@JourneymanGeek told me to ask for help here - I has been tasked to put up together a PC configuration that would run a discrete simulation software and I wonder if anyone would have any tips at what to look when building one - not specific components but just general advice if you had experience with similar stuff
I have been thinking about Xeons, as we tested soft on intel processors so far (what we had available at work), was thinking of AMD due to higher core count
@JourneymanGeek of course, sorry did not want to spam chat with links without even saying hi to everyone first, links here: superuser.com/questions/1452650/…
It is going to be work pc with high-ish budget, so it aint my wallet that is going to cry, basically idea is to first think of what cpu and mobo to use, then fit ram, and some speedy ssd
@internetofmine The most cost-effective solution is going to be Ryzen 3000 series, no question. But if this is a workstation where you need server-grade reliability and 20+ cores, I'd be inclined to suggest either EPYC or Xeon instead.
@djsmiley2k Literally cheapest mobo I could find. My dad fried his PC and tasked me with fixing it. It's got some bizarre weird bugs and I'm building a new one and his budget is quite tight.
His current build has a single RAM chip, probably 8 or less GB.
Also his current mobo claims the HDD has I/O errors despite every other PC reading it fine. Which is bizarrely weird.
Maybe the SATA controller is fried?
Hence me looking for a new mobo
Just looked, 4G currently.
A Gigabyte GA-B75M-D3H
Besides I/O issues it also randomly loses power when it should beep on POST.
So I could either try to troubleshoot random bizarre errors, or build a new PC.
As my personal time is quite short and I'm starting uni again (third time's the charm, huh?) in two weeks... I think it's the best approach.
What was your... How do you say it in UK English? ( I know in US English it's "majored in" but here we don't have majors / minors and I think neither the UK.)
@djsmiley2k I swapped the cables and power source so probably the controller. Weird is it does read albeit slowwwwly and with errors, like a real bad HDD.
Well, this is interesting... This "algorithmic" approach Microsoft claims it takes to charging Surface devices is showing as a bit of an oddity in the charge rates I'm seeing on this tablet: 1.0C below 50%, 0.7C between 50% and 80%, and 0.5C above 80%.
Clearly, despite technically being able to charge at a faster rate, Microsoft has decided to limit charge speed at high charge levels instead of relying on CC/CV alone in order to extend battery service life.
Semi-custom AMD processor solution for a high-performance system? Because I'm not 100% confident about AMD's mobile power efficiency at this point. This might make more sense for a Surface Studio-type machine...
According to various other related questions, I have gotten the following command

However I get the following when telneting:

@internetofmine Does it have to be a desktop tower/workstation, or is a rackmount okay?
You have a number of choices. Considering the nature of the application, the safest bet is going to be Intel Xeon Scalable. But this is the most expensive of the solutions available.
Xeon W is a workstation-oriented version of Intel's Xeon Scalable processors. It doesn't offer the same level of scalability, but is probably the most appropriate for your application.
Considering that we're talking about very expensive process simulation software (Lanner WITNESS Horizon), stuff that runs thousands of dollars a seat, your hardware should match.
I'm very, very hesitant to suggest Threadripper because of the oddities with its memory architecture. The Threadripper WX processors are extremely powerful with the right workloads, but it behaves like a 4P server with memory attached to only two of the four processors. On the bright side, it does accept ECC memory, unlike Intel's Core X series.
Not to mention that AMD has new processors on the horizon. If this can wait (and I suspect it can't), you may want to consider AMD's second-generation EPYC processors, codenamed Rome.
Looking at the chat log... it seems like you want multiple processor sockets. How many cores do you need? If the answer is 20 or more, you need to look at specialized workstation/server platforms, because consumer desktops will not be adequate.
If the answer is more than 64, your only real choice is a 4P Xeon Scalable server. You could be looking at six figures at this point.
If the answer is 18 or less, Xeon W is probably the best answer.
