So I just continue to read the value that represents what I input for my voltage, or the VID value.

It would if you were already running a higher voltage. If you are running 1.45V and the Vcore is spiking to 1.55V, you'd probably want to know that. Even if you are only using 1.35V and it spikes to 1.4V, you'd still want to know - or at least I would. I know what I put into the BIOS, so I don't need software telling me something I already know - I want it to tell me what the actual produced Vcore is. But that's why I use HWInfo now - it shows both the VID and the actual Vcore, so you are covered both ways.

For Ivy and Haswell I think you'll probably see WHEA errors in the error log if you check it, right around the time you got the rounding error. I'd try another slight bump in Vcore.
no errors in eventlog around that time.
i wonder if increasing the input voltage might do the trick. the current value is at 1.7V i think. cannot see the exact value anywhere.

at 1.270V Vcore, i got BSOD after 3hrs. at 1.275V i got rounding errors. at 1.280V too i got rounding errors. (but te 1.280V i set in AISuite. not sure if it really was applied. i have found it to not apply the correct settings at times). i will set 1.280V in bios and run the stress test again just to confirm.

After it reboots you should get a pop-up (once you are in Windows) about reporting the error. If you click the details button it should show you the number.

If you disable automatically restart option at the event of BSOD, the BSOD screen should show the error code.

Else, it should be there in the eventlog. Haven't needed to check there because the BSOD always showed the code. It's in Windows 8 you have to dig it up from the event log as it doesn't show a code anymore.

On mine it pops up in the middle of the screen, but you may have to have error reporting turned on. I don't remember the exact wording, but it is the "Windows recovered from an unexpected error" box that lets you send an error report to Microsoft.

Ugh. So...many...BSODs...

I think I'm just gonna make my desktop background the BSOD screen....

on my pc, when it crashed, it say what bsod is? when the pc reboot itself, and go to eventlog. I go to system . it is not there.

most of the error is, WMI. whatever that mean?

When you boot back into windows the very first time after BSOD, is there a little Windows message in the middle of the screen? If so, click the show details link. It will give you the BSOD code (like 124).
