First time overclocking - i5 4670K ?

peter24345 · 11 May 2014 at 16:22

Hey
Im planning on overclcoking my i5 4670k and when i watched this video of linus tech tips he says that you should put your cpu multiplier to 46 on all cores ect. and see if the PC boots up ( Linus starts talking about it at the "Finishing" part ), is that a good thing to do because im really not sure whenever starting on a overclock that high is safe ?

Here is the video:

My system:
Asus Z87- A
i5 4670k
Noctua D14 CPU cooler (stock fans)
corsair vengeance LP 1600mhz
Asus DirectCUII 780 ( running at stock )
WD 1TB blue
Corsair 750RM PSU
Coolermaster 690 III ( Fans: Megaflow red LED fan 200mm, 120mm fan that came with the case at the back - dont know the name )

And could you guys give me any advice with what do do if I run into issues such as when the PC does not boot up, what would I have to do etc ?

I downloaded some testing software : Prime 95, Intel Burn test, AIDA64 Extreme, Cinebench, CPUID CPU-Z, CPUID HWMonitor and I also have 3DMark full version that I got on steam

As I said this is my first time overclocking and I want to make sure that everything goes well

Thank you

I had a Z87-A before the board i have now and it was a cracking board. The only reason i changed it was because i got the Hero for a really good price and changed my colour scheme. Anyway, i posted settings for 4.4Ghz in another thread and her is a link to my post. It may need a bit of tweaking as it can vary wildly from cpu to cpu.

Do not set the multiplier to 46x and hope for the best as there is probably little chance of it working. There have been some very poor clocking 4670k's about lately and you may even have to start from lower than my 44x above. Anyway, try that and see how you get on. Keep an eye on temps as Haswell gets very hot quickly.

Ohhh okay thank you that will help me a lot, why is should i not set the multiplier to 46, is that just too high for a start ? and if so why do you think linustechtips said to do that anyway ?

Like is said, it more than likely just won't work. That would give you 4.6Ghz and lately we have seen people struggling to get past 4.2ghz. I would suggest that you forget about hitting 4.6ghz as there are not many, even when there were good ones around, that will clock that far.

he was probably just testing if he had a good chip, if it boots stock volts at 4.6 you would have a good cpu for overclocking

... some motherboards would adjust the volts up automatically tho so watch this ...well did in my day overclocking

swampy · 11 May 2014 at 23:01

and heat is your enemy peter..search about for whats a good temp for the cpu you have ....when your pcs under load

pastymuncher · 12 May 2014 at 09:37

I can pretty much guarantee that no 4670k will boot at 4.6Ghz with stock volts. Haswell is pretty poor for overclocking.

From my recent experience (following various site guides), they all seem to have been created when the Haswell could boot into windows at x46 on stock settings.

My advice (and its not expertise, only experience of late), would be to start for a stable 4.2MHz-4.3MHz with default Ram settings (or lower, 1333)

If it helps any, my current settings:
Clock 43
Uncore 40
VID 1.3
Vring 1.2
VCCIN 1.8/9
Temps 80c Max AIDA64/XTU/LinX etc

Bam, i believe all of those testing programs you listed use AVX coding and so will raise the temps on Haswell. Try IBT which doesn't use AVX and it should be lower. Mine were around 15 degrees higher when using Linx but dropped when using IBT.

I tried LinX 0.6.5 after using 0.6.4(with no problems), my god, temps went through the roof, upper 90s within seconds. Not happy lol.

Not hijacking, and on the same lines as the OP, is the 4670k voltage or heat limited?
I've just seen the video of the intel rep saying "heat doesn't kill a CPU, voltage does". Sounded a bit back to front to me?

pastymuncher · 12 May 2014 at 19:11

Both can really, but voltage is the real enemy as it can degrade the cpu. Haswell has a major problem with heat though because of the crappy way Intel has done the IHS. This is why some people have been de-lidding the cpu's. Overall, Haswell is just a poor clocker. It will run out of steam before you run out of options in the motherboards bios even on a £80 board.

Yeah to everyone who replied etc. i did play about with overclocoking a little bit and i have to say that unfortunely the chip is pretty...as linus says below average as so far I managed to get my CPU stable at 4.2 Ghz at core voltage of 1.200 and multiplier 42 on all cores I haven't tried reducing the voltage for the stable 4.2 Ghz overclock yet as i wanted to see how far i could get with it and I dont think i can get past 4.2 Ghz which is quite annoying as i tried 4.3, 4.4 , 4.5 Ghz at various voltages and at 4.3 Ghz i managed to get through about 3 runs ( i cant exactly remember ) at high stess level until the pc would frezze so i migh be able to squeze into getting 4.3 stable with some or a lot of tweaking, my core voltage was at about 1.231 i think and later i just wanted to try 4.5 Ghz which i run at about 1.281 ish i managed to get into the proper desk top but as i tried running Intel burn test I would keep getting BSOD. So I think i will just stay with eigher the stock speed or 4.2 as there isnt much of a difference from the benchmarks ive done but im not 100% sure yet.

At 4.2 Ghz core voltage 1.200 i run intel burn test at maximum stress level and my max temperatures were 79C on the first 2 cores and on the last 2 they were 78C and 76C after 10 runs of running the intel burn test - my cpu was set at manual.

Well that really sucks. It seems that the latest batch are really poor and need a lot of tweaking to get anywhere with them. Did you try my settings that i linked to above?

peter24345 · 15 May 2014 at 19:40

Sorry for the late reply but I was busy for the past few days, yeah I did tried your setting and I wasnt able to get a stable overclock sadly I tried changing the setting but I didnt get successful ;( , ill try overclockong in a few days or somwthing as i have to revise for my exams at the moment. I have a few questions what should and how should you change the input voltage ? , when you're applying more core voltage could using to much cause instability or can that only happen when you use too little as I dont know if making really small increasements by like .01 help ? and last question I heard people chaning the ring voltage or something like that does the asus z87 A motherboard have that setting or not and what does it improve, change?

It would be really helpful if you answered those questions for me as they will help me a lot
