Looking for some advice/help with overclocking an i7-2700k

post #1 of 22
Thread Starter 
Hi guys,

I have had my system now for around a year and, up until now, I haven't really had any issues with it at all. I am running games of High/Ultra and, while I was at University up until August, my 3d work was going fine and my rendering times were low enough.
However, I have noticed that with some of the newer games, such as Addons for Battlefield 3 and, recently, ArmA II (Day Z) i am experiencing some delay. I have had a read up on the Day Z issues and, while it mainly comes down to how inefficient the Engine is, I'd still like to try to overclock my CPU somewhat, considering how CPU dependent it is.

So, I have made this post to get some advice and, ideally, someone to guide me through the process. Obviously, I'd like you to all look at the spec I list below to confirm to me whether or not overclocking is possible, but I believe it to be so.

Case COOLERMASTER CM690 MKII ADVANCED CASE
Processor (CPU) Intel® Core™i7-2700k Quad Core (3.50GHz, 8MB Cache) + HD Graphics
Motherboard ASUS® P8Z68-V LX: USB 3.0, SATA 6GBs, ATI®CrossFireX
Memory (RAM) 16GB SAMSUNG DUAL-DDR3 1333MHz (4 X 4GB)
Graphics Card 1GB NVIDIA GEFORCE GTX 560 Ti - 2 DVI,HDMI,VGA - 3D Vision Ready
Power Supply CORSAIR 650W ENTHUSIAST SERIES™ TX650 V2-80 PLUS® BRONZE
Processor Cooling TITAN FENRIR EVO EXTREME HEATPIPE CPU COOLER

I appreciate all the help you can give me and I am here to answer any questions also!

Thank you very much

Oliver

Morning,

Yes, overclocking is possible, but we need to know what cooling you have on your CPU. Did you get an aftermarket cooler or are you using the one that came with the processor?

Morning,

I did mention it in the OP, but I'll list it below for you

Processor Cooling TITAN FENRIR EVO EXTREME HEATPIPE CPU COOLER

Hope that helps

Thanks

There is a Sandy Bridge overclocking guide in this subforum, which you should be able to locate with a search -- it might be worth while to read through this first to get familiar with the steps involved; it should eliminate a lot of the guesswork later on.

Some applications you'll want to download and install for the task: RealTemp 3.70 (or CoreTemp, an alternative), CPU-Z 1.58, Prime95 v27.7.

Welcome to the forums, by the way.

Hey Stalhart,

Thanks very much for the reply. I see you have got the same CPU, have you had any good results with it?

I have all of those applications downloaded as I remembered using them the last time I overclocked, which was on a Q660!

I will check the forum posts out, However, the main reason I posted here, was the same reason I made a similar post (under a different username 4-5 years ag) regarding the old CPU. I Managed to find a guy who talked me through the entirety of the overclock process for my CPU, he helped me with the voltages etc and helped me get them stable. I know it sounds lazy and incredibly 'noob' of me to ask for such, but you know, one much look!

Do you have any idea whether you could maybe talk me through it? I obviously understand if you cannot.

I am going to check the posts you recommended now smile.gif

Sure, we can work together on this, either here or PM, your preference. I'm extremely happy with the 2700K so far. Everything is stable and running beautifully at the moment.*

Our motherboards are different, but I can pull down the manual for yours later tonight to have a look.

* well, except for this Windows 7 issue of an inability to cache icons in the start menu I've been struggling with mad.gif

Stahlart has began helping me guys,

However, would be great if anyone else could give me an advice or guides, as he has expressed that his method might not be the way many would go.

Please let me know smile.gif

How high were you looking to go? That motherboard has somewhat limited overclocking options, but it should pretty easily get that chip to 4.5 or 4.6. For a quick start you can go in the BIOS and change the Turbo Multipliers* to something reasonable like 44, leave everything else on Auto, and then boot into Windows and run Prime95 or IntelBurnTest while watching the volts (with CPU-Z) and temps (with Coretemp or Realtemp). As long as they are reasonable (around 1.35V and under 80C) then you are pretty much set to continue stability testing. If the volts are higher than that, or you decide you want to push higher, you'll need to do some more work in the BIOS. but I'd try that first and then post back with the results.

* In the BIOS go to the AI Tweaker page, change the AI Overclock Tuner to Manual, change the Turbo Ratio to By Per Core, change the Ratio Mode to Syncronization, and then change the 2/3/4 Core Ratio Limit to 44.

To elaborate, it's positive versus negative offset; I'm using negative (-0.020V).

Hi,

I found everything you mentioned except "Ratio Mode", I couldn't find where to change that, so the 1/2/3/4 core numbers stuck on Auto.

Do you know the specific name of the option?

Edit: I am not looking to go high at all. I don't want to do damage, but I know I can get more out of my system than the stock 3.5ghz, I have no doubt about that at all.
