When do call your OC stable?
When do call your OC stable?
It depends. Lower stress levels put a lot of strain on the CPU but are fast, so you should run many cycles. I typically do around 15 for quick checks during OC, then at least 25 or 30 when I reach a final OC. High stress also heavily impacts the CPU and RAM, so it's beneficial to perform this too, though it takes longer—usually I limit myself to 10 passes.
I used to run 8 Hours Prime95 most of the time without any real issues. The Sandy Bridge processors sometimes behave oddly when overclocked with Offset Voltage. Once I tried running 8 Hours Prime95 Blend, it worked fine, but later I found it blue-screened on the internet. Now, whenever I use overclocks, I usually run 15 Passes of IBT on Max and then 2 Hours OCCT. The stability level after this combination is about 24 Hours compared to Prime95.
Intel Burn Test - 10-20 runs at full speed. Success means you're ready. No need to waste time running Prime for long periods... it doesn't add value. You can check stability in just 5 minutes with ITB on maximum settings.
I don't have specific links, but I can suggest reliable sources where you can find stress test documents.
That's a great point, Mack. I was thinking about trustworthy sources.
I don’t like making things too complicated about software.
I use Overclock Stable, just running Cinebench to check if there’s any lag in CPU rendering the box—if there is, then the settings aren’t sufficient. Then I run half hour Prime95 and ibt max 5 loops.
And after that, I try playing a 3D game for at least 2-3 hours.
Why gaming?
Because there are many cases where an overclocked CPU passes the IBT limit but struggles with gaming or even when idle.
If your settings can handle it, it’s stable enough for regular use.
It’s not worth stressing too much about your processor.
It just wears it down faster.
In today’s multicore CPUs, each core isn’t identical, so their performance varies during overclocking.
You can’t guarantee 100% stability across all cores.
Even at the default speed, long stress can cause a core to fail.
So in daily overclocking, it’s fine if two cores are fully stable, one is 99%, and the rest 95%—as long as you don’t see BSOD during your tasks.
That’s enough for stability.
Sorry for my unclear English… 😀
It's alright.
What I wrote is just my personal take.
Based on my limited experience adjusting hertz by hertz on my old processor.

Overclocking isn't really precise—many factors matter, like intuition and comfort.
Everyone has their own standard in life.
As long as you're happy with your settings and don’t get BSOD during daily tasks, you're stable.
