Push it a bit more :0

I have allways struggled to get past 3ghz on my E2140, I want to find out what is stopping me going higher. fsb wall, volts etc.....

I hit a wall on anything above 380fsb but wasn't 100% sure if it was a fsb wall so i have tried move vcore, upto 1.55v to be exact and then wondered if it could be someting else thats the problem.

As per the overcloking guide i set the relevent voltages in bios.

Now i have been looking again in bios for the NB volts to see if that helps. I can't find anything relating to the NB voltage but found MCH Overvoltage control & FSB Overvoltage control. These were both set at 0.1 now i have upped them to 0.15 and managed to boot @ 390 x 8 = 3120mhz.

I still need to prove the rig is stable but would love a 100% overclock and the ram to run at 1:1 so two questions.

1) Is MCH the NB voltage?
2) Whats the max safe voltage i can use?

Thanks

Ok my cpu is under a Noctua / air cooler and at full load doesn't go above 60deg. I ran for 30 mins and not a problem. I realise 30 mins is not enough but after that i tried booting at 400 x 8 = 3200mhz but no joy.

At that my ram is 1:1 so its not my ram, I tried th vcore upto 1.5 and no joy so now just need to know what i can put through the NB (mch) with out damaging the board and how do i check the NB temps?

Ok 3120 stable.

Now the Nb voltage whats the max voltage for it
