I've purchased a (probably not new) Barcelona 2346 1.8 GHz CPU. I swear this is the last time I'm buying from a 3rd or 4th tier vendor to save a couple of bucks. Reason? It didn't arrive in the AMD PIB packaging.

Just below the AMD logo is this "2006 AMD". Is this chip soon to be 3 years old? I have a hard time believing that the processor sat on a vendor's shelf for the last couple of years.

Here are the other numbers:

AMD Opteron
OS2346PAL4BGH
GAAHB AA 0813MPMW
9537729E80020

I've tried to find info on the AMD main site as to how to read this but can't find anything.

Any help on this will be greatly appreciated.

ahh, the stepping code . . . let me check that the net for the latest. Just to be clear, once a chip is made with a particular stepping "version" (i.e. "stepping code") it can't be changed in any way, correct?

Another overview:
http://www.chiplist.com/AMD_Op...3f-subsection--2294-/

The "2006 AMD" is a copyright notice, not the introduction date of your CPU. As you can see in the overview, yours was introduced in September 2007.

I don't know by heart, but I think the 0813 might be the year and week number of your processor.

from here

so no the Introduction date of this processor according to this is April 9, 2008 so this processor is just over 14 months old not to shabby will still hold its own i take it you got a decen price when you brought it ?
