I just ordered a new server for work with 192gb of ram. like I can't even fathom having a use case here where we'd come even close to needing that much but gently caress it, I ain't footing the bill probably set up some as a ramdisk and put tempdb on there for sick nasty speed

bit flips in RAM happen all of the time now that we make it at such a high density. usually the bit is somewhere where you don't notice it, like the data for an image or video. but sometimes it hits your OS and you get a blue screen or other major fault. many of your application crashes are due to it, and it is slowly but constantly corrupting data you write to your hard drive. then you open up that word document and find that something is messed up, but you just blame word for being a piece of poo poo. for normal users the frequency of observed errors is low enough and random enough that they will not feel any benefit from ECC RAM. but you probably don't want that on your servers, or on the machine that builds/generates the final version of the product you're about to release. you also want a CPU that has ECC in the cache.

yeah that started with either vista or 7. basically it will load your most-used files into unused RAM. if you have an active program that needs that RAM, the cached data is immediately flushed in favor of whatever you're actually doing. it's good

Sagebrush posted:What's the actual use case for ecc RAM? Like, ram errors clearly must be either super uncommon or easily rectified, cause the average user doesn't ever see "poo poo is hosed up cause of RAM bit flips" There are some caveats, of course. It's their job to show that it's not Windows's fault that your computer sucks. More important for your question, however, they drastically underestimate the damage of DRAM errors. They only assume a crash happened due to a DRAM bit flip if the wrong bit happens in the Windows kernel's code pages (because they can know exactly what the memory *should* be). To quote, "...the only DRAM bit errors that cause system crashes are those that occur within the roughly 1.5% of memory that is occupied by kernel code page". Still, in that tiny amount of memory, your average shitbox machine has a 1/1700 chance of failing due to a bit flip in the kernel's code pages in an 8 month period (assuming its on for at least 30 days within those 8 months). After the first crash, it's much more likely to happen again, which is indicative of hard faults in the memory.

lol if you think your ram vendor spent the amount of time it takes to qualify your consumer ram is actually good.

this ram is $20 cheaper on newegg, so I bought that. there's no difference, the numbers are all the same

consumer hardware sucks and if you care at all about data integrity or system reliability then every single piece of memory in your system will be ECC from the ram to the cpu cache to the raid controller to the NIC

After the first crash, it's much more likely to happen again, which is indicative of hard faults in the memory. I've heard from an Intel chip engineer that the Windows 98 blue screens were basically all Intel's fault for not doing sufficient error checking at each stage of the datapath on their chips. I was shocked to learn (probably due to naivety) that even on-chip they don't guarantee that errors due to cross-talk aren't engineered out and instead they do error correction to fix those things. silence_kit fucked around with this message at 16:21 on Mar 28, 2016 |

It's astonishing that microchips work at all, considering the scale and complexity of the devices and that they're pumped out by the billions and sold for a few dollars Any deterministic process running billions of times per second with any level of reliability or repeatability is completely magical as far as I'm concerned
