Vcore question

[geoffry]

Hi,

With my C2D the intel max recommended voltage is 1.50 V, does this mean what I give it in the BIOS or what it reads in CPU-Z? I've kept it a bit below 1.5 in the BIOS but CPU-Z reads it around 1.44 V idle.

Thanks

what you put in the bios.

offset and droop should never be taken into account. they protect agains load > idle state change voltage upshoots.

Thanks for the quick response.

While I understand your reasoning, shouldn't specific MBs be taken into account? The offset on my IP-35E is something like 0.10v with even further Vdroop.

+1 on Jag's comments.

Be Very Careful with pencil mods too when it comes to high voltage evening as well.

Its the voltage applied when it peaks off load and idle that you need to worry about. If you pencil mod at high voltage, according to anandtech's article, it can shoot up by as much as .07V.

So lets assume you used it to even out a high voltage mark. 1.55V When that chip pops off load, and on load, the instant votlage spike will peak up to 1.62V and flatten to as low as 1.48V

The low part isnt the scare, at worse, your comp will lock up and blue screen.
The high part is tho. On air, thats enough to zap your processor and could possibly kill it like a wolfdale. :T

Thats why Jag says its there for protection. And he's absolutely correct on this comment in most cases.
