On the intel website, the max voltage for the E6300 is stated as 1.35v, but I guess that's not the "real" max voltage...

How do I know when I'm reaching a dangerous voltage? And what voltage should I keep as my maximum when I try to overclock my E6300? The DS4 guide says to increase "VCORE to 1.45v - Please be aware that this will increase temps!" ... Is that the maximum I should increase it to? Obviuosly I don't wanna burn out my E6300!

Also my ram (Kingston HyperX 800Mhz CL4) is quoted as
"Power supply : Vdd: 1.8V ± 0.1V, Vddq: 1.8V ± 0.1V"
But on the same data sheet, it says
"Timing Reference: 667MHz 5-5-5-15 at +1.8V / 800MHz 4-4-4-12 at +2.0V"

So I need to put it up to 2v to get it at 4-4-4-12? What if I overclock and the computer won't post or something, as the ram is already at 2v would it be too risky to try and up the ram voltage slightly, say to 2.1v?

If I encounter problems, what other voltages should I be aware of and should I try increasing on a DS4?

Also, a couple questions regarding the DS4 guide... I like to know why I'm doing things rather than just do them blindly :D

MCH Voltage to +0.1v <-- why? And what is MCH voltage?
FSB Voltage to +0.1v <-- why?
 
You can't go too far wrong with voltages. Just increase them a touch, benchmark & watch the temps :) 1.45-1.50 on a Conroe with good cooling would see it reaching it's full overclocking potential. Again with memory it will need boosting to reach higher speeds and/or lower timings.. upto 2.2v is fine with some air movement over the motherboard generally to keep things cool :)

Although a different model motherboard, you may find this helpful :cool:
