Prime 95 .

[Mukessh]

How many of you guys actually listen to Linus and leave your computer running Prime 95 for 24 hours after overclocking ?

[Samdb]

I'm guessing a lot.

[FloRolf]

i maybe wouldnt do it full 24h, more like 12 over night but still a long time.

[legopc]

nah when i overclock i do stress testing for a while like 1-2 hours but not 24 hours same goes for leak testing 

[boggle4321]

i dont do 24 hours, but i would leave it for the whole day, like 10 hours 

[allthatremains94]

My neighbor and I do 8 hours during the summer, we don't want the room to be hotter than it is outside.

[Art Vandelay]

I run mine for 4-8 hours with 3 minute FFTs.

[grayperview]

no its a waste of time, if your overclock isn't stable you will find out much quicker just by using the thing....

[mgsstar]

I would recommend doing P95 for 24 hours to get full stability for your pc by pressing blend and custom and putting most of your ram in. But if you are running Haswell, AIDA64 is the way to go for stability testing.

[FireFox]

I do it for between 8-12 hours with AIDA64, I don't bother with Prime95

[ProGearUk]

I only use it to test the max termos. With my setup this means up to an hour for the temps to settle at the max that they will go. 

[Gauzl]

I tested my 3770K for no more then 2 hours and it proved to be perfectly stable, though I only clocked it up to 4.2GHZ.

[Ssoele]

I don't listen to Linus, I think he is wrong, I run prime 95 + heaven in loop for 72 hours.

[Ineko]

I'm guessing a lot.

 

Seems you were wrong.

 

24 hours is a waste of time. 2 hours for me and it's into the games, if it's unstable I soon find out, and I'll be having fun whilst I do, not just sitting there waiting for Prime 95 to tick over the 24 hour mark...

[Cronus]

I'll do it overnight, or while I'm out somewhere. I enjoy using my computer, so leaving it running for 24 hours leaves me with nothing to do for a portion of that time. Most of the time you'll know if it's 24/7 stable in a couple hours anyway. 24 is just placebic.

[TheProfosist]

Been doing that since at leadt the c2d era to burn in and set the thermal compound (man AS5 takes forever). Then ill do it again once I think I have a stable OC.

[TheProfosist]

I will say 24 can be excessive depending of what percisely you trying to accomplish.

[RuecanOnRails]

A lot of hardware errors and issues often won't show up until several consecutive hours of work. Making your overclock only appear to be stable.

 

Running Prime95 or other stress tests for a full 24 hours, or over the course of a weekend will let you know if your overclock is truly stable. Just because an overclock can last an hour under stress doesn't mean it will last 2 hours or more.

 

 

A really big culprit of needing long stress tests are when troubleshooting dying ram. If one of your dimms is suspect to being faulty or dying. A stress test may not show that until the eleventh hour when it starts spitting out errors.

For all the people saying 2-3 hours is enough or that its just a waste of time, ive had an OC fail after 8 hours, i just needed to bump up the voltage just a tiny bit and it was stable, but anything less than 8 is not enough imo.

Sooner or later you ll find out if its stable, but then you wont know if its an unstable OC or anything else so good luck figuring that out

[Yuval]

I didn't OC yet, but i used prime to check my temps.

[montyrule]

nah, not me

[Nicktrance]

nope

[fishymamba]

I do 8 hours. But its not like I'm going to be overclocking ever couple of days. I haven't even gone into the BIOS in over a month. 

[Fenzee]

When I overclocked my 2500k to 4.6 Ghz, no errors showed up till 17 hours into the process.

[JesseL]

I run 12hrs.

 

While OCing my SandyBridge, and getting that stable, I found I could go 11hours consistently, but between 11-12 I will fail.

 

Why?  I dunno, but that sold me on 12hr runs.
