TPU's Core i7 Overclocking and Feedback

Question: ain't that VCore a bit high for i7?

EDIT

Comparing this one to the one DaMulta just posted above, it seems that buying a 2nd 4870x2 is a waste, for now anyway. Maybe as drivers mature there will be a gain, in 3D06.

Still, i'm almost willing to bet that, in Vantage, this doesn't happen.

not when your at -50c LOL

I don't really know......I have ran my QX at 2.2v.......

I see what you mean: temps weren't shown in that pic.

2.2? DAMN!!!!!

I was so close to hitting the 5Ghz mark.....so I pushed and I pushed and I pushed.(Dom was on the phone with me that day.....)
Then clocked it back down to stock and ran it for 3 hours.....turned it off for a day.

The machine would not turn on for a week......

At first it had a -10c cold bug

then it worked with only 3 cores

Then it worked only at 1400FSB 4 cores

Then the cold bug went away

And now
ATM the thing does work stock.....I'll say that:roll:

That vcore concerns me too at only 4.1ghz. It's certainly fine for those of us on better WC or more extreme cooling for short periods of time. But considering the risk of electromigration that seems to occur on 45nm's over 1.45v, getting 4.0+ 24/7 is going to still be out of reach. It almost gives argument for people with good Q6600's to stay with them for quite awhile longer. Hell, the Q6600 I just sold was doing 3.9ghz on 1.48v stable.
I'm certainly not trying to be critical, and I'd like to be playing with an i7 too. I'm just trying to look at the value of the new platform.

HMMM.... I wonder why this is familiar, oh maybe I have been building and testing i7 systems for a while now :pimp: :rolleyes: I would say that I could throw up a CrossfireX score or 2 in Vantage (4870X2 x2 + i7 965XE ) :D
 
So what i can see from this, unless I have got it wrong, there is a fair bit of extra speed in these new chips, from my reckoning, an i7 at 4gig = a Yorkfield at about 4.3gig as far as the CPU score is concerned in 2006......thats really quite impressive.

Very true but if the i7 can do, lets say 3.8gig on 1.4v as a 24/7 thats still going to better any Q6600 upto and beyond 4gig 24/7 and they are rare......now my Q9650 will do 4.1gig 24/7 on less than 1.3v but hey sod the 24/7, bench the cr*p outta them I say! :rockout:

O with dice?
 
I know I should be able to do what your death clocks could do fit, only a little bit more.
 
Well fit with my phase I think I could take the chip around 4.5

I would like the 965 for the higher ram usage alone looking at that like.

I think I was around -20c on this clock or -30 down. Around there. That pic is saved on the 500gb drive that decided to die on me in 1 months time....
 
i havent done any "death clocks" with the i7. all my postings have been at stable speeds.

the i7s put off alot more heat. a phase tuned for 200watts would not suffice with the i7 chips when OCed.
 
I stayed frozen at 2.0v ask dom LOL

THATS A TON OF HEAT

The dang thing starts shacking LOL and reads I think(been a while)-62c on the front.

Real temp is still frozen at 2.0v

Is that not crazy? Now after the 2.0 V it's all down hill very fast.

dual or quad? 65nm or 45nm?

QX9650

I had the CPU Voltage at 2.0
PLL at 2.0
VTT around 1.8

Frozen but on the edge.


2.1 not frozen

2.2 about to over heat

Game over

But it kinda plays. Been meaning to RMA for a new steping.

Good article there, answered many of my questions. :)

See how he keeps saying (retail chips might have higher memory multiplier unlocked)

I think those chips clock better.

I don't think everyone really understands how to death clock yet.

A few fugger is stable at what 5.4 ?

But that's under cascaded phase -100c close to LN2. How ever I did read somewhere yesterday about a cold bug, and they were trying to stay above -50c.

I think I have seen more retail chips clocked higher than the samples, but I'm not 100% sure on that.
 
Where did all the benching go:(

Got the retention bracket for my CM Hyper 212 and it helps temps some, but damn these chips really get hot.
 
Just ordered the GIG Extreme, so need to get the chip and ram....

are you both just using hte 920i?
 
Did fit kill his machine?
