Why is taxing non-ECC RAM instead of ECC RAM more of a problem in this regard than the thousands of other taxes? The government imposed a 12% GST on all computer gear just because they felt like it. Would making ECC RAM…
But no-one here has advocated banning anything. Please read before replying.
I respect the time of my readers by accurately presenting my claims. It seems that everyone other than you was able to understand "My experience of memory errors".
If it's none of your business why are you getting so involved in this discussion?
Good point. Some googling suggests that plastic may be better than metal as hydrogen absorbs high energy protons without generating secondary radiation.
The people designing RAM and motherboards and the people working at JEDEC will of course know more about these things than almost everyone who reads hacker news. But I'd still prefer not to just blindly trust that they…
How do YOU propose doing this when most computer "experts" have never used ECC RAM and when it's only available in high end specialist systems that aren't on sale in regular computer stores? I think my knowledge of the…
The original IBM PC/XT had parity RAM. In the early PC/XT and PC/AT clones you had banks of 9 DIP sockets for memory chips with the 9th being for parity. The DDR4 ECC RAM has 72 bits total and 64bits of data which means…
I'm planning some RAM purchases for the end of this year, I expect the crash to happen in a few months.
BTRFS has checksums on all metadata. It isn't designed to cope with bad RAM but has been shown to be somewhat resistant to it to the degree that BTRFS developers can recognise symptoms in problem reports. Whether a…
No-one ever proposed making non-ECC RAM illegal, that's a straw-man. Restricting risky items is standard practice for all governments. All the "use by" dates on food etc are from government regulation. The current…
I can only report what I have seen. Feel free to write your own blog post reporting what you have seen.
Yes a kernel taint is a really good idea!
For second hand gear RDIMMs are significantly cheaper than UDIMMs. As all RDIMMs have ECC that means generally ECC is cheaper for second hand systems. Aliexpress had $50 single socket motherboards for Xeon E5-26xx CPUs…
I have a HP Z640 that only has 3/4 DIMM slots working. Reseating the CPU didn't help and the same CPU works perfectly in another Z640. I never found out the cause. It was sold as "unknown condition for parts" so $50 for…
A very large portion of people who go from working on consumer grade systems to getting enterprise grade stuff for their home lab make a mistake like that, I did some similar things, my biggest mistake was spending $300…
https://www.theregister.com/on-prem/2021/06/04/fyi-todays-co... Google and Facebook report a few unreliable CPU cores out of thousands of systems. Meaning maybe a 1/10,000 rate of repeatable CPU errors.…
People outside the US have a significant lack of Internet functionality when there are problems with submarine cables, but it hardly ever fails. Apart from when certain countries sabotage things. If you only need 100M…
Companies making DRAM have no incentive to make the best products theoretically possible, they just want them good enough to not get many returns and avoid the risk of a class action lawsuit if a significant pattern of…
Does this imply that the all plastic gamer PCs (that are more designed to be art projects than serious computers) are bad and that everyone should be using systems with solid steel cases to block radiation?
The majority of storage errors I've seen since using BTRFS and ZFS everywhere have shown up only as the storage returning corrupt data and claiming it to be good. I've seen drives and SSDs return dozens of errors per…
Systems with "consumer amounts of RAM" are often run with what you might call "consumer amounts of sysadmin knowledge" and not notice the errors. One time I took a working workstation from my home to my parents' home to…
I know a guy who uses old rack mount servers as workstations and he gets that. I guess it's a good option if you like wearing hearing protection at your desk as he does.
That sort of thing seems like a good idea. There are X programs (and presumably Wayland programs) that do similar things (like web browsers stopping things when switching to a different tab or minimising the window).…
By default qtwayland5 is not installed, should this be considered a bug?
