i5-4670K AT 5GHZ OC On a $30 Air Cooler, oooolala

Welcome back to Tech YES City this is video showing that my chip was able to overclock to 5ghz on normal conditions with a $30 air cooler (Enermax (aka Enerjizz) T40). The chip has been delidded and ambient temps were 17 degrees celcius. Also CLP was applied to the core and PK-3 was applied on the heatspreader (both with the spread method).

The motherboard used is a z87-g45 gaming, and is a great value for money board.

After playing around with settings on the bios, the core ratios did not work properly so this is a legitimate 5ghz on all cores on air. As a side note I do not recommend taking these things over 1.4v unless you have some spare change to buy another chip in case your current one bricks.

If you have any questions let me know and one good thing about this video was it opened my eyes a little bit as to why people might be getting bad overclocks on haswell, so I will make making a more in depth tutorial for you guys on how to get the most out of your Haswell chips.

Look forward to giving you guys another video soon also with a quick announce on when the live will be happening also.

Yeah I think that might be because of one sluggish core, hopefully I can get the guide out soon enough so you can get those other cores up to speed!

[techyescity]

Yeah the delid is neccessary for stability, you probably won't even get stable at 4.6 cause it will just get too hot before it can disperse the heat to the cooler properly (it was the problem I was having and it was the main reason I decided to delid).

[lldjslim]

That is just awesome. And especially using an air cooler and laughing at the $30.00 price.

And they say it can't be done. Nothing is impossible it's just imposable. Who out there is willing to do it.

Great job

De-lidded, That's the factor that makes it possible. I'm on a normal 3570k at the minute and I'm planning on upgrading to the 4770k in the very near future, I've been watching loads of delid vids but I don't know if I want to chance it myself as it's taking forever to save up for the upgrade and if I mess up replacing it would take ages, I may try delidding the 3570 first. That's probally the smart thing to do.

[techyescity]

Lol this was just for fun and games, my normal OC is @ 4.6ghz. I was told by someone who works at intel that up until 1.4v is fine for the most part, however past 1.45v is when that chip can face some serious damage.

[techyescity]

Yeah I will have to run some tests at 4.6ghz across various apps see what I can come up with.

[Consoul]

I'd love to see that advanced guide - my haswell runs at 4.4 24/7, had it to 4.5, but I feel as if there's more there to be had, as the temps and volts are within acceptable ranges . Thanks for the work!

[techyescity]

Yeah haswell's temps are mainly correlated to voltage I found.

[JackIT]

NICE! I tried to get 4, 7 @ 1.38 volts but temps go to high for me (>80°C) so my question is how much would it help to put the cooler directly on the die?
maybe i have to get some decent water cooling not sure?

[axle]

Thanks to your tips Bryan I got my 3570k ivy bridge to 4.6 at 1.19V maxing at 80C on Antec 920 cooler on silent mode.

[techyescity]

Might be better, but my temps are really good at the moment and I have cold air blowing down from the top, also I wouldn't want hot air blowing onto the back of my graphics card.

[techyescity]

Yeah see I think the ring ratio has its own sweet spot (I would have to test more, but I know having it at the same speed as your core is bad), try bumping the ring ratio up and giving it a bit more voltage, for me 4.1ghz on the ring at 1.1v is the sweet spot there, and higher and I got blue screened on my overclocks.

[giantesco]

I would like do delid my chip but I'm afraid to damage it. I did watch your how to delid video but could you show us how to apply the thermal paste? That's the part that I'm not too sure about.

[techyescity]

wow thats really good voltage for 4.4, when did you purchase the chip? I guess the new batch of chips are looking a lot better.

[HazewinDog]

oh my, what ancient version of the YES man did I just find!

[techyescity]

Was done in the morning at 17 degrees ambient (no aircon), dunno felt like saying oooolala since it was a pretty decent achievement to get 5ghz on a $30 air cooler :P.

[deadghostsclan]

i am getting less than 70 degree on 4.2ghz i have hyper 212 evo.should i go 4.4?

[chapinero]

awesome... now i m at 4.0ghz and my temps are 60 celsius tops, what should be my limit? like 65 celsius or less?

[ZeGermanBasterD]

So, can you run your Haswell with different clocked cores? And how much is the power consumption increase for a 1.4v overclock? Poor thing must be cooking, lol.

Since the benefit from overclocks is ingame maybe 5fps, I only recommend "Overclocking with brain". There's a sweet spot where you get a good OC with no insane voltage increase. Btw. Intel says the maximum save voltage for Haswell is 1.265v. ^^

[voyager]

i have mine at 4.3 using your 4.2 tut in prime 95 max was 86 degrees though in aida64 stress test it never went over 70? im using scythe ashura in push pull do you think i have a more headrom
