Icore7 OC

Just upgraded my comp with a icore7 920. Was looking for some advice and info on over clocking the cpu. I have never tried to OC a cpu before. Was wondering what's the best way to go about it. Should I get a bigger heat sink and fan? If so can someone recommend a good heatsink for the I7?As for water cooling, is it hard to setup/maintain? It sounds risky having water run around your comp.Icore7 OC
This is a custom build right? Anyway, yes an aftermarket heatsink and aftermarket thermal paste are a must. I would recommend the Scythe Mugen 2. It's one of the best air coolers out there and at a great price. For your paste I would recommend a high quality ceramic. Arctic Cooling MX-3 or GELID GC-Extreme or GC-2.Icore7 OC
I bet you haven't even tried to use that processor to full potential, you just hear it can overclock so you want to overclock for no purpose. Anyway, for beginners, just increase the multiplier by a bit, or if your mobo or CPU don't allow that, increase the frequency from the standard 133 to 150 for example. Also, don't touch the voltages and fans. The stock cooler should be fine up to 3.8, at least that is with my Phenom II 955.

It's still being shipped from Newegg to my house. And yes, I'm over clocking it for no particular reason. I'm just doing it because I can... Don't tell me you have a purpose because from what I read there is no graphics card that can push the current processors to there limits. Why do people sup up their cars when the speed limit is 65 mph on the highway... Same reason.

Wow, hold on there. Do you even know what you're talking about? You realize that the i7 920 has a stock clock speed of 2.6 ghz, right? Opposed to the 955's 3.2?

I was thinking of getting another one to do SLI. I had planned on getting one of the newer video cards but figured it be better to wait for the new DX11 cards. So a second 8800 GT will have to hold me over for now.

Yeah, it would probably take water cooling to get that chip up to those speeds.

I was comparing how much I overclocked the CPU, and since our CPUs overclock similar and heat similar, I was saying he could expect a max 3.8~4.0 on stock cooling. What the hell do stock speeds matter now? Think before you start flaming.

Really, no one in this thread knows what they are talking about. I'm out, cya.
3.8 on a core i7 this late into it's release is pretty common, especially a D0 stepping chip(4.0Ghz is very common with those). WCing isn't necessary to obtain these speeds either. Granted using stock cooling to get a core i7 to 3.8 Ghz is stretching it, going by Slig0's calculations, 3.2 > 3.8 = 600mhz so a 2.6 core i7 + 600mhz = 3.2 Ghz with stock cooling(Extreme Edition Speeds). I can assure you, if you are overclocking for no apparent reason and running sli with 8800GT's you wouldn't need to go past 3.4Ghz - 3.6Ghz since those cards won't be bottle necked by the CPU. If you had 2x295's or 2x285's then overclocking higher is more practical.

I was planning on trying to get to 3.5. Would that be possible with the stock heatsink? With just air is it possible to keep the CPU temps around 60-65 at max load at around that speed?
Just finish the upgrade. I ended up spending a lot more than I had planned.I ended up getting a new case. SLI on my old Lian Li Mid Tower was way too hot. Only had 80 mm fans in it. Back side of the case was almost hot enough to burn my hand when I touch it after playing The Witcher for a few hours. So for those of you planning on doing SLI or perhaps getting the new cards with 2 GPUs watch out. Old cases aren't enough to keep them cool.So I probably freaked out a bit and over did it when I upgraded. I upgraded my case to a Cooler Master 840.http://www.newegg.com/Product/Product.aspx?Item=N82E16811119187I'm old school so I hate anything that has an LED or window.I also went the newb way with water cooling my cpu. I bought aCORSAIR CWCH50 Water Coole. http://www.newegg.com/Product/Product.aspx?Item=N82E16835181009I thought it be good to buy a kit just to see how water cooling works. I'm planning to create my own for the video cards soon. So with this current setup I overclocked the I7 920 I recently bought to 3.6.Running at max load with Prime95 I never got over 69 C. Was wondering what people get with just running air? I'm guessing there are probably a lot of after market air heatsinks that can beat this setup. The corsair water cooling setup seemed a bit small and is probably no where near as good as a real water cooling setup.Edit: Forgot to mention that I bought an extra 8800 GT to run SLI. I can't imagine how hot running the newer cards in SLI would be.
The corsair is good enough for lazy people like me.

69 C is highest core temp. Core 0 for me is around 3-4 C hotter than the other 3 cores.
Something is odd about the temps I'm getting. If I run at stocks speed at max load my core temps reach up to 63 C (2.66GHz). I overclock to 3.2 GHz and run at max load and temps go up to 68 C. I run at 3.7 GHz with max load and it only goes up 2 C to 70 C. I'm using Core Temp 0.99.5. Over clocking a full 1 GHz over stock is only raising my cores around 7 C. These reading come from running prime95 for at least a half an hour. This just doesn't seem right to me. How are the temps for everyone else?

is the voltage in the bios set to auto?if it is,then it is probably supplying a lot more voltage than what the cpu really needs,hence creating more heat
There have been guides upon guides on how to overclock an i7 considering they are little bit different. Unfortunately you can't increase the multiplier because the i7 920 has a locked multiplier, so you have to raise the BCLK and so on and so forth (I am lazy to write directions). A guide that incompasses almost every option is found here.

I left it at the default auto for stock and at 3.2 GHz. I check the voltage with CPUZ and it showed it at only 1.1 V when running prime95 at both stock and 3.2 GHz. I did change it manually to 1.411 when overclocking it at 3.6 and 3.7 GHz. The jump in voltage didn't change my temps by much. I'm starting to wonder if something else is heating up my cpu. It seems to never go below 40 C at idle. I have a big case with good air flow. My only guess is because I'm using a water cooler the board doesn't get the air from the fan on a heat sink. I'm not sure, I'm just guessing right now but, does the motherboard need the heatsink to cool other parts on the board? Would using a North Bridge Cooler do anything for the CPU or is that completely separate?

Errr... Idle temps don't particularly increase or decrease unless you turn off the CPU power saving functions. The most important thing is your load temp.
