Hey 8 :)

I know you're not a firm believer in running Intel Burn Test and stuff for stability but is there a particular reason?

Surely if a chip can do infinite loops at stock it should be able to do them when overclocked too?

Asking because I can get my 2600k to pass Linx at 4.8Ghz at just over 1.4v

I can get into Windows and do pretty much every at 5Ghz with 1.45v but it will not pass any stress tests.
 
A stress test typically only tests a CPU's ability to function in a specific way or a small range of tests and doesn't fully represent every day use.

However I find it a good way to save myself from potential data/OS corruption, etc. while finding the stable point that could otherwise result in spending a lot of time reinstalling the OS and/or recovering from backups/problems down the line. Once its given me a feel for the CPU's stability I can then narrow down where its likely to be fully application stable.
 
Running endless loops of p95/ibt/LinX., only proves your system can run them. Fire up a game, bf3/4 or crysis 3 are good examples. Ive had them fail on the load screen but stress stable. The unrealistic heat they generate is another matter. For the cpu i find a couple of runs of asus real bench works well. Ok on ram too as ive found this week. Bumped my 2400mhz kit up to 2600mhz.
 
You need to stress the PC in the way you would normally use it. setter is along what I consider the correct lines. Game/encode/browse/unpack/ Move large files etc .. Normal stuff!!!
 
can you pass a run of real bench 2.0? i'm using this for quick test when testing out different clock speeds it will find an unstable clock pretty quick even in a quick test.... and then pretty much was setter has already said bf3/4 and crysis 3 will find an unstable clock after a few hours of playing.
 
Ive been trying a few different settings for real bench.

4.5ghz cpu, 1.267v
4300mhz cache, 1.25v
2600mhz ram, 1.75v
11-12-12-32-193 2T
ioa, 1.25
iod, 1.25
sa, 1.25

The above completed 2 loops without issue but failed on super pi 32m with a rounding error, bsod on 0x50 when shutting the system down. Im gonna see if i can get the ram running 1T, same voltage but timings at 9-12-12-25-196
 
hi setter i noticed you have the same cpu + mobo as me, just a quick question, does your pc ever fail boot the first time and then immediately boot up again?
 
Never had that on the current board. But did on an asus x58 p6t deluxe v2. Otherwise it ran fine, i7 920 @4.2ghz.
