You still have not answered the question I've asked over and over again. I am left to conclude that the only basis for your repeated claims is your own 6400.
Here's an example: I took a quickie look at XS and right off the bat found this thread:

Now this guy is not showing dual prime torture, but he did get a 6400 to 4GHz on air at 1.54V. Not bad for 1.54V. My point is that there is info out there that's easy to find. Your 6400 is not the only one in existence.
I've personally witnessed an air-cooled 6400 running dual prime at 4GHz.
You see, this right here is the reason I am giving you a hard time. Its because your not listening to a single damn thing I am trying to tell you.
Once again! and lets hope to hell it sinks into your thick head this time :roll:
You can't answer a simple question that is asked repeatedly.
Did you see it pass 8+hrs of prime with ZERO errors? Did you see if his temps were exceeding the safe threshold of 65c after 8hrs of Prime? I seriously doubt it! as it doesnt take a genius to realize that it would be next to impossible on air with the high levels of vcore needed for stability at that speed!
And you're basing this just on your own 6400? Or are you now all the sudden gonna change paths and start giving references to other chips?
Here's what I can tell you about the air-cooled 6400 I observed at 4GHz: It had been running dual prime for over 6 hours when I stopped by my friend's lab. When I looked at the output, I saw zero errors. I don't recall the temps but I did look at them and don't remember them being freakishly high. I did take a couple of notes though - he was at 1.56V. His best CPU-Z/SuperPi for this chip on air is 530x8=4.24GHz. He puts together maybe 75 rigs a year and thoroughly benchmarks each. In the process, he comes across some great chips, RAM, GPUs, etc., that find their way into his own rigs. That doesn't really interest me (buying something someone else tweaked) but I do hit him up for some hints every now and then since he's a BIOS-tweaking maniac.
Then maybe you should stop acting like you know it all and start listening to someone who actually owns the chip and has been following it since day one.
I simply asked you a question that you couldn't hack and you lost your cool and started calling names. If you have references, you've been unwilling to give them up.
As I said before, Someone post up a pic of an E6400@4ghz on air running dual P95 for 8+hrs with zero errors and load temps under prime not exceeding 65c with a reasonable amount of vcore and then you will have something to brag about.
Did you build your CPU? No, so maybe Intel should be bragging? Did you assemble your mobo, hand-select the chips for it? No, you plugged stuff into sockets and slots, right? Did you get BIOS tweak hints online? Then what exactly do you have to brag about?
