@MichaelKjörling Data integrity at that level is not critical in home-use applications. Parent applications (or the OS) can handle that easily, and ECC memory comes with a small performance overhead. Additionally, virtually all consumer CPUs do not support ECC memory (thus the should). - WannabeCoder Mar 25 '15 at 15:36 Do you feel the improvements of ECC memory compared to non-ECC ones? Question in post: Do end-users really benefit from using ECC memories that much? Do you feel and really benefit meaning should he care or is it irrelevant Error-correcting code memory (ECC memory) is a type of computer data storage that can detect and correct the most common kinds of internal data corruption. ECC memory is used in most computers where data corruption cannot be tolerated under any circumstances, such as for scientific or financial computing
. It's important to know that ECC memory and non-ECC memory cannot be. ECC RAM is very popular in servers or embedded systems with high-value data as it serves to protect against data corruption by automatically detecting and correcting memory errors. ECC vs Non-ECC RAM. Non-ECC Memory utilizes a bank of eight memory chips, in which data is stored and provided to the CPU on demand ECC modules can be used on either a non-parity/non-ECC system, or on a system that supports ECC. The ECC module *cannot* be used in parity mode. The reason for this is simply that the ECC module design is such that individual parity bits cannot be set, so the chipset will not write the correct data to the chips which contain the ECC word ECC stands for ERROR CORRECTING CODE. This uses technology on the motherboard to test the accuracy of of outgoing and incoming data by using a checksum. Some errors are automatically corrected, ECC modules are normaly used in high end workstations and servers where data integrity is vital. ECC applies to DDR, DDR2 and DDR3 modules
Using ECC adds another layer of protection to storage, so when combined with ZFS it greatly increases data integrity. In fact if you go look at every Sun server and appliance they sell, they all come standard with ECC memory. When it comes to the utmost reliability of data, cheaping out and using non-ECC is just installing a weak link Kingston KCP424SD8/16 16GB DDR4 2400Mhz Non ECC Memory.

ZFS w/o ECC RAM -> Total loss of data ECC vs non-ECC RAM and ZFS: present a study of the effects of disk and memory corruption on file system data integrity. I still do not have any statistical answers to ECC vs Parity vs Non-ECC Non- Parity memory types. The order listed is slowest to fastest. But it is hard to tell the difference to the human eye just like 219fps vs 220fps. Humans cannot differentiate between a fraction of a nanosecond. Any more questions In the field, the failure rate for non-ECC Kingston RAM is only about .4%, or roughly one stick for every 250 sticks we sell. So while ECC RAM is certainly important for servers and systems with high-value data, non-ECC RAM is more than stable enough for use in most home or work systems Once the ecc_check.c file is copied to the desktop, enter the command CD Desktop into the terminal to change the active directory to the Desktop which is where the ecc_check.c file is now located. Next, compile the file with the command gcc ecc_check.c -o ecc_check. You will get a few warnings, but they are expected and completely normal 4. There is no right and wrong with this ECC vs non-ECC. There's good and better. The question is where do you draw that line and what makes you think good is good enough for your situation. The whole reason I advocate for ECC RAM is because I don't think people realize how serious things get when you don't know how bad non-ECC RAM.

ECC more expensive than Non-ECC, but not all motherboards support ECC ram. check with your Motherboard manufacturer before purchasing Ecc Memory. It's often used in high end systems, or servers. Unbuffered non-parity is the stuff that we usually use. ECC RAM is generally only used in servers to ensure data integrity. These days RAM is reliable enough not to need it for normal usage. ECC also takes a minor hit to performance; I don't think the additional costs are worth the gains in a non-server environment ECC is used in NT servers for stability and data integrity, you'll usually see that 9th chip on there which runs the extra parity check. You don't gain performance in speed at all, just stability, and they don't like to be overclocked past spec, so it's not good for gamers really, they're mostly for servers
I agree with the primary thrust of the debate over ECC vs Non-ECC memory. I like ECC memory because it removes the potential issue of memory errors leaking in. My desktop, for instance, has ECC memory (with an AMD consumer processor, I wasn't too crazy then) so that any work I do with software won't have random failures Kingston KHX1333C9D3B1K2/4G Hyperx DDR3 Sdram Memory Module, 4 GB - 2 x 2 GB Storage Capacity, DDR3 SDRAM Technology, DIMM 240-pin Form Factor, 1333 MHz - PC3-10600 Memory Speed, CL9 Latency Timings, Non-ECC Data Integrity Check, Unbuffered RAM Features, 2 x memory - DIMM 240-pin Compatible Slots, 256 x 64 Module Configuration, 1.5 V Supply Voltage, UPC 740617174533 (KHX1333C9D3B1K24G.
