    Default First time overclocker, needs help with basic overclock.

    Ok, im new to the overclocking scene so please go easy on me.
    So my system is as below. After much tweaking, i WAS able to get my system stable with a cpu voltage of 1.205 and all 4 core turbo multipliers at 42. (I.e 4.2 on all cores while at 100%).
    With my setup, this resulting in an average temp of 74 degrees celcius while running IBT 2.54 in maximum stress level, 8 threads and under Xtreme stress mode for stability testing.

    Problem is, i then tried to raise my memory from 1333, to 1866 (which it is rated at). After numerous BSOD's, i gave up as i could not maintain stability.

    The problem now is that i cannot even raise the CPU at all without it getting far too hot (even though i have returned the ram to 1333).

    I reset all settings to default and then changed my cpu voltage to 1.205 and turbo multiplier to 42. Now under IBT using the same settings the cores reach 100 degrees very quickly and i am forced to hard reboot as the system locks up quite quickly.

    Even under default settings with max turbo 37 for 4 cores, IBT now causes CPU temps of up to 81 degrees Celcius, :( , where as prior to trying to modify the ram it would max out at 72 degrees Celcius while on default settings (no OC).

    I am looking at adding a second fan soon to allow me a push/pull setup, but for the mean time, does anyone have any advice as to bios settings/a template i can use to obtain a stable 4.2, 4 core turbo speed on my 4770K?

    Thanks

    Naw, we love to give new members a hard time.

    BTW, welcome to the forum.

    Check out HARDOCP - Power, Overclocking, Conclusions - Intel Haswell i7-4770K IPC and Overclocking Review, where they say:
    Haswell Tips and Tricks

    There are a few things that you can do to possibly better your Haswell overclocking. The first thing to consider is simply a better cooling solution if you do not already have one. While the physical CPU socket has changed again, Intel has stayed smart and kept the cooler mounting hardware the same as it has been for a while now. LGA 1155, LGA 1156, and LGA 2011 spec coolers will work fine with LGA 1150. A huge Thermalright tower with 120mm push/pull fans or even better push/pull fans is going to likely be required to get enthusiast-grade stability in the 4.3GHz range. Beyond that, I think my first pick would be the Corsair H100i. Past those choices you are getting into spending some very serious money for cooling solutions like the Koolance Exos 2 we use for testing or even if you are DIYing the loop yourself.

    I hope that I am being totally over-conservative on the cooling issue. Please keep in mind that I have only had the experience of using a single 4770K, but have had plenty of communication with ASUS, and ASUS has been extremely serious about getting a good motherboard launch with Haswell. I have never seen a company put so many reasons into the enthusiast side of a processor launch before. I tend to believe that ASUS exactly correct in what its people are communicating to me. Again, retail purchased Haswell processors and our readers sounding off in our Intel subforum will bore this out.

    The second thing to consider is overclocking per core, if you motherboard supports that, which both the ASUS Z87-A and Z87-Deluxe do in both BIOS and desktop software. (The new AI Suite III software from ASUS is quite nice as well.) No, we did not show per-core OCing in this review, but it works. We do not show this because it adds more variables with trying to get repeatable benchmarks depending on how you are using the system. But, if you are simply wanting to get higher clocks out of your Haswell but are heat limited this should work for you. Start with core 1 and then scale the multiplier for each core down from there; 46, 45, 44, 43. This will allow you better performance in applications that are generally not CPU dependent or widely thread aware but benefit from high CPU clocks, like games.

    Turning off HyperThreading on our i7-4770K helped us out with core temperatures in a big way. This is probably the single biggest thing you can do to cool off your Haswell 4770K. Turning off HyperThreading will knock a quick 5C to 8C off your individual core temperatures in our experience under high overclocks. Doing this hurts the performance of your processor, possibly a lot, possibly a little, depending on your application. To throw some quick numbers at you, when turning off HyperThreading on our 4770K running at 4.8GHz we saw: Cinebench scores decrease by over 20%, POV-Ray render times increase by 10%, Handbrake encode times increase over 7%, Lost Planet low resolution framerates decrease by 20%, and Metro Last Light low resolutions framerates decrease by 25%. Turning HyperThreading off in our high resolution / graphically intensive game benchmarks, we saw Lost Planet impacted less than 1%, and Metro: Last Light impacted less than 2.5%. So if you are using your 4770K with HyperThreading for workstation applications, a Torrent encode farm, or to play games on a 1024x768 CRT, then you will likely want to leave HyperThreading turned on. If you are using it for "modern" gaming, turning off HyperThreading to give you a better CPU overclock will likely benefit you more than losing CPU cycles with HT turned on.

    Lastly, and a bit more on the [H]ard side of things, you can always get the razor blades out and pop the top on the thing. Folks that have successfully de-lidded their Ivy Bridge processors have seen temp drops across all cores of 5C or better, many times much much better. SonDa5 in our forums documented a 12C decrease, and took awesome pictures to show you the process. Obviously this comes with the risk of totally fubarring your CPU.
    Be sure to go to their web page and click on the links in their summary.
    It might help if you clear your CMOS and then go back and re-enter your settings.

    Default Re: First time overclocker, needs help with basic overclock.

    Since im only trying to overclock to 4.2 (since im on air cooling), wouldnt disabling hyperthreading just in effect negate any gains i make since it is only a "small" overclock?

    Since i just purchased the pc, (bought all parts at same time), i went back to the store which suggested i try a re-paste since hitting 100 deg Celcius (even if only once), could have affected the paste performance. If that doesnt work they seem to be happy and willing to replace the CPU for me.

    Its just scary as i went from 50's on load on stock clock to 70's on load on stock with higher spikes 0.o , so i am hoping its just the paste rather than me having cooked the CPU. Though i thought this would be highly unlikely since i never used any excessive clock speeds or voltages???

    You need to take a logical approach when troubleshooting any problem.
    You can often save yourself a lot of time and grief by trying the simple things first.
    The first thing that I would do is to verify that your cpu heatsink is secure.
    Problem is, i then tried to raise my memory from 1333, to 1866 (which it is rated at). After numerous BSOD's, i gave up as i could not maintain stability.
    You didn't specify which specific settings you changed when you went from 1333MHz directly to 1866MHz.
    Are you aware of the possible problems when you use the adaptive voltage option when you are running some extreme stress testing programs? Many users have had excellent results when they O/C using the techniques in the 3 Step Guide to Overclock Your i7 / i5 Haswell Platform | Overclockers
    The graphic at the end of this post helps to explain the possible heat and voltage problems when using adaptive voltage and doing strenuous stress testing.

    Clearing the CMOS is quick and easy to do and this can often fix many problems.
    I suggest that you retest your system with your original settings first. after clearing your CMOS and see what your temperatures are.
    You could then leave your cpu at stock speeds and then see if your memory can overclock to 1600MHz and test for stability.
    If your system is stable at 1600MHz, see if your memory is stable at 1866MHz.

    It's up to you when you want to check the thermal grease.
    When you do, you will need to thoroughly clean off all the old TIM and then reapply new TIM.
    Sometimes it's helpful to post a screen-shot of your overclock settings by pressing F12 which will save a screen image of your settings to a usb drive before you boot into windows.

    There is a lot of excellent information in the Haswell Overclocking Guides / Results thread, but it's a very long thread.

    To prevent errors we need to be able to quickly check your detailed hardware list from any of your posts and you can do this by following the following directions:
