Did I overclock correctly?

[Akolyte]

Hello everyone, I'm brand new to this overclocking thing.  

 

And last week I overclocked my cpu to 4.2GHZ at 1.2voltz and I finally have the courage to tune my overclock.  I'm running an i5 4670k btw

 

So, at first I decided to go down like 1.2 > 1.09 > 1.095 > 1.08 etc.   Every single voltage down I have booted and passed a stress test successfully.  I managed to get down to 1.065v and I could have probably gone down more, but cpu-z still showed the voltage at 1.072 which I imagine was adaptive voltage trying to keep the chip stable, so I decided to turn it back to 1.075 just to be safe.  

 

After that I found my cache ratio was still on auto and was set to 38 which I wanted a little more for optimal performance, I decided to change the cache ratio to 40 to gain performance but also keep stability, as some people said changing it to a 1 to 1 ratio can cause instability,  

 

Now, I'm not sure how hot my cpu can get but I got to a max temp of 68c after the stress test and it rarely ever passed 65c on full load with my hyper 212 evo on silent mode in AIsuite 3.  

 

So, I've got a question, did I do this right?  What should I do next, and if I did it right.  Is my cpu at least half decent?  

 

@ProKoN I followed your guide, not exactly though as I wanted to start small.  Did I do it right? 

 

EDIT:  I forgot to add I've also got my XMP 1600 profile enabled.

For how long did you validate your overclock?

[SeanBond]

Sounds pretty fantastic, however you should keep uping the MHZ until it is no longer stable. It's nice to have low voltage but the chips are designed to run 15 years. So higher voltage won't mean it will die anytime soon. Get that extra performance! That cheap sounds pretty fantastic so go wild.

PS 2 hours of intel burn test and a day or two of intensive gaming should be enough for validation. 

[Akolyte]

I ran a stress test with Intel XTU for 2 hours, and I'm going to test out some games and run it in for the day, and then probably run a test for longer if I think it could be unstable.

10 pass on Maximum via Intel Burn Test should let you know if the clock is stable enough. Granted, it is completely possible to pass stress tests and BSOD on idle. In that case, you have some tinkering in the BIOS to do.

I'm a bit unsure right now, I'll see how this overclock is for the week or possibly month and go from there.  

 

If this chip is golden, I'm going to be super happy!  Although, before I go 4.4GHZ+ I wanna upgrade my cooler to something like a Siedon 240M so I can get some high overclocks.  

[AMICLG]

It seems like you got an amazing chip, run IntelBurnTest for 24+ hours.

I'm not gonna run intel burn test sorry, allot of people have said it causes the Haswell voltages to spike up, so I'm gonna use Intel XTU just to be sure.

really?!?!  Amazing?!!?  I thought 1.1v at 4.2GHZ was average? 

[Akolyte]

Okay guys, if I have a good chip. I'll save up for a water cooler and see how far I can go!

 

PS I wonder if I can boot at 1.105v?  

[AMICLG]

Haswell is pretty crap for overclocking and those are great temps/voltage for Haswell.

wow!  Thanks for the info!

Whatever you use, you should really stress longer than 2 hours. 2 hours won't validate a stable overclock.

okay, so how about 5 hours?

[MegaDave91]

I let mine run overnight and into the next day when I was at work.

I would be too afraid it would bsod.    I'll let it run 5 hours, and then play games all tomorrow?  

[Akolyte]

Alright everyone,  tried setting the voltage to 1.2 and seeing if I could get 4.4ghz on it, nope.  Was unstable, it booted up and ran a game just fine, just it crashed during stress test.  I've managed to get fairly stable at 4.3ghz at 1.175v with 4.2cache ratio. I've decided to ramp up the voltage slightly to 1.18 and see if its stable here, should be stable.  

 

When I get a new cooler I'll be willing to go above 1.2v.  I'm amazed at how I went from a complete overclocking noob to someone who actually knows what I'm doing!

uuhhhhhhhhhhhhhhhhhhhhhuhuhuh ha. Intel xtu test is intel burn test. It does not cause over volting. It's from the people who made your cpu

I bsod' like 6 times testing my overclock. It's not scary when you overclock. It just means it didn't work. Not that your pc died. Just don't pass 85C and 1.3V and there is practically no chance of frying your chip. Especially since it already looks great undervolting at an overclock.

yeah, I experienced a bsod on 4.4ghz at 1.2v during a stress test.  Even though I only get to about 70c at 1.2v I'm not willing to go above 1.2v without a water cooler.

 

But I'm currently at 4.3ghz at 1.185v max temp is 70c and cache ratio is at 4.2ghz and memory is on xmp.

I would try lowering cache back to 3.8 it adds instability without actually effecting performance. It's really not worth it on haswell. Didn't you say you hit 4.2Ghz at 1.075? How did you jump to 1.2 for 100MHZ? jeez

ikr.  4.4ghz needs a bit more voltage than expected I think.

If it makes you feel better my cpu is stable right now at 4.4Ghz 1.275V but isn't stable at 4.5 at 1.38V. Lol
