Thank you for your reply. BTW, another question, where is the data of "Stepping" came from? Is it directly read from the CPU or is it something microcode decides, or it's also looked up from the database you mentioned?
I've been having this question a long time. An ES cpu has a QDF starting with Q and a production unit has an SSPEC starting with S. This shows correctly in HWINFO. But it does not seem to match up with the "Prod. Unit" or "Eng. Sample" after it.
For example, the E5-2698B v3 in picture 2 has an...
After many resets and messing around the window fixed itself :D
For the spd it seems that on other 3647 boards like Asrock EPC621D8A the spd can't be read as well. Also the problem happens on some supermicro C612 boards as well. I think the problem come from that AST2500 super IO chip?
Shown in the pic bellow. It seems that the window size is only good for 6 cores, the rest of cores went out of the box :(
Also for some reason memory SPD information can't be detected. In fact CPU-Z can't detect it as well, got any idea about this?
