I would guess that "NP" here stands for "non-parity". Non-parity RAM makes no attempt to detect memory errors, while ECC (Error Checking & Correcting, IIRC) detects memory errors and can sometimes fix them. Traditionally, PCs have used non-parity memory and "serious" computers have used ECC, but now ECC is starting to move into the PC market as well. -- That's not gibberish...
