how to tell the difference btw AMD Athlon versions?

[Digga]

EDIT:
ah, I guess you can tell the difference by the voltage.
the EE version is labeled for 1.2 to 1.25, while to normal, non EE version is >1.3.
am I correct?

introduction:
I set up an AMD based system some time ago, including an Athlon 64 X2 3800+ EE (socket AM2).
I wanted the EE version and I assumed the dealer got me just that. however, I'm not too sure that the CPU actually is the EE version.
I'm planning to the sell the whole rig in the near future, so I tried to validate whether the CPU is EE or not.
it wouldn't really matter much for the end price, but I'm just curious.

question:
so I fired up CPU-Z, assuming that if it's the EE version, the program will label it as such. is that the case? because it's not labeled as EE.
so my question is, how can I easily verify if the CPU is EE or not?

I don't want to unmount the fan, as it was a PITA to install, so checking the product number unfortunately is ruled out.

info:
here is what CPU-Z and SIW had to say:

You may like to try the AMD CPU Information app located here:

I don't think AMD's CPU Info app will tell you what you need to know.

Download AMDClub's Central Brain Identifier here: http://cbid.amdclub.ru/files/cbid83b.zip

Then stick the OPN# at the end of this URL and you will know which CPU you have (if it has a Thermal Design Power of 65W or 35W it is a EE):

thanks for the suggestions.

Odd it shows up just fine on my 4800+, try downloading the Everest trial (http://www.lavalys.com/products/download.php?ps=UE&dlid=35&frm=0&lang=en) and checking under Motherboard>CPU>Maximum Power and Core Voltage. It should be something like 65W Max Power and 1.2V Voltage.

Anyways considering it is running at 1.2volts it is most likely a 65W EE processor (http://www.amdcompare.com/us-en/desktop/details.aspx?opn=ADO3800IAA5CU). If you are really curious you can just take off your heatsink and read the OPN number off the CPU.

Anyways considering it is running at 1.2volts it is most likely a 65W EE processor.it most probably is I'd guess, yes (see my edit in the first post).

If you are really curious you can just take off your heatsink and read the OPN number off the CPU.I'm not that curious, no :-)

Yours wouldn't happen to be an engineering sample, would it? Quite a few tools have trouble identifying them, from personal experience (my current merom was pre-release) and lots of reports on enthusiast sites.

I wouldn't really know though, I did buy the CPU in a small computer store where I live as a tray version (i.e. not boxed). there wasn't any talk about it being an engineering sample, I just ordered a plain 3800+ EE and I supposedly got that (I hope).
all I remember from the package is that it was produced in 2005.

I'd guess that some engineering samples would be rather unstable, is that the case?
the system is running quite fine, I had 3 or 4 bluescreens though with the error message (WinXP):
BAD_POOL_HEADER
STOP: 0x00000019 (0x00000020 ...)

that would most likely indicate a driver problem or maybe faulty RAM if my research is correct.
I haven't yet come around to rule out any of two though.

is there any way to check if it's an engineering sample or not, without removing the fan?
