Forget about desktop processors and buy yourself a double-socket LGA2011v3 board and some engineering-sample Xeons. Then you can address that kind of memory and run ECC. The clocks are a little lower than the retail Xeons, and you do need to pay attention to compatible boards/BIOS versions, but you can get a big Xeon E5 for like $200-300.

> Forget about desktop processors and buy yourself a double-socket LGA2011v3 board and some engineering-sample Xeons. Then you can address that kind of memory and run ECC. If you follow this very thread, you'll notice that another user already complained that "you need to pony up for a Xeon workstation if you need more than 64 GB."

"Ponying up" here means, in context, Xeon processors that are several thousand dollars each. In contrast, the grandparent was wishing that he could use a Zen that cost several hundred dollars instead.

I was pointing out that there were other processors already on the market that met his requirements: Xeon engineering samples, which most people don't think about when they are talking about the costs of high-end Xeon workstations.

(This is partially because they are not "finished" products like retail chips. Clocks are lower, and you need to use motherboards/BIOSs from a specific compatibility list, and they are not something you can source from Intel. Thus, they slip many people's minds because they aren't something you would consider for an actual server deployment - but they are perfect for a workstation with specialty needs that needs to hit a tight budget)

So yes, I did actually read the thread. You just didn't grasp enough of the context to make a sensible response and figured it was the perfect time for a superslam "did you even read bro?" gotcha response.

Typically this sort of response is not welcome on HN. If you don't have something substantiate to post, please don't post at all.

If you can afford a $30,000 medium format camera, you can afford the Xeon workstation it usually needs. The kind of person that work with those systems would pay $6,000 for an umbrella that doesn't even have any electronics in it: https://www.adorama.com/bcb3355203.html?gclid=CLKvmd2erNICFY... Absolutely no one that owns one of these professional cameras uses them with non-Xeon CPUs. Really the only use for greater t…

While still true it might not be for long: "advanced amateur" small formal SLRs with 36mpix @42bpp now start below $2000 and 24mpix @36bpp in the lower part of $500-1000 bracket. https://www.adorama.com/ipxk1.html https://www.adorama.com/inkd810.html https://www.adorama.com/inkd7100.html Which brings a slightly unrelated note: people seem to be blissfully unaware that you need less than 9mpix for a 12x9" 300 dpi prin…

I used to shoot 33megapixel medium format cameras 10 years ago, on 8GB machines with 1GB GPUs just fine, doing multilayer photoshop on 48-bits-per-pixel TIFFs.

64Gb is completely unnecessary for photography. Photographers don't even go over 16GB.

I'm maybe the only amd fan who is going to miss my power/$ of my 8350 for 150$ (or was it even cheaper?...)

I can say I don't miss the $/power from my electric bill when I shut down my 8350 home server/nas box.

That 65w does look pretty impressive!

Quantum chemistry. There are a number of high accuracy wavefunction based methods that are compute-tractable on desktop machines but very demanding of storage. Even when there's a disk based alternative to RAM storage it's a lot slower when you can't just allocate huge arrays in memory. I could easily use 256 GB, maybe 512, on a machine with 8 physical cores. You can get commercial software that is a bit better tuned…

Thank you for the suggestion. I am surprised how cheap these can be. It has been years since I assembled a system from parts so I had been looking at complete workstations from vendors, but for that much cost saving it is worth considering parts-assembly.

Undoubtedly. Such obvious delusions are commonplace and don't necessarily correlate to one's scientific literacy or electrical engineering skills. Such audible differences constitute a testable claim . So far, the number of claims that have withstood reasonable test conditions is zero.

Do you subscribe to the AES journal? This explains why 16-bits isn't enough: http://www.aes.org/tmpFiles/elib/20170226/18046.pdf

Nice 404.

Nobody is arguing that 16 bits is enough during the recording and mixing process. If they are claiming that 16 bits is insufficient for consumer distributed music, they need to go back to remedial science class.

> Dither was developed precisely because naively interpolated or truncated 16-bit audio is audibly inferior to a 24-bit source. Dither was developed because it's technically better. Audibly inferior though? Perhaps, with utterly exceptional source material (e.g. test tones) and when the output gain is high enough for peaks levels to be uncomfortably loud. In reality, many recording studios have a higher ambient noise…

A high noise floor is not even close to being the same as dither, never mind noise shaping. Have you actually heard the difference between simple dither, noise-shaped dither, and non-dithered 16-bit audio? A test tone is the worst possible way to hear what they do. 24-bit audio is used because you want as clean a source as possible. This also applies to mastering for output at the other end. With the exception of CD…

> A high noise floor is not even close to being the same as dither, never mind noise shaping.

Dither is noise. Well chosen noise, very quiet noise, but noise nonetheless. Whether the signal is noisy for one reason or another, the consequences at the point of decimation/quantization are the same. Either way the least significant bits are filled with stochastic values and the desired signal isn't plagued with quantization noise artifacts.

> Have you actually heard the difference between simple dither, noise-shaped dither, and non-dithered 16-bit audio? A test tone is the worst possible way to hear what they do.

...is the sort of thing someone who hasn't done a blinded listening test would say. Stop assuming the commercially successful "experts" are also technical experts, because few are. I doubt more than a tiny fraction could describe what a least significant digit is.

(Cutting vinyl, a hilariously lossy process that requires compression and EQ to avoid the needle jumping the groove, doesn't need a 24 bit master. Barely needs a 14 bit master. But since an extra hundred megabytes of really accurate noise floor doesn't make anything worse, they do it anyway.)

I think this is a bit too simplistic for HPC. Yes, you can go really low cost if all you care is theoretical performance / $. In practice, the cost efficiency of the system should be seen as 1 / (time to solution for typical applications) / (cost of ownership per year). Even 20% higher memory bandwidth or computational performance per socket matters for the time to solution, since a higher number of nodes is uncertai…

Yes that's a fact, and if you're trying to evaluate a solution based on performance/$ then the comparison is made with regards to this factor, and not others. > In practice, the cost efficiency of the system should be seen as 1 / (time to solution for typical applications) / (cost of ownership per year).

Would you care to tell how to get hold of such a system, which sites to visit? Thanks!

Just a reminder that wccftech.com is notoriously pro-AMD. I would caution against taking their word as proof. I'm not an AMD hater (actually own AMD stock), just cautious.

>actually own AMD stock Any insight for that? Why do you think AMD is good investment (or speculation).

As another investor, the stock has already gone up 650%. You should probably look at another company to buy. Never buy during the hype.

Yes, customer Ryzen CPUs support ECC.

No, they don't. > We did ask about a potential single socket Ryzen/ Zen part with ECC memory support and were told that AMD was not announcing such a product at this time alongside the Ryzen/ Zen launch. https://www.servethehome.com/amd-ryzen-7-parts-available-for...

Ryzen does support ECC. Confirmed by the CEO of AMD in the Reddit AMA.
