For dual processor, you need to make sure both processors have same stepping code as shown below:
For the E5-2683 V3 you can see that there is only SR code for your processor model here:
thank you for taking the time to answer this !
The stepping you're referring to is something different than the one shown by CPU-Z ? The ones in my screenshots do match. I'm not sure i get this right.
Could you please recommend the best way to check my processor and the one I want to buy for the stepping code ? Any software etc ?
Thank you in advance.
managed to check those using AIDA, stepping of my piece is M1.
I know stepping and CPUID are related to each other. So is it safe to assume that the one I want to buy will be compatible with mine if they share the same stepping, or sould i compare any other things using AIDA ?
The best way to check this would be physically, the SR code is on the processor itself. You may need to ask for pictures in order to compare processor stepping codes.
