I will ask them for a D0 before I go to checkout

It never hurts to ask, but remember what t-ski said a few posts back. Just go back and look if you can't recall

What he said is super important to overclocking these beasts.

 

[n-ster]

If the guy doesn't know how to recognize a D0, or if you want to make sure, look for S-SPEC: SLBEJ on the sticker on the box

Just put together my fathers new i7 920 comp I spec'd out for him, and boy does that i7 920 overclock!!! With the noctua cooler I can get 4.2ghz stable and cooler than my temps of my q6600 at 3.6ghz. Gonna try 4.4ghz later this week, get everything good to go and get some screenies up here. Go i7's!!

 

[grunt_408]

I only wanna try for 4GHz anyway dont have watercooling only the choice of a IFX-14 or a Xigmatek Dark Night.

 

[kayawish24]

is their anyone having i7 950 ?? can someone tell me how to overclock i7 950 3Ghz to 4 Ghz?? what settings i shall do in bios and voltages settings etc ....
my system specs are:-

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

PSU: Corsair TX-850 Watts
wait i do it ..........

so here it is .....

here is little disturbing 4 me........

in full load temps didnt pass 80-81 @ 4 ghz still i will try to lower Vcore of cpu...

 

[mudkip]

I suggest you read some tutorials.

We can't help you. Every i7 clocks different.

If you try to overclock manually and you can't get out then you can ask for help, but you didn't even try yet.

 

[kayawish24]

but you can help me in putting values in bios...how other people overclock their i7 920 @ 4 ghz only on 1.256v???????? can i also put my vcore to 1.256 or lower to touch 4 ghz ???????

 

[t_ski]

It's not a matter of what someone else needs for their chip, it's what you need for yours. Read some tutorials, try a few things, and see what works for you. There are specs I listed back a few pages in this thread to help others get over 4GHz, but they're not a guarantee - only a guide. Your chip in your board with your ram is different that my chip in my board with my ram, even if we have the exact same parts. That's the law of OC.

 

[Thrackan]

can i also put my vcore to 1.256 or lower to touch 4 ghz ???????

Why don't you just try that?

 

[Tatty_Two]

Kayawish........ Are you really running three GTX260's off an 850 Watt PSU, albeit a decent one

As for your overclock and temps, as has been mentioned, you have your basic 4gig, what you need to do now is play around and incrementally reduce VCore and QPi volts to see how much lower you get, each time using the boot to windows as a basic stability test, then run something like OCCT for just a few minutes just to get a feel for those temps and stability. Try keeping VCore and QPi fairly near to each other.

And yes, read a couple of guides bercause they will give you the pointers because there is a lot you can do after the basic stuff with these chips, at some stage you might want to for example think about seeing how high you can get Uncore with it's dividers, a higher uncore can give you some nice performance increases but for now..... read and stick with the Vcore and QPi basics.

Just got my i7 rig up and running, got dual GTX 275s. Really starting to see some frame rate jumps in performance at 3.6ghz. Running 3Dmark vantage atm..post the results when I am done.

No one is giving you a hard time here, really. These i7 chips are unique. With s775 chips, it was much easier to give some bios values to plug in for an OC, and chances are, within a reasonable range, they would work. This is not the case with i7. These chips tend to vary so much in needed vcore and temps, that there is a good chance someone's settings will not work for you.

i think i shall change this v8 cooler to Thermalright Ultra-120 eXtreme 1366 - Retail

my be the temps go down

expect about a 2-3c difference in load temps. If you want anything more than that, you'll need water cooling.

hi guys im only a very basic overclocker but this is what ive found with my i7 920 and these r my specs.
asus p6t motherboard
i7 920 DO stepping
3x2gig pc12800 ocz gold CL 8-8-8-24
Noctua NH-U12P SE1366 CPU Cooler
corsair hx 620w psu
bfg gtx620 maxcore graphics card
antec 1200 case
ROOM TEMP WITH ALL THIS TESTING WAS AT 22C
so far all ive changed in my bios is my vcore and my vram cos i read about this dont put ur vram above 1.65 on this asus mobo or it could F**K ur cpu up so i have this at 1.64 or 1.65 depending on my overclcok.
i have had my cpu upto 4.0ghz no problem and all i do is turn up my fsb and drop my ram to the next setting under 1600mhz cos if i leave my ram at 1.65v and when i increase the fsb my ram goes up over 1800mhz and it wont boot unless i have my vram on auto which must mean that its putting it over 1.65v right ?

now here is my question....

i run my i7 with just 1.0v on vcore and turn fsb up so im @ 3.0ghz and temps @ idle r 29c - 33c
when i play call of duty 4 and 5 my temps r at 38c - 40c in game but my cpu usage while i play is only 8% - 20% so if i run prime 95 then sure my temps will go higher when cpu usage is a 100% upto 42c - 47c but i dont have any games or software that makes my cpu run higher than 30% - 40% % apart from power director 7 which is video editing and that can go upto 80% but thats it.
and when i overclocked to around 4.0ghz and i cant remember what vcore i had but if u want to know i can do it again my temps were around 40c idle and 50c in game but with prime 95 it went upto around 70c so i find that scary so i dont leave it that high but u guys keep going on about testing it to see if its stable but am i right in thinking i could leave it overclocked pretty high cos it wont get to these high temps cos i dont use anywhere near 100% load its always below 50% so temps stay cool.
when i 1st tested the temps @3.0ghz in game i thought this was amazing cos i used to have the q6600 and the temps where higher in game but i guess this is cos when i played call of duty 4 and 5 the cpu was using around 60% - 80% so it would be higher right ??? +vcore had to be much higher to get to 3.0ghz with q6600.

also ive not touched my QPi and i dont know what it is so its left on auto but should i be changing this to something else ? is there any kind of rule where it should stay within 1.0v or .5v of the vcore higher or lower ?
if there are any settings u wish to know that i use or other temps plz just ask and i will find out and post.

as far as I am concerned keep your qpi/dram voltage within .5 of your dram. I have ran DRAM over 1.65v as well as many other members. Nothing has happened. i'm not saying its safe to do 1.8-2.0v although it has been done, but you can go to 1.65-1.75v without a problem i would say. However remember keep your qpi/dram within .5v of your DRAM.

As far as temps, if during prime 95 temps dont go over 90ºc I wouldn't be concerned. This things go up to about 100ºc. I like temps to say under 80ºc. but thats a personal preference. Any other questions, ask away buddy.

little something i've learned. NB voltage (IOH), really never needs to go over 1.3v. THe QPI, I ran mine about 1.35v. I said ran because I am not overclocked any more. Crunching 24/7 all default settings, with speedstep on

 

[fireblade77]

so u say to keep my qpi within .5v of my dram but should that be .5v below or above my dram ?
and am i right in thinking if i up my fsb and it ups my ram over 1800mhz and i leave my dram volts on auto then this is putting it above 1.65v to get it to boot but i dont know what its putting it up to so how would u know it was safe unless u change it to manual ?

 

[fireblade77]

i am now at 4.0ghz with vcore @ 1.23v ram volts @ 1.64v and still qpi on auto (is this bad to leave on auto ?)
idle temps r 37c - 41c
full load under prime 95 63c - 70c
i guess gaming would be about 50c
ive attached photo of cpu-z and prime95 and core temp but its 1st time i try to show a photo in a post so not sure how to do it so might not work

It's bad to overclock your system. lol. If you can live with the risk of overclocking then NOTHING is wrong with your settings if they are stable. CP told you the ONLY golden rule with the x58 chipset and that is the QPI MUST be within .5V of the DRAM or you will fry something after about 10 hours of use.

Personally I'd never overclock on auto. It gives me a secure feeling to know that I can control voltages. Mobo can change settings without you knowing what. e.g. if your computer crashes you don't know why because everything is on auto settings. With manually settings you have a idea where to begin if you want to solve your problems.

 

[fireblade77]

so im right in thinking u want the qpi on as low as u can get away with like ur vcore but keep it within .5 volts of dram so my dram is on 1.64 so i want to see if i can get it to work fine on 1.14 or higher yes ?or paly it safe and start with 1.2v ?

first off, thanks binge and mudkip for the help also.

@ fireblade

THe QPI just keep it within .5 of the dram, at whatever you can get it stable, but just within .5v of the dram.

Dont leave your RAM at 1800 with the voltage on auto. TRy running the RAM at 1800mhz and set your DRAM voltage manually. TRy 1.7v, then go up slightly little by little and see if you can get it to boot and run stable.

[B]If you gather the info we have gave you, you'll notice the below:


I told you IOH voltage (north Bridge voltage) never really needs to go above 1.3v. So you can go ahead and set this voltage accordingly.

vcore, you know how to work it already and also DRAM, dont be afraid to go over 1.65v for the DRAM. Vcore try to stay under 1.45v, although if temps are ok, you can go higher for short periods of time (benchmarking for example)

QPI, must be within .5v of the DRAM, I ran mine 1.35v for a 4Ghz overclock with 6GB of RAM.

ICH (southbridge), u can leave that on auto or just set it to a voltage, slightly over default for a bit of assurance, but I would just leave it on auto.[/B]

So if you review the above in [B]BOLD[/B] we pretty much already discussed how to set most voltages so that you don't leave any on AUTO, at least the most important ones I would say. Keep us posted dude :toast:

 

[Thrackan]

I've already said this alot, but for everyone who just got started OCing their i7's:

Always try auto settings first.

You can reach at least 3.6 purely on auto settings without insane voltages being applied, and you can go ahead finetuning your voltages after that.

There are few reasons auto won't work:

• You're going past 4Ghz, the boards auto settings *might* not be enough. This is not weird: you're already overclocking >50%.
• You're heating up like hell and you need to finetune to prevent forest fires.

If you hit the barrier where auto-settings don't cut it anymore, read tutorials. There's a new someone every page asking the same questions.

Remember: overclocking is using your parts at speeds they aren't designed for.
Keep your expectations realistic. Building a NOS installation into your car, or drilling out the cilinders in your engine block, isn't easy either.
