Hawk,
 
What is your cooling? Power supply? What is your overclocking goal?

Thank you so much for this, this really helped me out as I am, as many others are too, quite new to overclocking.
I've never gotten a CPU this high before :P

This is what I got so far: http://flayer.fisknylle.se/datorn/orig/clock.jpg

Any suggestions about what I may change to get it a little higher?

And again, thanks.

Just curious...the temps listed in E-LEET are the current temps, so with your stress test finished, are those your idle temps? LinX is a quick test and will push your cpu to the max, and it is used by many on these boards. Prime95 is also a good test for stability, but not quite as tough on the cpu, and if your system can get through 12 hours of Prime95...that is good. With LinX make sure you select 'All' for memory and run it for 20, it takes about 40 minutes. Core Temp or CUPID Hardware Monitor are good applications to have running while stress testing, because they will record and save the highest CPU and Core temps during the test.

Yes, those values was my idle temps, it sank almost instantly after SuperPI finished, so I never got the temps on pic.
The max temp it ran up to under the SuperPI test was around 64°C.
The thing I'm worried about is that when I ran 3DmarkVantage, my CPU hit 92°C! That can't be good, so I canceled the benchmark.
Even if my Corsair H50 Hydro cools alot better then the stock fan, it's not enough to cool my CPU when it's runnin 3DMark.
The only way I see it, is to "clock down"(don't really know the word here) my CPU a bit, and lower the voltages a bit.
Or is there another way? :)

EDIT:
Ok, so I ran LinX, but after 2 "loops"(around 3 minutes) I didn't dare to continue, one of my cores got 93°C hot.
And yet I "clocked down" my CPU to 3,8 GHz instead of 4,2. It got more stable at 3,8 tho :)
But, I don't think I should continue overclocking with my current CPU cooler, the CPU tend to get too hot.
And yet, a friend of mine have his Intel core i7 860 @ 4,2 GHz, and as far as I know its stable, and he uses the exact CPU cooler as I do, and his temperature seems not to be too high at load.

Flayer...I think you should start a new thread over at the P55 section of these forums. There has been a lot of discussion recently about the H50 and how to set up the fans and your set up is, for the most part, the same as most people are using. If and when you post include all your current settings, cpu and memory, and how you have your H50 fan(s) connected, and how you have your pump connected. You should be able to get a lot of help there, because your temps are out of control.

Ok, thank you for your help dennisburke, I'll post a thread over there with my current "everything" ^^
EDIT:
Here's the thread: http://forums.evga.com/tm.aspx?high=&m=252657&mpage=1#252657

 Hi guys. I'm new here, and I have two problems.
First, I'm french, and I don't know if it is curable.
Second is, I have a EVGA P55FTW for 2 weeks, and I think I need advices to overclock my i7 860.
I don't really know what PCH, CPU PLL and CPU VTT  are, and I don't know what are max safe settings for these voltages.
Thanks (and sorry for my language)

Greetings!

These are my specs:
P55 Classified 200
i7 860
4x2GB GSkill PI - 2200MHz CL7
GTX216 Core216 SC
Seasonic X750 / Enermax Modu82+ 525W

Everything is going fine with my system, except for a whining noise coming from somewhere around the PWM area. It drove me insane when everything was stock. Some kind of coil noise (but what coil noise is there when you're dealing with a digital PWM), buzzing or something.
I changed the PSU to a Seasonic X750 and the stock cooler on the CPU to a Venomous X.
Got it running @ 4 GHz with no problems.
20x200 MHz, 1.33V Vcore 1.3Vtt, RAM @ CL7, 1600MHz
Now, that sound is gone, but a new one is present. A very high pitched whine, not loud, but definitely audible. It is just driving me nuts.
Is this normal? What should I do? Change the switching frequency to other than auto?

Later edit : I loaded the setup defaults and disabled C1E and all those things. The initial sound is gone, but the high pitched noise when overclocking is still there.

So yeah, I'd been struggling all night trying to get a stable overclock. Tried voltage changes, multiplier, nothing would let me get through even 1 hyperpi run.

Looked at the BIOS version I had installed, dated 09/09/09....omg, that's old. Just flashed it with A59, and its stable @ 4.2

Vcore @ 1.35
Think I'll play with the voltage a bit to see where it gets unstable now. Highest temps are at 69c with 8 threads going.
 
On water.

hey'veryone :D
actually planning to o/c my i5 750 on a evga55micro

first post of this thread say "disabling intel E-SATE" for stability reasons...

there is a video i found on youtube:
http://www.youtube.com/watch?v=ekQG_qonjvo

this guy use speedstep and turboboost for low consomption in idl state (1.5ghz), and btw keep getting high frequencies (4ghz) when its needed

what do you guys think about this, is that a way that i have to do my o/c ?

ps: im pretty sure hes on a gygabyte or sum**** like that, am i able to do this trick on evgasmobo?

well, let me see if ive understand correct:

when i set my cpu frequencies using turbo mode (ex: 3.6ghz), turbo mode go over my o/c settings.

btw is there a way to cap/limit that turbo? coz i already own a toaster in my kitchen...
for ex: BaseCLK o/c @ 2.8ghz, and when turbomode cap cpu goes to 3.6ghz (and no further).....is that qpi ratio im talking about?

i can reformulate lol


/edit ok lol i can choose what multiplier my turbo is at (in ur case x26 when base bus speed is at 20)
nice mon' thanks a lot / all hai to germany lol

It's not possible to work with multi 26x 4 cores.
Multi 24x is only for two cores (750)
Multi 26x is for 860/870 (only one core)

The i7 750 used the turbo Multis like this: 
1 Core: 3,20 GHz
2 Cores: 3,20 GHz
3 Cores: 2,80 GHz
4 Cores: 2,80 GHz

It's more energy efficient to use the Turbo with a BLCK of 160.
so you'll got 3,2 for all 4 cores, with turbo (2 cores) up to 3.84 GHz.
And of course, C1E / speedstep is still enabled.

Or you try it without the turbo mode.
Then the most people like a BLCK of 200 with the base multi x20 = 4 GHz all cores.
It's also possible to use C1E and speedstep, but's not so easy to get it stable. 

thx dozer, thx dennis,

i goota give you two some feedbacks in 10days for now lol

160 BLCK looks like the better i have to do, keeping turbo is good as i see, as my memory will works at 1600.

When overclocking it's ok to leave VDroop and C-STATE enabled up to 3.8GHz (20 x 190MHz).

Does that just apply to the 750?  Or should an 860 work like that as well?  These recent posts have gotten me trying OC'ing again and I'm in the middle of LinX right now with the 160xturbo boost setup.  The only thing I've not turned back on yet is C-state and vdroop.  One of them, I suspect vdroop, was causing blue screens trying to boot into windows.  I'm suspecting this means I need more vcore is all.  I had is set to 1.21 and even 1.22 but with vdroop off e-leet now shows at 1.26 under load.  Vtt is still showing the 1.17 I have it set at.

 
I have not had any problems leaving VDroop and C-STATE enabled with my i5 at 3.8GHz (VCore_1.275V...VTT_1.20V). At 160 I'm now using VCore_1.20V...VTT_1.125V. Your voltages look reasonable to me, but your dealing with 8GB of performance memory so mayby you should try a VTT of 1.20V, or lossen your timings, or try a command rate of 2, or try working with 4GB of memory and see how that does.

Yep still BSOD with cstate on and vcore jacked up.  I get apc_index_mismatch so I think I'm going to try this with cstate left off.  Who needs power management anyway lol.
 
EDIT: Hmm actually is leaving c-state off sabatoging attempts to use turbomode/speedstep?  For some reason I'm thinking c-state is needed so that unused cores can be turned off and the speed cranked up?

So I found something new last night, I've always had C1E set to off, it defaults to that in the A51 BIOS.  If I turn BOTH c-state and C1E on, I can boot/etc.  So now I'm starting to wonder if my particular chip is biting me in the ass.  It's a retail SKU part, (i.e. stepping etc.) however the actual chip is an engineering sample (as per e-leet).  I got it from an old co-worker at Intel and it's what they call a promo part.  It's supposed to be the retail item but just not labeled as such.  The serial number is much lower than anything in the overclocking list here.  Like I said though you can look up the sku number on it at the Intel site and it shows it as the current retail version. 

At this point I think I'm just going to wait till I get my new case for improved coolign and just turn off the speedstep/etc. and push for a higher constant overclock.  The problem I had with that before was not being able to get the hot air out fast enough to keep temps decent.  If I get some time over the weekend though I might try doing some stability testing on that O'clock with cstate & c1E turned on. 

The one cpu driven game I was looking for improvement in didn't see as much as I expected.........Flightsim X.  I gained about 6fps (from about 35 to 41).  That was going from the default turbo running about 3.3 to 3.4 to the 160 bclock with turbo on and hitting 3.9ghz on one core, 3.8 on two.  I might be getting hit on the video card now though (since before with a straight OC to 3.8 I would see 10fps diff) because I installed some high res textures since last time I tried to OC and set up the nHancer utility to jack up image quality.

Nope HT does not help with FSX, it does not recognize or use HT cores according to the various flightsim forum tweaking guides I've read.  It IS multi-threaded however and will use real physical cores but still uses mostly 1 core for the primary functions.  Other misc. stuff is offloaded to extra cores if they're available. 

Yeah I know HT can generate extra heat.  If I turn it off and clock to 3.8 I get similar temps to you, if I turn it on I can add about 10C and then shortly into testing either it crashes or I decide it's too high and shut it off.  Because I use the rig for photo/video editing as well I want to leave HT on though.  So that means either a lower OC right now or new case with better cooling for a higher OC once I get the case.  Right now all that happens is my Noctua floods the area around the cpu in the case with hot air that I can't get rid of fast enough due to the case being a much older design.

I'm curious, do you have C1E enabled as well?  Interesting note about the odd multiplier voltage.
