    Final day with OC tests is here. Finally. You finally see that. And of course, some power consumption of PC after OC.

    [​IMG]
    I like ROG many years. I switched to ROG boards since 2008 and after these years Im happy with quality, BIOS and features. So today:

    Maximus VII Hero
    i7-4790K
    Gelid Tranquillo+Delta fan 4000rpm
    Asus R9-270X DC II
    2x 4GB HyperX Fury 1866 MHz XMP (in OC tests are overclocked too)
    HyperX SSD
    Corsair AX1200 1200W Gold

    The motherboard is hungry for CPU:)
    [​IMG]

    And also for GPU :)
    [​IMG]

    I overclocked CPU up to 4732 MHz with Vcore voltage almost 1.4V. Its a lot? Is it enough? I think is it average OC for benchmarks for 4790K. This clocks are not full stable in OCCT or so, but its OK for all benchmarks test here. Concurrently is not possible cool it 24/7 with aircooling in stress loading. I think with very good AIR or allinone liquid cooler you can use around 1.35 V. This is around +0.1 V more than before with 4770K (thermal paste at chip). But changing the CPU from i7-4770K to 4790K is non sense. Only in this case - you are hard Intel enthusiast or you have very bad i7-4770K (4200 MHz max stable with good cooler). If I actually picked a new i7, take the new 4790K.
    And where is the hard stability? I had no time try it. Its very time consumed for me because I wanna every 0.1 MHz BCLK get to the final stability and back up to BIOS settings, change something and again the test etc...But I estimate frequency around 4600-4650 MHz


    And now finally the benchamrks at 4732MHz and 1.39V Vcore.

    Power consumption of PC (up described) without the monitor in Cinebench R15 is over 260 W. Thats not bad but at the same time not excelent. Its more than I measured at FX-8350 or i7-3930K, still lower 35 W than FX-9590.

    Nothing too practice, SuperPi today is just a good example of gross x87 performance without modern optimization.

    [​IMG]i7-4790K@4732MHz 4430cache superpi 32M=6m 52.090s

    Multicore Pi is better in effectivity

    Not much known test Processing power

    x264 FHD over 30 FPS! This is an excellent result, they themselves try it on yours home machine spreads and when you reach it around 20 FPS, generally have very good computer.
    [​IMG]i7-4790K@4732MHz 4430cache x264FHD = 30.07fps

    HWbot prime test
    [​IMG]i7-4790K@4732MHz 4430cache prime=6109b

    wprime is also very quick with this CPU and OC.
    [​IMG]i7-4790K@4732MHz 4430cache wprime1024M=156,344s

    In Wprime you cna try single thread performance, enough is 32M result

    Winrar with cache and OC RAM over 2400 MHz is over magical 10 000 Kb/s. Awesome.

    Sniper Elite is very demanding game on the highest settings, only 23 FPS, OC helped over one FPS :)
    [​IMG]i7-4790K@4732MHz 4430cache sniper elite=23FPS

    Far Cry II scales well with most of processors, help itself OC same type of processor? And I think so :)

    AVP benchmark

    Maximum OC for Superpi and memory
    After this category, each right Overclocker pushes CPU beyond limits, at least where it goes shorter SuperPi run and then validating. You can agree with it or you do not, for us, it's fun. Although the system can be in few seconds in BSOD is important to us see the numbers, the maximum clocks. Most mortals do not understand this, but this is my subjective opinion. They do not have the right experience and passion get the limits in competitions. Who to sniff once, hardly give up this hobby.
    Longer Superpi 32M with 5 GHz was impossible, I got later or sooner BSOD...4C/4T was OK, with 2C/2T was CPU more unstable :-/..Interesting. In 32M I got "only" 4913 MHz.
    [​IMG]i7-4790K@4913MHz 4412 superpi 32m=6m 35.382s

    Superpi 1M 4933 MHz with 1.45V
    [​IMG]i7-4790K@4933MHz 4430 superpi 1m=7.41s

    Superpi at 5027 MHz 1.55 V
    [​IMG]i7-4790K@5027MHz 4424 superpi 1m=7.160s

    5128 MHz OC
    [​IMG]i7-4790K@5128MHz idle

    I finally got the CPU for a few seconds to 5141 MHz with voltage 1.555V. For idle you cna be safe with 1.55 V, dont worry. Of course, you dont boot at 1.55V, example you are booting with 1.4 V and 47x and others settings doing in OS with software.
    [​IMG]i7-4790K@5141MHz idle air!
    [​IMG]i7-4790K@ 5141 MHZ 1.555V validace air

    Memory overclocking ? From basic 1866 MHz I got over 2666 MHz with 1.65 V! Excelent for cheap HyperX Fury.
    [​IMG]i7-4790K@4812MHz 4511cache RAM 2672 MHz

    Finally, a little humor here or there can be a beautiful bug. i7-4770K the last place from all processors. Atom is too strong :D
    [​IMG]i7-4790K@4732MHz 4430cache aida bug lol

    Hope, you like this minireview. Next time with LN2 and A10-7850K;)

    Good to see Haswell overclock like an average Ivy at the very least. Not bad for air cool.

    That's alot of work!! It's much appreciated, and I'm pleased at where it's at. I still don't feel it's enough to justify me moving up from 2600k....and I was hoping it would be.

    Its barely faster than my 3770k at same clocks. But atleast it reaches the same clocks so that is definitely an improvement from the 4770k.

    Unless you have 4770K like mine.

    4790K in my hands now too, you won't see me talking about it much. :p

    Thank you very much guys. Im happy you likes my work. So make it sense for me in future-more test with next CPUs again :)

    Very well test , I still wonder why intel don't use fluxless solder like sandy.

    FlanK3r, your wPrime seems slow by a big amount. I get 4.9xx and 153.xx @ 4700, 3900 cache, 2133 MHz ram (but with four sticks).

    Are your Fury sticks single-sided?

    Thanks for this very comprehensive "mini" review :)

    My 4770K already reaches the same ceiling at same or lower voltages, I see absolutely no reason to upgrade to Devil's canyon...

    So much for the Intel hype machine... Stable 5GHz on air... Give me a break. :ohwell:

    I want. My 4670k maxes at 4.4 and isn't even fully stable at 4.2. (1.3v) It all depends on the customer service rep I get. :p Full release is tomorrow (20th) right?

    yes, it seems single sided, what I see with my average eyes :D

    As impressed by the mini review you did. I'm almost equally impressed by the heatsink fan retention mechanism. :laugh:

    Nice work.

    I think 30 MHz, not 300 MHz :D....All depends at next factors as RAM, priority process etc. This was custom, no for highest score tweaking (I have much better scores with LN2, so non sense waste time with air tweaking OS and software/RAM at maximum)

    Well, like most off us have no time for LN2, we love tweaking on air, but most won't do OS tweaks, just system optimizations. I do nothing. :roll:

    That's why I asked if you had single-sided ram. I ran a bunch of benches myself yesterday.

    a pic of MY chip, and why I have no time for 4790K:

    Missing parts were in the bottom of CPU container. I'm not happy. :p

    More than you know, since 4.7 GHz works @ 1.25V, contrary to most ES samples. Stock voltages on this chip is 1.056V, load jumps to 1.2V.
