Any chip count not divisible by three or five indicates a nonparity memory module Using ECC decreases your computer's performance by about 2 percent Current technology DRAM is very stable, and memory errors are rare, so unless you have a need for ECC, you are better served with nonparity (nonECC) memory The other side claimed that ECC memory was slower than nonECC so it wasn't the right choice for a highend workstation where performance was a priority Much of the ECC versus NonECC argument Finally, ECC RAM is slightly slower than nonECC RAM Many memory manufacturers say that ECC RAM will be roughly 2% slower than standard RAM due to the additional time it takes for the system to check for any memory errors To verify this, we examined multiple benchmarks that we run on each system we produce

In that same 14 study cited above, Puget found that ECC RAM was 025 percent slower than nonECC RAM, with Registered ECC RAM being 044 percent slower (however, they determined the performance CPUs, Motherboards, and Memory ;If you are unsure whether you have ECC or nonparity, count the number of small, black, IC chips mounted on one of your existing sticks of memory If the number of chips on one side is even, as in 4 or 8, you have nonECC If the number of chips on one side is NOT even, as in 9, you have ECC
The majority of computers out there are running without ECC memory and have been for a long time ECC memory is slower, and much more expensive The day may come when the bitbleed from nonECC memory catches up with the Earth, but none of us will ever see it There are much weaker links in your computer than nonECC memory 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 Second is ECC versus NonECC, ECC is just better, there is many reasons for using ECC over NonECC I found this quote on Wikipedia " Errorcorrecting code memory (ECC memory) is a type of computer data storage that can detect and correct the more common kinds of internal data corruption
Physically, ECC memory differs from nonECC memory (like what consumer laptop / desktop RAM uses) in that it has 9 memory chips instead of 8 (memory chips are used to store data that is sent toI have googled it, and it appears that it is better to get nonECC memory, because Memory is already fairly stable NonECC memory performs better than ECC memory NonECC memory is ECC allows you to truck along happily immune to single bit errors, and in this respect is clearly superior to nonECC RAM However, in order to understand ECC's value requires understanding memory error frequency and root causes

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 MemoryNonECC, or nonparity, memory is fine for most systems not running a server ECC SDRAM Guide ECC or Nonparity?ECC vs NonECC 5 VIKING TECHNOLOGY – AN0031 ECC vs NonECC Whitepaper Rev A Figure2 Example of NonECC Memory Standard RAM uses banks of eight memory chips in which data is stored and provided to the CPU on demand ECC memory or ECC

ECC DIMMs typically have nine memory chips on each side, one more than usually found on nonECC DIMMs (some modules may have 5 or 18) Error correction code memory ( ECC memory) is a type of computer data storage that uses an error correction code (ECC) to detect and correct nbit data corruption which occurs in memory The cheapest and most readily available Ram type today is DDR3 SDRAM It is "safe" to use over ECC for personal workstation needs unlike the new LGA 11 generation that the system you are suggesting uses and supports all types of DDR3, ECC and nonECC, older Xeons that were under a "blanket" rule of thumb configuration that needed to support mainly servers, opted for ECC only memoryErrorcorrecting memory is a popular choice when you simply can't tolerate any kind of error or data loss How does it work?Freshbooks message Head over to

While marginally more expensive than nonECC RAM, the added protection it provides is critical as applications become more dependent on large amounts of data Likelihood of a Memory Error On any server with financial information or critical personal information, especially medical, any data loss or transcription error is unacceptable Unbuffered ECC versus Registered ECC Memory Adding to the ECC concept, there are two concepts at play, unbuffered and registered ECC memory modules The basic difference is that memory commands in unbuffered memory configurations go directly from the controller to the memory module, while in registered memory configurations the commands are sent first to the ECC RAM vs nonECC RAM Compared to nonECC memory, ECC memory has obvious advantages Because of the builtin errorcorrecting capacities, systems with ECC RAM experience far lower failure rates than nonECC RAM setups In practice, this means less data corruption, fewer crashes and more uptime – key objectives for applications that process

No doubt that ECC RAM is highly recommanded (required will say Cyberjock as it is red writted in the Sun whitepaper), and don't want to start again a long debate ECC vs NONECC as there is no discussion to be had from a technical point of view, and as there is enough ink on the forum about that While both do all the things a memory should do, an ECC memory offers more than your regular reading and writing of data An ECC memory will automatically detect errors that come from your memory and will automatically correct them A nonECC memory won't do it but it does perform a bit faster, and will also be slightly cheaperAn ECC (Error Correction Code) RAM has extra memory bits in it to allow automatic

According to this link, nonECC memory has around a 0% failure rate, but ECC memory is around 2% slower than nonECC memory It depends on how much you are willing to pay for that extra bit of stability Not all motherboards are compatible with both ECC and non ECC so be careful Most of your single processor non workstation boards will not use ECC ram and most of your dual processor worstation boards will In most cases it is rare for a board to accept both ecc and non ecc ram but the boards do exist in "MY" opinion if the board will accept 71 #2 for the most part server boards use registered for large dimm sizes servers always should run ecc most consumer boards do not like ecc (and/or registered) mixing is mostly not allowed either an hp workstation can rock ecc or nonecc (xw4400 example) ddr2667 the same motherboard in an hp low end server has a bios
