How long should I stress test my PC?

[Creed1]

Hello. I am overclocking my pc from 3.5GHz to 4.4GHz. How long should I stress test after the overclock? 

[Mira Yurizaki]

At least half an hour. Overnight if you really want to be sure.

if you want to ensure that its 100% stable

24 hours

 

 

else 

 

overnight

Depends on the program you are using I generally go a half hour for lighter OC settings and a couple for serious overclocking, usually though if it was unstable it would conk out before a half hour regardless (I use intel  XTU)

30min for the early OC stages should do fine. Go with overnight 8h tests afterwards.

Many people have successfully OCed my i5 6600k to 4.4GHz. Just to be sure, I will run it overnight.

I usually do 10 passes on Intel Burn Test (if your using an intel chip) on the highest settings, and then a 12hr test Intel extreme tuning utility. I have to make sure that my pc is pretty much rock solid because if my pc bluescreen on me while I do projects I would be so screwed.

When i used to go for absolute max on my oc's (id literally spend 30-40 hours tweaking over weeks to get that extra few mghz, i still overclock but dont take it as seriously these days) in order to claim what i consider fully stable, 12 hours in prime 95(this was a while back, not suggesting prime these days) without error.

 

I recall (this was with my old q9550 approaching 4ghz) having failures at around the 6 and even 10 hour marks and getting BSOD's on these settings on extreme gaming sessions.I thought MAYBE the oc was actually stable but failures caused by brown outs/power ripples, but crashes during gaming confirmed they were unstable!

So IMHO a couple of hours is not enough! Sure many games will run fine on slightly unstable OC, while others (high FPS seems to be a trigger) will crash almost instantly.

Ye, I use to have problem with my clocks due to brown outs to because of my AC or when my wife turns on her pc, but I fixed the problem with an UPS to counter the dips. And games and encoding/rendering things are definitely the best way to test stability.

I scored a UPS the other day for same purpose, haven't got around to getting some batteries for it yet! That being said my power is actually pretty good where i am now, probably because i have 3 phase to the premises.
