IBT help

[Smoblikat]

So if I let IBT run overnight, and it fails is there any way for me to find out at which run it failed on?

If it has just stopped with as warning then you will see how far it got. If it has BSOD and shut down then no, although it doesn't really matter a fail is a fail and means you are unstable.

If it BSOD'd you have no way of knowing but if it stopped with a warning you can see the time and the last number it ran if you scrolled down.

Is this system overclocked or 100% stock? If you are failing at stock settings then it's probably due to the ram and you need to up your vtt voltage, if you are failing while overclocked you might need more vcore. Either way, sandy bridge chips don't like high speed ram so you should run more vtt voltage to get stable.

Yep, all depends just how unstable your rig is. If it is really unstable then it'll BSOD. If it is only so-so stable then it will error-out in LinX, but not crash windows, and you'll see what cycle and time it made it to before erring out.

If it BSOD's then you aren't really interested in knowing if it BSOD'ed after 5 minutes or 2hrs, its way too unstable period and needs more Vcore or something else addressed (possible bad ram, etc).

This isn't entirely true. A system can BSOD because it doesn't have enough vcore, but with just a SLIGHT increase it will be stable. For example a 2600k running at 4.5ghz on 1.365 vcore CAN bsod but at 1.37 it is 100% stable and will pass IBT/LinX for 18hrs+. A .005 up in voltage is all it took which is very slight in my opinion.

Just because it BSOD's doesn't mean it's SUPER DUPER unstable, it just means it is unstable and something needs to be changed, generally vcore/vccio - vtt voltages.

Smoblicat have you run memtest overnight to check it isn't your RAM causing the instability. My 1866mhz ram had some issues on my previous bios (had to run it on 1600) and I built a friend a rig with 2133mhz DIMMS and it suffered from random BSOD until I clocked it down to 1600mhz.

Puppies04 - You can get faster ram working with SB chips by increasing the vccio / vtt voltage. Anywhere from 1.1 to 1.2 will do the trick however 1.2 is the max I and others recommend.
