P95 running(at least for some time, IBT completed. :)
IBT is short enough.

Thanks. Will add you as soon as you post! Sorry!

"Just to add: Other BIOS settings can affect that as well as offset voltage.

Many that shoot for the high multipliers approaching 5ghz use manual voltage settings,
taking full control over the voltage and not allowing the motherboard to vary it much out in the operating system.

You're showing a typical ASUS base clock reading of 99.98mhz, if you'll set your base clock to 100.1 in the BIOS it will read out at a solid 100.

Also you can run Intel Burn Test to shorten the time you spend seeking stability, IBT will expose instability in minutes vs P95s hours.

Personally I just don't have the time to invest 12hrs running a stress test, when in actuality no stress test completion is reaching a 100% stable overclock.
Further benchmarking and gaming adding the GPU and Audio load are the final tests to reaching 100% stability.

But further testing to reach a solid 100% stability is not required to be a stable member of this overclock club.

But 100% solid stability should be important to the individual, if he or she plans to run their overclock for 24/7 use, error and blue screen free."

Hopefully not too non sequitur- but any of you XTU experts know how my OC'd i7 4940mx can read processor frequency of 0.00GHz during a stress test? I'm a rookie. Thanks. Photo: www.flickr.com/photos/125791570@N08/14584015848

Sorry if this has been asked already but is an overclock considered unstable if it's throttling in Intel Burn Test? I'm able to stress test with aida64 with no heat problems but when I use IBT, it overheats and throttles down to 80%. The test completes normally and claims the system is stable.

What are the temps you getting with itb then???

I'm hitting the upper 90s in Intel Burn whereas aida64 has them averaging in the mid 70s with the occasional spike to the mid 80s. Regardless, I got it to pass Intel Burn Test without throttling (it's amazing what happens when it drops 10 degrees overnight and you leave your windows open). I'll post my results in a new reply so I can join the club.

Throttling is not instability, throttling is your CPU protecting itself to keep it performing error free, until it gets too hot and shuts down.

Some overclockers are perfectly fine with throttling taking place, and others do not want to see it happening, as it will affect benchmark score results, the greater the CPU is throttling, the worse the end benchmark score results are.

There are also various BIOS settings that affect CPU throttling, especially when power saving features are active, but that does not mean your overclock is unstable.

Now if you get a Blue Screen while gaming followed by your computer restarting, you're unstable, guaranteed.

I still wanted to pass the Intel Burn Test without throttling just to be on the safe side. While I was experimenting with lowering my vcore, was having stability issues despite it passing ITB. For instance, I was running it at around 1.2v and it was passing ITB but throttling as well but when I stress-tested that overclock in aida64, I was getting a BSOD after a few minutes.

I can't help but feel that since my CPU is being throttled, it's not being tested at the performance I actually want to test it at for stability. While it may be stable when it's throttling down to 3.9ghz, it might still be unstable at 4.6 but I would never know due to it not actually being tested under those conditions.


 


No stress test is the end of your quest for stability as they do not test GPU or Audio load, you continue to seek stability after successfully completing the stress testing, you then graduate to testing using various benchmarking like Futuremark etc. usually requiring more CPU voltage to stabilize past the stress testing stability, then on to gaming to see if GPU and Audio is stable and if not even more voltage is required to reach 100% stability.

I downloaded a intel program for OCing and gave it a try:

I did not know about the intel burn test and just downloaded and tried it out.
it passed at standard, but did not know if I should go to a higher level ????

Thank You, I will try it out on High instead of standard.

 


You can run any stress test as maxed as you want or as long as you want, but that is not going to mean you are 100% system stable!

No stress test is an all in one tester, it is only the first step in reaching 100% stability as it does not test Video and Audio load.

Further testing with benchmarking will add the GPU load and some benchmarks even some Audio load, but gaming is the end test adding GPU and Audio load, which always requires a bump or two higher CPU voltage to stabilize the overclock for 24/7 use.

If you're running a partially stable machine that's only managed to complete IBT, OCCT, or P95, then you are not 100% stable, and running that machine with a false sense of stability will result in file corruption from the crashes you will encounter, from blue screens to complete sudden machine shut down and restarts when you fully load up the system with your favorite game or application.

File corruption can in some cases lead to completely having to reinstall your operating system from scratch.

There is a big difference from the stability required to post an overclock in this thread than a 100% rock solid stable machine!

I have been upping voltages and having the system restart....but I had no idea that it could mess up my OS at all !

I had recently had to completely reinstall windows as I had a malware problem that wasn't allowing me to
use my pc in a correct manner. It lowered all of my security and pc was not working right. Now that I have
everything back, this disturbs me that I could be messing up my OS again. Should I do a system repair
or is there some check I can do to make sure I am at 100% ???

thanks so much for telling me this, I really appreciate it very much !!!!!!!!

 


It is a normal process to have crashes and restarts in the overclocking process itself, but during this time you are not opening multiple data intense applications, just the testing and monitoring programs, Intel Burn Test, Real Temp, CPU-Z etc. once you complete all the overclock stability testing then it is OK to open other critical applications.

During the overclocking process you experienced crashes to get there, it is always a good idea to uninstall and reinstall your graphics drivers as they always tend to get corrupted first.

To reach a 100% stable 24/7 capable CPU you have to wade through the overclocking process and you will experience system crashes to get there, those are not going to cause you to have to reload your operating system, but if you are not stable and open multiple critical files you then experience a crash or shutdown, that could result in a system reload.

That's why it is important to be running a 100% stable machine and know it is stable to be trusting your important files to.
