Is this Overclock Stable?

Setting Sun · Oct 10, 2013

I'm overclocking my I7 4770K. I currently have it at 4.5Ghz @ 1.24V manual. The auto thing in the Bios puts it to 1.248V and that's what it read under for CPU-Z during the Stress test.

I did 20 runs of Intel Burn Test at the "Very High" stress level. The highest temp I got using both RealTemp and CoreTemp was 85c. Idle is about 29-33c
I have my DRAM set to XMP profile 2400Mhz @ 1.65V

Additional info: Asus Maximus VI hero MoBo
Windows 7 operating system.

Is this overclock safe? 4.5Ghz @ 1.248V with custom water cooling loop on a 4770k. 20 runs of intel burn test on very high.

Hi,

Your load temps are pretty high, have you tried using abit less Vcore?

Also I would stress test the overclock for atleast 8 hours (preferably longer) with prime95, OCCT or similar.

personally thats too hot, drop to 4.4 and drop the voltage a little. for benchmarking you are ok, for day to day usage i'd say not.

Well I have the vcore set to adaptive in the Bios so when the PC is idling it lowers. I figured there's nothing I can do in a realistic scenario that would ever get my temps as high as intel burn test?

So you still think I should drop it a bit?

for long term use, yes

Neither IBT nor P95, tests the full system load with the audio and video in use!

Once IBT says you're supposedly stable, then use some benchmarking programs on extreme setting to stress the graphics added load, looping the testing on extreme is even better, a crash indicates the vcore is not high enough and needs a bump up.

Then do some PC gaming to stress with the audio added to the mix, a crash gaming indicates the vcore is not high enough and needs a bump up.

Now you as the user are responsible to determine if the overclock you're running is within safe load temperatures, that is always determined by how you overclocked in the first place and the cooling solution you are running.

Many running auto overclocking are actually running higher spiking voltages out in the operating system than they really need, and they run the auto overclocking because usually they're just too lazy to learn how to manually overclock, they want the easy way out.

Keep in mind that stress testing programs run higher load temperatures than regular applications do, so a too high stress testing load temperature does not indicate a benchmark application or gaming temperature.

Temperature wise you're adding extra heat to the CPU running your memory at 2400mhz, which means you are overclocking your 4770Ks CPUs memory controller and adding extra heat in the process.

You're also running the memory at 1.65v adding additional stress to the CPU,

I played some planetside 2 on all ultra setting for about an hour and my temp was 44-45c. I decided to take the advice from above and lowered multiplier to 44 and vcore to 1.200V.

Now screen artifacting with white lines so bad pc won't even boot into windows. What happened? 4.5gjz stable, now I lowered it and PC won't boot.

You have just ventured into overclocking, I suggest you learn what you're doing first by studying overclock guides relevant to your hardware, before you damage your system permanently.

You can always overclock later after you learn how, I suggest you return your settings to default, learn all the aspects to overclocking and how to do it.

If you had that knowledge this thread would have never been necessary.

If you could care lees whether your hardware is still operational in the future, then by all means don't listen to me, do what you want.

because you lowered voltage arbitrarily, as 4ryan6 said, learn then do.

Yeah my gtx 780 is toast for some reason

Seriously?

The very reason I tried to warn you about overclocking without fully understanding what you are doing was to keep you from damaging your hardware.

Well at this point have you learned anything?

Setting Sun · Oct 11, 2013

4Ryan6 :

Of course, but you must understand I am a first time builder and even with proper research mistakes are inevitable. However the overclocking of the CPU most likely pushed the GPU over the edge, but isn't likely the root of the cause.

I probably didn't install the aftermarket GPU Waterblock correctly and damaged the card, or it was just a faulty card. I'm not blaming any hardware damage on my overclocking

4Ryan6 · Oct 12, 2013

Setting Sun :

You're a first time builder and overclocker as well, according to your other threads, I'm not trying to rub salt in the wound just trying to get you to understand you are not alone many have destroyed their hardware overclocking!

Usually when they do and realize it, they disappear from this overclocking section not to be seen here again, I'm trying to get you to realize how important learning what you are doing first, before you actually do it, is.

Once you learn what you are doing you would never ever need to post a thread titled as this one, because you would know the answer!

I wish the best for you, and I hope you have not permanently damaged your 780!
