    Default Is it safe to run 3770k @ 4.4ghtz everyday?

    Recently completed my 1st build and have attempted my first overclocks! Like many 1st timers i'm looking for some feedback & reassurance from some more experienced users! I ve spent a very long time reading articles and guides and hopefully now have a stable everyday overclock? System is Asrock z68 extreme4 (L2.31A beta bios), 3770k, 16gb Kingston xmp 1600htz, 120 OCZ vertex3 ssd, h70 core with 2x sp120 fans (exhaust), 2 front mounted 12" fans (intake), 2 top mounted 14" fans (exhaust) lamptron fc10 controller. At low load I'm getting on average low 30C's @ 0.86 volts. I recently stressed tested for over 8 hours on occt and had max temp of 60C and max core voltage 1.080v. I'm using core temp & cpuz to monitor also. Is this a safe stable overclock? Or will running it as a daily be a bad idea? I'm running case fans @ less than 3/4 output so more cooling is available. Any comments advice/appreciated!

    As long as you are running it cool, you'll be fine!
    ...and yeah at around 60C, no need to worry at all.

    Thanks for your feedback chaps! I ve been encouraged and have tinkered further' I now have a seemingly steady overclock at 4.6ghts but i'm not sure where I can take it now?? offset +0.005v, turbo voltage +0.004v, cpu llc lv3 (50%). Been running prime 95 now 2.5 hours and no issues max temp @70C (core temp) core voltage (cpu-z) 1.120v. Any suggestions on improvement again most welcome

    I'm surprised (and skeptical) that you are running at a constant 4.4GHz, with a varying voltage as low as 0.86V. You must have SpeedStep enabled. Your max temp and voltage, 60C and 1.080V, are excellent, or I should say very amazing for an i7-3770K, with the CPU cooler you have (very good, but not excellent.)

    CPU-Z does not show the actual core speed over time, or reads it fast enough, it stays at the highest multiplier setting (I happen to use 44 too), but I have SpeedStep enabled, and other monitoring programs (HWiNFO64, AXTU) show the multiplier drop to 16, as it normally does with SpeedStep enabled. Your board has AXTU available, give that a try for a "second opinion".

    I would also check your CPU and core temperatures with another utility. IMO, given what I have seen, CoreTemp temperature readings are lower than reality, since it uses a maximum CPU temperature in its temperature calculations that is incorrect.

    I've had the latest version of CPU-Z running for over five minutes, and the "Core Speed" never dropped below 4400 MHz, while the Vcore changed from ~0.775V to ~1.20v (Vcore set to Auto). Meanwhile, HWiNFO64 or AXTU show the core speeds dropping to 1600MHz, as they should with SpeedStep enabled.

    IMO, using SpeedStep is a good option, since a CPU is not running flat out all the time, while doing nothing, but speeds up as soon as the load increases. My point is you likely are not running your CPU at a constant 4.4GHz, if you are checking it only with CPU-Z.

    With RealTemp (using settings) and CoreTemp (using F4), you can set the program to monitor several cpu parameters while they are running.
    Choose a short timing/reporting interval and you will have an accurate log of your cpu speeds

    Thanks again guys for your feedback! Your quite right of course I did have speedstep enabled as a safety feature! Didn't mean to imply that 100% test I was getting lowest value. My latest attempt has been a 12 hour stress test @ 4.6ghts using occt. I have got the attached results with core voltage offset of +0.005 and turbo boost voltage of +0.004 (lowest values) and vllc at lv3(50%). My target was to keep the core temp @ under 85C and voltage below +1.2v. I have a max core temp of 67C and max voltage of 1.14v. The snapshot is at the end of the test when speedstep has kicked in for last 5mins, prior to that as you can see it was running constantly at 4.6ghtz (I have also attached same test @9hrs 37sec). Is this a good result? How might I improve it? I would again very much invite any opinions :-)
