Oddly, Registered ECC memory (which we expected to perform the same as ECC memory) performed ~12% slower than standard memory in most tests, and almost 12% slower on the Multi Core Memory test This 12% performance drop in the Multi Core Memory is a little suspicious since it is just a little bit less than ten times the Single Core MemoryAnswer (1 of 2) Strictly, then a workstation computer is equipped with ECCram, and the CPU and motherboard is able to make use of such ram, if not, then the computer is not workstation grade computer Then the question turns to be if one needs a workstation computer for Kingston does not provide info as to whether it's ECC or nonECC I've been getting conflicting reports from Tech Support staff, Spare Parts department I still don't know what the exact configurations are for the module that is in my laptop right now and what specs are necessary for adding more memory to my system

ECC vs Non ECC Memory Thread starter macheadhigh; ECC is a logical step to parity It uses multiple parity bits assigned to larger chunks of data to detect and correct single bit errors Instead of a single parity bit for each 8 bits of data, ECC generates a 7bit code for each 64 bits of data by using nonbinary, cyclic errorcorrecting code When the 64 bits of data is read by the system, a Who Should Use ECC RAM For most gamers and general home office users, ECC RAM will not be worth the additional expense The occasional memory failure is a nuisance, but won't really cost you anything

NonECC Memory vs ECC Memory What is the distinction between ECC and nonECC memory? A nonECC memory won't do it but it does perform a bit faster, and will also be slightly cheaper An ECC memory will have more stability, and that's why it's often preferred by servers and workstations with invaluable data that users can't afford to lose, while a nonECC memory is often used in home system that needs all the performance ECC memory is used in most computers where data corruption cannot be tolerated under any circumstances, such as for scientific or financial computing Typically, ECC memory maintains a memory system immune to singlebit errors the data that is read from each word is always the same as the data that had been written to it, even if one or more
