Workstation Check

[shubhamcivilengg7]

I am building a workstation for my civil engineering PhD research. I will be running heavy finite element analysis (specifically LS-DYNA). These numerical simulations will put the CPU under 100% sustained load for anywhere from 12 to 24+ hours at a time.

The Proposed Build (Quote from local vendor):

CPU: Intel Core Ultra 9 285K (24 Cores)  

Cooler: MSI MAG CORELIQUID A15 360mm AIO

Motherboard: MSI PRO Z890-A WIFI

RAM: 192GB (4x48GB) ACER DDR5 6000MHz CL28

GPU: Zotac RTX 5070 Ti 16GB

Storage: 1TB WD Black Gen4 NVMe + 2TB WD Blue HDD

Case: Cooler Master MasterBox K501L RGB

PSU: MSI MAG A850GL 850W Gold

My Specific Concerns:

 Given that the Ultra 9 285K pulls up to 250W under sustained load, will the MSI A15 360mm cooler inside the Cooler Master K501L case be enough to prevent thermal throttling during a 24-hour solve? I know the K501L has a somewhat restrictive front panel compared to modern mesh cases. Should I ask the vendor to change the case?

RAM Stability: I need massive memory capacity for the mesh sizes I am working with. However, I’ve read that running four sticks of DDR5 to hit 192GB at 6000MHz puts a massive strain on the memory controller. Will this Z890 board actually run 4x48GB stably at 6000MHz, or will I be forced to downclock it to 4800MHz/5200MHz to avoid crashes during my simulations?

General Bottlenecks: Is there anything else in this configuration that stands out as a bottleneck for long-duration FEA rendering?

watch out with the intel CPUs, i have some intel (laptop) workstations at work and they get stuttery at random for some reasons, those E and P cores are not working that well in my experience, you will probably have a better experience with AMD threadrippers (and possibly save some bucks too depending on your core count/performance per single core needs). i might be biased but intel CPUs while on paper looks great i have noticed they are not that good for some reasons, also i have experience with in laptops which are probably NOT the same in terms of experience but i thought it's worth to share anyway.

 

about the case for sure it will look cool but i'm not that sure that it might have a good ventilation, looks like it have less then half of the front panel with a mesh and the rest is solid. i think a better choice would be the corsair airflow cases, i own the 4000D and it both looks nice imo and it has a fully mesh front panel, if you can choose the case i would go for the corsair one for a better airflow, or at least check what cases you can choose between.

 

about the stability of the RAM it depends a lot on the silicon lottery, however if the RAM is sold for a set speed IT WILL ru nat that speed since it's cherry picked for those performances, this being said, you could underclock them a tiny bit and you will probably not feel any different in speed if you seek more stability, but running the RAM at it's rated speed is always the right choice. Also, the manufacturer's compatibility page has many informations about what speeds you can reach based on the RAM configurations, just check there and you'll have the correct answers for your needs

 

besides this i don't see anything wrong/weird, the case to me is not that good and kinda airflow restrictive, the intel CPU is toasty as fudge but if it's the only options you have and you can't go with AMD it's still fine (to be fair, in your specific use case EVERYTHING will be toasty as hell probably), my experience with intel CPUs again is based on laptops CPUs and i don't like intel that much personally which i might be kinda biased.

The QVL for the motherboard has verified a few 48x4 sets, but none that are 6000+MT

I don't know much about the technicalities about you use case, but you should also consider getting something that supports ECC memory

The motherboard memory QVL lists several kits of 4x64GB 5600. While not a guarantee, being on a memory QVL offers some assurance of stable operation at listed specs. I wouldn't obsess over memory speeds.

Consider an air dual tower cooler instead. There are several models that should comfortably handle 250W sustained loads.

Invest a bit more in the case and consider something with a full mesh front and great airflow. Lighting should not be a consideration.

Nice choice.

This might not make a difference since you are buying it through a vendor, but keep in mind that Intel just announced Arrow Lake refresh:

 

https://www.techpowerup.com/347251/intel-launches-arrow-lake-refresh-core-ultra-5-250k-plus-and-core-ultra-7-270k-plus-new-binary-optimization-tool

 

In particular, the U7 270K Plus is basically a slightly cut-down 285K (same number of cores, just slightly lower clocks and no TVB) but is much, much cheaper.
