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:
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.
I picked up a cheap ‘faulty’ workstation on FB Marketplace with ‘no boot’ issues.
It’s an ASRock X399 Taichi with an AMD Ryzen Threadripper 1950X and 4x8GB 2400MHz Corsair Vengeance LPX DDR4.
I’ve been tinkering with it with mixed results.
On the first boot after buying, the debug code kept reverting back to 00 and power cycling. I swapped around the RAM, PSU, and reset the CMOS, which changed the behavior slightly, it still looped on 00, but no longer shut down between cycles.
I then flashed the BIOS, checked the error codes with no RAM installed, and inspected the socket for bent pins. With no RAM installed, it produced a different code, so that seemed somewhat promising.
After some more tinkering, including physically holding down an air cooler onto the CPU, I finally managed to get into the BIOS. Everything looked normal there, and I was even able to restart successfully with all four DIMMs installed.
I then fitted a spare AIO and managed to get it back into the same BIOS-booting state by manually tweaking the Torx screws.
The next issue appeared when trying to boot Windows. I tested both a Windows installer USB and an SSD with Windows already installed. Both devices were recognised, but as soon as the Windows splash screen appeared, the system instantly reset and the boot loop returned. After each reset, it would eventually come back to the BIOS.
At that point, I figured it must be a mounting pressure issue and that I needed the correct torque setting. I got my torque wrench, set it to 1.4Nm, tightened everything properly… and now I’m back where I started: stuck in a constant 00 boot loop and unable to even reach the BIOS again.
I’ve repeated all of the above since then, but no luck.
Sorry for the essay, but does anyone have any ideas? I’ve been building PCs for about 20 years and have built 60–70 gaming PCs, workstations, and GPU render farms but this is my first time dealing with Threadripper and I’m running out of ideas without a spare board / cpu.
Hey all! Wanted to get the community's feedback on this rig for sale:
It's $6,400. Seems like a good deal especially because the RAM kit alone is selling for half the cost, but RAM prices have been all over the place lately. I already have two Threadrippers (3960x/3970x) that work great, but I want to upgrade to a PCIe Gen 5 platform as I play around with LLMs quite a bit.
Any feedback would be welcomed. Thanks in advance.
These were announced some time back but I have not seen any reviews
Price/ram ratio wise they are cheaper than 1TB, so I'm thinking if it is viable to use this for 2 machines - 1TB each with lower memory bandwidth. I am aware that none of the OEM builds support the full 2TB configuration even though TR supports it, I suppose heat issue is the main factor
Hi everyone,
I\`m currently in the process of replacing my old Yamaha A720, which is paired with ELAC Debut Reference DFR 52 speakers, with a NAD C700 V2. The main use case will be office work, Windows system audio playback, and occasional Hi-Res music listening via Tidal, etc.
I\`m wondering how to connect it via HDMI, as I\`ve read that it won\`t work properly with a PC. I could use the optical TOSLIN connection, however I\`ve heard that it may not provide full audio quality, and the salesperson at the audio store advised against that connection.
Right now, my Yamaha is connected via a 3.5 mm jack to the ALC 1220 onboard audio. One of the reason
I\`m buting the NAD is to have everything integrated in one device and avoid buing an external DAC.
What would be the simplest and most reasonble way to ceonnect it so that everyting works properly and seamlessy? :)
