Got my E6420 - A1??

Knight3539 · May 10, 2007

Okay, got my E6420 today. Here's what it says:

FPO/Batch: L709A170
Pack Date: 4/18/07

Ummm, okay. So what's the A1? Won't be able to OC it 'til next week when my PSU gets in.

L7 = year 2007
09 = week 9
A = "A stepping"
170 = batch #

E6420's are quite good OC'ers because they'r Conroes and not the slightly worse Allendales.

Thanks for that. I was trying to find exactly what that meant. I thought all the 6420's were supposed to be B2 stepping based on Intel's info:

The "A" in the batch code is not the stepping. It's just some sort of production code. The main thing is you have a week 9 of 2007. It should be a good overclocker.

Does anyone know yet how the new L7 steppings overclock?

I just got a L701C326 e6600 yesterday. I'm hoping to get everything put together this weekend, then start benching & overclocking after that.

They aren't steppings :bang head

Sorry just a pet peeve of mine to call the batch codes steppings

Iirc the letter is a production code like batboy said which notes the manufacturing location.

batboy · May 12, 2007

Well, to be technical, the first letter is the location code (L=Malaysia). The second number is the year (7=2007). The third and fourth numbers are the week (09=week 9).

So my L646G523 was made in Nov. of 06?

MadMan007 · May 12, 2007

Thanks batboy. Found this because it was bugging me to know what the 5th character is:

1st letter or digit = plant code (Malay)
0 = San Jose, Costa Rica
1 = Cavite, Philippines
3 = .............., Costa Rica
6 = Chandler, Arizona
7 = .........., Philippines
8 = Leixlip, Ireland
9 = Penang, Malaysia
L = ............, Malaysia
Q = ..........., Malaysia
R = Manila, Philippines
Y = Leixlip, Ireland

2nd digit = Year of production (2001)

3rd & 4th digits = week (49th week )

5th - 8th digits= lot number

It's part of the lot number then...not sure what that means exactly. Maybe which wafer it came from?

The week 46 of 2006 is Intel's fiscal year 2006 week 46. I don't remember exactly when their fiscal year begins, but I was thinking maybe February 1st?

downer · May 12, 2007

Is there any store people seem to have the best luck with good steppings for the E6420? Looking to purchase one in the next couple days.

batboy · May 12, 2007

There is only one stepping for the E6420.
