Should I do the pencil mod?

post #1 of 5
Thread Starter 
Well, this link (http://www.anandtech.com/cpuchipsets...spx?i=3184&p=5) shows why vdroop is implemented. However, would this same spike happen to a point to where it may fry the processor. Would it not because it is only for a short period of time? Wouldn't this kind of fluctuation because of vdroop be harmful to the CPU?

No, now a days, the new processors are more adept to handle a higher voltage (that's why we can OC xD) so it won't end up frying your processor, just don't go for like 3 V xD.

The spike is .02 - .03 so keep your max voltage at least .04 away from intel spec and Id say your fine


With mine i was running 1.4875 in bios (1.45 windows idle - 1.40 load) to keep my 3.40 OC.
Did the pencil mod and now I set vcore to 1.456 in bios, windows idle at 1.43 and load at 1.41.

Gave me lower temps at idle and made me feel more comfy...

The whole spiking thing is only important if your running volts close to intel spec. I see peaks around 1.48 on mine which is what most ppl run for 3.6.

But thos is just a theroy

I am running my E6750 @ 3.6GHz with 1.46v and I started prime95 last night, got up this morning and it wasn't there. It apparently rebooted because of a BSOD. Does a BSOD indicate that the voltage is too low or a temperature problem. It runs at 69C with prime running but that temperature shouldn't be too harmful for only a short period of time, right? I have seen people say that on these forums. When under load the voltage drops to 1.42v. I am thinking about doing this mod, but still unsure.
