Max Vcore on E6400

What would be the safe Max Vcore for this chip, on good air cooling, say TT120 flat out ?

It depends on your temps

Yep, air you will be limted by temperatures, not voltage.

Well i got to 3.6 GHz on my 6400 with these temps but it was at about 1.49odd volts in the bios, and wasnt stable for more than a minute, would increasing the Vcore to 1.5v help and be safe :confused:

or does the stability problem lie elsewhere ?

Maybe the chip is getting to hot, adding vCore only make this problem worse!

46C has plenty of head room, have you made sure your RAM is stable at that clock speed?

I have Ballistix PC6400C4 and loosened up the timings to 5.5.5.15 for that run, was hoping it would cope fine at that tbh.

Could it still be the RAM thats an issue or any other setting that might not be correct ?

Where are u getting 46°C from?

That screenshot above shows 35 seconds of a stability test, hardly enough time for the cpu to hit its max load, The OP should press both the Start buttons on TAT then he would get a proper load temp, got a feeling thats gonna hit 60°C which is too hot for the chip to produce a nice overclock.

Yes temps would be much higher i think.

The problem is its not stable @ 3.6 I'm wondering if its possible for me to get it stable @ that by adjusting somthing I've set incorrectly or forgotten ? and also If going more than 1.49v Vcore would help and if its safe for me.

Thanks all

post a pic of temp after 10 mins of orthos ?
