r/threadripper

UPDATE: Resolved - thanks u/nauxiv!

I'm trying to get this new server build to boot and I'm not having any luck. I've tried all the usual things (see below) and now I'm wondering if I have a hardware incompatibility that I missing.

Specs:

• Motherboard: ASRock WRX90 WS EVO
• CPU: AMD Ryzen Threadripper 9960X
• RAM: G.Skill Zeta R5 DDR5 RDIMM ECC
  • F5-6400R3239G16GE8-ZR5K
  • 8-DIMM kit
• GPU: EVGA RTX 3090
• PSU: SilverStone HELA 2500Rz
• BMC firmware: 1.04.00
• BIOS: updated to latest available

Symptoms:

• System does not POST
• No video from RTX 3090
• No video from onboard/BMC KVM
• Dr. Debug cycles through codes, including 15 and d6, then resets to 00
• Appears to be boot looping
• With no RAM installed, Dr. Debug sits at 00

Things I've tried:

• Started with full RAM kit, then reduced to 1 DIMM in A0
• Tried more than one DIMM
• Removed RTX 3090
• Removed storage / minimal config
• Confirmed both EPS CPU power cables are connected
• Cleared CMOS with button and jumper
• Updated BIOS
• Reseated CPU
• Checked BMC sensors

BMC observations:

• CPU temp and voltage rails are present
• PROCHOT_CPU shows asserted
• BMC memory inventory shows stale/weird DIMM data that does not match current physical config

Help?

Hey everyone,

I'm considering moving from a high-end desktop platform to a Threadripper workstation and would really appreciate some advice from people who have experience with HEDT systems.

The goal of this build is to reduce compilation times, improve multitasking performance, and comfortably run several engineering workloads simultaneously.

Typical workloads include:
• Large Vivado synthesis and place-and-route projects
• FPGA development
• ASIC simulation and synthesis
• Multiple simulation tools running simultaneously
• Large FEA models
• Digital twin environments
• GPU training with CUDA
• Several virtual machines and Docker containers
• Software development and automation

The tentative configuration uses:
• AMD Threadripper (TRX50 platform)
• RTX 5080
• 128 GB DDR5 ECC memory
• Multiple NVMe SSDs
• High-capacity workstation PSU

I'm mainly looking for feedback on:
• Whether Threadripper provides a significant productivity improvement over Ryzen 9 for these workloads
• Whether TRX50 is the right platform or if there are better alternatives
• RAM recommendations (ECC vs non-ECC)
• Motherboard recommendations (ASUS Pro WS, Gigabyte, ASRock, etc.)
• Cooling recommendations
• Any limitations or issues you've experienced with Threadripper systems

If you've built or worked on similar engineering workstations, I'd love to hear about your experience and whether you think this platform is worth the additional investment.

... also 2 8tb Samsung Pro 9100 Gen 5 NVMe's. Why? Life and career changes, and moving to a 90% of the time gaming build. Almost 40 years in IT in one form or another, since high school in the mid-80's, so now it's time to just chill and game little.

Just for giggles I sent a message to ServerMonkey to see if they were interested, but (hopefully it's ok to post this topic in here) was curious what you guys would ask for these 9 month old parts:

AMD Ryzen Threadripper Pro 9985WX
Asus Pro WS WRX90E-Sage SE
Kingston Fury Renegade Pro Expo 256GB (x8 32gb sticks) 6400MT/s DDR5 ECC CL32
(x2) Samsung SSD 9100 PRO 8TB, 5th Gen NVMe's
(...shoot, I forgot to mention I'd throw in the Silverstone cooler/fans... ugh..)

I'm keeping my case, fans, Astral RTX 5090 and MSI MEG 1600w PSU and 2 of the same Gen 5, 8tb NVMe's, and going to grab a Godlike X870E Max board, Ryzen 9 9950X3D2 Dual, with x2 DDR5-6000 48gb CL26 sticks of ram for them. Case will be overkill, but I sure as hell ain't shipping this honkin' thing. Oh, guess I'll need an AIO .. dang... memory is going I guess.

What do you think a fair offer would be for these parts? I have the OEM boxes for the Proc and board, and would use them (probably leave the proc socketed). I asked ChatGPT and it thought $7k was a very solid offer to jump on, but I felt that might be low. Anyone with some experience selling Threadripper boards/processors and can offer some advice? Thanks!!

From what I’ve seen the lower a cpu is in its generation (5945WX) while having a lower core count, have much higher single core speeds.

My goal is to build a Homelab and to create a few (2-5) Minecraft servers running some heavy mods.

The issue I’m having is that I’d like to be doing that in addition to an LLM and a NAS/jellyfin. It’s a lot and I can’t fit enough hardware on a am4/5 cpu to make it work on a single node machine.

So I’m forced to go workstation or server route, the issue is how expensive these buggers are. So I’m thinking I can take advantage by getting not only a lower price but also a higher single core speed (despite less cores) I was thinking the 5955wx or the 5965wx because anything under 16 cores is silly if I’m paying for a threadripper,

Am I thinking about this wrong? Can I just over lock a 5995wx across all cores if I cool it properly?

I had it happen a month or two ago, and again today.

Symptom is my fans go to 100% even though CPU and GPU temps are mild (say machine at idle).

I have to do ipmitool mc reset cold and things come back to normal after a couple minutes when the BMC has restarted. My understanding is it could be due to a sensor not being captured by the BMC anymore, triggering a panic 100%.

Anybody encountered similar issues? How did you solve it?

Hey everyone, putting together a high-end workstation build and wanted to get some eyes on it before pulling the trigger.

**Use case:**

Primarily local LLM inference (targeting 70B parameter models), running open-source GitHub projects that interact with those LLMs (think local AI assistants, RAG pipelines, agent frameworks), and some virtualization on the side.

**The build:**

| Component | Pick |

|---|---|

| CPU | AMD Threadripper PRO 9975WX |

| Motherboard | ASRock WRX90 WS EVO SATA 6Gb/s DDR5 |

| RAM | Kingston FURY Renegade Pro 128 GB (8×16 GB) DDR5-6400 ECC RDIMM |

| GPU | ASUS ROG Astral RTX 5090 32GB GDDR7 OC Edition |

| Storage (OS) | 2 TB Crucial T710 PCIe Gen5 NVMe |

| Storage (Models) | 4 TB WD Black SN850X PCIe Gen4 NVMe |

| Cooler | Noctua NH-U14S TR5-SP6 |

| PSU | Seasonic Prime TX-1600 |

| Case | Fractal Design Define 7 XL |

| Keyboard | Logitech Ergo K860 |

| Mouse | Logitech MX Anywhere 3S |

| OS | Windows 11 Pro |

A few things I'm intentionally planning for: the RAM is 8×16 GB to keep all 8 memory channels active from day one, with a straight swap to 8×32 GB when I need to go to 256 GB.

Anyone see any compatibility issues I'm missing? Also curious if this setup makes sense for the use case or if there's something I should swap out. Thanks!

This isn't exactly the right sub for this, but I wanted to share somewhere since there's almost no information about this chip online - only an old wccftech listing that incorrectly lists the TDP as 280W, and some eBay listings that do the same thing.

The 7V73X is an Azure custom bin, only available secondhand. I bought mine from a Chinese seller on eBay. AFAICT it's identical in all respects to a 7773X, except that 7773X has 280W cTDP max, but 7V73X is hard limited to 240W cTDP. I verified using AMD HSMP + E-SMI tool. Mine's installed in an Asrock ROMED8-2T and the only other issue I had was getting the mounting pressure dialed in correctly (manifests as missing DIMM errors otherwise).

Nonetheless I still recomend it if you're looking for a V-Cache build, or trying to save money by going with a DDR4 build. Secondhand versions can be found significantly discounted from the 7773X equivalent.

I have an M3 Max MacBook Pro, and I bought the Threadripper 7980X with 64 cores because I thought it'd be able to run parallel code faster than the laptop which only has 16 cores. However, currently the MacBook is outperforming the Threadripper on both single-core and parallel performance. Now, I currently only have 32GB of RAM for my Threadripper (whereas I have 128GB RAM on my MacBook) so that may be a bottleneck. But before I fork out £2k ($2.8k) on more RAM, I wanted to sense check that this will actually outperform the MacBook? Or, should I sell the Threadripper and get the M5 Max instead?

I'm basically generating features with polars and running LightGBM ML models in parallel if anyone is curious about what I'm trying to do.

I greatly appreciate any advice!
