Can't get a stable overclock on my Asus Sabertooth Z97 Mark S

Recommended Posts

Posted · Original PosterOP

First of all hello! 

Secondly, I've had this motherboard for quite some time now about 3-4 years now It's a really good motherboard and all but for some reason I just cant get it to overclock properly, I have to rely on the AI Tweaker to do the OC for me but If I do it? Nope! Infinite boot cycle or just plain old blue screen on. 

I'm trying to OC my CPU to atleast 4.7 Ghz ideally 4.8 as my cooler should be able to handle it just fine but it just wont do it. 

I've set my CoreVoltage to 1.250v as a basis but that just wont do it

my AI Tweaker manages to OC my CPU to 4.6 Ghz stable clock but when I do the same clock manually it just dies on me, What am I doing wrong? 

 

My PC Specs: 

CPU: Intel Core i7 4790K 

MB: Asus Sabertooth Z97 Mark S

RAM: 32 GB of HyperX DDR3 Memory

PSU: Corsair RM1000 PSU (Gold) 

GPU: 2x GTX 1070 in SLI

Cooler: Corsair H110i 280mm Radiator (AIO) (although this cooler is gonna be replaced in a couple of days with my new 360mm AIO from Coolermaster)

PC Case: PC Lian Li O11

I have lots and lots of fans inside the case so cooling would not be an issue here either.

 

Any good and reliable but understandstable info would be great!

Trying to push hardware past what it will do.

If it won't stay stable at that speed, then lower the OC. OCing is not a sure-fire guarantee on all hardware. Some parts won't put up with it.

And the next thing it's older hardware and degradation is a thing. I think you have to settle for a lower frequency.

My old 4790k was at 4,7GHz for two years, then it got unstable, next stable frquency was 4,5Ghz.

It should be well within' its ability to clock at that desired speed, If it can't handle it then I've been sold f false bill of goods.

If you dont want to raise voltage further there is not much more you can do.

 

If its unstable at that clock, youll have to lower it or increase voltage. Thats just the way CPUs work

I barely even OC'd this CPU I pretty much kept it at Standard Clock values since I've got it.

degradation also occurs when not overclocking. What you could do is to remove the heatspreader and change out the paste for liquid metal. and also lap your heatspreader and cooler (since warranty is long gone).

When you do that it would run at a lower temperature, and maybe you can squeeze out you desired performance. But most likely not.


>>But, you can kill your cpu doing that.<<

 

Also your CPU may not been able to OC to that frequency in the first place. That's the thing with silicon lottery and overclocking. The CPU of a friend of mine also clocked 100MHz higher, because he got a better sample.

And now for your inital question, the ai tweaker changes more than one voltage, for example uncore.

No you didn't. You got sold a CPU that will run at it's rated speeds and *can* be overclocked, but nowhere in the warranty or manufacturer specs does it say it *will* overclock.

 

Look at the specs right from Intel

https://ark.intel.com/content/www/us/en/ark/products/80807/intel-core-i7-4790k-processor-8m-cache-up-to-4-40-ghz.html

 

It says "up to" 4.4Ghz,

lol. 1.25v? That's enough for my poor overclocking 4770k to hit 4.3. My 4790k needed much more to do 4.8 but it did it for years with no issue but cooling it a huge factor for it.
