ooooooooooooooooooooooo!!!!!!!!!!!

sell your GTZ's guys.

the fuzion PWNZ it on i7.

all 4 cores are the same temp now with the fuzion.

^^did you make a custom mount for it? nice scores.

Chicken Patty · Jan 28, 2009

guess the new BIOS really helped went from needing 1.35v for 4.0 GHz to even complete a 3dmark run, to 1.305v and pretty darn stable. lets see how prime goes later tonight. Yes everything was open during that run, look at how long real temp has been open.

I'm curious as to what the core i7 safe temperature seems to be, you guys figure that out.

Impressive scores on Windows 7 beta btw. Im interested to try that myself on my q6600 once i partition my disk.

qpi/dram(vtt on some bios's) - 1.4 - 1.45 (depending on your cpu)

Isn't 1.45V VTT quite a bit over the 1.35V recommended spec for i7? I've been browsing various forums and nobody is really sure as far as i7 is concerned. I'm keeping mine at 1.35V for now.

I have a i7 platform now but I'm being careful about the voltages since nobody is really sure what the limits are. (It took months before people realized high VTT was killing 45nm Yorkfields) I got lucky and got the 3841 batch. I'm doing 4GHz with 1.38125V, although it is not Prime95 stable. Still tweaking.

max is 100ºc, i like to stay under 85ºc when that was a problem.

Those temps need to beat 27C on all 4 cores

That's what my GTZ is holding right now.

After running prime/tweaking for the whole day (4.2GHz) , the cpu now IDLE at 40C (28C this morning), and the rad started flowing warm air.

Core Temp #: 1 = 2, 3 = 4, and 1 & 2 = 63C, 3 & 4 = 67C degrees C, fullload.

HT always off, running prime with reduced QPI/VTT 1.3v -> 1.24v (passed 1 hour, gonna let it run overnight)

Now, i'm heading to bed... super tired. :toast:

dammit...

i keep getting

"clock interval not received on secondary processor"

needs more voltage i guess but im at 1.56v vcore now. maybe it wants something else?

temps are fine.

load temp is 54c which is actually really good for 4.33ghz

i usually fix that with vcore, at least on my chip. But thats already a lot of voltage.

how much voltage for those temps?

AddSub · Jan 30, 2009

I can do 3.6GHz with stock volts and 3.8GHz with with 1.3V as seen in the screen capture above. I'm pretty sure I can do 4.0GHz with less than 1.38125V. I just need to figure out which voltages do what, if anything, as far as stability is concerned. Lot of tweaking left to do.

1.387 Vcore (passed prime for 6 hours).
1.3 QPI/VTT

CPU PLL 1.86v
QPI PLL locked at 1.1v
Above is the setting stable at 4.2GHz HT off for my rig.

At 1.381 vcore, it crashed after 2 hours
Crashed after 1 hour and a half with QPI/VTT at 1.24v

All values are from Bios, not CPU-z.

I don't think I can push it any higher with reasonable voltages. I think 4.2GHz is best choice for speed/voltage ratio. Any higher with Corei7 920 is simple overkil voltage or chipset limited.

EDIT: I was able to boot into Windows at 210x21 @ 1.5vcore, 1.4 QPI/VTT, 1.9 CPU PLL, 1.3 QPI PLL, It did pass the SM 2.0 and SM 3.0 test in 3DMark 06 but it always crash at the CPU tests.

bro i have all voltages manually set to minimum, except for vcore, dram, and CPU VTT

here are my voltages and settings

YOu do have the EVGA board right?

Yeah, I have a EVGA X58. Am I correct in assuming that all of the other voltages aside from Vcore and VTT (and RAM voltage to some extent if RAM is pushed) are not that important? Did changing the PWM frequency do anything for you? So far I've noticed that the VTT voltage has the biggest effect on the OC. Vcore itself seems less important than VTT, at least on my setup.

no, vcore, ram and vtt are the only ones raised slightly, everything else is default.

I have my PWM at 800 KHz, havent seen the need to raise, does make your mosfets run hotter.
