need help with overclock fail (blue screen)

post #1 of 5
Thread Starter 
Hi
i have my CPU overclocked to 3.8GHz and trying to get to 4.0 GHz using this guide http://www.clunk.org.uk/forums/overclocking/22106-core-i7-overclocking-guide-beginners.html
it says to set the DRAM Bus Voltage to 1.66 but when i do that i get a warning that it can cause permanent damage to my cpu....
i had it set to 1.64 instead.... anyway everything loads up i open coretemp and open prime95 run a test and after a few seconds i get these two loud beeps that manage to scary the crap out of me each time... tongue.gif then i get a half black half grey screen then a blue screen with lots of errors.
i tried setting the QPI/DRAM Core Voltage to 1.31 and still after that it didnt work .... i didnt try to increase the cpu voltage because in the guide it says that 1.25 is the max i should go.....
what do u guys think ?
im doing this on air ...
Thanks

newbie here too, but from what i learned, oving aint a cookbook style thing to do. 'put this value in here and that there' aint gonna work. try 190x20 1.3v (cpu vcore) and rest to default value. worked for me. and get the ram clock speed down. your fsb will up it for you.

I don't specifically remember those suggestions in the clunk guide as I followed it. Leave your ram settings alone except if you have MP ram enabled XMP in bios and set your dram voltage at manufacturers recommendation. Adjust your vcore voltage to then overclock. If you read any posts on here you would know that going over 1.25 is not only ok but expected. 1.4- 1.5 could be you danger zones. I've seen several here set at 1.35 for 4.5-4.8 overclocks. If you don't have realtemp, download it to keep an eye on your temps. i.e I am 4.5 at 1.27v and temps at full load around 57-63.

i set my DRAM Bus voltage to 1.6V .... because i saw my ram had 8-8-8-24 1.6v written on it....
and ofcourse increased my VCore cpu voltage
