Intel I5 4670k First Time Desktop Overclocker, lowered expectations edition

Hey guys, I'm brand new to the Overclock.net community and I'm currently running a XTU stress test on my desktop as I write this!

Foreword: I'm creating this thread with the hopes that I can have active resources (You guys) which I can consult to avoid pitfalls and establish realistic expectations for my build.

Bringing you up to speed now

After reading a few forums On Overclock.net and Overclockers.com and watching some handy guides like Linustechtips haswell guide, and Sandcrackas Guide On linus I finally felt sort of ready to begin my overclocking.

First thing I did was to to test my 4670K's overclocking potential via 46x multipliers and 1.2V Vcore settings to see where my CPU falls on the bell curve. RAM set manually to 1.5v lowered to 1333mhz, My system went into bios, showed good temps so I proceeded to boot. Windows began to boot, but then crashed giving me a WHEA uncorrectable error once I hit Windows 8.1 app screen. So it appears I may have an below average, or average chip at best.

So I then proceeded to lower my multipliers to 44 @ 1.2V, VCCIN voltage to 2.0V, Ram @ 1.5v 1333mhz, XTU stress test ran for about an 1-1 1/2 hours before crashing, so no dice.

Bringing me to where I am currently, I changed the Vcore to 1.25 and left the rest of the settings as they were. I'm currently 2 hours into my XTU stress test @ 4.41 ghz, according to HW monitor, my CPU core temperatures are bouncing values between 45C and 60C. Package seems to stay between 50C and 60C.

I'm slightly worried about my temperature variations, should I reapply my thermal? I used the plastic bag method to spread Antec Formula 6, but I could go back and do the Razer Blade method. If these variations are fairly normal during these stress tests I'm going to continue to just up the multipliers and voltage and test for stability. This is where community help comes in, as I know there are more values I need to work with. Any tips or recommendations for my next step at this point will be very much appreciated.

It seemed extremely stable so I wanted to step up to a 4.6ghz OC, Not sure if my chip just isn't that great or if I'm doing something wrong because I'm currently running 1.33V Vcore at 4.6ghz with temps from 55C-74C, averaging around 65C. small note I set my Ram to 1866, so that may be lowering my stability. I was unstable after half an hour at 1.32V.

These are the kinds of volts I saw needed to run the 4770k at those speeds, however the 4770k requires more power for Hyper Threading if I'm correct.

Edit: I managed to step back down to 4.5 at 1.25v, so I may have messed something up before as there is no way I need almost a full volt (1.25-1.33, 0.8V) to get from 4.5 to 4.6

I had the same issue, my i5 3570K required more than 1.36v for a 4.7 GHz overclock (1.248V on 4.5), this huge fluctuation in required voltage is normal, all CPU's have different required voltages for stable overclocks. It is quite common to require a big jump in voltage such as what you specified before when going over 4.5 GHz.

Thanks Ben, that alleviated some of my concerns. However, what about my temps, do those variances and general temps seem normal for haswell on a 240mm closed loop liquid cooler? (If you've had any experience/knowledge with haswell)

So I just realized I didn't adjust my CPU VCCIN voltage, it was set to Auto. I'm going to try to pull 4.6ghz @ 1.3V with the VCCIN voltage set to 1.9V.
I'll also need to try to pull up my cache after to try for the 1:1 ratio (or close to)... Which is funny I say that, because I don't even know why it's important to have the Core frequency and cache frequency as close as possible. Common sense tells me the processes work in tandem, and the closer the frequencies the better the performance as the system can pull references from memory quicker and keep up with the speed of the core?

So I stopped my XTU test this morning after 10 hours as it's probably a good enough indicator.

My clock was 4.6ghz @ 1.32V Vcore, 1.9V VCCIN, Cache 3.8ghz (Auto)
Temperatures Averaged between 60-65c, peaking at 70C-72C

My original attempts for a 1:1 at 1.3V for the cache failed after one hour of stress testing with XTU.
I'm now attempting to bring my Cache Speed to 4.5ghz @ 1.3V to test for stability.

Hello there ive had a good bit of hands on overclocking with haswells. For one you don't really need to have the cache ratio at 1:1 ratio unless you have a golden chip or your using some type of software that benefits from it which I personaly only know of several and its very minor biggrin.gif

Also good testing...10 hours of xtu is usually 99% solid and you can always add a notch or two for extra peace of mind.

Other than that everything looks good! thumb.gif

Also member to purchase the intel tuning plan if you haven't already http://click.intel.com/tuningplan/

And if you evern want to check out the delid section...delidding will allow you to get into the 1.4-1.5v range biggrin.gif:D

Don't do this, go back to haswell 101 (darkwizzie's haswell overclocking thread here) and don't even think about going over ~1.15v on ring/cache until you're at max stable core multiplier. 33x cache/uncore is useful for tweaking too to avoid turbo on it

likewise, don't throw too much vcore or vrin, only use what you need

Thanks I'll look into his threads, Vring doesn't affect video editing performace etc too much then? I've heard you always want to keep your Ring ratio as close to 1:1 as possible, within 100-300 mhz optimally. There's honestly so little information about the Ring/cache voltage on any overclocking threads/resources.

Edit: Ok this is probably one of the better guides I've seen, I'll try to use his guide as my reference now. He seems to actually explain the benefits/drawbacks of each feature instead of just promoting balls to the walls on everything (which seems to be the norm for what I've seen).

Ok, I'm a little worried now, I went back to optimized defaults to just clear out the settings and start back from where I was stable before. Now, I've set everything back. including my Sync All Cores mode to 46. Yet somehow according to XTU, while core voltage is "static" it's responding adaptively, without starting the stress test XTU is showing my CPU frequency at 800-900mhz and one active core (Lowest power settings). When I have manually set all the cores to sync at 46x multiplier, why is it doing this?

Besides that my Uncore is set manually to 3.8ghz (Stock Turbo) and I'm 40 minutes into a 4.6ghz stress test @ 1.31 Vcore

Edit: Stable there

However, I found this video while I was looking around for resources and it's a decent guide to overclocking with an ASUS board. After following the adaptive steps defined there, I'm now trying for 4.6ghz @ 1.29, 3.8 Uncore auto, and 1666mhz ram, since XTU can handle adaptive modes without artificially applying more voltages so my fingers are crossed.

Stable: 4.6ghz @ 1.29v Vcore stopped after 8 hours XTU. While gaming/photoshop/Cyblerlink video editing, CPU temps never exceeded 52C
