I am wondering what is the current stance on this years later? the-usefulness-of-ecc-if-we-cant-assess-its-working.83580/ ?

Was a few years now, so maybe I misremember if it was soldered or not… But I 100% remember reading through the post & seeing some madman with wires sticking out of his dimms to introduce errors physically. So I’m very certain it was you :stuck_out_tongue: Thanks again for the work as I’m sure I’m n…

Anyone ever wonder why enterprise/datacentre grade equipment frequently features these? :wink: [eng_pl_WS-X6704-10GE-Modul-Cisco-Catalyst-6500-6800-6944_2]

I don’t have any data to offer, just my anecdotes. I’ve been building PC’s for over 2 decades since I was 16. 15 years ago, I started building “server” that would run 24/7 using spare parts from all my gaming rigs that I’ve accumulated whenever I upgrade. There is always some issue and unexplained …

[image] Constantin: But bit flips in RAM can potentially alter a file before it hits the disk. If the alteration happens before the checksum is calculated, your NAS might be writing a corrupt file to the NAS for whom however the checksum will match. Every replication of said bad file then perp…

Your summary neglects to mention that data is also stored in the ARC for varying amounts of time. The ARC resides in RAM. Faulty or compromised RAM can absolutely change data passing through it in ways that checksumming on data at rest does not catch.

[image] truenas-fan: You DO NOT need it! How would you know when you don’t know what the OP is using the hardware for? [image] truenas-fan: First, properly made cases are FARADAY CAGES, correct!? No? I guess it depends on how you (specifically) define “properly made cases”. Depending …

First off the bat. I want ECC and I (religiously) believe I need it. I am the OP. I had difficulties getting back access to my original account thus I made a new one also stating my feelings years later. I was the one that actually made it possible to assess if ECC is working by means of physical…

I want ECC, even on my desktop, there is absolutely no reason it shouldn’t be standard aside from artificial market segmentation nonsense. but I do not want to (and have refused to when it’s a choice) pay the ridiculous premiums that ECC UDIMMs cost. Let me be perfectly clear, ECC UDIMMs just have …

the problem is that not only the memory needs ecc functionality. the motherboard and the cpu all need as well. so even if the memory was only 11% more expensive then there is still the extra costs ( inflated or not) of the rest of the components to deal with. For my data store. I refuse to use hard…

since i cant edit my post yet; I meant headware I have confirmed to be ECC functional. This leaves me with a bit of a headache. If I need to buy new hardware in a year or 15. then how to I confirm functionality by then? If all the current vendros seem to be cool with this cult. I hope risk-v by …
