Let's say you corrupted one bit in a blender asset 200 revisions ago and it was unnoticeable and still upgraded through five blender upgrades, but now on the sixth upgrade it fails with a corruption error and doesn't upgrade. Without knowing how to fix that error you've lost 200 revisions of work. You can go back and find which revision had the problem, go before that, and upgrade it to the latest blender, but all yo…

So don't upgrade it. Export it to an agnostic format and re-import it in the new version. Since it's failing to upgrade, it must be a metadata issue, not a data issue, so removing the Blender-specific bits will fix it. What a silly hypothetical. There's a myriad freak occurrences that could make you have to redo work that you don't worry about. Now, I'm not saying single-bit errors don't happen. They just typically d…

Doing a lossy export/reimport process probably isn't going to be viable on something like a big movie scene blender file with lots of constraints, scripted modifiers and stuff that doesn't automatically come through with an export to USD.

My point is that there are scenarios where corruption in the past puts you in a bind and can cause a lot of loss of work or expensive diagnostic and recovery process long after it first occurred, blender was just one example but it can be much worse with proprietary software binary formats where you don't have any chance of jumping into the debugger to figure out what's going wrong with an upgrade or export. And maybe the subscription version of it won't even let you go back to the old version.

> There's a myriad freak occurrences that could make you have to redo work that you don't worry about.

Yes other sources of corruption are more likely from things like software errors. It's not that you wouldn't worry about them if you had unlimited budget and could have people audit the code etc., but you do have a budget and ECC is much cheaper relative to that. That doesn't mean it always makes sense for everyone to pay more for ECC. But I can see why people working on gigantic CAD files for nuclear reactor design, etc. tend to have workstations with ECC.

Trouble with enterprise is that the people buying care about the technology, but not the cost, while the people that do care about cost don’t understand the technology. Some businesses (and governments) try and unify their purchasing, but this seems to make things worse, with the purchasing department both not understanding technology and being outwitted by vendors.

Enterprise IT is overpriced so you can negotiate a 50% discount. Unfortunately negotiating isn't worth it for something like a pair of DIMMs.

Enterprise IT is overpriced because it's mostly people spending other people's money... which usually has a lot of turbulence in its flow...

Not really what I would call an "asset", but fine.

>It's not that you wouldn't worry about them if you had unlimited budget and could have people audit the code etc.

Hell, I was thinking something way simpler, like your cat climbing on the case and throwing up through the top vents, or you tripping and dropping your ass on your desk and sending everything flying.

>But I can see why people working on gigantic CAD files for nuclear reactor design, etc. tend to have workstations with ECC.

Yeah, because those people aren't buying their own machines. If the credit card is yours and you're not doing something super critical, you're probably better served by a faster processor than by worrying against freak accidents.

>I made a machine with a Ryzen 9900X a while back and it had the issue that it would freeze when idling I also have this issue.

You could try using powerprofilesctl to change the mode from 'balanced' or 'power saver' to 'performance' since i think this may prevent the cpu from ever entering the throttled down low idle states that your freezing happens in. they are controlled with powerprofilesctl. You may also be able to add some flugs to grub config file. assuming you are using linux i guess.

I have set my timings manually in the bios, and disabled most advanced CPU features for stability.

If I enable virtualisation, the issue can be replicated within 15 minutes of boot.

But with basically half the CPU set to do nothing, and all features disabled its once a week max.

Which sucks because I basically live in WSL.

Data science where you need to keep ~50GB of data in RAM and do intensive things with it (e.g. loop over it repeatedly with numba). You can't get use out of more than 4 cores because memory bandwidth is the only limitation. The data is too big for AMD's cache to be a factor. Threadripper is built for this. But I am talking about the consumer options if you are on a budget. Intel has significantly more memory bandwidt…

This? https://old.reddit.com/r/LocalLLaMA/comments/1ak2f1v/ram_mem... I can't see how that supports your conclusion.

There's many red herrings in that table (namely: old DDR4 consumer platforms, server platforms, low bandwidth DDR5 sticks), but surfacing the two relevant numbers (DDR5-6400 consumer heads-up comparison):

> AMD 7900X - 68.9 GB/sec

> Intel 13900K - 93.4 GB/sec

That's 35% better.

This does not fill me with much hope. What am I even ought to buy at this point then, I wonder. I have a ~13 years old Intel CPU which lacks AVX2 (and I need it by now) and I thought of buying a new desktop (items separately, of course), but that is crazy to me that it freezes because of the CPU going idle. It was never an issue in my case. I guess I can only hope it is not going to be a problem once I completed buil…

It's either bad luck, bad power quality from the mains, or something in the air in that particular area. I know plenty of people running AM5 builds, have done so myself for the last couple of years, and there were no problems with any of them apart from the usual amdgpu bugs in latest kernels (which are "normal" since I'm running mainline kernels — it's easy to solve by just sticking to lts, and it has seemingly impr…

I have a really specific Xorg config with my own kernel boot line in GRUB for amdgpu, it seems to work for me. I have not experienced any bugs with amdgpu so far. The GPU and HDD / SSD would stay anyway, I would only have to get everything else.

> I thought of AMD Ryzen 7 5700 Definetly not that one if you plan to pair with a dedicated GPU! The 5700X has twice the L3 cache. All Ryzen 5000 with a GPU have only 16MB, 5700 has the GPU deactivated.

I have a lower-end Radeon GPU (Navi 24 [Radeon RX 6400]). Which CPU would you suggest with it? I only ever want to use the GPU though, not the CPU's integrated one. I kind of want to get a motherboard that is compatible with the latest AM socket, which is AM5, right? So if I want a CPU with AM5, what would you suggest for the CPU?

But see, this is why it is so difficult. I would have never guessed. I would have to research this A LOT, which I am fine with, but you know.

That is your CPU temperature, not ambient (room) temperature.

Oh, I misread. My bad!

Just to add, I moved into a house where it is almost always between 27-30 C. It is AWFULLY hot for me. :( Sadly it will not go below this during winter either because they will start up the heating and it cannot be turned off.

52 minutes to post a screenshot? Guess someone doesn't want to be embarrassed.

Someone flag this comment for insult. I was at work, was taking a break, I wasn't on my personal computer.

I posted my screenshot yesterday but it's not visible. I don't care anymore.

I am treated so unfairly, it's unbelieavable. People with insults get away without punishment, but my innocent screenshot is invisible.
