Ram non ecc what is

It is similar to Parity, but more advanced. It can detect multiple errors in data returned from memory and actually correct a single error. The system board to be used must support ECC, and all of the memory in the system must be ECC for it to be actively supported.

This article is part of the Tom's Hardware Glossary. Scharon Harding has a special affinity for gaming peripherals especially monitors , laptops and virtual reality. Previously, she covered business technology, including hardware, software, cyber security, cloud and other IT happenings, at Channelnomics, with bylines at CRN UK. Scharon Harding. Therefore, ECC memory sticks are more expensive than ordinary memory. ECC memory is usually used in servers or graphics workstations.

Guaranteed data storage and accuracy of reading and writing. Server memory and ordinary PC memory are very similar, there is no obvious difference in appearance and structure, but its price is higher than ordinary memory. With the time goes by, server uses some new technologies now, such as ecc, chipkill, register, hot swap technology, and FB-DIMM full buffer memory module etc. Generally, there is only one, which can adjust the clock signal and ensure the signal synchronization between the memory modules.

The smaller IC chip pieces at the bottom plays a role in improving the driving capability. Server products need to support large-capacity memory. The motherboard alone cannot drive such a large-capacity memory. Instead, the memory module with Register is used to improve the driving ability, so that the server can support up to 32GB of memory.

Because of the PLL and Register chips, the server memory capacitor can be made very large, it can better meet the endless requirements of the ever-increasing software for memory. RECC has one more register.

If the data wasn't properly written, the extra chip will correct it in many cases depending on the type of error. Non-ECC also called non-parity modules do not have this error-detecting feature. Any chip count not divisible by three or five indicates a non-parity memory module.

Using ECC decreases your computer's performance by about 2 percent.
