Voltage...yet again

post #1 of 11
Thread Starter 
I did a search but found nothing to my specific question.

I have my Vcore set to 1.525 which CPU-Z recognizes, but HWM says 1.54 and ASUS utility's say 1.53 full load 1.56 just sitting. Does this make any since to anyone? Why are my voltages all over the place like this and will 1.56 @ 44*c on a burn test harm the CPU for a 24/7 OC? I looked in my BIOS for settings regarding voltage swings but couldn't figure anything out. I want to blame my PSU but I'm not sure if it's at fault. It's a cheaper 4yr old Rosewill 750w that I bought when I first built my computer.

The Asus evo software is the most accurate one I have seen so far, cpuz and hwmon often report false voltages (usually their reads are same). In general, the higher the vcore, the more fluctuations are noticed. If you have set your vcore to 1.525v then after adding the effect of LLC (load line calibration) it should be near the value reported by the asus software. So, my suggestion is trust the asus report.
And yes, anything above 1.52v is pretty high for phenom 2 cpus and personally I would never use that high a voltage for 24x7 use. Fortunately, you have a good board which is supporting you with keeping that voltage relatively stable. If you must use that high voltage, it wouldnt be unwise to look for a better psu (dont really know the condition of yours).

A buddy of mine is a having a weird problem like you on a ASUS board as well, he sets his voltage to 1.23v but under load the voltage drops to 1.15 or sumthing :S

I'm not sure this applies exactly to what the op has asked, but that board has known VDROOP sensitivity.

I had a 650 watt ocz PSU that could not do anything above 1.5v cpu core because the voltage and clock would drop off drastically during load. I swapped it for a 750 watt corsair and haven't seen the issue since.

If that board has LLC (Loadline Calibration) option, try setting it to 19%.

You may be pleasantly surprised.

All of the various monitors will give different voltage readouts give or take a few .

Yep, only truly accurate way to know whats going on is to use a multimeter and backprobe the MoBo. In reviews, most MoBo's are actually better at voltage regulation than the software readouts would suggest.

Shrimpykins: It's just a joke man ease up. Haven't you seen Tropic Thunder? It's freakin hilarious and that guy is in it.

I can enable CnQ and the volts drop to 1.0 - 1.3 during regular tasks but it seems unstable with it dropping and adding the multi all the time with voltage jumps. I will try a multi-meter this weekend and see what it says. Where do I probe it on the motherboard?

When I was reading about OCing before all the guides said raise Vcore and watch temps until stable. So if I can't safely add volts without trashing my CPU what's the point? My temps at full load are completely with in limits and it's 24hr stable with prime95. I guess I miss understood what OCing is for. Please don't miss understand me I'm not bashing, I'm seriously confused. Only reason a red flag raised in my head is because after looking around on this site I found a bunch of people talking about Vcore's and if a certain amount is too much ect.
