    Here are a few simple steps that should help you fix your ECC memory error problem. Answering the exact question “What is ECC memory?”, ECC RAM or error-correcting RAM is a special type of memory space that detects and corrects the most common errors that could otherwise lead to data corruption or system crashes. These are called single-bit misses and require an explanation in their own right.

    Error-correcting code memory (ECC memory) is an absolute type of computer storage that uses an error-correcting code[a] (ECC) to detect errors. in case of true corruption. happens in memory. ECC memory is used in most methods where data corruption is in no way acceptable, for example,

    Normally, ECC memory supports a one-bit error protection system: individual data read from a single word is always the same, given that the data was written to it, even if it is written along with it. saved bits are set to the wrong state. Most non-ECC storage devices cannot detect errors, but some storage devices Non-ECC with parity support allows detection but not correction.

    Description

    Static ECCs protect against undetected memory number corruption and are used on workstations where such corruption is unacceptable, such as some scientific and low-cost applications, computers or databases, and file servers. ECC also reduces ongoing downtime, which is unacceptable in the first place for multi-user server products with maximum uptime and systems.

    Electrical or magnetic interference in a computer system can cause one bit of random-access memory (DRAM) to jump to its opposite state. At first it was thought that this was mainly due to alpha particles emitted by particles in the chip packaging material, but data has shown that most soft point errors in DRAM chips are due to the ability to emit, mainly neutrons, due to Jimmy. cosmic secondary, which can change the information of one or more memory cells of the body orbreak the schemas used to read or write to actually read it.[2] So the error rate increases slightly with height; for example, the cyclic neutron flux studied at sea level is 3.5 times greater at 1.5 km and 300 times better at a cruising distance of 10-12 km (commercial aircraft depends on altitude).[3] As a result, devices operating at high altitudes require particular deployment reliability.

    For example, the Cassini-Huygens spacecraft launched in 1997 contained identical black boxes, each with 2.5 GB of commercial DRAM hamburger-style memory. Thanks to the impressive built-in EDAC, the spacecraft’s technical telemetry reported errors of one bit per word (correctable) and even errors of two bits per word (uncorrectable). During our first 2.5 year flight, the familiar spacecraft had an almost constant single bit error rate of about 280 errors per day. However, on November 6, 1997, during the first month of being in space, this number of failures more than quadrupled.and became unique for this day. Was it related to the solar particle event detected by the GOES 9.[4] computer?

    There are concerns that many DRAM chips will no longer be exposed to this form of radiation as DRAM density continues to increase, resulting in smaller component sizes on the chips while operating voltage continues to drop, often due to lower power particles will be able to improve the state of the memory cell.[3] On the other hand, smaller cells represent lesser known targets and are moving towards technologies such as SOI. Individual muscles may become less vulnerable. , counteracting this trend, or perhaps even reversing it. Recent studies[5] show that single cosmic ray interferences are markedly reduced with the previous process geometry, and concerns about increased bit cell error estimates are unfounded.

    Works published between 2007 and 2009 showed very different error outputs with a difference in characterMore than 7 orders of magnitude in the range of 10 to 10 errors/bph (about 1 bit error hour per gigabyte of storage). ). 10–17 errors/bit h (approximately one bit error every 100 years per gigabyte of memory).[5] [6] < sup >[7] At SIGMETRICS/Performance ’09, a large-scale study was launched based on a very reliable number of Google servers.[ 6] small studies or surviving laboratory studies, with an error of 25,000 (2.5 × 10 to 11 /bit h) to 70,000 (7.0 × 10 ≈ 11 or maybe be, error/bit h, 1 bit error/gigabyte RAM per 1.8 pips hours) per billion d device hours one megabit. More than 8% of DIMMs failed each year.

  • The consequences of a storage failure vary by system. On non-ECC systems, an error can result in data file failure or corruption; Memory errors are one of the most common causes of printer hardware failures, especially on high performance websites.[6] Memory errors can lead to security issues Safety.A [6] Memory errors can only have consequences if they change only slightly, which does not lead to noticeable malfunctions and does not affect the data used in calculations and stored. A 2010 simulation study found that in the presence of a web browser, a small portion of the data associated with memory problems leads to corruption at best, although the impact of memory errors is greater than expected because many memory errors are discontinuous and contiguous in independent software errors. . .[8]

    Some tests show that isolation of the DRAM memory structure can be bypassed by inadvertently rewarding specially crafted access to neighboring cells. Thus, accessing data stored in DRAM makes updating memory wasteful and fun, as the higher cell density in modern memory updates the contents of adjacent rows not reclaimed by the original memory access. This effect is known as Row Retracted and was also present in some computer privilege escalation vulnerabilities.security.
