of the second dimm later this afternoon.

No problem. For future reference, they usually put the ram slots required for dual-channel spaced apart, to allow for better heat dissipation.
