I AM ASKINSG REGARDING THE DIFFERENCE BETWEEN ECC AND NON-ECC MEMORY, AND IF THERE AREANY MAJOR??AS,
THIS PARTICULAR QUESTION IS REGARDING MY NEW HOME COMPUTER,LONG OVERDUE WITH ALL THE POSSIBLE FEATURE ,SOUNDSYSTEMS,DUALHARDRIVES,FASTEST BURNERS DVD AND CD IN THE EAST COULD BY AND ANYONE WHO KNOWS ME KNEW I WAS WELL OVERDUE FOR THE LCD FLATPANEL ANYWAY THE ISSUE AT HARD RAMBUS AND THE MEMORY, ECC OR NON-ECC WHICH IF I AM OT MISTAKEN STAND FOR ERROR CORRECTING CODE, WHICH I HAVE NOT SEEN ON ANY OTHER PC MEMORY CHOICES ONLY ON RAMBUS,NOW IT SOUND IMPORTAN AND THIS IS THE PART THE GETS ME IF IT IS ,HY WOULD THEY MAKE IT AN OPTION,EXCUSE NAIVEITY, OF COURSE $$$$BUT ANY OTHER VIABLE ANSWERS WOULD BE APPRECIATED THANK YOU FOR YOUR TIME MICKY AS I AM EXTREMELY INTERESTED AS I PLAN TO AMKE THAT MY NEST PURCHASE
THANK-YOU AGAIN MICKY

ECC is a data integrity method that is used in high-end PC's and file servers,it can detect and correct errors,memory and system boards chips have become more updated.
Non-parity systems donot perform integrity checks,and there fore does not need the parity check to which reports a host of problems.
Does not apply to Rambus

Here's part of an article on the subject.

If you are building a PC and deciding which type to use, the following guidelines should help. If you plan to use your system as a server or a similar mission critical type machine, it is to your advantage to use ECC. If you plan to use your PC for regular home, office, or gaming applications, you are better off with non-parity.

ECC (error correcting code) memory performs "double bit detection and single bit correction." This means that if youhave a single bit memory error, the chipset and memory will find and repair the error on the fly without you knowing that it happened. If you have a double bit memory error, it will detect and report it. Using ECC decreases your PC's performance by about 2%. Current technology DRAM is very stable and memory errors are rare, so unless you have a need for ECC, you are better served with non-parity SDRAM.
