Default What's the best batch code of E8400's?

Hey guys, if you want to post your batch numbers here and Highest stable OC, I'll keep them in post #1 for quick reference. We'll see how the batches hold up to the OC's.

Intel CPU Info
Detailed Info

Here is a great thread by linskingdom on 45nm processors.

I believe this is a record!!

For those with temperature/voltage questions or issues with these CPU's, you might wanna read the following:

My Personal Proof that the Core Sensors are off
e8400 Overheating
Flawed Core Sensor Diode
More Core Sensor Diode Info
Penryn Delay Due to Core Sensor Diodes??
Link 5 (read through)
Tricky's E8400 "Crapped Out"

How To Properly Apply Thermal Compound

Please note, that by sayiing "Official" below, I don't mean that it will be published worldwide on any websites or anything like that, it's just my way of saying thanks for posting your OC's here!

Enjoy!!

I don't get as lucky as some people, 1.3V 4.0ghz. Maybe my RAM is holding me back.

4.0GHz at 1.32v is better then most. I've seen on average 3.8GHz with 1.35v.

So far from the posts I've seen here on OCN 4.0GHz very likely. Some have reached up to 4.3GHz.

I am just curious, what is your guys' NB Voltages? Is it good to raise these when you overclock?

If Intel is anything like my AMD system, it definitely won't hurt to try. Some like it, some don't. (I'm totally new to Intel)

Yeah when getting a high FSB it's a must. to make 500fsb stable I need 1.7v on the NB.
