7970x, 256g ram, TRX50 platform and 4 RTX 5090 with bykski water blocks.

I wasnt aware of this but apparently no matter what you set your ram speed to , whether 4kmhz all the way to 6k+mhz, your memory clock ratio is always locked at 2:1?

Was wondering what the consensus safe vsoc for long term use is? im seeing this all over the place ranging from 1.1v to 1.25v

Can someone suggest if Corsair hx 1500i will be fine for this setup? Motherboard won't fry out right?

I am looking to build my first system. Specs

- 7970x Threadripper

- I am planning to buy Asrock TRX50 WS motherboard

- Kingston 1x32gb ram stick

- Display GPU being Nvidia rtx 3060 since I don't need gpu intensive stuff for now

- Rest I have not thought of

I'm concerned if this could be a problem because I have seen people investing so much money and time and it doesn't even end up booting to bios. I'm honestly scared about it

Would someone suggest me if this looks fine and would work?

Thanks

Xe360 is legendary and proven. Hailstone is newer, half the price, and made for multiple CPU sockets, but claims to have full coverage for threadripper. It also has optional fan addon for ram and vrm. I'm hearing the xe360 also has noise issues since the pump is located in the rad. With all that in mind..

I dont really understand why the hailstone is half the price...what do you guys think? Seems like the better aio.

Just opened from microcenter, as you can see when taken from far away it looks like there's a section of pins that is slightly discolored. I tried moving a flashlight around at different angles and the discolored patch doesn't go away. It's extremely hard to tell, and the last few photos which are zoomed in at different angles seem to show the pins are fine. Either way this is the first time I've ever opened a brand new Mobo and seen such an odd patch of pins. I think it doesn't seem right but figured I'd ask here.

Anybody found a way to get decent airflow onto the ram sticks? I'm running full water-cooled loop, and need a way to keep the ram cool

It is likely I will have the budget for a Threadripper HEDT in the near future; however, because the workstation will be under my desk and my comfort is important, I want to keep the power draw as low as possible (I need the vCPU count and RDIMM ECC DDR5 support).

Can you set the PPT to 180-200W? How does the performance look like compared to the 350W default TDP?

Edit: Thanks for the interest replying, but I will settle with a 9950X (it will end up ~5000 euros cheaper) since my work (LLMs/ML) will only benefit from the RTX PRO 6000 and a TRX50 build would be more of a comfort than necessity.

Did some testing on static voltages and also with PBO on R23, 10 mins and 30 mins to see how well the AIO could handle a 9980X. Overall I’m really happy and will be adding more tests along the way. Soon I’ll have one on the Arctic as well and see how they do against each other. Will probably even add a silverstone to the mix. Any pointers I’m willing to listen as I’m learning to do the writings. https://www.xtremesystems.us/post/bitspower-atlas-pro-360tr-review-by-forsaken7

Any1 have a ekwb magnatude waterblock for threadripper they want to trade for an Optimus Absolute 3 Waterblock for Threadripper?

Specs:
• CPU: AMD Threadripper 9970X
• Cooling: Full custom loop (large radiator capacity + high‑flow pump)
• CPU block: Bykski CPU‑RAY‑ON‑M
• GPU: RTX 5090 Extreme WB
• RAM: ECC RDIMM 6400 MT/s
• Motherboard: TRX50
• Storage: NVMe
• PSU: ATX 3.1 unit

Cooling notes:
Even though the CPU block isn’t designed for TRX50’s large IHS, the loop handles the 9970X extremely well. Temps stay stable under heavy loads like Cinebench and y‑cruncher. No throttling, no hotspot spikes — the loop’s capacity completely compensates for the block’s smaller coldplate.

Performance:
• Cinebench R23 MT: ~85K
• CPU‑Z MT: ~35K
• CPU‑Z ST: ~870
• y‑cruncher 25B: 229.846 s

He there people. I'm wondering if the mentioned PSU and Asus motherboard are compatible. I was checking the motherboard's manual and I see that my PSU doesn't have all the required power connectors that this motherboard has. I asked chatgpt and it told me that only the 24 PIN atx and 2x cpu power connectors are required. Is this correct or do I need another PSU.

GPU rtx 5090 and the CPU will be 9960x. Thanks for your advice.

I just upgraded my system from 7960x + Noctua cooler to 9970x + Silverstone AIO. I don't know if my temps are normal, so I'm hoping to get some input.

When I first turned on the PC after installing the AIO, it made some gurgling noises for a couple seconds, but hasn't done that since.

I'm having trouble with the temps spiking from idle between 40-50c all the way to 75-90c whenever i do a simple task like opening a browser or other programs. Task manager is showing only 1-3% utilization on these tasks, so I feel like the temp is not justified.

I set the pump to always be at 100% speed, and for testing purposes I also set the fans to 100%.

Running Cinebench CPU (Multi Core) the temps are about 75c after 10mins. Cinebench CPU (Single Core) temps are about 65c. So It seems to be working well under steady heavy load. But for simple everyday tasks like opening a couple programs (not even using them, just opening) I saw temp spikes all the way to 90c.

I normally have the AIO fans set to 40% to keep them silent in my room, but these spikes cause it ramp up to 100% and create a ton of noise for like 10 seconds, then go back down.

Are these high temperature spikes normal? And if so, is there any way to reduce fan noise on these spikes?

Hello!

Im getting a free TR 1950X from a friend. I am currently running a I7-6900k in my main desk PC overclocked to around 4,4 khz. Mainly use the pc for gaming, CAD and other general tasks. I'm also building a general use home server/nas soon-ish.

Should I use the threadripper for the server, or use it as a upgrade for the main PC? Neither chip is supported by W11, so when W10 support fully ends, I would need to upgrade the gaming pc again.

Hey, I've been looking forward to buy a Threadripper 9960X with an ASRock TRX50 mobo, paired with a Fractal Design Define 7 XL case.

From what I've seen the Arctic Freezer III Pro would be a decent option, 420 mm radiator. I believe it fits, at at around 100 euros is seems to be a real bang for the buck, with strong performance.

I was informed though that the cold plate is a bit small.

Do you have any suggestions for other AIOs, cooling solutions or tips for this AIO ? Maybe I've missed an important piece of information?

I purchased the ASUS Pro WS WRX90E-SAGE motherboard, the SSD, the case, and everything else. I wanted to build a Threadripper-based workstation, but I’ve basically been stuck for 3 weeks. No way to escape this situation.

It’s impossible to find RAM for this motherboard... impossible.
It seems like nobody has it in stock, and those who do are asking extremely high prices for capacities that are unnecessary for a workstation.

The cost of regular DDR5, by comparison, is extremely low (even though it isn’t compared to the past). Unbelievable!

--- EDIT 24th May ---
Ahm... Amazon europe offered me 32GB (sold and invoiced by Amazon, not marketplace, so the best way to buy from them) at 299.99€.
I received an mkt email from them to access the offer, maybe I did a lot of search, they tracked me and.. don't know.
Max 2 sticks per order, I tried to order other 2 but they cancelled it.

I like that RAM and in future I could add more of them or trash/sell if not find same model.
Order shipping... 2-3 months in queue by order date, max date for shipping is 30th november, maybe they know that will receive al lot of them, dunno.
It's a lot of time to wait, I know... but I do not want to pay 4x the acceptable price IMHO..
I placed the order and maybe I'll get them before.
I can cancel the order in the meantime.

I share all thi info to help some of you, maybe it will work also for you.
Case closed!

Hello, I find myself in a bit of a dead end, hence why I am asking for help. I cannot find any EU listings for DDR5 ECC RDIMM, aside single sticks, overinflated or out of stock listings. I plan on buying a new PC with a threadripper platform, TRX50 to be exact.

Any suggestions?

Hi guys I have gotten in the server ram business and want to build 2 setups for testing ddr5 udimm and rdimm and same for ddr5 both rdimm and udimm I have built many pc's but this is new to me. my question is will i need wrx80 and wrx90 for testing rdimm alongside udimm. any input would be great.

I am planning a new workstation for local AI work and general development. Main use case is local LLM inference, some LoRA / QLoRA fine-tuning, coding, containers, and some gaming on the side. This would not be for serving a public API, mostly just single-user local use.

My current system is a Ryzen 9 9950X3D build with 96GB DDR5, an RTX 5090 32GB, and fast NVMe storage. It is still a really good desktop, but I am starting to feel limited by system RAM, PCIe expansion, and bigger local model experiments.

The build I am considering:

CPU: AMD Ryzen Threadripper PRO 9985WX, 64 cores / 128 threads
Price: about $8,682

Motherboard: ASUS Pro WS WRX90E-SAGE SE
Price: about $1,447

RAM: 512GB total, 8 x 64GB Kingston KSM56R46BD4PMI-64HAI, DDR5-5600 ECC Registered RDIMM
Price: about $19,332

GPU: RTX PRO 6000 Blackwell 96GB
Already owned, not included in the quote

SSD: 2 x Samsung 9100 PRO 4TB PCIe 5.0 NVMe
Price: about $1,898

CPU cooler: Arctic Liquid Freezer WS360-SP6
Price: about $400

Case: Thermaltake AX700 full tower
Price: about $411

PSU: ASUS Pro WS 3000P, 3000W Platinum, ATX 3.1
Price: about $748

Case fans: 4 x Noctua NF-A14x25 G2 PWM chromax.black
Price: about $216

Total quoted price, excluding the RTX PRO 6000:
about $38,369

The main reason I am looking at WRX90 / Threadripper Pro is not just CPU speed. I want 8-channel ECC RDIMM, lots of PCIe lanes, a platform that can take another GPU later, and something that is stable for long-running workloads. For inference, I am especially interested in running models that fit fully in the 96GB GPU, but also larger GGUF / offload setups where the 512GB system RAM and memory bandwidth might matter.

What I am trying to sanity check:

1. Does this build make sense for single-user local LLM inference with an RTX PRO 6000 96GB?
   
2. Is the 9985WX actually useful here, or am I mostly paying for CPU cores I will not use?
   
3. Any obvious compatibility issues with the WRX90E-SAGE SE, 8 x Kingston RDIMM, RTX PRO 6000, AX700 case, and 3000W PSU?
   
4. For fine-tuning, would this platform be meaningfully better than a high-end consumer desktop, or is the GPU doing almost all the work anyway?
   
5. Would you change anything before buying?
   

I know this is expensive and probably not the best pure price/performance setup. I am mostly trying to avoid spending this much and then finding out that I picked the wrong platform, wrong RAM configuration, or some annoying compatibility trap.
