I can hit 4000 @ 50C, 4200 @ 60C, or 4400 @ 70C on my E8400 C0.

 

[freeagent]

this is the best i can do on air, with summer time temps

the voltage i had to use was intense

more then i ever gave my old q6600

wich was alot

So much voltage, CPU-Z couldn't even list it!

Additional Comment(s): Am I over Volting my unit? and is it possible for me to hit 400FSB with what I have?

Forgot to mention so far so good on stability, 40c-42c full load, Est: 1Hour

You can probably hit higher than 400 . 450 would be my goal for 4ghz

 

[nappy4]

When I up to 400MHz, it tends to not load. Would you mind giving me a range of Voltage it would be in? I'm running Corsair DDR3 XMS3 ram

That's a G41 mobo. Not ideal for OCing. You may have trouble getting to 400FSB.

You need a P45 or X48 mobo to OC that CPU well.

*Experiencing Vdroop, but bios does NOT have a LLC setting. What are my options here?*

I agree =[ but trying to make best with what I have. Other than buying a new mobo, what is the best I can do? These are my current specs. (Experiencing freezes at 100% load for about 2-3 hours in). Temperature peaks at ~ 43C. I'm having trouble figuring out the Freq/ Voltage ration.

I think you have DDR3-1333, but you are running it at 1500. Try lowering that for now. You can try tweaking the RAM later.

You basically have 3 voltage options that affect the FSB and CPU; NB Voltage, VVT, and Vcore. Keep pushing the FSB higher a little at a time until you fail P95 w/n 5mins. Then raise try raising 1 of the 3 voltages and see if it makes a difference. Rinse, repeat.

The best way to combat vdroop w/o LLC is more vcore. A high vcore at idle isn't that bad b/c there is very little current flowing. Don't be afraid to try +150mV on vcore. I doubt your loaded vcore will be dangerous at that setting.
