Ecc Vs Non Ecc
I am about to upgrade my DELL XPS 8900 and add 64GB memory to it, I have found that the montherboard of DELL XPS 8900 does support that kind of capacity.However I have a hard time picking up the right RAM. DDR4 is supposed to be better than DDR3, but other factors seem to weigh in.Like some examples shown below, DDR3 is not necessarily cheaper, and appear ECC is a plus factor too: #2, Kinston's DDR3 is more expensive than #1, DDR4 from Curcial, and the #3 is the most expensive, can ECC alone explain the price gap to #1? And do these difference translate into a perceptible performance difference?From Crucial official site:. Crucial 64GB Kit (4 x 16GB): DDR4 PC4-21300. CL=19. Dual Ranked. x8 based.
Non-ECC MEMORY Document #AN0031 – ECC vs. Non-ECC Memory Whitepaper Rev A Purpose of this Document This application note was prepared to help OEM system designers evaluate the performance of Viking solid state. Nov 19, 2015 To ECC or Not To ECC. On one of my visits to the Computer History Museum – and by the way this is an absolute must-visit place if you are ever in the San Francisco bay area. Most non-ECC memory cannot detect errors although some non-ECC memory with parity support allows detection but not correction.

How To Identify Ecc Vs Non Ecc Memory
The best RAM depends on your needs/requirements.DDR 3 is probably not what you want. It's generally slower and significantly more power hungry then DDR4 (40percent is bandied about - probably not too big a deal on a deskop though)ECC is more expensive because it's a lot more reliable and requires extra chips for reliability and calculation. If you are using it as a server this is probably a good idea - for a gaming rig or workstation it's probably unnecessary. If you are running a ZFS filesystem (if you don't know what it is, you aren't), you really need ECC. ( Unfortunately regular memory can very, very occasionally have a bit flipped due to cosmic radiation (or going faulty) - the question is what is the value of protecting against that - good quality non-ecc memory is still subject to bit flips.Most desktops would use the cheaper DDR4 memory, most servers the ECC memory, and yes, a good part of the price difference is because it's ECC.
ECC simply has an additional chip on the stick that monitors/fixes/prevents memory bit errors. Usually only used on servers and high availability equipment; or in l1, l2, and sometimes l3 caches.The majority of motherboards will only support one or another, workstation and server boards for example need ECC usually and almost all consumer grade boards only use non ECC. Now if you really care to find everything out about ram that you can, figure out what an FB-DIMM has in common/contrast to simple ECC or non-ECCAll my servers use FB-DIMMS, expensive but they are the most reliable type of memory these days. Plus the whole serial thing instead of parallel. Seems like everything is going serial these days.Edit: RDRAM was an exception, it's ECC as well, I believe it all is but I can't say for sure. I have 3 older PIII's with it and they are all ECC. Faster with my sql and mysql servers than PIII's with SDRAM, by a large margin.
