BSOD and C1E EIST

SlimJim1234 · 4 Jan 2012 at 16:39

Hello, i bought a bundle just before christmas pre-overclocked to 4.6Ghz.
Everything was fine initially, although this system definatly does not like my Enermax Aurora keyboard, lately i've had 3 BSOD's.

I read somewhere that when speedstep ot C1E or EIST kickes in and changes clocks, it tries to reduce voltage, and this results in a BSOD as chip is then undervoltaged.

How do i check what gave me a BSOD, and is my theory plausible?

When the BSOD pops up there will be a code usually with lots of zero's an x some more zeros and then a code something like this:

000000x00000000124 (using 0124 as example, its fairly common along vcore issues)

Fire the last 4 digits into a well known search engine along with BSOD and see what it gives you. You'd be surprised what can give you a BSOD.

In theory you could BSOD from undervolting under speedstep, but only if an offset voltage is used.

it onlt displays them for a split second, no time to read even the first digit!

I thought that fish i had in whitby last week had already passed though!

Have you tried putting it into safe mode and stressing? Just to rule out software causing it, I've had BSOD's before that were down to a bad AV update...

Right click my computer > properties > advanced system settings > "start-up and recovery" settings.... button

now under the system failure section uncheck "automatically restart"

Next time you get a BSOD it will display it untill you press the reset button

A very good tip and one I will keep bookmarked

Do this again but select also under write debugging information small minidump. next time it bluescreens it will also create a mini dump, send me the file and I will debug it for you to see what caused it.
