Do I have an engineering sample CPU?

[Dangerous_Dave]

I've recently got hold of a second hand Xeon E5 2650 V3 CPU, however I'm concerned it might be an engineering sample because in the CPU-ID readout it says in brackets (ES) on one of the description lines, and does not mention the full CPU name:

Everything else appears 100% retail. The lid of the CPU does not say Intel Confidential but instead has all the correct retail writing on it, including the retail code SR1YA, not an engineering sample Q code. Additionally, when I run the Intel CPU Identification Utility mentioned here:

https://www.intel.co.uk/content/www/uk/en/support/articles/000005719/processors.html

it does not give the 'this is an engineering sample' warning, but instead describes the CPU as a 'Genuine Intel(R) CPU'. Oddly, CPU-ID reports the frequency as 2.2GHz in the suspicious line, when the 2650 V3 is supposed to run a base 2.3GHz. Does anyone know what I have here?

I had an early stepping 3930k that cpu-z identified as a ES. The heat spreader was normal and these chips are soldered, so there's no chance it had been swapped.

I didn't have any problems with mine.

Possibly but I wouldn't be concerned if it's behaving properly in tests.

Old version of CPU-Z perhaps?

Bit odd in that it should show the actual model number under the name field (or at least does on the V1 E5 i've just tested) rather than just Xeon E5 V3

e.g.

It is a stepping 1 CPU, but the version of CPU-ID is I think the latest one. Not sure if it's just not being detected properly.

Might be worth going the servethehome.com forums and searching for your stepping etc. They seem to have a lot of good info about Xeons there and it's helped me out a few times

Can you post the full CPU-Z screenshot so we can see if there are any other clues?
