Core i7 920 at 4200MHz [Settings/Overclocking]

[Teddy944]

Whats the default voltage of a I7 920?

[chorinicpker]

drop your voltages! your gonig to kill ur cpu! i can get 4.2 with only 1.3 v core.

[Robbaz]

dont worry they are 1,38v now.

[chorinicpker]

drop it down to 1.3.

[Robbaz]

Can't i got a c0 i bought my processor in december last year. It's soon a year old.

[chorinicpker]

oh. well what is your temp's and what cooler are u using?

[Robbaz]

check my channel video, it's a h50 push pull. i land at 75c peaks full load prime for 4-5hours.

[chorinicpker]

nice, i got same cooler. i load at 68c and idle at like 43c

[NAMkiller]

robbaz, i think you should really lower your voltage, it is way too high for only 4.2mhz. your pc will perform better at 4ghz with higher memory speeds.

[badboysergio]

is it stable

[Yytinen]

Where is the right place to look at i7 920 voltages? My bios shows me 1.475 but in cpu-z it is only 1.392. Which is the real cpu voltage?

--yytinen

[NAMkiller]

put your pc on prime and look at cpu-z, that will be your true voltage. btw if you are using a 920 d0, dont put the voltage above 1.35...

[Yytinen]

I have d0 but why not above 1.35?

[NAMkiller]

1.35v is high enough, any higher is putting too much voltage through, especially on air.

[Yytinen]

I have liquid cooling system and someone told me below 1.5 is safe. But what do you recommend for liquid cooled i7 920? (Cooled by Zalman reserator and swiftech apogee gtz block. (Allways in prime 95 temperature below 80 somewhere near 75) Thanks in advance.

[Yytinen]

And those are for overclocked at 4.4ghz.

[NAMkiller]

when you run prime95, what does the voltage say in cpu-z? if that is around 1.37 or below then thats good for 4.4ghz at those temps :)

[Yytinen]

Well those temps are with 1.42v from cpu-z. But is it so if cpu is cool enough little overvoltage wont hurt it ?

[NAMkiller]

personally i would not put that much voltage through my chip as it has a high chance of being damaged, 75c isnt very cool but it is acceptable with lower volts than that. I would be careful putting that much through your chip if i were you...

[Yytinen]

Ok I will drop my voltage, but do you have any advice to me because my cpu will boot at 4.4 1.36v but it is not stable and it need over 1.42v to be stable. Is there some other voltage to adjust because it is d0 and it should not need that much voltage?

[NAMkiller]

have you played around with the cpu pll voltage? try putting it to 1.98v and see if you can get the cpu stable at under 1.4v, worth a try. What board are you using?

[Yytinen]

I have gigabyte ex58-extreme and I tried 1.344v adn 4.3ghz and it worked.

[NAMkiller]

thats perfect! you wont notice the difference from 4.3 and 4.4 apart from your chip will last longer :)

[Yytinen]

Yep thats true. I raised northridge voltage little bit and it worked like a dream. I have also watercooled my northbridge so it wont hurt it. Thanks for your advice.

[r2stik]

SEE VIDEO OLI JUBA TÄITSA OK :)

[speedaddict2008]

HOLY SHIT.

[mariojunior1992]

Super PI in Used is Incorrect Version.. user Super PI 1.5Xs

[TigerDragon666]

how did you got those yellow text? is that c0 or d0

[Zico10101010]

can i overclock the i7 to 4200mhz with xigmatek dark knight reply please.

[xfxinkz]

i dont think so mate

[Cryp666]

Just test it :d every cpu is different

[jimi1765]

you better get noctoua i7 cooler

[jlebesis]

This is Air Cooled yeah?

[music4allchannel]

Hey, what graphics card did you used when you ran 3dmark06

[ffs2k]

Robbaz, i got 3gigs of Kingston DDR3 2000mHz CL-9-9-9-27. Can i use the same settings with that ram? Or maybe run it at 1600mHz and lower the latency to 8-8-8-24?

[Robbaz]

Yeah sure.

[mgsamps]

Now excuse me for being blunt but I thought this video was supposed to show us how to o/clock our i7 not how fast you can press buttons, so why don't you do it at a speed which we can actually see WTF settings you are using? we are not all on Epinephrine as you or Chev Chelios (aka crank) are, Just hold the cam on your screen with the settings longer and explain how some settings effect the resulting cpu speed or memory speed, otherwise there is no point in yr vid.

[Kenjineering]

gday mate, I remember you once telling me that since I have only 1333Mhz DDR3 ram my max OC on a core i7920 will be 3.5ghz.

I see that your ram there is running at 1200 Mhz but you are getting an OC of 4+Ghz. Could you please explain again why i can't do that and what knowledge I am missing :S ... a big ask I know

[Robbaz]

For full effect from your ram you need 1600mhz at 4ghz.

[SimsCreedGuy]

whats the best cpu cooler if i want to OC to 4Ghz?

[matttd9490]

Whats that program your using to test 100% stress on the cores?

[hyrael2]

it's Super PI here

[juggolo]

prime 95 and Linx are good programs

[tehdaza]

1.45v CPU?

That's not gonna last very long :O

[Robbaz]

how comes? :)

[tehdaza]

The max recommended voltage is like 1.375. I dunno, as long as you've got good cooling on your mosfets you might be fine :P

[Robbaz]

Ahh you mean different models :3

[Robbaz]

Motherboards rarely varies in overclock, it's the cpu itself that you need luck with.

[Yytinen]

Is this 24/7 overclocks? Im buying i7 920, 6gigs of corsair dominator and asus p6t mobo (not sure which one of them). I have zalman reserator xt watercooling and if i buy that stuff i would like it to go over 4ghz, so can i use i7 920 over 4ghz with good cooling 24/7 ?

--yytinen

[pbrain69]

i've got a similar system (i7 920, 3x2gig Corsair Dominator 1600 8-8-8-24, Asus Striker Rampage II) i'm using a cheap Siberian Tiger II CPU cooler, i'm gaming for hours at 4GHz no problems (in fact it seems MORE stable than stock clock!?) Crysis at v.high 1920x1200 4xAA no problems (max CPU 50'c, SB 60'c,NB 60'c & Mobo 40'c). i've got the cpu voltage at 1.45, if you're going to buy a new 920, then even better (i've got the original 'hotter' version) you can take it further still.

[Yytinen]

Ok, that sounds good. Now i can buy it ! Thanks for answer.

--yytinen

[Hardscript]

the i7 can go over 4ghz without breaking a sweat.

[Timppapoika]

What kind of voltages do you run for the Core and Uncore?

[coookalo]

i am getting the same one can you like give me a video or something on how?

[Connactt]

robban va heter du på playstation ;)?

[pbrain69]

hello, what hard-drive you using, i've got similar set up but it's way slower loading? cheers

[Robbaz]

standard 7200rpm it's simply speeded up.

[N1mro8]

Although i didnt like the music ;), i love your rig. What kind of camera do you have!

Btw for cooling you use the Mugen2?

[Robbaz]

The first mugen also known as infinity.

[robalm1]

Hej har du nåt benchmark resultat i counter strike source?

[Xclusiv8]

80 Grader? Är inte det lite väl mycket?

[Robbaz]

Inte direkt, inte heller skadligt men man bör hålla sig under det för att livslängden på processorn ska bli längre.

[Xclusiv8]

jojo. Från 10 år till 9.5 LOL

Jag har alltid gått under intrycket om att man ska försöka hålla dem under 60grader i full load. Det är i alla fall vad alla på sweclockers säger :P Jag har en Q6600 som är överklockad till 3.2 Ghz. Så igentligen skulle jag kunna klocka den mer. Sitter på en liknande kylare. Har en Noctua NH-U12P

[Robbaz]

Det är nog också mycket hur mentalt mycket man vågar, har kört 3dmark06 och då kunde det peaka till 95c vilken nästan alltid sätter hjärtat i halsen på mig.

[Xclusiv8]

hahaha.

Hur länge har du kört den här klocken då? Har du haft några problem?

[Robbaz]

Inte än, tror inte det kommer bli några problem heller. Men jag har ju den äldre c0 steppingen, tror folk med d0 kommer vara mycket säkra. Har sett många som fått betydligt bättre resultat än min c0.

[Xclusiv8]

ja det är inte dåligt med 4.2Ghz =) Ska köra upp min Q6600 till 3.5 och se hur det går.

[Robbaz]

Det är väldigt bra för en q6600 dom håller i sig ett tag till.

[dannyKurt]

what are u cooling it with ? air or water cooling?

[Robbaz]

A old infinity/mugen.

[RoboTHUG2]

does it work with WINDOWS XP? answer me, please I have to know it

[Robbaz]

Ofc overclocking works with any os.

[RoboTHUG2]

thanks alot

[Xpayne1]

guys please i need help i'll buy core i7 920 3gb ram GTX260 p6t - X58 ( and ill keep my 580 watt from old pc , so pelae help me! from 2.66ghz can i do 2.8 ghz with 580watt ??????)

[Robbaz]

580watt will be more than enough.

[Xpayne1]

ok thanks bro

[tehdaza]

The i7 920 will automatically clock to about 2.8 Ghz if you have Turbo mode on.

(atleast it does for me.)

[Robbaz]

it's a decent little boost :)

[tehdaza]

I'm just waiting to save up for a nice cooler for my CPU. My system is pretty much the same as yours.

[onemanshowcro]

if you have a old noname power supply i wouldnt use it ...

buy one from BeQuiet! or Corsair

[Leoooonard]

vad har du för cpu kylare? Scythe Katana elr?

[Robbaz]

Mugen/Infinity

[firecos]

Record your shit with a HD PVr n00b that looks like shit

[Robbaz]

So you say that it should hook my dvi port to a adapter or with s-video to a hd-pvr then record my super low resolution bios?

I know how to record my screen in hd don't be a fucking tard.

[Kenjineering]

What OC frequency limit do you recommend with only the stock cooling?

[Robbaz]

As far as you can make it with minor to none vcore increase.

[Kenjineering]

thanks for the reply!

[Robbaz]

Also check temp, since that's the only thing that will hold you back if all other hardware is top notch.

[Kenjineering]

What program shows temp?

so do u run ur comp at 4200Mhz always?

Core i7 920 2.66

DX58SO smackover motherboard

Kingston DDR3 RAM

GTX 280 SLI

Vista 64 bit on a solid state

Nokia N95

[Robbaz]

I'm using coretemp to check tempature, what frequency do your ram have? 1333mhz is limited to 3,5ghz overclock with speedstep/turbo. 1333 / 8x mem multi = 166.5 x 21 = 3,5ghz.

While 1600mhz / 8x mem multi = 200 x 21 = 4,2Ghz.

I'm not saying that 3,5ghz is a bad overclock it's really good.

Yeah i run my computer constantly at 4,2ghz with a infinity/mugen now with two 120mm fans. It keeps it under 80c but alot of people find that to high, never got any issues this far.

[thierryvt]

so far lol, if stuff starts melting inside you won't notice anything in first instance untill your cpu speed starts dropping. my bro had this, he had an oc cpu wich ran to hot but gave no trouble. only after a month or 2 he started noticing that his pc was slowing down and dxdiag was indeed showing lower speed while he did not change anything.

[Duckcuc]

What programs are you using ?

[Robbaz]

super pi, cpuz, rivartuner, core temp and 3dmark06.

[CRAKIZGOOD]

what cam are u using

[CRAKIZGOOD]

cam ?

[Robbaz]

Recorded with a nokia n95.

[CRAKIZGOOD]

omg my vids are also recorded with a n95

i say that red rec light and i was like

impossible i thought i was the only one that used a crappy camera phone for youtube xD

what happend to that other vid about gpu ?

[Robbaz]

Found a pretty bad misspell :P and yeah the n95 is a pretty damn decent :)

[joshua12345676]

lol

[oc5nsli341nforce4]

Nice oc, must be running with after market cooling on that 920.

[Robbaz]

It's a scythe mugen or infinity depending on when and where its was bought.

[oc5nsli341nforce4]

Be careful its like a box of razor blades! One had to get stitches on three fingers due to that thing but its a beast of a heatsink wish it was all copper though.

[Robbaz]

hell it was a push pin 1366 kit for it and i didn't remove the motherboard so i got my fair share of scratches :)

[oc5nsli341nforce4]

Would,t mined getting one but I have three zalman cnps7000b-cu heatsinks that I bought for less than $15 a peace. good deal when on newegg there $33 new.
