Amazing, super straight forward and easy to follow, got my i7 4790k to a stable 4.6 ghz. Thanks a lot :)
Can you share the settings configuración?
From much reading and testing and watching videos like this it even says this in some BIOS "the uncore frequency NB should be equal or at most be 100mhz less", otheriwse you will get juttering lag spikes in games like Fortnite, many of the overclocks you see are 4.5ghz with a uncore probably not set correctly so temps are lower, IMO the 4th gen I5 max out around 3.9 - 4.3 for daily use with with both clocks set equal and good air cooling but maybe you could get more with water. The max safe temp 72c on intel site, so say 73C anything over 75c is some risk, i've got my 4670k to 4.0ghz i delidded cpu at 100% use on a cool/warm day i'm getting 68-69c max temp, so still to hot for summer when the room temp goes up. so max 3.8 or maybe 3.9 after fine tuning in volts. in winter maybe better but i'd rather have it max safe speed all year. this is still a £60 cpu in 2020 so not the end of the world if you brick it but annoying.
you can overset them nb and link freq, someone said it gives more stability
It works vut later I have problems booting up from the sleep mode.
Hey man great video. Thanks. Clean and simple. Working well for me right now. Got a noctua nh-d15 on this bad boy.
hey my friend i did everything exacly how you show
i have the same bios like u and same cpu and when im in advanced frequency setting wont let me change cpu base clock to manual how come ?
Press F2 when in BIOS, then it should change to "SMART TWEAK MODE". When in there you should be able to change the base clock to manual. :)
You can press space to change to manual
I have same cpu and same BIOS but your advence freq setting is different because i got only proc.
Graphics clock
Cpu clock ratio
Cpu freq.
Advenced cpu core
System memory
Memory freq.
Thats all what i got.. do you know why?
Ich denke das Bios von meinem Gigabyte Z97X SOC Force Mainboard ist identisch?
King..
i follow all steps, but my performance go down (5-10% benchmark test) , i have a i7 4790k and i put it to 4,3gh like u (4,0ghz stock)
my ram in running 1866mhz and 1,5v, my gpu is 970 g1 :S
+WalkandPeace i didn´t see the temp. i will check. Ty man
+kttiger666 which benchmark exactly?
+der8auer ungine valley, i get 132 fps with stock value, and 126 fps with 4,3ghz oc
+kttiger666 Try 4.4 GHz OC please. 4790K can go up to 4.4 GHz with Turbo multi. So depending on the current TDP it could be that your CPU was running 4.4 in unigine. Maybe try to compare with Cinebench (Multithreaded performance)
My CPU temp is stable at 75°C is that a safe temp to be at? Thanks for this btw.
In general, for most PC parts, try not to go over 84-90 C.
yeah i would keep things under 80c to make sure cores run optimally wo throttles, but not sure every board are different
Why cant i change the cpu clock ratio? Im pressing + or - .. i5-4690K 3,50GHz
Press them in num pad
Four years later I’m playing with a Core i7-4770K on an Asus Z97 motherboard. This came in super handy!!!! Oh my gosh thank you!!!
I am still using my i7 4790k @4.7GHz, it is still very powerful and fine for a few more years :) I love this processor, totally worth it and it is still fine and powerful enough.
What was you Configuration?

THANX ALOT
This Video very helpful to me.
Can you upload RAM overclock?
you can try but its sort of harder than cpu gpu, or more headaches
This was really helpful and it was recommended to me on how to overclock for a noob like me
Mine gets stuck at exactly 3.67 ghz. What could be the problem?
Everything was working fine. Today I turn on PC and I get a bootloop with no access to BIOS....
LOOOL all these dumbass people who have 0 clue what they're doing hopefully they sell there pc if they dont know what a cmos reset batter jumper or maybe button is
soupbruh geng. I can't understand your grammer.
i followed your video and find it very helpful... i have a i7 4790k @ 4.6ghz with Vcore 1.254 the temp im getting is 86 degrees after 8 hours of aida64... is this fine or should i increase my Vcore or lower my multiplier?? Please help...
+KOGSKI BUGARTSKI Temperature is fine :) 8 hours of aida also means it's pretty stable so no need to increase the voltage. You can still increase it incase you experience any instabilities
Thank you! This video helped me out SOOOOOO much!!! I've been getting confused on how to OC with this mobo. Just tried my first OC now, years after your upload.
lol i did it just now
thanks man, running world of tanks patch 9.13 @ 112fps 1920x1200 maxed out
Hiya! Thank you very much for posting this guide, have got that board & chip (an a aftermarket cooler), so i will give it a go tomorrow evening :)
I have the same CPU as u and did EXACTLY what you did but CPUz says my CPU is clocked at 799 MHz why?
Intel Speedstep will clock down the CPU in idle. Change the power saving option to maximum performance and it will always be at the max clock
thanks it worked, how high should i overclock my cpu, i have an aircooled cpu, im new to overclocking
I am in a situation where I have no display during the bios setup. Just to be sure, how exactly do you navigate between menus and set things correctly?
Ich habe das selbe Board und einen i7 4790k und wollte diesen nun ein wenig übertakten. ICh gebe die Werte im Bios ein wie im Video beschrieben, doch nix tut sich, jedesmal wenn ich ins Bios gehe sind die Werte noch da aber sie werden nicht gesetzt, die CPU bleibt bei 4,4GHz (es ging aber mal nach dem Kauf). Bios VErsion ist im Unterschied zum Video F8.
Habe ich da irgendwas übersehen? Kann ein Defekt vor liegen? Montiert ist eine Kompakt - Wakü und somit kein Lüfter am CPU Fan Header
Habe exakt dasselbe Problem beim gleichen Setup. Hast du eine Lösung gefunden?
Best video yet for OCing a Z97 Gigabyte board.
Can one help me please, I followed this guide and managed to get a stable overclock of 4.5ghz with 1.21v is there a way now to bring voltage down when PC is in idle mode
Not sure if you figured it out, but one of those c-stats probably relates to this.
thank u 4 this video ...... and i need ur help ... i got 2x8 gb ram and thy run at 2400mhz .... but 2day i bought a new kit as the same old 1 ..... so i have 32 gb of ram and the same MHZ ....but they all runs at 1333mhz .... so my question is ( how to make all RAM run at 2400mhz ? ) .... FUI my reg is : MB ( GIGABYTE G1.Sniper Z97 LGA 1150 ) .....CPU ( i7-4770K, 3.5 GHZ, 8MB Cache ) ... RAM memory ( 2 kit Kingston Hyper X 16GB DDR3-2400 mhz ) ..... cpu cooler ( corsair H100i GTX ) .... VC ( gtx 980ti ) .... and my OS is windows 10 64bit
Hello, I really like your tutorial, I only have one question about it. Is it possible to overclock the processor (I have the same motherboard and i7 4790k processor) so that the idle processor has a reduced clock speed, and only in games, or during rendering, to what processor was it overclocked (in my case 4.7 GHz)? best regards
Great guide. I overclocked my i5-4790K to 4,4 GHz @ 1,21 V. Maybe later I will try to reach 4.8 GHz.
Have the exact same motherboard and CPU, but when i save and exit, i cant even turn on my pc?
you need a cooler heatsink and fan. prob using stock fans.
Just tried this on my 4770k and temps were okay but about 10 or so minutes into prime95 stress test I got a BSOD. Going to try voltage at 1.27 now
so the time has passed and i rly whant to oc my cpu hight.... need tips from an expert
cpu: 4690k
cpu cooler: coolermaster neptop 240
mobo: gigabyte z97x gaming 7 (bios f8)
ram: g.skill tridentx 2400 cl10
psu: evga 750watt gold 2
storage: ssd samsung 256pro
im about to change my sapphire r9 390x try-x to buy some 1070 or 1080 if not bottlneck or save it somehow with some good oc...
thnx for your time
i only got 4625mhz from my cpu... and aat rly bad voltages... dont know why :/
Hey I still see your still posting videos on YT. I hope you see this and can help me out. I tried this method but I'm getting Boot Failure Detected after trying this. Why's that?
I have an i7 4790 non K 3.6ghz stock , i have set to 4ghz and 39 cache, it is running prime95 at 3800 ghz can see with core temp and temps are stable 52-55.. Can i push it any further? what should i do my first time overclocking with ur guide
Hello der8auer,
Can I use your Haswell OC-Frame with a delidded 4770K and is it compatible with AIO cooling like Corsair H115i?
And most importantly, is it worth it when using AIO cooling or is this for LN sessions only?
Thanks.
any recommended setting for g1 sniper 5 , 4790k 5ghz. currently 4.8ghz , 1.7 vrin , 1.35 core.
I don't have base clock option. So I can't set to manual. My i7 4770k cores stay at 3790.95mhz no matter what I do
I have a i5 4770k on 4.3Ghz works well with this guide i have a z87-d3hp-cf motherboard and 16 gb of ram.
i have a gigabyte z97p-d3 i5 4690k 8 gb 1866mhz any tips on how to get 4.00ghz
i follow all the step but didnot work for me i have a i7 4770k gigabyte z87 motherboard
Nice one my PC start to be a little bit old
Hallo der8auer,
ich habe ein Gigabyte Z97X Gaming GT Mainboard. Das BIOS sieht dort ganz ähnlich aus wie in dem Video. Darauf betreibe ich einen i7 5775C. Es lässt sich soweit auch alles gut übertakten, jedoch hält die CPU in Prime95 nicht den Takt, sondern kommt nur auf ~3GHz, wo dann das 65W TDP Limit erreicht ist. In Games taktet die CPU ganz normal auf 4GHz. Nun ist die Frage, wie ich das TDP Limit umgehen kann?
Eine Antwort wäre cool.
Gruß,
JBO
Hallo danke für die Anleitung auch wenn ich meinen 4690K
schon eine ganze Weile mit 4,4 GHZ am laufen habe.
Bin aber noch nicht so ganz zufrieden da ich mein wunsch Takt von 4,5 oder 4,6
Ghz nicht so wirklich erreiche.
Wie gesagt im Moment läuft die CPU Rockstable mit 4,4 Ghz und 1,245 Volt. Temp
gehen nicht höher als 65 Grad und das trotz Luftkühlung.
Bekomme auch 4,5 Ghz so eigentlich am Laufen und auch unter Prime einige
Stunden und das ohne weiter die Spannung anzuheben und Temps sind dann noch
immer max auf 74 Grad. Irgendwann ist aber schluss (beim zocken oder was
anderem), bekomme einen Bluescreen und werde beim Neustart dazu aufgefordert
wieder ins UEFI zu gehen L
Hab das Gefühl das
auch die 4,6 Ghz kein Thema sind aber da das meine erste CPU ist wo ich mich
endlich mal ans OCen ran gebe, bin ich mir ziemlich sicher dass es bei mir nur
an den UEFI Settings liegt und da irgend eine Kleinigkeit nicht optimal
eingestellt ist.
Wäre echt super wenn du da noch den ein oder anderen Rat hast und mir da weiter
helfen kannst, wäre dir echt dankbar dafür ;)
Ach ja, mein System:
Gigabyte GA-Z97X-UD5H-BK Black Edition und kühle die CPU mit dem BeQuiet! Dark Rock Pro 3
Hab dir mal ein paar Screenshots von meinen UEFI Settings hoch geladen. Bin mir
fast sicher das du sofort da den Fehler findest warum es bei mir scheitert :D:drive.google.com/open?id=0B52usPTk2gR3UV9LaGJWSVl5Rnc
Vielen Dank nochmal ;)
is there ways to get a nice OC but also have it clock down in idle so its not running so high for no reason?
can guide me to oc my g3258 with my gigabyte z97 gaming 5 .. thanks in advance
Hab einfach das Video angeklickt ohne zu schauen von wem das ist ... und dich dann an der Stimme erkannt :D Immer top der Roman!
thank you sir, for you time
Thanks !
Please I knows its old but how u disable secure boot
well disable it
I got stable 4.4 and temperature i get on 4 cores is like 64-67 max when i testing can i go more then/ how more this i5 4690k can handle max ?
Unclle Crappy4K What's the voltage?
Thank you so much. Just did this to my 4670k and its so much smoother now lol less gpu bottleneck
Do you mind sharing your bios settings to me by any chance i have the same cpu and needed some help
Hello, it doesn’t let me to change some settings like cpu base clock, it’s on auto and can’t change it... any idea ?
Please make sure your motherboard supports overclocking, it requires a Z chipset and K cpu.
i got my i5-4690K to 4.8GHz on Z97X- gaming 3 MOBO 1.325v
Great, my I7 4790k can't do more than 4.7GHz but I am also really happy about it because it needs just 1.264v and stays cool :)
still working?
Followed everything, however when I key in a certain multiplier it doesn't follow the Core Voltage that I want to use.
In example, I want to run 4.3gHz at 1.000 Volts and I set it up that way when I load up Windows it goes to 1.112V or something higher.
The issue is I want it to follow my Voltage so my cooler can handle it. Just a Hyper 212.
It wont be stable at 1v, at least 1.115v. Tried the other bios and take out the auto option from cpu voltage
I think what's holding me back is the poor TIM used on this generation, also I think I'm lucky with the Silicon Lottery. I don't need high voltages.
BTW I prefer the older/classic bios vs the new UEFI.
Got my hands on a review sample for a Noctua NH - D15S
Here's what I got.
4.2gHz 1.020Vcore
Average Idle: 37 °C | Average Load: 68 °C
4.5gHz 1.120Vcore
Average Idle: 38 °C | Average Load: 75 °C
Due note that the results are done in a tropical climate with no Air Conditioning so results are really warm.
Average Room Temperature is around 35 °C, test was done during the hottest time of the day.
Thank you so much. Finally got my chip where I want it :)
Hi, warum kann ich bei den core voltage nichts ändern?
going give this a go on my sons christmas pc...gigabyte gaming 3 with an artic freezer 130 on a i5 4690k
any more tips you have before i start would be great..wish me luck
+Thomas Kerwin Just start with the tutorial :) Should be good in general. If you have issues - just post and I will try my best to help you :)
+der8auer got it running at 4.4ghz stable on 1.250 volts .iam happy with that so iam going to leave it for now.ha.thanx for the help mate
hi @der8auer
This video of yours is great. I tried it on my setup i5 4690k with GIGABYTE z97x GAMING 5 and 8gb(4gbx2) KINGSTON DDR3 1333MHZ using AIO liquid cooling I set my multiplier to 41 x 100 = 4.1GHZ with manual VCORE 1.120v. My MAX temp went to 85 during 10 minutes prime 95 test with no error. I stopped it because I worried of the temp is too high. I just stop at this setup but want to go up until 4.3GHZ, and wanted to reduce the temp not reaching 80. Can you give me tip on how to attain 4.3GHZ with below 80 temp. Also, How can I OC my KINGSTON 1333 MHZ, I dont see any xmp profile in my mobo BIOS. Thanks in advance
+christian D Hey! Your memory modules don't have XMP. You can try to increase the DRAM Voltage to 1,65 Volt and set the memory clock to 1600 MHz and see if it works. Maybe even 1866 MHz.
Temperatures seem very high for AIO. What thermal paste do you use? Maybe adjust fan speed to run higher?
+der8auer thanks for the reply. you mean to say, i can still adjust the MHZ of my RAM from STOCK1333 to 1600MHZ? but just add the voltage of RAM from 1.5 to 1.65? In regards with my temp using AIO, i used the paste inclusive in the AIO it self. How can I adjust my FAN speed? Thanks in advance
+der8auer hello sir, I tried to lower my VCORE from 1.25 which you shown in video to 1.100 and up the MULTIPLIER to 42 making it 4.2ghz. I am a bit worried with the temp which hits 85. Is it still ok?
If it went to 91 in an hour should I scale back down the over clock or increase core voltage?
Or decrease it?
how do you set your memory on this Motherboard.
Hi. Is 2600k possible?
yes
i have i7 4770k
m1 sniper m5
and on bootup my pc crashed
+Osher Kalifa Try a lower CPU multiplier first and see if it works. Set CPU Clock Ratio to 41 or 42
Hallo eine Frage! Wenn ich die Vcore auf Manuel stell und einen Wert eingebe taktet die Vcore dann im Isle Modus mit? Oder bleibt sie immer gleich?
Das kommt auf den Modus an ("voltage apply mode") dort gibt es Optionen wie "fixed", dann liegt die Spannung immer an, oder adaptive, override, offset usw. Bei diesen Modi liegt die eingestellte Spannung nur unter Last an, wobei diese durch den vdrop und lcc leicht abweichen kann. Ich würde den adaptive mode nutzen. Das ganze ist im Haswell OC guide von PCGH nochmal näher beschrieben. :)
I overclock my i5 to 4ghz. 1.200v. Is it good?
Wich one are u using? U can set to 1v to run at 4ghz. if doesnt go well increase 0.05v untill work
Great video thanks boss
Mine crash with those settings
Thanks very much!!!
I have the same mobo and cpu ,but it wont let me change CPU Base Clock to manual.
Did you figure it out?
@@Pr3mierez Hi yes to change values you use the + and minus keys on keyboard.
I got my i7 4790k on 4,4Ghz using Noctua tower cooler.
I use 1.300V core voltage.
temp is 80-85°C
so thanks for this Guide.
thanks for the feedback :)
+der8auer i test a little bit.
my cpu runs fine at Vcore 1,200V.
it doesnt increase 60° now.
I am surprised what 0,1 volts can do.
I've an i7 4790k too but idk why it got undercloked to 3.8ghz?
Vaibhav Negi make sure you disable turbo boost....it's under the frequency settings then scroll down to advanced, open that and you'll see the turbo boost, it should be on auto just disable it
When I go to change the xmp the option to do it is not even there..
Theres only system memory multiplier and memory frequency. Help please
Is it possible to put in the multiplier manually, and what should I put it on in that case?
+Klump Bauer some memory modules don't have XMP :) In that case just skip this step and move on.
der8auer ok, thanks!
Did not work for me with my i5 4670K @G1.Sniper Z97 cooled by Prolimatech Megahalems rev. B.
Also: in this video and your linked guides you totally run contra to what you say in your guide posted on PC Games Hardware forum - that one could keep the power saving options [Enabled] - why?
I'm not mocking this video, i just think that 7 minutes are not enough to skip the 'trial and error' part and maybe get a 1 hour prime stable setup - i just started overclocking my cpu again after i sent my air cooled Q9400@4GHz into retirement.
Maybe you should consider showing all the important bios settings instead of only the main settings?
Consider this constructive critics, i love good video tutorials if i can avoid reading tons of text and pdf documents ;)
+novocainDaimon These videos are for those who don't want to read text and don't want to do trial and error :)
well, thats why i watched it - currently trying to fix the mess that tutorial left for me (cant boot my windows even at stock settings)... X_x
+novocainDaimon Just load optimized defaults :) Also make sure the AHCI settings are correct
+der8auer I already did that - optimized default settings loaded, SATA is set to AHCI, boot loading order is set up and i keep getting INACCESSIBLE_BOOT_DEVICE BSOD...
😂
Thank you so much! Good video!
Dude thank you for this video.
How do you change from auto to manual
+Dr.Epiforce Games use + and - on your keyboard :)
Hi i have problem bcs dont have xmp
Should i set memory multiplaier to 16 ? Bcs my ram frequency is 1600hz
I7-4790k at 4.5ghz and max temp was 89degrees, is that ok?
+Low Top sounds good :)
+der8auer if we want to put our i7 4790k at 4,5ghz, we have to use the same voltage and parameters that we can see in that video?
no its not, i did play at 84-86c with lga775 but i think cpus with boosts should run under 80c for optimal perf
im not sure since ive never had k series intel, so check yourself
would my cooler master hyper 212 evo be enough to stay under 90???
+Ray-Tube i also have a i5 4690k
+Ray-Tube Should be fine for 4.3 GHz yes :)
+der8auer I just had the time to overclock, running prime95 right now. temps are around 65 c° with the settings you used :)
+der8auer same cooler to, but i'm using another mobo: gigabyte gaming 3
+twan duvigneau You can probably increase a lot of your CPU is running at those temps and stable. The reason people get water cooling is so they can clock their CPU's much higher than the air cooled method. I personally started with the 212 evo, it's an amazing beginners CPU cooler and for a mild clock it works very well. Just be careful when over clocking because you can lower the life span of your processor if you clock it too high and even damage it. He should have warned people in the beginning of the video that his viewers should be aware of what can happen if they mess around too much with the voltages and speeds. I did enjoy the video, though.
I7 4690k? LoL?
You mean I5?
+tom hill Btw, Not bashing video. Good Vid, simple mistake, and might wanna fix, can mislead some people hehe.
When Asrock Skylake guide? :(
+Domino0441 working on it :) Hopefully tomorrow. Well at least a Skylake tutorial. Only have ASUS Boards here so far. Still waiting for the others.
+der8auer Ok, thanks! Your guides are veeery useful!
Can't thank you enough for this, got a nice stable overclock to 4.3, I backed the voltage off from 1.25 to 1.2 as it was a touch hot on my system but running very stable now! Thankyou!!!
I have the exact same setup you just displayed and the oc is fantastic.. Your a boss man!!
Just a tip, i5 4690k at 4.3ghz runs really good at 1.125v, dont need to increase above 1.130v
Why do you put Memory Clock to 2400 MHz if you're stock is 1600 MHz?
At the end you say "Check if it is stable, if not increase the voltage". What do you mean with "it" ? Do you mean stable temperatures?
(Thank you! I'm new(b) to OC'ing :p)
+Matthijs vd Poel 1600 MHz is the stock without loading XMP :) If you have XMP memory (my kit was 2400 MHz) and don't activate it, it will run at 1600. With "it" I meant the CPU. If you overclock too high, the system will become unstable. So you have to test for stability/instability :)
i dont have XMP setting in the bios, can i still OC? my ram is running at 1600
Thank you men, what kind of cooling did you use? Did you try at 4.7? Thanks in advance and greetings from Bulgaria.
Yep works ok, but my PC didn't change. It's still slow!
Hi, for some reason i cant change the voltages you know why?
Is 40 cpu temperature (in bios) safe enough to overlock it from 3.5 to 3.8 or 4ghz ? And what voltage would you set for 4ghz, like 1.2v ? Thanks.
thats idle temp, highend haswells are 4 or near 4 by default, you should aim at least 4.5 imo
i personally think haswells are best like very polished and efficient, so oc it to the max
This was a great guide! Thanks so much, it was very detailed and you saved me a lot of time reading about over clocking with this. I pretty much get what you have to do and I would like a much more advanced video and more detailed explanation of over clocking and if you could do that, hell, that would be amazing! I liked and subscribed.
+Bryan B You should also put some warnings in your video about what can happen if someone tries to get crazy with the voltages and speeds on their CPU's and RAM. Mainly because a lot of people just don't know and maybe they want to get into OC'ing.
Hello, your guide helped me alot but i have few problems.
I have i5 4690k with gigabyte z97x-SLI with Cooler Master Seidon 120V water cooling and my temperatures always hit above 90*C. I set my OC on 4.1 GHz with 1.116V, any thoughts on this ?
+iress22 sounds pretty high indeed. Did you check the cooler-mounting and thermal paste? Maybe you have to consider to delid the CPU and swap the thermal paste.
+iress22 Try Prime 95 v26.6 it is the best Prime95 for Devil's Canyon CPU's (4690K and 4790K). Makes the CPU run cooler but does the job for proper stability test. You may want to re-mount the water block to the CPU, that seems a bit high for only 1.16v.
