Weird Athlon 64 stepping?

[billycat]

Hi I've got someone who claims he's got an A64 3400 CLAWHAMMER with.. get this...

AAARC 0346 XPAN stepping...

I've never heard of XPAN 4 letter code. He claims it's a CG revision

also he claims it's a clawhammer with 512k cache... anyone ever heard of this?

nope, I'm thinkin he can't properly read...

That is the second line on the IHS and it is simply some production codes:
AAARC - stepping
0346 - produced week 46 of 2003
XPAN - batch code
He probably has the batch code wrong and it is really XPAW.

The first line on the IHS is the product code.
There is a 512k 3400 CG Clawhammer. The product code is ADA3400AEP4AR.
