So what voltage is everyone running their 6400 on? What are your temps at that voltage?
 
My e6400 is at 2.72ghz w/ only 1.200v - 8hrs orthos stable

idle: 46*C
load: 55*C

I have a feeling that I could probably drop the voltage further and run it at 2.8ghz but I'd rather not mess with it since I'm happy with the overclock :)

On a side note when I was letting the bios set the voltage which it set at 1.425 @2.66ghz. I got:

idle: 55*C-60*C
load: 70*C-74*C
 
Definitely watch out for the AUTO CPU voltage setting with the Gigabyte DS3 and likely the S3 as well. When you start overclocking it gets a little too generous with some extra volts to insure stability.

I was able to get 3300 MHz out of an E6300 at a default of about 1.325 volts under full Orthos load. Temps under load were in the low 60s with the Intel heatsink / fan.

You should be able to get the majority of the possible performance out of a C2D without having to go beyond 1.40 volts when air cooled.
 
Yeah when it was on auto, my load temps were like 70°C. I am running 3ghz on 1.3625. I just did not know how low to run my voltage. I guess I will have to try lower voltages. But now it is running a lot cooler than it was doing...

what mobo are you using? Anyways try lowering your voltage to 1.300 then if its stable try 1.25 even though I made the jump from 1.285 to 1.200 with no problems :)

That's what happened to me when I updated to the F6 bios so I simply went back to F3 where that feature had not been implemented and twas' all good :)

You can probably run 3 GHz at 1.30 volts.

Check it with Orthos to make sure you haven't lost stability. Your load temps should drop to a lot less than 70C at this setting.
 
2.56 GHz at 1.10v

Idle: 36°C
Load: 49°C

Ambient: The thermostat downstairs says its 18°C, but it's a bit warmer upstairs in my room.

My e6400 could probably be overclocked even higher at this voltage, but it's already fast enough for my purposes. ;) Cooling is a Scythe Ninja with a Yate Loon D12SL-12 running at 5v. All other case fans are running at 5v.
 
Right now I am running 3Ghz at 1.3v. My temps are 45°C Idle and 58°C Load. I am using the eVGA 680i....

damn, 18C ambient... i have to deal with 29C ambient.

3.2ghz at 1.248V

idle: 47C
load: 58C

22C ambient
idle: 36C
load: 47C
