Would you use ECC RAM in a workstation? - Server Fault
WEBMay 7, 2009 · ECC RAM is more expensive than non-ECC, is much more sensitive to clock speeds, and can incur a small (1-2%) performance hit. If it helps, an analogy that works is RAM to RAID controllers. On your PC, that hardware-assisted software RAID built into your chipset is great protection against single disk failures.
memory - What is ECC ram and why is it better? - Server Fault
WEBMay 7, 2009 · 28. ECC RAM can recover from small errors in bits, by utilizing parity bits. Since servers are a shared resource where up-time and reliability are important, ECC RAM is generally used with only a modest difference in price. ECC RAM is also used in CAD/CAM workstations were small bit errors could cause calculation mistakes which become more ...
How to check if RAM is running in ECC mode? - Server Fault
WEBOct 21, 2016 · 1. While your output may vary, to check for EDAC information in dmesg you can run dmesg | grep EDAC (you may need to run this with root privileges). For example, on a Ryzen-based system with ECC memory installed and enabled in the BIOS (if applicable), you may see a line which looks like amd64: Node 0: DRAM ECC enabled. – Joe.
Difference between regular RAM and ECC RAM [duplicate]
WEBSingle-bit memory errors can happen even if the RAM isn't faulty, and can happen practically spontaneously ("Electrical or magnetic interference inside a computer system can cause a single bit of dynamic random-access memory (DRAM) to spontaneously flip to the opposite state."). ECC for catching those one-off system errors, not to make it keep ...

WEBOct 21, 2015 · Accordingly, 2 ranks of DDR module has to hold 16 RAM chips (18 with ECC), 4 ranks of DDR module has to hold 32 RAM chips (36 with ECC). There are also x4 and x16 DDR modules. Their DDR modules has to hold 16 and 4 physical RAM chips soldered per 1 rank respectively (to become a 64 bit wide memory).
memory - What happened to ECC RAM? - Super User
WEBMar 22, 2021 · This January 2021 article in ExtremeTech provides a fairly solid summary of what happened: “ Linus Tovalds Blames Intel for Killing ECC RAM in Consumer Systems ”: “There was a time when you could buy ECC support on mainstream chipsets, but Intel phased out that capability on non-Xeon platforms a number of years ago.
memory - ECC registered vs ECC unbuffered - Super User
WEBUnbuffered/unregistered ECC will actually be faster. Buffered/registered ECC will be at least one register action slower but you can add more DIMMs to a memory channel. (And more memory CAN make your system faster, even if latency increases). So rather then a hard "Yes/no" the proper answer is "it depends". – Hennes.
Is there a certain or measurable advantage to using ECC RAM in a ...
WEBI've used ECC ram in servers for a few years now. ECC really shines when you are using your machine heavily, as in "it's on more than 12-16 hours a day". Little whitebox servers I've built without ECC have, sooner or later, developed "issues" that required a reboot, but the ECC machines have never had these.
