Hi all,
I've got a Xeon E5-2650 v2 and I'm looking to add a second processor to my system. I've had a good dig around this morning and even though a lot of the info I read dates back to around 2010 it appears that you have to use the same stepping when matching CPUs - is this still the case?
I see no benefit in getting any CPU other than what I already have so my plan is to get a second E5-2650 v2. However the stepping is fairly confusing - everything I read online says the stepping is only available in "M1" with S-Spec "SR1A8". When using CPUID my processor comes up with a stepping value of "4". Does this translate between the two somehow? Or do I even need to worry about the minute details these days?
Advice would be appreciated - Thanks everyone!
