    For stability testing I have run several hours of AIDA (which I find raises temps higher than Prime), an hour of prime 12k's, encoded 8gb of video from x264 to avi, and run continuous loops of the Grid 2 benchmark.

    The Grid 2 bench is because I found that was the only thing crashing the machine when I had the offset at 0.07v (bizarre i know).

    I'm now running at 4.7, and all i've done is change the voltage to fixed @ 1.25 rather than use and offset, all the same tests and still stable.

    Temps peaking in the 80's, and the AIDA SinMandel bench seems to get Core0 to hit 92deg.

    I am going to delid when i replace my loop at the weekend.
    OK. Thanks.

    Right, Haswell is new and I want to make sure I'm on the same page with others as I see the same term being used for different things.
    I saw a post where someone said they had to use the Intel ETU for adaptive voltage, other's say offset in bios. Gets confusing after a bit.

    From the Overclockers link in post #130:
    Caveat big, massive, honking, pay attention to this caveat! When using adaptive voltage, the top of the curve isnt necessarily the whole story. ASUS drove this point home when we met and Im doing so now; we all need to do this as a public service to our users and readers. Even though you set 1.25 V as your maximum voltage, under certain very heavy loading conditions (i.e. stress testing), the voltage can and will exceed the maximum you have set. Let me say that again if you stress test using adaptive voltage, even with the maximum set to 1.25 V, the CPU will guaranteed request and receive more voltage than you have told the motherboard to deliver it. Its just the way this works.

    In the ASUS demonstrations, setting a maximum 1.25 V in this scenario and then running something like AIDA64, Prime95, etc any stress testing application designed to stress more than normal loads the CPU requests and gets ~1.36 V. There is nothing you can do about this and it will happen whether you want it to or not. The only way to prevent stress testing programs from pulling extra voltage is to use a manually set voltage, which takes away your CPUs ability to reduce voltage when idle.

    All is not lost though! You probably noticed every time I told you what would happen it went hand in hand with stress testing. Thats because those are the only scenarios that will lead to this behavior. In all other circumstances so far as ASUS can tell, the CPU will cap at the set 1.25 V and never exceed it. Even if youre Folding@Home it should maintain the 1.25 V cap (though those folding at home are under 100% load all the time and Id suggest using a manual voltage for those machines just in case). Likewise, video encoding, audio encoding, compression, rendering any CPU-intensive process, your CPU will maintain the 1.25 V cap.

    So, now that you know the very important caveat, set 1.25 V as your maximum voltage with adaptive voltage, enable C1E and EIST (which throttle your multiplier and voltage when not under load) and go on with your merry life knowing your CPU is as relaxed as it can get when idle.

    but the temps on load in Lynx max 80 AIDA64 max 87 is an issue .....Just guessing can it be thermal paste or it is ok temp for air cooling , i used 2 years old Arctic cool MX-2 , that was really good on Asus p8p67 pro and i5 2500 k...
    Max tmp was 74 on 4.5GHZ and 1.3 vcore and here is just 1.17 and already 80-87 ....

    I got an average cooler Cooler Master V6

    So my question is:
    IS it ok for such a temp on load for 1.17 vcore on average air coller or 2 years old thermal paste can be an issue ?

    Waiting for your advises )
    Thanks to you all )))
    The temps look OK for benching, I wouldn't want to run high 80's for any length of time, but that's me. I get high 80's benching with all custom water so it all depends on the cpu lottery.

    That makes sense.

    So how do you set adaptive on GB boards? I can only see an option for Offset in the BIOS.

    Using GTL? EasyTune? Intel Extreme Tuning Utility (XTU)?

    Does pressing CTRL + F1 do anything to unhide some settings?

    Hi TomazzZ.......welcome to forum.

    Your GFlops in LinX is very low (should be arround 115-120).Setting is OK (no need 50 runs...20 is also OK),but which version you are running?
    Did you run on Win7 SP1?

    If you testing stability with latest AIDA64 3.00,be sure to set Preferences/General....Memory block size minimum 512MB.
    Even 1 GB is better to full stress your memory together with CPU.

    Not good setting I saw in Sin0822 Z87 OC Guide...20 runs finished in less the 5 min......proper 20 LinX runs take 1 hour+

    Prime95 27.9 needs some updates for Haswell. Normally I would trust LinX or IBT only since it tell us the GFlops which shows the efficiency and accuracy of our overclocks. Eg.(sample under water):

    4.4GHz @ 1.25v - 125 GFlops, 85C
    4.5GHz @ 1.3v - 135 GFlops, 90C

    The higher the GFlops, the more performance the overclock yield. So, 1.3v is picked as our preferred vCore.

    That was on win7 SP1 with AVX instruction AND LinX with AVX libraries build 10.3.7.

    On win7 non SP1 OR LinX non AVX, you would get:

    4.5GHz @ 1.15v - 60 GFlops, 60C

    lower GFlops and reduced performance of AVX supported apps and might sometimes get BSOD on routine works.

    Thats why I said the hotter or the more vCore needed, the more stressful the app. Also, the more vdroop (lower load vCore) the more stressful.

    Edit:
    OCCT 4.4.0 (CPU Linpack) is also OK, if you set per pic bellow:



    (untick 85C limit in setting)

    Better to follow Sin's guide than all that ASUS stuff. On the Gigabyte boards Extreme LLC will stop droop but the board is still going to allow some voltage increase with a set vcore.
    If you keep all the "power saving" options on Auto the board will downclock and downvolt just fine at idle speeds because with Haswell voltage regulation is on the cpu.

    FWIW, it looks like MSI provides Adaptive voltage settings in some of their motherboards.
    From the MSI Z87-GD65, Z87-MPOWER and Z87-MPOWER MAX motherboard manuals:
    CPU Core Voltage Mode/ CPU Ring Voltage Mode/ CPU GT Voltage Mode [Auto]
    Selects the control modes for these voltages.
    • [Auto] This setting will be configured automatically by BIOS.
    • [Adaptive Mode] Sets adaptive voltages automatically for optimizing the system performance.
    • [Override Mode] Allows you to set these voltages manually.

    I wonder if some of the higher end Gigabyte motherboards support adaptive cpu voltage control.
    With Gigabyte motherboards, I would definitely follow Sin0822's recommendations.

    Caveat – big, massive, honking, pay attention to this – caveat! When using adaptive voltage, the top of the curve isn’t necessarily the whole story. ASUS drove this point home when we met and I’m doing so now; we all need to do this as a public service to our users and readers. Even though you set 1.25 V as your maximum voltage, under certain very heavy loading conditions (i.e. stress testing), the voltage can and will exceed the maximum you have set. Let me say that again – if you stress test using adaptive voltage, even with the maximum set to 1.25 V, the CPU will – guaranteed – request and receive more voltage than you have told the motherboard to deliver it. It’s just the way this works.

    In the ASUS demonstrations, setting a maximum 1.25 V in this scenario and then running something like AIDA64, Prime95, etc – any stress testing application designed to stress more than normal loads – the CPU requests and gets ~1.36 V. There is nothing you can do about this and it will happen whether you want it to or not. The only way to prevent stress testing programs from pulling extra voltage is to use a manually set voltage, which takes away your CPU’s ability to reduce voltage when idle.

    All is not lost though! You probably noticed every time I told you what would happen it went hand in hand with stress testing. That’s because those are the only scenarios that will lead to this behavior. In all other circumstances so far as ASUS can tell, the CPU will cap at the set 1.25 V and never exceed it. Even if you’re Folding@Home it should maintain the 1.25 V cap (though those folding at home are under 100% load all the time and I’d suggest using a manual voltage for those machines just in case). Likewise, video encoding, audio encoding, compression, rendering – any CPU-intensive process, your CPU will maintain the 1.25 V cap.

    So, now that you know the very important caveat, set 1.25 V as your maximum voltage with adaptive voltage, enable C1E and EIST (which throttle your multiplier and voltage when not under load) and go on with your merry life knowing your CPU is as relaxed as it can get when idle.

    Excellent info! The only time I have see my gigabyte board do something similar to this is when setting offset vcore. At 4.5ghz in bios with vcore set to normal and offset +0.000 I get 1.111v +075v = 1.198ish in windows at light load. Under full load vcore will jump to 1.325. I have tried dropping llc from extreme to turbo and no difference on full load vcore.

    If you keep all the "power saving" options on Auto the board will downclock and downvolt just fine at idle speeds because with Haswell voltage regulation is on the cpu.
    On my z87-OC board I have never been able to get vcore to drop at idle when using fixed vcore. I have left everything on Auto, Ive tried Turbo disabled, c1e enabled, c3 enabled EIST enabled and c6/7 disabled and any other combition I have see floating around on the forms that other say worked for them but has yet to work for me.

    From the MSI Z87-GD65, Z87-MPOWER and Z87-MPOWER MAX motherboard manuals:
    CPU Core Voltage Mode/ CPU Ring Voltage Mode/ CPU GT Voltage Mode [Auto]
    Selects the control modes for these voltages.
    • [Auto] This setting will be configured automatically by BIOS.
    • [Adaptive Mode] Sets adaptive voltages automatically for optimizing the system performance.
    • [Override Mode] Allows you to set these voltages manually.

    I wonder if some of the higher end Gigabyte motherboards support adaptive cpu voltage control.
    With Gigabyte motherboards, I would definitely follow Sin0822's recommendations.

    z87-OC only has fixed vcore and offset vcore. I have never been able to get voltage to drop at idle with fixed vcore. Offset vcore will overvolt at full load.
