Issues OCing my 2500K

You can do it faster...but the longer you spend testing various conditions the more you can rely on your puter not crashing.

Tricky one really, I've ran 24hrs of Prime tests with no problems only to have it bluescreen as soon as I play some music.

I tend to do an hour or so now just for temp monitoring and then if I get a BSOD under normal usage, increase the voltage slightly.

spot on

you won't be using prime95 or other stress tests in everyday usage so why spend so long testing with it?

people seem to put stress tests in the same category as benchmarks these days.

What happened was you probably were using too high a compensation for vdroop, so under load the vcore went up and kept you stable but under no load it drooped far enough for the system to become unstable. Best compromise is to use medium LLC and a slighter higher vcore than under extreme/high LLC.

Once again, its not about 'using' prime its about simulating a load that any program can potentially put on the cpu, while calculating known values to make sure its doing it right. Prime/IBT/linx are not the be all to end be of stress testing and stability but they are VERY good indicators of a stable clock.

It's set to the second highest LLC level.

1.35v for your 2500k is fine. I would not worry about that. I know guys that have used 1.5v for a year with no CPU degradation. (Though I would not recommend that 24/7 myself)

The best way I found to overclock on the Asus board is using the offset method. That way you keep the voltage very low when the CPU is not doing much work, which may be the vast majority of the time, and then a voltage increase for when it's doing some work.

This method also gives more stable voltages with it also need less voltage for the corresponding overclock.

Is the offset method where you set it at say + and then add a value like say 0.5V? Ive seen this in overclocking methods but didnt fully understand.

If I understand does this mean when my CPU is just in Windows internet browsing or idle itll run at around 1.6Ghz with a lower voltage but when gaming or underload itll also increase the voltage to the required stable voltage needed for say a 4.5Ghz therefore meaning that the system is not constantly under a 1.35V voltage like it would be if I overclock without this offset system?

Yes that's pretty much it. Though you wouldn't be using anything as high as. 0.5. You should try 0.05 and see how much voltage that goes to when you load the cores. If its too high just lower it

Also you should disable C3 and C6 power states, leave C1. If you need help with any of the other settings just ask.
