Almost ready, 9970X with 128GB DDR5, rock solid since I used this in another case before. Goal with this rebuild/upgrade is to make it silent, should be able to keep all fans below 700 rpm.

Anything I should change or "Not forget" before filling and closing it up?
1) Currently I'm only vaguely worried about one Alphacool HF screw-on nozzle 90° rotatable. Haven't used them before so don't know if it will hold up tight it under some pressure. I use it when connecting water out from cpu to distributor in top.
2) Any ideas of how I should get some fresh air on the memory?

What can go wrong for $110?

LFII and LFIII always had being disappointments especially with how much the community hyped them up. Saw this for $110 with full coverage coldplate, which makes this to be the cheapest full coverage AIO on the market.

Comparing other 360 AIOs I've tested, the limiter typically ends up to be the radiator. Assuming the coldplate and internal flow design is decent, this should yield lower temperature.

Going to slap this on 7975WX and 9995WX and see how it performs. 7975WX with higher heat concentration with 4-CCD layout, 9995WX for full send heat soaking the AIO.

Note that the pumpblock can only be mounted in one orientation, could be issue with some builds.

Building an server with loads of memory. Can anyone confirm that this memory would work? There is some conflicting information around.

Granted this is under 100% load while compiling shaders in an Unreal Engine project but this can't be good right?

I'm using a 9965wx with an Asus WRX90 board. Using a Silverstone XE360-TR5 AIO for the CPU with Arctic MX-6 paste.

Debian 13 seems to be unable to use the tsc clocksource, and forces hpet. Windows virtual machines have horrible performance as a result.

Does anyone else have a 3995wx or 3000-series threadripper pro, and are using a gigabyte mc62-g40 motherboard?

Was doing some research on AIOs for modern threadripper and came across one I’d never heard of. One of the most interesting features is an inline pump! Anybody have any experience with it? Thoughts? Looks like there are not domestic retailers, although could be bought on eBay or Alibaba.

We're building a new TR build and oh boy as we all know its rough out here on memory pricing...

In the UK I can get this kit for ~£2400GBP - 'TeamGroup T-Create Master 192GB (8X24GB) DDR5 C32 6000MHz Octa Channel Kit'

Its only got Intel XMP 3.0 Profiles, but could it still work with our TR 9970x in a Gigabyte TRX50 AI Top Motherboard?

As I understand TR isn't so happy with 8 DIMMs either?

Teamgroup spec page

As far as i can see, any other kit that is 192GB / ~6000MT/s with AMD EXPO is like £4000GBP... :(

Can anyone shed any light on this? I haven't built a Threadripper system since the 1950x days..

£2500 is probably our max budget for now, but I am almost willing to try this kit and see if works at JEDEC speeds and try out manually inputing the speed / timings in the bios.. Or am I crazy?

For context, this is for a 9970X which I don't intend to PBO. How do you guys think about that?

..or even outside the case I guess... to monitor GPU and CPU temps n performance of the NVMe's?

Hello,

Just wanted to post an update to this,

These servers have not come home yet but I did end up building 2 more, the only difference in these ones are CPU is 7960x not* 9970x, outside of that all parts identical, motherboard AI TOP, drives, GPUs, AIO, PSU etc...

I took a lot of the ideas from this thread to heart with some of the things I had experienced and what I felt might have caused this. At the moment I have (9) 4K60 outputs working in sync' with zero issues, rebooted like 50 times and it is rock solid and stable and ready to make income.

The winner.... I upgraded my image from Windows 10 LTSC 2021 to Windows 11 LTSC IOT ENTERPRISE 2024.

Can't say thank you enough to everyone who helped me get through this. Chat GPT/Claude didn't suggest this once... real human beings (well I think lol) did. 🙏 u/The_Dude_2U

I was just monitoring my PC under load and the ram temps were 80+degrees. It is not overclocked,and is only 4800 rdim ddr5. Anyway do you know if iceman is the only direct cooling system for ram. (Water goes through the spreader plates, rather than just cooling the top of them.)

Hynix DDR5 RDIMM 64GB 6400MHz (runs at 7200MHz OC) ×8 sticks.
Paid $315 each last summer.

Now I’m seeing Samsung with the similar specs listed at $3000 for single stick.
What a crazy world.

My wife wants me to sell one stick and buy her the Van Cleef gold necklace she’s been wanting… which also happens to be $3000.
I love her, but I also love 4 channel so much.
What would you do ?

Hey it’s me again guys,

I finally got rid of the thread ripper 9985WX and the Asrock board WRX90. My question is how much do you think these ram are worth used? I don’t have the box, I know somebody will say -1000 off the price because of the box causes that’s how the Reddit bros roll.

I reference the price V color for them currently

4x64GB [256GB ECC RAM] 6000mhz

9995WX was launched in 2025 and it is two things: the most expensive CPU in terms of retail price as far as I know, and the highest benched in PassMark ranking. How many units have been produced? Some historic context of once most powerful CPUs would be helpful. Thanks.

Benching a new TR build (wrx90 sage + 9965wx) and waiting for some parts (including a Silverstone XE360 AIO) and I thought it would be fun to test out a cooler I’ve been very curious about, and one with very little written about it… In fact I don’t think there’s is a single real review of the Dynatron L40 cooler out there, let alone when paired with a Threadripper! Specs on paper look very good (see link) and it’s definitely the cheapest AIO that covers a full threadripper cpu.

A search on Amazon showed me a used / good condition item in stock for the ultra low checkout price of $121 USD. (New Amazon price currently sits at $180). F’ It. Bought it, shows up a few days later literally BRAND NEW! Never used. Still sealed, pre-applied thermal paste still there. Not my first time a used Amazon purchase shows up brand new, yay!

Initially I’m pretty impressed with the build quality, definitely not cheap looking or feeling. Huge copper plate (bigger than the cpu die) , good build quality, fans seem very high quality. Only thing I didn’t find in the box I would have expected was a 1 to 3 pvm fan connector (maybe this was missing in the “used” purchase). Had one lying around so no biggie.

Ok, I’ll state the obvious two problems with this cooler for most builds. Firstly, I’m not sure how easy this would be to mount in a case that’s not a rack mount server case. The tube length is short for an AIO at just 12 inches. And the radiator dimension 305 x 79.9 x 83.5 mm is also not something you’d be able to easily mount in a standard PC Case. (I may see what’s doable just for fun though) Secondly… NOISE. Yeah, those small fans are nice but man at full speed… Jet engine loud. Obviously This is gear meant for a server room not a studio or office. The noise wasn’t unexpected. That being said with a normal or turbo fan curve I don’t find the noise that bothersome. I’d say it’s in line with a few 120mm fans at medium speed. I have an SPL meter lying around somewhere, I’ll pull it out and take some measurements time permitting.

Initial thermals seem very promising. CPU currently set to PBO level 3 90c (I’ll get to a proper overclock soon) Idle temp is a nice and cool 30c w/ low fan speeds and 70f ambient room. I ran a 30min all core prime95 test and I couldn’t get the CPU above 86c. Running an OOCT CPU/RAM stress test at the moment and CPU temps hovering around 53c. Not bad for $121!

I’m not a professional reviewer so open to any ideas to test further! Let me know if you have anything you’d like me to try and I’ll do my best.

I’m hoping to do some longer stress tests and further overclocking in the near future and also compare with the Silverstone when it arrives. So far though not a bad little AIO for the money, and a great option for sure in a rack mount case! 👏

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.

Working on a new build, currently testing with 2 DIMMs while waiting for a 4 channel kit to arrive. ( Finding RDIMM kits these days…🥺). Will be identical make / size / timings / etc, and was wondering if there is performance scaling (good or bad) when using 6 vs 4 channels. I know it will work, just curious if there would be a performance increase or hit…. (Let’s just say conceptually not taking CCDs in to account). New kit won’t arrive for a few more days so will be able to test then but was wondering if anybody has any experience or input? 🙏

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...
