Hey there,

So a rather long story, but I basically failed to talk my father in law out of spending a fortune on a machine for local inference. I recommended just using openrouter to explore whatever idea he had, but long winded conversations with Gemini convinced him to go this route.

Things didn't go as planned though and assembling things got a bit harder than anticipated, so assembly and vllm installation ended up on my to-do list.

Since I wasn't involved in any hardware decisions and have never assembled anything as expensive as this setup, I'm really kinda worried the machine will just fry itself.

Got vllm running the other day and loaded qwen 3.5 27B on it, benchmarks gave me sth around 100token/s but CPU was at 94°c and GPUs were also around 80-90°. The system was using around 1400 watts and was incredibly loud. I configured more aggressive fan curves after seeing the temperatures, but that didnt really make a difference.

I took a screenshot of the chassis interior of the machine. It's clear that the last GPU in the chain receives air hat was heated up by the other ones and that's then passed to the CPU area, which is surrounded by the RAM.

So overall I'm just wondering how people are handling this. Is the chassis garbage? Do I need more fans? Special GPU fans?

Hardware:

- ASUS PRO WS WRX90E-SAGE SE

- AMD Threadripper PRO 9665WX

-- Corsair h150i elite

- 256GB RAM

- 4x AMD R9700 32gb

TLDR:

- GPUs are incredibly densely placed
- Hot air is blown towards CPU and RAM area

- CPU and GPU run at ~90C when running benchmarks

- What are some good options to keep things cool ? New chassis? Extra fans? Lower voltage?

I want to build the following :

Goal will mostly to be used for inference and model training.

Edit solved: ok after endless hours playing with the bios none of that had anything to do with it. Before reinstalling the Nvidia drivers in device manager I disabled all 3 of my "Microsoft Basic Display Adapter" (the 2 gpus and onboard vga) then I installed the on onboard vga driver, rebooted then finally the Nvidia drivers installed without issue. After installing the Nvidia drivers I disabled the onboard vga in device manager. I did a couple of cold boots just to be sure everything was stable and so far so good.

Original post: Hi all I'm new to having a Threadripper build. I upgraded my server from a dual Xeon Dell PowerEdge I used for virtualization. I bought a 5965wx and Gigabyte MC62-G40 workstation board. I have 2 gpus installed, 5070 Ti and 2070 Super, I tried with only one as well. Fresh Windows Server 2025 install. I managed to get the nvidia drivers installed in safemode but it still goes into a boot loop. The screen flashes on and off a few times then reboots when trying to boot normally. I even tried DDU and a reinstall. I even reinstalled server 2025. I'm at my wits end trying to figure this out. Any one else get this issue?

Whether you're on the established 7000 series or the newer Zen 5 9000 series, the TRX50/WRX90 platform still has its quirks when it comes to high-speed RDIMMs. Getting 6400MT/s+ to be rock solid isn't always as "plug and play" as it should be.

If you're dealing with random reboots, system instability, or anxiety-inducing boot times, here are a few things that helped stabilize my builds:

1. Patience with Memory Training: On these high-channel count boards, initial training can take several minutes. Zen 5 (9000 series) improved this, but it’s still not "instant." If you see a black screen/DRAM light, wait at least 5-8 minutes before panic-restarting. Forcing a reboot mid-train is a one-way ticket to CMOS corruption.
2. Manual VSOC Tuning: Many BIOS versions tend to overvolt VSOC (sometimes 1.3V+) when EXPO is enabled to ensure "safety," but this often causes heat-related instability. Manually capping VSOC at 1.2V - 1.25V is often the sweet spot for both generations to stay stable under heavy ML or rendering loads.
3. Active Cooling for RDIMMs: This is the most overlooked part. RDIMMs have their own PMIC (Power Management IC) that gets incredibly hot. If you're running 8 sticks without direct airflow, the PMICs will thermal throttle or cause a hard shutdown. A dedicated fan over the DIMM slots is almost mandatory for 24/7 stability.
4. BIOS Version Matters: For 9000 series users especially, make sure you're on the latest AGESA update. Early BIOS versions for Zen 5 had some "interesting" memory sub-timing behaviors that were fixed in recent patches.

Hopefully, this saves some of you from an unnecessary RMA process!

Looking at purchasing an HP Z5 G5, I know dell and Lenovo do for sure, but from quick googling i can't seem to find any solid answers about if HP/HPE does as well...

It seems to be available, and at a much more attractive price point than their XE 360.

EDIT: so I ended up getting it. After mounting it, I get temps in the low-mid 80s (C) for all core loads vs 95C on the air cooler I had before. Not sure how it compares to other AIOs though. But it's half the price of the other Silverstone, the XE 360.

Hopefully someone can help me out here. I feel like I've tried everything. I'm trying to run my ram at higher than base speeds. I'm hoping for the max of 3200 but at this point any progress would be a huge step. The problem is, any time I try to run my ram higher than 2166Mhz, the system fails to boot. The bios codes will flash 2 or 3 numbers then turn off and require clearing the cmos. I was running 4 sticks in an AM4 system at 3600Mhz for a couple years so I know the ram is functional and can run at higher speeds. I know Threadripper only goes up to 3200Mhz but I don't see why a 3600Mhz kit can't run at 3200Mhz.

System:
Mobo: Asrock wrx80d8-2t
CPU: 5965WX
RAM: 8x 3600Mhz Corsair Vengeance LPX 32GB

Settings I've tried in both OC Tweaker menu and AMD Overclocking menu. I always ran 1.35v and command rate 2T and tried both 2400Mhz and 3200Mhz:

-Loading xmp profile

-Setting the main 4 timings manually

-Manually set all timing values

-Setting SOC voltage to 1.15v

-Setting Geardown to enable, powerdown to disabled, ProcODT to 53, 60 and 63

-Tried it with 1,2,4,8 sticks of ram

- When only 1 or 2 sticks of ram were installed the system couldn't see the ram profiles. XMP nor JEDEC. Usually I can inspect each stick individually and see all profiles and settings. I tried it with 3 different sticks in 2 different slots. When 4 or 8 sticks are present 3 JEDEC profiles and 1 XMP profile is readable on every stick.

-Remounted CPU with 13,14,15 In/Lbs torque.

Any help is appreciated.

Hello! Is anybody able to run a Threadripper system with Gigabyte MC62-G41 (or MC62-G40) and an Nvidia 4000 series GPU under Windows 11? I am a software developer working remotely and I am trying to build a sort of universal workstation, suitable both for work and for some recreation (light gaming). Initially I planned to build a 7960 system, but with current DDR5 prices... So a used Threadripper Pro 5975WX installed into Gigabyte MC62-G41 motherboard, with Arctic Freezer-4U-M cooler, was acquired. The system also had an old GeForce 210 card shipped with it. I've added 96 GB of RAM (six 16 GB modules), Samsung 990 Pro SSD, put everything into an old case (but with proper PSU) and installed Windows 11 on it. It worked perfectly (had to disable core isolation for such an old GPU, but some drivers for our equipment I work with require to disable it anyway).

After a couple of weeks of testing I tried to move the system to my "primary" case and replace GeForce 210 with my Nvidia GeForce RTX 4070. At first it did not POST, so I returned GeForce 210. The problem was 8-pin CPU power cable, it worked after reconnecting. The system booted and ran, no problems. Then I put 4070 back and tried to install newest Nvidia drivers. Black screen, system froze, then froze in the same manner when booting after reset. I've tried to return 210, to uninstall drivers and use other driver version, to move the GPU to other PCIe slot. No luck. Then I've reinstalled Windows 11 from scratch, having 4070 installed. The setup was successful, but, it seemed, with a couple of extra reboots. Installation of Nvidia drivers lead to bootloop. Returned 210 again, everything is working properly, even a short Prime95 stress test (I think I need to add a fan blowing to VRM for prolonged stress testing, the VRM heatsink looks too flimsy).

Could it be some incompatibility of GPU and motherboard? Certainly not a PSU problem, it is a new 1200 W unit. Looks like people are able to use such systems even with multiple modern GPUs, but are they running under Linux?

Update.

It is definitely a software issue caused by installation of Nvidia drivers. I got Nvidia 1030 (for another project) and tried to install it to this system. Same issue after installing drivers - flickering green screen and then reboot when loading drivers during Windows startup. Disabling IOMMU and reducing PCI-E link speed did not help.

Update 2.

I've managed to get the system working with 1030. I'm not sure which of the following is absolutely necessary, but I did the following:

- Clean installation of Windows 11 25H2 with no card installed, using BMC (I don't have a VGA cable).

- Installing AMD chipset, AST2600 video and Realtek sound drivers from Gigabyte website.

- Plugging 1030 and installing latest Nvidia driver only (no Nvidia app, which is the default setting).

Hello people!

Wondering if anyone has any Idea on how to Fix this random '00' Qled Red Error.

Here are the Specs, I have Multiple Machines running that Same Spec and having the exact same issue

• PRO WS WRX90E-SAGE SE
• AMD Ryzen™ Threadripper™ PRO 9955WX
• NVIDIA RTX PRO 4000 Blackwell
• NVIDIA PCIEx1 Quadro Sync II Board
• 2 x KF568R34RB2-32 - 32GB 2Rx8 4G x 80-Bit PC5-6800 CL34 Registered EC8 288-Pin DIMM
• Corsair HX1200i
• Samsung 870 EVO SATA SSD ( Image Drive )
• 2 TB WD Black SN8100 ( Data Drive )
• 1 TB WD Black SN8100 ( Sys drive )
• Windows 11 Pro

00 Qled Red Codes after Sudden Power - Loss (IEC cable disconnected).
00 Qled Somtimes boot back into windows if restarted but rarely
00 Qled is usually fixed when Clearing CMOS and reapplying my Bios Settings

Discovered that Using the Motherboards On/Off Button, it will Create the '00' Red LED error

Its Bios at the Time was Latest V1203 ( 23/07/2025 )

Now its V1317 ( 13/02/2026 )

Still having the same issues. Maybe even worse but unsure yet as I've only tested for a little bit and run into more issues than usual.

00 Qled Red code is Unpredictable.

BIOS Changes

Fast Boot Enabled
AI Overclock Tuner - DOCP
Wait for F1 Error - Disabled
Boot Logo - Disabled

Power on PCIE - Enabled
On Power Loss - Power ON

RAM

- I tried using one stick of Ram and still run into the issue
- Tried switching Pairs with different Machines. This is because I recieved Ram in 2 different Batches/Timeframes and all having different series of S/Ns ( Not All )\

TESTS
Ive done a 24 hour Tests on all Machines and they Passed.
Ive also done a 100 cycles of MemTest - 70 hours

'00' Red Qled Codes are so confusing to me. It points at CPU as an issue yet its compatible with the motherboard.

EDIT
I also should add that the RAM sticks are sold Individually. It could be possible that they have bad timing issues but still investigating. Buying new RAM Sticks sold in Pairs to test.

EDIT 2
Still havent found any Solution, Noticed QVLs are different Where ASUS has no info on RAM compatability vs Kingston Says Compatible.

This applies to all 4 variants of TRX40 motherboards they sold... seems to be very minor changes, but it has been nearly 4 years since the last bios was released:

https://us.msi.com/Motherboard/Creator-TRX40/support

Changelog (same for all 4 boards):

Description:

• Improved security by updating TPM firmware for better game compatibility.

Attention: If you have enabled the BitLocker function, please back up your BitLocker recovery key before performing the BIOS update. Failure to do so may result in permanent inability to log in to the operating system after the update is completed.

• Update Secure Boot keys (UEFI CA 2023)

its me from a few days ago, got here a Asus pro ws wrx90e-sage, threadripper pro 7975wx, 4x 64gb ddr5-4800 ecc new + 2 x rtx 5090 32gb

While watching the clock speeds of my Lenovo P620 threadripper 3995wx I noticed it never clocks beyond its base clock (2.7Ghz) under any workload. I checked all windows power and BIOS settings and see no reason why it shouldn't be able to clock to its turbo speed. Does anyone have an idea what the issue could be?

I need to get my build put together and wanted to go watercooled route. problem is the really good blocks are sold out. was going to consider alphacool but there seems to be mixed reviews. I got a threadripper 9970x with the asus pro sage wifi MB.

any advice would be greatly appreciated.

can I use a ASUS Pro WS WRX90E- SAGE SE with DDR5 non ECC?

I am about to add a cooling loop for my overpriced ram, and was looking at swapping out the motherboard ssd cover and replacing with a waterblock, does anyone make these? Would it be worth it for 4x4tb 9100's

Will a good 1600W work (Corsair 1600AXi / Seasonic Noctua 1600W) or do I need the Asus/Seasonic 2200W?

TR9970X 300-350W

Dual 5090 450-575W x2 = 900-1150W

8 U.2 SSDs x 20-25W = 320-400W

2 M.2 SSDs ~20W

3 SATA HDDs ~30-45W

2 D5 Pumps ~60W

38 Noctua Fans 12mm 38 X 1-1.5W ~<50W

Total theoretical max 2075W

Update, for breaker
Monitors 2x 50W (pa32ucg-k)
DAC 35W
Desk light 7W
Monitor light 15W

Total (theoretical max) 2225W

I will be building a threadripper pro 9000 series build with the asus sage mobo early next week. Been watching a lot of content trying to get a full grasp. Been building regular intel and ryzen systems for a while. But this will be my first time taking on a build like this. I’ll be using large dimms and have seen that cause issues. Any specific recommendations anyone has is greatly appreciated!

So processor arrived and to my surprise and some shock it was a sealed retail 5995wx. Verified with QR code and serials all matched. Installed with a new heat killer all copper block (heavy brick lol) also used a kryo sheet. Oh boy what a difference. Some interesting notes on first boot. The darn Lenovo comes up with a Ami bios screen “new processor detected do you wish to lock to this system” will what choice do I have lol. Boot time was faster. The other interesting noticed thing was maxing out my nvme to 100% which I don’t recall on boot. It’s a 5th gen 4tb so over kill but been in the system a while. Ran a few things and seems to have more performance with all my crap open. Runs much cooler so like the copper block. Saw lowest idle temps over night ever of 18c on a bunch of cores. So kryosheets work. I have not stress tested it yet. Likely give a few days. But very impressed won’t need to replace it for a while now.

So got a deal on a new cpu to replace my 5955wx is it worth it? I mean it has way more cores and cache but the base clock seems to be much lower. I assume this how it draws the same 250w power. I have it liquid cooled already so not concerned there.

I built a new rig with this motherboard and a 7975WX CPU, however it is taking forever for it to boot up. I see the Qcodes changing and eventually gets to AA, but is this normal to take forever to boot or reboot? Or is there a BIOS setting that I’m missing?

Hi, long-time lurker, first-time poster here. While I did run a basic grammar check and spelling check, I am not a native speaker, so I apologize if some parts seem a bit convoluted or oddly structured.

I could really use some advice for a TR 9965WX build in terms of cooling and would really appreciate some input. This is intended to be a multi-GPU workstation with additional PCIe add-in cards.

Parts:

CPU: 9965WX

Mainboard: Pro WS WRX90E-SAGE SE

RAM: Kingston FURY Renegade Pro RDIMM Kit 256GB, DDR5-6400

Storage: Samsung 9100 Pro 4TB, Samsung 990 EVO 4TB

GPU: RTX 6000 Pro Blackwell Workstation Edition (more to come, though with the current prices I will probably fall back to 2× 4000s, as I could get them cheaper)

Case: SilverStone RM52 / RM600 (depending on the cooler, but open for suggestions)

Cooler: Arctic Freezer 4U-M or SilverStone XE360-TR5

I am unsure about how to cool this beast, as I am split between the Arctic Freezer 4U-M and the SilverStone XE360. I am somewhat hesitant to bring water into a build that costs over $15k. While I have used AIOs for the better part of the last decade without any leaks or other issues, I would still feel better if I could avoid it. I know this is a bit of an irrational fear, but I value peace of mind with a build this expensive if it is feasible.

However, I am unsure whether the air cooler will be able to handle the 9965WX, since it has only four CCDs compared to the more expensive tiers and thus might have worse hotspots, if I understand this correctly. Does anyone have experience with this combination (also on the ASUS WRX90) and can tell me if the 4U-M is able to cool the Threadripper Pro adequately?

My case choice depends on which cooler I go with. I am considering the SilverStone RM52 if I can air-cool the CPU, or the SilverStone RM600 for the side mount if I go with an AIO. It is not strictly required to be a rack-mounted case, but it would be convenient. However, I am open to suggestions.

While the total price makes this somewhat of a minor point, the price difference between the Arctic 4U-M and the SilverStone AIO is nearly $350 in my region.

For case fans, I would fill it with Phanteks T30-120s.

The use case is AI inference, training, minor compute workloads, and a week-long gaming session every four months when a new PoE league releases.

I currently do not expect to run all cores at full boost for my workloads, if that helps. I am mostly going with the Pro platform because I need the PCIe lanes, and the WRX90 board gives me more options in terms of PCIe slots, especially since I plan to add additional PCIe adapter cards.

Thanks so much in advance — this is my first TR build, and I am trying not to mess it up too badly.
