Intel CPU Stepping Question

Hi,

I have the following string to identify an Intel CPU:
EM64T Family 6 Model 15 Stepping 6 2660 MHz (I think it's from the
Windows Registry)
Additionally I know that the CPU is a dual core XEON processor. I
would like to identify the CPU. I'm using this tool:
http://processorfinder.intel.com/List.aspx?ParentRadio=All&ProcFam=528&SearchKey=
But now I'm stuck with these 10 selections. Is there a way to
translate the "Stepping 6" from my CPU ID to the stepping selection on
that Intel website?

Any help would be greatly appreciated.
Sebastian

P.S.: I have no access to that system any more, all I have and can get
is aforementioned string. I need it for documentation purposes.

Go to

http://processorfinder.intel.com

Select "server", then Xeon from the menu. Select 2.66GHz for
the frequency. Set cores filter to 2.

There are about five processors meeting those criterion.
This one is an example of one of them.

Paul,

thanks for your prompt answer. I did what you describe already and I
get about 10 processors. That was why I asked about the stepping. To
narrow the list down I thought it would be possible to translate my
stepping 5 to stepping B3 or something like that.
I actually thought the URL I posted would already contain this
selection but apparently it does not work that way.

But thanks anyway, I appreciate the effort :-)

Algorithm -

Take this:

Family 6 Model 15 Stepping 6

Convert each number to hexadecimal. 15 = F in the hexadecimal system.
Concatenate the numbers. This gives 6F6.

The 6F6 type number is present in each individual processor entry.
It is not listed in the table form. In the example here, you can
see the match for 6F6.

http://processorfinder.intel.com/details.aspx?sSpec=SL9U2

Now, go through the Xeon table, clicking all the 2.66GHz processors
with two cores. Five of them match 6F6. Read out the stepping on
each page, and see if they are the same. In the example above,
it is "B2".

HTH,
Paul
