Because ISSS is Windows XP system, support only memory 3.2 maximally, so it usually encounters the problems which the computer is died or gives error when programming for the reason without enough memory.
But ISPS is programming Server, 3.0 iBase Vesrion, with I5 CPU and 8G memory. And ISPS uses Win2008 server system, can support 32 memory maximally. In the future, BMW will use ISPS to replace ISSS completely.
