Best stability test tool?

again, another poor assumption.

8 hours prime is required.

either that or 20k on LinX or a good solid 500 runs on IBT

a comuter is not stable because it does a bit of stress.

extended stress is required.
my current cpu will do 4.6 all the time.
it does 4.8 with the memory loosened off and 5ghz with a lot of messing.

but the latter two will run for six hours max before giving up the ghost.

It's not an assumption, it's an opinion, just as yours is ;)

In my personal experience, if an o/c is stable for an hour in P95, it has never crashed randomly during day-to-day operation.
 
Let's just agree that we have different standards for what we call stable. Some guys will accept 1 hour prime whilst others will want to be sure by doing longer runs.

Personally I've had prime / linx fail several hours in so I don't accept short runs as stable.

It's probably best if you check those bsod dumps then you'll have a better idea what's causing it.

We're all kinda assuming it's the oc because you've mentioned it in your post but could also be the usual driver bsods. Check out those dumps with http://www.resplendence.com/whocrashed .

Thanks for that link. Installed and this is the result of the last crash dumps:

Error: WHEA_UNCORRECTABLE_ERROR
Bug check description: This bug check indicates that a fatal hardware error has occurred. This bug check uses the error data that is provided by the Windows Hardware Error Architecture (WHEA).
This is likely to be caused by a hardware problem problem. This problem might be caused by a thermal issue.
 
if you want to test stability properly, then there is no subsitute for Folding@home

get a big adv on the cpu and some GPU3 going on the graphics card.

if you computer passes the bigadv without crashing, then maybe you can call it stable :)

not in my experience, for instance on my system its prime/IBT/games stable all day at 3.8, run convertxtodvd and it bluescreens within seconds :)

prime to check for stability takes aaaaaages, 24 hours id personally leave that running.
 
If I remember correctly that's like bugcode 0x124? aka more vcore! Personally if I was really eager for 4.6ghz I'd start at 1.38vcore and work my way down.
 
Is there a quick setup version of folding@home by the way? Where you can just install and run a quick test?

not belittling your experience at all.

but i do happen to overclock around 20 computers a day, so i have a bit of knowledge when it comes down to it.
 
If, like these guys here, you'd like to really stress your CPU, install W7 SP1 and use LinX.

SP1 changes some registers from 128bit to 256bit, which LinX is capable of using. From what I've read, it's a temp killer :)

It is indeed very subjective! 24 hours - you're very patient :)

you need to do a bit of research into it i am afraid. the latest versions of the client are very easy to set up. no CMD prompt work, but it still takes a bit of looking into to get it set up correctly.

there are a lot of very experienced members in our distributed computing section who could give you the rundown and they are all really friendly chaps :)
 
ah I found that fast track client so I'm up and running for team 10! Don't know how to get my 5850 working yet though.
 
I would say the following (in the following order):
1. Intel Burn x 20 on extreme, max memory.
2. Prime95 large ffts (20mins - to workout max cpu temp).
3. 1 Hour Prime95 Blend (the real test).

Then your pc may be stable, I've still had crashes after this though... You have to find a balance between stability and benching your cpu into the ground.
If your folding with it all day then an 8 hour FFT/blend run will be beneficial to test if your stable over long periods of time.
If your just gaming then the above will be fine, followed by some extensive "testing" (gaming) in the games that you plan to play...
 
-50-52 passes of IBT on custom and selecting free ram for cpu overclock stability

-10 passes of memtest86+ for each ram stick for ram testing

-10 hours of Prime95 Blend test to test overall system stability (cpu+northbridge+ram)

- 30mins of Furmark if stress testing gpu overclock stability.
