Hello,

About a year and a half ago, I bought a preassembled pc from Best Buy. 6 months ago, I started having problems of overheating, bad performances and blue screens.
You can find the exact specs on this page : http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en...
That is when I decided to start to updrade it. During the summer of 2011, I plan on building my first build, and the computer I currently own will hopefully cease to exist.
In the meantime, I would love if it did not explode. That is why I recently bought a Cooler Master HAF X.

The reason I started this thread is that while I was checking my specs with CPU-Z (it was the first time I used that program), I saw something that scared me a lot.
My Core Voltage was of 1.624V for a Core i7 920 @ 2791.64MHz !!! At idle, I have CPU temps that varie from 40°C to 48°C depending on the core.
Here is the full thing : http://valid.canardpc.com/show_oc.php?id=1504524

Problem is, I can't change any CPU settings with my crappy motherboard (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01...) !!!
From what I've read, the VCore on a Core i7 should be (at least for one that isn't overclocked) of 1.25V, and for one that is overclocked @ 4GHZ it should be around 1.35.

So basically, my question is, should I start panicking ? And if so, can I do anything about it ? Can I use software to change my CPU settings ? If not, will this CPU last until July of 2011 ?

Thank you for your help, and if you need my to clarify on anything, I'll be happy to oblige !

If CPU-Z or any CUPID Software detects that at all, go into the BIOS. But first, shut down your PC, IMMEDIATELY!

You could fry the transistors.

The thing is, it's been running like that for a year and a half, and as I said in my first post, I can't change any settings in my BIOS, because it is a crappy OEM HP/Pegatron motherboard.

Well, it might be software issue. In my theory...it might be a bad translation between the Software and the Firmware.

Hi al360ex,

Your temps seem to be just fine and as long as they dont go crazy high under load, you CPU is probably just fine. If you have not had any random shutdowns, crashes, or BSOD, then like dogman said it is most likely an error in translation.
