TPU's Core i7 Overclocking and Feedback

fireblade77 · Jul 19, 2009

thx guys i have no problems overclocking to 4.0ghz with this i7 i just wanted to confirm i wasnt doing anything wrong as in leaving some things on auto which leads onto another thing :rockout:

im not worried about going any higher than 4.0ghz as nothing uses all of the 2.67ghz default except video editing which i will use it for, so when i run at 4.0ghz my vcore is only on 1.23v and my ram i leave at 1.64v @ 1600mhz i will take my qpi off auto and set to around 1.25 - 1.35 which ever is stable but do i need to take the nb off auto and set no higher than i think u said 1.3v or is it safe to leave on auto or is this gonna run to hot cos i dont think i have any way of checking the temps for the nb and sb ?

i think maybe im lucky with my i7 920 cos i can run @4.0ghz and temps will be 38c - 48c in game and 70c under full load on prime 95 and idle at 34c - 37c so would this be safe to leave it at 4.0ghz all the time ? i always turn the pc off when i finish at night so its not on 24/7 but i can game for 6 - 8hrs in a day sometimes.

ive been leaving it at 3.0ghz with vcore on 1.0v and idle temps 30c - 33c and 40c in game.
i think all this is pretty good from what ive been reading with air cooling.

Have you done any stability testing? If so, what did you use? Screenies or it didn't happen.

Jupiter · Jul 19, 2009

Guys i recently picked up an Exos2 750W external for $56
in perfect working conditions and much better then my Corsair.
I generally use 3.6Ghz as my 24/7 OC and i now have very
decent cooling with voltage at 1.08v.

With decent cooling i decided to see if i could push 4.5Ghz
on this 920 D0 chip. Notice the voltage...

Not bad, but less than 10 minutes of prime95 doesn't scream stable. Try 20 cycles of LinX or OCCT linpack for an hour. On a positive note, it does appear that your chip is similar to my DO, which has clocked over 4.5ghz on 1.36v.

fireblade77 · Jul 19, 2009

yes i know what u mean that it was a short test but like i said in one of my earlier posts .... thats at full load 100% but when i play games like call of duty 4 and 5 im only using between 8% - 20% of my cpu so am i right in thinking it will be fine for this ? :confused:

You still need to stress it for at least 8 hours. Or do about 50 passes of linx. it might be stable during games, but over time the instability will show.

@ chiken patty......

i have overclocked my i7 950 to 3.80 GHz with 1.27v.as my ram is XMP so QPI/DRAM is 1.3500 and DRAM BUS Voltage is 1.66..is this dan gerous because it was selected by XMP profile in my bios..and my temps after running prime95 for almost 2 hours were 80C in small TFT

My System Information
CPU: Intel Core i7 950 3GHz stock
Cooler:- Coolermaster v8
Board: ASUS P6t6 Revolution
Mem: 6GB Triple Channel DDR3 Corsair XMS3 1600MHz 8-8-8-24
GPU: Nvidia 3 X XFX GTX 260 Core 216 3 WAY SLI 715/1270/1431 (Core/Memory/Shader)
HDD: 640GB S-ATA Seagate Baracuda 32 Mb Cache 7200 Rpm
Sound: SoundMAX Full HD 7.1 Channel
OS: Windows Vista Ultimate SP1 x64 *Activated*

yes i also used MX-2 paste on cpu...
prime95 running on small tft for about 2 hours and these were the temps...and no crashes

PaulieG · Jul 19, 2009

Your voltages are fine, and while not dangerous, those temps are quite high. That V8 is not doing it's job all that well. What's your ambient temp?

kayawish24 · Jul 19, 2009

i already send money online for Thermalright Ultra-120 eXtreme S1366....coolermaster v8 is a bad choice

Jakethesnake011 · Jul 19, 2009

I was able to tighten my timings somewhat. I have not noticed much difference when running SuperPi or wPrime that much. Have not been able to get cas6 timings though.

I agree with Paulieg. Everything seems fine, but watch the temps. Hopefully the new cooler provides a bit of headroom for a better overclock.

nice job jake, not bad. How much voltage to the RAM?

Jakethesnake011 · Jul 20, 2009

Only needs 1.680V and 1.35V QPi to get it stable. I am happy with it cost me 70 bucks from ZZF when it was on sale. Rated for 1866 9-9-9-24 1.65V.

Jakethesnake011 · Jul 20, 2009

kaya
I would recommend lapping the TRUE and pressure modding it. That is the best way to get your money out of the cooler. You will notice when you install it you can easily move the cooler from side to side and it kind of spins ontop of the IHS of the i7. So I pressure modded it to stop that. I used about a 1/8" thick washer that was about 1.5" in diameter and put it under the i7 mounting kit. I also lapped the cooler down to 1600 grit sandpaper and both of those knocked about 5-8 degrees off my load temps. To me that is 4.2 instead of 4.0. If you dont wanna lap I would def pressure mod it, it kind of needs it to stay in one place.

not bad. my kit cost me $50, but I haven't tried to get it higher than 1528MHz I think it was. Had it at I think 1.68v and it was fairly easy to get it stable at that. Stopped my overclock there and now i'm at default settings so it runs at a much lower speed than that. Figured for everyday use, no overclock is needed. Keep my room cooler, save on the electricity bill. Whenever I wanna do some benches, I can just crank it up :toast:

Complete and utter blasphemy. BURN IN HELL, SINNER!!!!! :eek:

There is a difference, but still at all default it performs soo good. Crunches 24/7 I can still play any game, even Crysis Warhead while crunching and its all good. Nothing in my rig is overclocked now, nothing. Room stays much cooler, main reason why I'm doing it and to save some electricity. My bill was $328 with just this rig and a Athlon x2 crunching.

I don't run OC'd for daily use either.... *runs*

Does undervolting count?

Wile E · Jul 20, 2009

I run my OCed settings 24/7, but I do a lot of video encoding. If I had an i7, I'd probably only run a mild OC for 24/7, but an OC, nonetheless.

Thrackan · Jul 20, 2009

Got a waterblock set for my UD5 coming in this week. If all goes well I'll be making another clocking run when it's installed :toast:

Wetbehindtheears · Jul 20, 2009

What make did you get Thrackan? I've been considering MIPS blocks....

I've heard the MIPS are good, if not the best, quality, but I got a nice deal on the EK plexi set.
If you have doubts about the fitting placement, I'll be posting pictures here when I've installed them.

Wetbehindtheears · Jul 20, 2009

Thanks... will come in handy.

I'm still looking as I need to save first!!!
