OC i7-4790K by FlanK3r

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


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:)



And also for GPU :)


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.
i7-4790K@4732MHz 4430cache superpi 1M=7.738s
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.
i7-4790K@4732MHz 4430cache x264FHD = 30.07fps

HWbot prime test

wprime is also very quick with this CPU and OC.
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.

Over 18k points in Fritzchess,simply wow for 8 threads

I like Cinebenchs benchmarks.

Memory nad cache subtest, Intel is excelent here!

Gaming tests at 4732 MHz (GPU stock)
UT3 benchmark, better +3 FPS :)

Sniper Elite is very demanding game on the highest settings, only 23 FPS, OC helped over one FPS :)
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.
i7-4790K@4913MHz 4412 superpi 32m=6m 35.382s

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

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

5128 MHz OC
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.
i7-4790K@5141MHz idle air!

Memory overclocking ? From basic 1866 MHz I got over 2666 MHz with 1.65 V! Excelent for cheap HyperX Fury.

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

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

 

[hardrock]

very good cpu and cooler
excellent test score

look forward to LN2 and A10-7850K

thank you man :)
