Do you think that voltages in the 1.23 to 1.30V range are unreasonable? IDC posted some tables in this thread that pairs over-clock speeds and voltages. I think 4.7 Ghz required something around 1.29+V.
It's more that 4.6 requires something like 1.36V for mine. My wall is at 4.4Ghz.
Cooling isn't an issue. I've run IBT at over 1.45V just to see. Sure it's in the 80's, but it's almost 1.5V!
Same here! My i7 920 D0 actually runs at a lower Vcore for it's max overclock compared to the 3570KI've had a smattering of both.
My i7-930 did 4.0Ghz at well under stock voltage (but wouldn't go higher).
dqniel - Use a hacksaw or a mini-hacksaw and a pair of pliers to cut out your closed corners. Cut down each corner dam along each flange. Eight cuts leaves you with four tabs where the corner dams were. Then with a pair of pliers, reach the trough at the bottom of each tab. Grasping each tab with your pliers, bend. The base of the tab breaks off and you have open corners. That will allow you to mount your fan.
A link to a pictorial how-to is here.
Thanks for the link, but I've already done this before with a Dremel It's not worth the effort to me when additional Yate Loons with open corners are only $3.60 each. It's like an excuse to get more fans :whiste:
I have more than a hundred fans.
By the time you had your Dremel out and plugged it in I'd be done cutting out the corners of a fan. And you can cut too much with a power tool. I take your point, though. I have more than a hundred fans.dqniel said:Thanks for the link, but I've already done this before with a Dremel It's not worth the effort to me when additional Yate Loons with open corners are only $3.60 each.

And as everyone knows, the more fans in your rig, the quieter it'll run... :awe:
Apparently, setting LLC to 100% on the Asrock Pro4 doesn't mean what I thought it does.I don't even have to mess with that, but I could if I wanted too (the options are there).
For me, I just leave LLC set to "Auto" in the BIOS. It is magically delicious.
I'm measuring Vcc with a voltmeter too, and it is rock-solid at whatever I set it at in AI Suite.

100% - wild swings between Vcore idle and load (1.248V - 1.32V)
0% - MUCH more steady (1.248V - 1.262V)

Resurrected and recently much-mentioned is a fall, 2007 Anandtech article on overclocking the QX9650, which explains what happens with deployment of LLC.
While the article seems mildly reticent about using LLC or advises people not to use it, the main thing to take away from it is that it pushes upward a transient which exists in any case, cannot easily be seen or measured, and briefly increases the voltage to a level above the "maximum VID" which you set in BIOS. How those transients affect the life of your CPU is a matter of speculation, but become a greater concern the more you push the VCORE (load minimum, idle maximum) higher.

I dug around and found the actual link:
Intel Processor Power Delivery Guidelines (Cont'd)
Personally, I think Intel's engineers are a lot smarter than most of us and that we should keep the peak voltage below VID.
At 0% LLC on my Pro4-M the vcore rises when under load. I don't like that. At 50% it makes it so the vcore is above .020v below the set vcore when under load. That seems like the safer yet still acceptable vdroop, so I'll leave the setting at 50%.

We've also discussed and concurred about the size of the transient spike under lighter-than-stress-test loading, comparing the interaction of LLC, VCORE and vDroop to a rubber-band. Under light load, the transients are correspondingly smaller and of less consequence.
That being said, the prevailing wisdom cautions against increasing LLC to a point beyond that which just exactly cancels out vDroop.
My own LLC setting eliminates about 50mV of vDroop out of a total 80mV, so load VCORE still droops by about 30mV below the idle "turbo" VCORE. If LLC helps to reduce maximum IDLE VCORE, then one can imagine that voltage spikes may go no higher than before you applied LLC.
