Mem voltage, cpu voltage monitoring

Couple a queries for ye:

Is there a utility to monitor the memory voltage. Running DDR2 PC2-6400 mem at 400MHz (1:1). I set BIOS to +0.3 so presumably it's running at 2.1V, but is there some way to see it?

THis mem is 4-4-4-12, but CPUZ says 5-5-5-18 even though i've bumped the mem voltage...Do i gotta do sumthin else to get the better timings? Also CPUZ has Channels#Single...do i change this? How?

What CPU core voltages to believe?
BIOS =1.3375
CPUZ says 1.280
CoreTemp says VID:1.3375
SpeedFan has Vcore1: 1.28V and Vcore2: 1.98V
How are any of these related, if at all? I didn't realize the cores could have diff. voltages, but SpeedFan seems to say they are. If that's the case, what does the BIOS value mean since you can only input one value?

E6750 @ 3.2GHz (400MHz x 8)

Thanks lots!

  1. Well, I use PC probe to monitor all voltages in windows.

    The difference in bios voltages and cpuz voltages is due to Vdroop. The CPUZ voltage is what your CPU is actually getting. Power supplies and motherboards aren't good enough to give 100% of the volts you tell it to give to your CPU..

    My Bios has vcore at 1.425, but my CPU only gets about 1.38volts.

    BIOS should allow you to manually set your memory timings to 4-4-4-12 and you should check the manufactureres website for what the recommended voltage is for your memory. Mine is set to 2.2V in bios, but they actually get 2.28Volts in windows.

    I wouldn't trust Speedfan with the voltages.
  2. Any other utilities out there for us non-asus users?

    my board: P35-DS3L

    Download HWmonitor. It tells you a bunch of stuff.
  4. thanx...

    turns out SpeedFan just has weird labels.
    Vcore1 actually means cpu-voltage and matches up well with what CPU-Z reports (and HWmonitor)
    Vcore2, although stupidly labeled, is actually measuring Memory voltage.
