Q9450 OC / Temps / Settings

Anyone... what is the general consensus on the highest 24/7 volts on high end air????

[Gen]

i don't have a 45nm quad but intel states max VID is 1.3625v. i would not go over 1.4v load, 1.4v vtt or 1.4 pll on any 45nm chip.

Ok, Im under the voltage on idle and load. VTT is 1.4 from 1.3 stock (not sure if I can lower that or not, I will have to check stability). And I dont believe my bios/mobo has a 'pll' option (or its not named pll).

So 1.4 is the highest 24/7 voltage (to get 2 years out of this chip possibly).

Just noticed that post now sorry. I have to post as my goal with such overclocking is not the same than for everybody.
"To get 2 years+" with the current Bios we get, I would stay at 3.6GHz for sure.

I only plan to keep that processor & motherboard for one year. They both can die if Nehalem motherboards, processors and cheaper DDR3 is out: I won't mind at all.

I hope we will get an improved Bios for X48 chipset where we can lower the VTT voltage but till then, I had to make that more clear.
It is true that applying over 1.45V to a CPU or VTT with 45nm technology will reduce the lifetime of your system.

Edit: "PLL" is a different story. The lowest manual setting in the Bios is 1.50V. It is suggested not to go above 1.60V for that setting.

make sure your mobo isn't overvolting as well, P5K-E overvolts PLL 0.08v making 1.6v = 1.68v

On water it's a 24/7 system @ 3.8GHz now for me after hours and hours... of stress testing /zzzZzz

High end air is not far from my water system.
It depends a lot on the cooling on the N/B too.
But 3.8Ghz too I guess.

Anyway, besides world records or such I don't see the point to go to 4GHz+ when we are already lucky to have a 100% stable 3.8GHz while staying in safe voltage ranges.
I burned too many boards and too many RAMs. I don't want this to be the first processor I burn
