Hi guys.<br><br>
I got my new air cooling - the Freezer 7 Pro.<br>
Until now I was running my 805 at 3.5Ghz with stock cooling, and 1.325Vcore.<br><br>
I raised the FSB higher and reached 3.8GHz with my processor at 1.4Vcore.<br>
I'm NOT stable with dual prime95, so I guess I should raise the vcore some more.<br>
Problem is, the maximum allowed voltage according to intel for this processor is 1.4V.<br><br>
I heard that there's some kind of fuse that melts when exceeding the allowed voltage, and that it voids the warranty. I dunno if this is really true, but I'm wondering, should I raise the vcore some more?<br>
I don't want to lose the warranty, and I can always say I didn't overclock if I don't exceed the maximum allowed voltage.<br><br>
By the way, I have a serious vdroop due to my motherboard. CPUz reports that at idle the vcore is 1.28-1.32. on full load it's 1.264-1.28<br>
Should I trust cpuz's sensor? and if that is true should I 'believe' cpuz or the bios, in which I set the vcore to 1.4v.<br><br>
Obviously according to cpuz, I can go much much higher.<br><br>
Thanks for your help guys.

Droop is a serious issue, and if CPU-Z is reporting a low voltage, I'd keep bumping it up. I've seen higher than 1.4 on the 805 though <img alt="" class="inlineimg" src="/images/smilies/smile.gif" style="border:0px solid;" title="Smile">

If you're primary concern is the warrenty, then no, you certainly should not exceed 1.4. You may still have a voided warrenty as, depending on how the CPU fails before you send it in, they may still be able to determine the FSB it was operating at and prove overclocking.....unlikely, but possible. Also, the Intel maximum voltage is based on a CPU running at stock settings, within the listed thermal guidlines for a CPU to last 3 years minimum. An overclocked CPU within the listed voltages should stay 5-10c lower than the listed Intel thermal guidelines for a stock CPU due to the stress of higher FSB.<br><br>
The 805 can certainly take more than 1.4v, though it's service life would be in questions, especially on air temps.

Thank you.<br><br>
My main concern IS the warranty.<br>
I know intel has their ways to determine whether the processor was or wasn't overclocked, but as long as I stay in the allowed voltage range, I'm much safer.<br><br>
Question is, should I not exceed 1.4v in the bios settings? Or should I not exceed 1.4v in cpuz? I'm not sure if to trust cpuz's sensor.<br>
Obviously, cpuz reports a very low vcore. Actually the vcore I get in Cpuz is more or less stock voltage.<br><br>
About temps, I think I'm good. I'm getting 47c-48c on full dual prime95 load. The freezer's fan isn't at maximum speed either. 33c on idle.

While droop on the voltage is real, the only way to be sure how much voltage is going is to use a multi-meter. It also depends on how you use the CPU.<br />
<br />
If you leave it on 24/7 at full load (such as folding) then you should be fine adjusting the BIOS vcore higher to account for droop...however, if youy system does not go at 100% load often, then you would be better served to stay at or under 1.4v in the BIOS.<br />
<br />
Those are very good temps, especially on that hot little CPU. You should be trying to stay under 55c so are in good shape there.

You can fry it at 2.0V if you want lol, they can't know. If it dies and youve been exposing over 1.4V to it and they ask you if you overclocked it just say what is overclocking?<br />
<br />
Basicly, you can go over, just watch the temps <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" />

</div>Thank you. These are indeed great temps, especially due to the fact I'm already at [email protected]<br />
<br />
How can I check the cpu's vcore using a multimeter? Doing that on the PSU is easy, but where do I access the cpu without harming it?<br />
<br />
I'm getting different opinions here guys and really dunno what to do. I got the freezer so I can go further with the overclocking. I know my temps are great, and I want to do more. Only problem is that I'm really afraid of the warranty issue, and would prefer not to endanger it too much.

put more vcore, and don't worry about it. stay under 1.55v for now...<br />
<br />
It won't void the warranty or melt nothing at long as you're under 55C.

Why does it matter which temperature I am getting when it comes to warranty? I think the vcore has more impact, doesn't it?<br />
<br />
I had 60c on load at 3.5GHz before switching to the Freezer 7 pro.

The higher temperature has more of an impact on the life of a cpu than the vcore.
