6400: A1 vs. B1 stepping.

[orwell]

I saw this in an anandtech OC article http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=2802&p=3

How do I know if my 6400 Proc has A1 or B1 stepping? Is there a manufacture date or a serial No. or something that tell you?

cpuid should tell you.

Try CPU-Z (Latest Ver 1.39). Shows Stepping, Revision Plus other usfo info.

CPU-Z should tell you exactly what and how much of something you have

Look at what and How much of something I have (look at the link below)

The only production Conroes are B2 and later. If you received anything earlier then the company is ripping you off and you should contact intel directly to inform them of this.

This link shows what Core 2 Duo processors are out and the steppings that they were released at.

If I were you Id read that anand article, the one you quoted. I glanced at it and it clearly states that the PREVIOUS benches were done on A1 stepping, which was PRE-Production, meaning that you have to have at LEAST a B! or later

Hmm, I guess I should have been more precise in my language.

I have a 6400 on order, and just wanted to make sure that i was getting a B1 stepping Proc.

So, apparently any commercially available proc is B1. That is good. Question: answered.

Thanks for the answer and sorry for being imprecise

 

[pausert20]

Wrong, any commercially available Conroe will be a B2 stepping. If you receive a B1 stepping you are getting an Engineering sample.

Intel's Specfinder shows only B2 stepping for all 4MB cache C2Ds. It's not infallible though as they do leave off OEM only chips from the specfinder at times.

I got a B2 stepping E6600 ver from Newegg couple months back...
Gotta say I love it!!
Running air so far and stressing it at 8x 1:1 ratio 400MHz mem results in an impressive stable speed @ 3.2GHz 1.4volts, thermal max of 53C

Have had it stable up to 3.52GHz, but felt it was going to far... an was running volts at 1.45... since then I have found I like 3.2GHz at stock voltage best...
