Long term OC stability?

[CostcoSamples]

I find my system always has occasional glitches such as freezing up after a week of leaving it on and putting it to sleep when not in use.  Once in a while a program will lock up, or windows becomes unresponsive.  Stress tests (PRIME95) run fine over 24 hours.  This even with a modest OC with extra voltage.

 

I love the extra CPU speed, but I'm not willing to sacrifice stability.  Is this normal?

 

Anyone out there running a permanent OC with no issues at all?

That's probably just Windows issues, rather than OC issues. OC issues would be sudden crashes and shutdowns.

all my overclocks have a combo between performance and stability. 4790k in my GF's dad's pc is running 4.5 GHz 24/7 no hiccups and my old 2500k is still rocking 4.8 GHz after all this time.

Here is a good way to test. Disable fastboot in windows and always shutdown rather than sleep or hibernate. I am willing to bet this will stop all those glitches.

I run nothing but overclocked and have yet to experience any random glitches as a result of the overclock.  I use adaptive voltage and all CPU power savings features along with those in Windows.  I suspect that you may have a memory or OS related stability issue.

Overclocking always introduces some instability.  For example I commonly have issues with Overwatch where when I exit the game it will "crash" rather than shutdown properly. 

 

If you want a perfectly stable system, you have to settle for stock settings.  The more you overclock, the more instability you introduce.  Sometimes said instability is negligible and you won't notice it.  Often with overclocks over time as your components degrade (especially with higher voltages) it can become more and more unstable all the time.

 

Usually when people are overclocking I recommend them finding an OC that doesn't crash, using it during their daily routine and seeing if they have any problems because for most people if it runs well for what they use their PC for it doesn't matter if the chip overheats under prime95 or other heavy stress tests.  If you're worried about remaining stable over a week, you should really just be running stock or a relatively minor overclock. 

 

It's also worth noting that sleep mode/hibernate really doesn't play nice with overclocking most of the time.  Depends a lot on the motherboard.
