e7200 is this common? 4ghz - Page 8

post #71 of 79
Thread Starter 
LOL this **** still has me crackin up. On a side note, i get almost a full tenth of a volt vdroop. Does the pencil mod take care of that or does it just raise the voltage in general?

Vdroop is harmless in my eyes... okay so you have to take your bios setting and add a tenth... so what...

I have 5 hundredths (.05) of a volt drop

and I can manage this:
Note that everest is wrong on the temps, they are about 15*C lower

well. then if i want to run my chip at 1.33 like you I have to run it at 1.45 all the time, but under load it drops to 1.35 and still runs fine.. But there is all this talk about chips frying with too much voltage. So with it running at 1.45 most of the time and 1.35 under 100% primos load, is it going to burn up sooner?

Not sure but Im not letting windows readings touch 1.36 idle or load

I am sure the new boards like yours have defeated vdroop somewhat. But i still have a problem. Is my chip gonna fry if i send it 1.45 constantly so that under load i can get 1.35v??
post #76 of 79
defeated vdroop? I set 1.41 V in BIOS and I get 1.33 V in windows.....

@skydeaner,
when you set say 1.36 in bios that is what the peak overshoot voltage should be, so you are setting the max volts your cpu should see.

There is Vdrop (Voffset) which is the difference between bios setting and actual v. at idle (to help protect against overspikes)

Then an additional drop on max load, Vdroop, which helps again to protect against overshoot.

Some boards will have higher end electrical components that control overshoot better, and thus can have lower voffset/vdroop and still meet intel specs for cpu voltage. Boards with cheaper components that do a poor job of controlling voltage overshoot, will require higher voffset/vdroop to meet intel specs. And then again, maybe some boards dont fully comply with intel specs. Anandtech has good article on vdroop here and potential consequences off defeating it on 45nm.
http://www.anandtech.com/cpuchipsets...spx?i=3184&p=5

But the question you specifically asked, which does less damage to cpu, running higher or defeating Vdroop to achieve OC, I would like to know as well, but dont know that anyone has any definitive data.

But like xfreeroller, I am just keeping below 1.36 in bios for now, after running at 1.42 bios/1.39 cpuz for 4.2, I need additional 0.05v for all settings.

Well the board has very little voffset, it is just the vdroop under load that kills me. I wish i could stabilize it somehow.

Has anyone paired this a P45?
