What is the machine type number? The four-digit code in the CPUID? I am sure it is in some FM but I don't know which.

Doesn't use I/O slots. RAS: Memory protected by RAIM and ECC (internal / main memory) Re: 10 core/5.2 GHZ/14 nm Customer benefits from the overall technology i.e. latest chip design, more function on the same size chip (CPACF, Compression, cache, reduced latency between the PU/SC chips and between CPC drawers etc. Overall more performance when compared to prior generation PU chips.
