Flankers OC of Intel core i7-4790K Devils Canyon

[FlanK3r]

So, Devils Canyon finaly in my hands. I will tetsing now only AIR cooling OC and few benchmarks, so stay tunde. After weekend we will see.

With M7H, Gelid Tranquillo and 4000 rpm fan Delta at it.

Be sure to post some bios screenshots of settings for overclocking FlanK. What ram and video will you be using???

[FlanK3r]

video is my second R9 270x (first one I have in workstation) and I can try first HyperX Fure 1866 MHz and after HyperX Predator 2666 (at 4770K able run Superpi at 3150 MHz at air and voltage 1.72V)

[stasio]

No batch number..?

[xpower]

got no hope it will do any better then previous gen.

[darkage]

that's a great board isn't it ?
hope you have a nice air devil in your hands :-)
still ES ?

[dhenzjhen]

hey man goodluck! I think I found another low vcore chip, will post on Fugger's thread later

[FlanK3r]

still ES chip :-/

[chispy]

Keep us updated Michael , good luck on that ES

[stasio]

still ES chip :-/

ES..... special unrecognisable edition.

first stock (without multicore edhanced settings) settings and what the cooler at 4000 rpm

[FlanK3r]

i7-4790K@4732MHz 4430cache Cinebench R11.5=10.36b

wprime at 4732 MHz
i7-4790K@4732MHz 4430cache wprime1024M=156,344s

cooling air cooler Gelid Tranquillo+Delta 4000 rpm. I cant get more (maybe +0.1MHz BCLK) :-/. I hoped for 4800 MHz, but it crashed again and again. I tried steps from 1.35V-1.45V for Vcore and combination of vccin from 1.75 to 1.97V, tried PLX and still nothing. Seems average 4790K at air. Charles has better, I believe

PS: stil Im testing, so more results in next days.

[FlanK3r]

So, there is my BIOS settings, stable for benchmark, but not for OCCT/LINX...

antisurge
bios7

Extreme Tweaker settings (voltages, turbo, multipliers etc)
bios1
bios2
bios3
bios4

Tweakers paradise+digi power control settings
bios5
bios6

If someone have any tips, you are welcome :-)

Max validation 1.555V vcore, aircooling, normal ambients around + 24 C

Is that benchmarked & stable?

[Leeghoofd]

Boots perfectly fine into windows at 1.42 at 4900MHz... not stable though for CB15, not even at 1.5Vcore... too much heat

[darkage]

man the Z97 rog bios are nice, cant look to my rampage / chvf bios now ;-)
nice results as always flanker
and memory results ? is the same as Z87 ?

[FlanK3r]

coming soon, but I used 1866 XMP memory, so not superhigh result, but not bad after all...
Albrech: :-P, your is a bit better than my

Default clocks - stock Intel settings

Average seems i7-4790K better choice for daily users. There are better OC assumptions than retails i7-4770k. Why? If you have i7-4770K with long-term CPU and with very good cooler managed up to 1.255V, with 4770K could be in practice around 1.35V. Thats why with higher voltage (and lower temps) you can get +200 MHz extra. Of course delided 4770K will be the same or better than 4790K without it.
With LN2 is no difference between 4770K and 4790K overclocking. Depends it on luck of CPU piece.

In idle CPU working at 800 MHz
i7-4790k stock CPUZ idle

CPU with Intel turbo boost (not edhanced turbo by motherboards specification) will working always at frequency 4200 MHz. Interesting could be high cache clock, up to 4400 MHz at stock, so with next OC and higher clocks will be harder get stable....

AIDA was tested at XMP profile 1866 MHz. Haswell in memory work these syntetic test scaling very well (and continue effective in higher memory clocks too)

Fritzchess -all threads stressed

multithread Pi 80k size
i7-4790k stock multi80k

POV-RAY very stressed render benchmark in 151.26 seconds!

HWbot PRIME
i7-4790k stock prime

Cinebench R11.5 - very nice score for stock result
i7-4790k stock r11.5

The newest Cinebench R15 seems optimalized for Haswells, others good multithreads CPUs are worse here in higher difference (Ivy Bridge, FX) than in other multi tests
i7-4790k stock r15

wprime (1.55 vversion) - 174,592s
i7-4790k stock wprime

y-cruncher is very hard benchmark and stability test together, working example with AVX and its is the fastest PI number test, 500M in 110,5s :!:

3D Mark11, Performance test, my favourite new 3D Mark (result without OC GPU and without tweaks)...Grafika R9-270x DCII
i7-4790k stock 3D Mark11

Far Cry II test with R7-280x DC II, 156.43 FPS average
i7-4790k stock Far Cry 2

Unreal Tournament III benchmark, nice average 334,73 FPS
i7-4790k stock UT3=334.7fps

And what about OC tests result? Tomorow, finally

[csimon]

Awesome. Tomorrow should be good.

Why is 4770k(3.64gz) cinebench score higher than 4790k (4.00ghz)?

[poke349]

Nice!

Try the latest y-cruncher (v0.6.5). It will use AVX2 and FMA3.

[FlanK3r]

CSIMON: its bug in Cinebench, important is CPUZ, it must be higher clocks for it.
poke: ok, thanks
