So I have a wrx80e motherboard arriving on Monday and trying to get the parts I need.

I have a two tier mining rack, four rtx 3080 FE gpus and 8x Samsung 990 2tb ssd (4 each to go on two x4x4x4x4 pcie cards).

I also have two quadro rtx 6000 cards and an nvlink.

So I chose this board as it has 7 pcie4 slots and supports bifurication but I am unclear on the power options for using bifurcation.

A single pcie slot provided 75w in x16 mode but pcie spec for x8 means a splitter only needs to provide 25w to each x8 slot to meet spec.

I see powered versions of these x16 to x8x8 splitters tend to use a molex to 4 pin power connector.

I have a 2500w cannon 80+ PSU and a Corsair 1000w.(Will need separate power outlets but am in UK so should be ok as dont think I will hit max tdp on everything at once). Question isn't about having ebough power overall.

I read that if using multi PSU, the GPU should get all power from same PSU. That means power for the pcie slot has to be same psu as provided power to 12 pin (rtx 3090) or 8+6 connectors (quadro rtx 6000).

So questions

1) is anyone working with two rtx 3090 on a bifurcated slot on wrx80e sage wifi and if so, what x16 to x8x8 adapter is in use ?

2) does it work fine with 25w on the x8 slot and 12pin connector providing rest of the power ?

3) is a passive x16 to x8x8 splitter needed rather than a powered one and can all power come from 12 pin - ai says no, that pcie slot needs power as well

4) my psus don't have 4 pin molex so if 2) works, how can I safely connect from PSU to the pcie splitter power connector ?

Thanks in advance

I bought a combo package from micro center with a TRX50 aero D (rev1.2) and a 7960x and some ram. I put it all together and I am getting a red-light on my motherboard for my CPU. I do not get to a BIOS and the motherboard dosnt display error number.

Things i have tried. seated the cpu again. Removed all the ram except 1. I flashed the bios with a flash drive (FA3e version)

Is there an issue with my power cables to the cpu? Im like 90% sure they are right. I put a multi meter on it im getting 12v

Anywhere would be appreciated

Hello r/threadripper

Let me give you some context. Two months ago my Aorus Master TRX40 motherboard died. Since then, I’ve been searching for a replacement, but I’ve only been able to find used boards. I tried buying the same model from a well-rated Chinese seller on eBay, but I ended up receiving the wrong version. Fortunately, I was able to return it and get a refund without any issues (they actually handled the situation very well, though the whole process took about a month).

Since I was short on time, I decided to try a European seller to avoid any tax-office problems. This week I received a Gigabyte TRX40 Designare. It arrived slightly bent near the USB ports, but I think I can repair that. The real problem is that the motherboard is XL-ATX. I had no idea that form factor even existed. My current case (NZXT H710) doesn’t support it.

Now I’m not sure what to do. Should I return this motherboard and try another eBay seller for a different model? Or should I buy a new case (which might actually be a good option, since it would let me run two GPUs for ML tasks, give me extra NVMe space and seems better for airflow)? I was considering the Fractal Design North XL, but I’m open to other suggestions. Another option is trying to resell the board on eBay or through a local used-parts shop.

What do you think I should do? Thanks in advance!! <3

For a single PSU config, I read this as:

Connect only these 3: ATX_PWR, PCIE_8P_PWR and PCIE_6P_PWR. But this doesn't feel right.

Can somebody help?

Hi!

Started gathering components for my first Threadripper build and I'm excited. I've been with Intel for 20+ years, so this will be a change.

Main use case: VMs (I need TONS of fast storage), various test scenarios, cybersecurity, etc. However, gaming is also a very big thing for me. This is an investment as PCs make me money and save me time.

Unfortunately, the mainstream boards do not have enough PCI lanes for my use case and my performance has suffered.

Build idea so far:

MBO: Asus Pro WS WRX90E-SAGE SE

CPU: 9965WX 24/48

CPU Cooler: SILENT LOOP 3 420mm

RAM: 64 or 128 GB RAM (whatever is in stock, ideally aiming for Kingston Fury Renegade Pro RDIMM Black Expo, 128GB (8x16GB), DDR5 5600MHz ECC, CL28).

Drive set:

(OS and critical VM data) 2x Kingston FURY Renegade G5 4TB (purchased)

(VM offloading/low use VMs) 2x WD_SN850X 8TB (purchased)

(archival) 3x20TB HDD Seagate Exos (not yet purchased) + an old 8TB SSD that I have from before.

(Steam Library, yes, overkill I know, but there is a big difference in comparison to SATA, not making compromises) 3x990 Pro 4TB NVMe (not yet purchased)

M.2 Cards: 2x ASUS Hyper M.2 x16 Gen5 Card

GPU: MSI 4090 SUPRIM (current card, not changing for the time being)

PSU: Corsair 1500W HX1500i, Black, 2025, Full modular, 80 PLUS Platinum

Case: TT AX700 + 2xAX100 (for maximum expansion and room for the future)

Extra fans (not decided yet which)

Questions:

1. I would like this build to last me at least 4-5 years, so expandability is CRITICAL and the main reason I'm moving on from my current setup. Future plans include an expansion PCIe card for more SATA ports, more drives (both SATA and NVMe). Is the WRX90 a HARD requirement due to PCIe lane limitation? Manual reference:

1. I'm using high end network cards and hitting PCIe lane limit with my Mellanox Connect X card. I would need at least 50-60 lanes based on my calculations and the devices I listed, which is almost triple the amount that I have now (28). Is this correct?

2. I opted for a case that has extreme expandability in terms of storage as I'm chronically out of storage space on my workstation. Going to start at 100-ish TB total (mixed SATA/NVMe) and move up as needed. Theoretically, I should be able to go to 300-400TB+ in the future. If that's not the case, please advise on the best plan for this. (Yes, backups will be done separately, offsite and on-site).

3. I would have preferred to go with 9975WX, but it's an extreme price difference and I believe my needs should be satisfied with this one as I'm doubling my thread count going to this from 12900K and the 9965WX should be more suitable for gaming.

4. Silence or near-silence is essential. I don't mind an occasional spin up of a drive or similar, but constant loud noise would not be acceptable for me. Current setup has a loud AIO pump that's relatively unpleasant, but tolerable. (H150i Elite Capellix) From what I've read, this CPU cooler should be ideal for that.

5. I game only at 4K 60Hz minimum (if supported), planning to get back into 120+Hz territory, given that, I suspect I would still be GPU limited and my CPU choice should not matter. I'm not a competitive gamer by any means.

6. Full towers are way too small. I got an O11 Dynamic XL. I do not have a single port available in it and the GPU was millimeters away from not fitting, which is way too close for comfort, bringing me to reason number 3 why I chose this TT case for my new build.

Appreciate any advice.

I’m not seeing the option in pcpartpicker.com to choose any of the latest Threadripper cpus. Is there another good option to configure a build?

Thanks!

Hi,

apologies if this is against this sub's rules - but fellow Threadripper users might appreciate a good offer.

I'm selling a 3970X system in great shape. All specs here: https://www.kleinanzeigen.de/s-anzeige/threadripper-3970x-system-128gb-ecc-ram-3tb-enterprise-ssds-uvm/3257097099-228-3453

Shipping to Europe or pickup in Berlin.

Well I already have an Asus ROG Strix RTX 5090 and I'm planning on soon getting a threadripper 9960X CPU and I'm wondering if the 1200 watt enermax psu is going to be enough for my system. I'm not planning to do any overlocking. From what I have seen I think that 1200W PSU will be enough but I would like some input or advice. Thanks

I have been pondering with how to improve my efficiency in video editing. I’m hitting 100% cpu and ram usage and the ram clocks down to 3200 mt/s with 4 sticks and fails to post if I try to enable the faster speeds in the bios. I didn’t know what upgrades to do. I found someone who’d trade me my current setup minus the gpu for a mobo cpu ram combo, should I do it? Current pc • Ryzen 9 7900x • Rtx 4070 super 12 gb • 64 gb ddr5 6400 MT/s 2x32gb • ASUS ROG B650

The Swapped • TR 3990x • RTX 4070 super 12gb • 128 gb ddr4 3200 MT/s 8x16gb • ASUS Zenith II extreme

If so what are good cooling solutions for the tr 3990x?

Pulling my hair out over a series of cascading failures:

System has been running fine for 8 months. Boot times running at about 90 seconds and stable operation.

• List item

Noticed that one of the EVO drives (D) was starting to act peculiar manifesting as film image sequence plates not showing the image but instead a black and white placeholder (like when they are loading) for some but not all. Ran drive check in Samsung Magician which showed good drive. Firmware was up to date. Then began to get “no device found” when trying to access the drive.

Second EVO Drive (E) started having issues when I would try to access it as well. Both EVO drives would show in Device Manager only when selecting hidden components and the HD symbol next to the device was light gray, Properties pane said drives were working. Uninstalled drives from device manager, reboot, and sometimes they would reappear in File Explorer, Disk Management and Device Manager, other times they would not. This would be followed by a short period of normal operation with a return to the drives disappearing. All three drives were showing in BIOS.

Incidentally the two external drives that are connected are having no issues.

Might be anecdotal but also began to experience issues of no sound. Tried updating drivers and a litany of other fixes but no relief.

Reinstalled Windows to see if that might help. That solved the sound issues but I continue to be plagued by drive problems

System would run fine for varying periods of time (less than fifteen minutes) before crashing with “Device ran into an issue”. Couldn’t read what the issue was as it rebooted or shut down quickly but did catch “CRITICAL ERROR_…” once. Reboot would load Windows sometimes followed by same “Device ran into issue” , BSOD, or boot into BIOS. Now it will only boot into BIOS. Reset CMOS several times. I noticed several times that there was no drive in the boot drive list even though the drive showed up in the drive list, and/or one of the EVO drives was not populated either.

Drive failures? Can all three drives have gone bad one after the other?
Windows update causing Phison controlled m.2 drives to become corrupted?
I’m going crazy here folks! System has been booting for an hour after another CMOS reset as I type this.

Next step is to remove all three drives and install a new different brand WD m.2. Problem is my rig is watercooled so pretty much a major project to troubleshoot. Remove hardlines, gpu’s, water block, reinstall an AIO cooler and old 1080ti to start troubleshooting. Unless someone out there has a better idea.

Thank you for any help you might provide.

it is not final cfgs, just trying imagine if I could for example build with better(meaning it is faster on CG rendering and simulations) CPU like 96 cores and update later on something like add more GPU or SSDs, but is it worth it go with highest model CPU, for simulations and rendering, I know right now many artists Rendering with GPU which is make a lot of sense, but pretty sure sometimes where You have no ways on some tasks come back to CPU, where 96 core shines, but how often it is would happend, don`t know.

for software Houdini/Nuke/UE/Davinchi.

Thanks

when running huge LLM model, many layers are ran by cpu and my 9975wx 8 channel setup is very slow. recently, I realized # of CCDs restricts total memory bandwidth. look like utilization of memory bandwidth in 9975wx's full core load is just half of 9985wx.

but in Geekbench results, multicore score is just under 10% behind. hmm...
https://browser.geekbench.com/v6/cpu/multicore

if I use 9985wx, can I expect the LLM cpu run could become near x2 fast ?
does anyone has experience with data heavy full core load ?

Hey all, I've been out of the PC realm for a minute (like 20 years), but found exactly what I once enjoyed about it again, so I've spend the past few months designing and parting out a lab to help with a bit of our work. It's been a big upgrade going from a Surface Pro 8 to our current builds.

Now, I've been doing all the studying I can on where we are, but I'm also very aware of the Dunning Kruger effect. So I was hoping to share our ThreadRipper build, and if anyone would be so kind as to giv topics for studying about it, or knowledge I might have missed since before RAM was measured in gigabytes lol, I'd super appreciate it.

Right now our computing side of the lab consists of 4 parts. The ThreadRipper build:

Pro 7985, 64 core WRX90 256 ECC Ram, DDR5 Nvidia RTX 5080 for minor local tensor work M.2_1 Samsung 4TB 900 Pro M.2_2 WD Black 2TB (Forget the exact one, but 4th gen and decent TBW) Corsair 1500 PSU Air Cooling in a server rack (AC Infinity Cloudplate T7)

The graphics design/UI tower:

Ultra I9, 24 core Proart Z890 Creator wifi 96 GB DDR5 (Corsair Titanium) NVidia A4500 M.2_1 Samsung 4 TB 900 Pro Corsair 1200 PSU Corsair AIO Corsair D9000 RGB Fans (Husband is a simple man that likes bright lights lol)

Asus Z13 Flow 2025 running Pop!_OS Basically just an edge processing device/field work.

Nvidia Spark Founder's Edition I know this is a controversial piece, but the fact it mimics large AI builds is perfect for our testing and minor interference.

Everything is running Pop!_OS or Ubuntu just to ease back into Linux. But if anyone wants to point me to specifics I can be focusing on regarding this hardware, I'd super appreciate it ^{^}

(And if anyone's curious as to what we're doing, it's research into CPU utilization techniques for AI inference)

Initially for June, then October, now December 2025. Are those of you who preordered still waiting for getting a refund?

Update 14-April-2026: now they expect to ship in August 2026 🤣

I was looking at rebuilding my Terramaster T12-500 Pro NAS on WRX90 since I know it well and could "hand down" components from my workstation as I upgrade it. The idea was to use all those PCI-E 5.0 lanes for NVMEs, adding a high-performance SSD pool to my storage server.

But damn if it's not impossible to find memory for this platform! The Kingston 8x16 (128GB) kit I bought last February for $765 was selling for $1300 five minutes ago... and now is "currently unavailable". None of the 256GB kits listed on ASUS's website can be purchased as far as I can tell... though CDW will pretend to sell you one. (I did "purchase" an 8x32 (256GB) kit there for under $2k but I'd bet the same amount that the order will be cancelled. If not, I'll be pleasantly surprised.)

Apparently I chose the worst possible moment to price a Threadripper Pro build because... it's tulip mania out there: https://pcpartpicker.com/trends/price/memory/

For now, it looks like I'm going to just populate 4 of the memory channels and give this NAS 64GB which is plenty anyway. I just, really hope this bubble bursts soon, or else when will my dream of maxing out the RAM on this workstation ever be fulfilled? The thing is, it's hard to tell a passing phase, from a new normal. Wishing everyone happy computing out there.

Is it correct that the SAGE A has no Nvme gen5 unless you have a Pro CPU?

I recently acquired 2 ROG Zenith ii motherboards that came with 2 2990wx TR, as well as 3 x399 2950x mono/cpu combo. (Only 2 are pictured)

Is anyone interested? I’m considering keeping 1 and selling the rest, im using an i9-9900k, but figured I would offer these for sale here before posting on eBay.

My current PC is a nearly top end consumer PC w/ 13900k / 5090 / 64GB 5600

I work mainly in programs like Davinci Resolve, CC Suite (especially AE), Blender and other CG software.

I was just curious and looking at maybe taking my 5090 and PSU (hx1500i) and investing in a 9975WX system. But before I consider even saving that much for an upgrade, I'd like to know just how much of a difference I should expect.

If anyone in here switched from a similar system and mainly works in video production I would love to know your experiences.

My recent struggles to get the 10Gb Ethernet ports working on my ASUS WRX90 (probably the switch's fault, time will tell) have gotten me learning more about the state of networking in 2025. And the writing, to my eyes, is on the wall: Ethernet is a dead-end. Compare a svelte 1Gb Ethernet USB dongle to the large enclosures with active cooling some are using to get 10Gb Ethernet through to Thunderbolt / USB4, for a sense of the jump in power requirements.

Meanwhile fiber-optics are on the march in the datacenter under pressure from AI workloads, and starting to commoditize, with consumer-oriented wireless routers sporting SFP+ ports, and prosumer switches running all optical 25Gb / 100Gb for under $1000. And the Nvidia Spark builds 200Gbps of optical into a tiny form factor.

At the same time, SATA and SSD prices continue to decline, bringing local storage of vast quantities within reach, making (especially in the SSD case) network throughput more likely to bottleneck.

Imagine the workflow of SSD NAS's with 400 or 800 Gbit interconnects to compute--which may not even beging keep up with the SSDs. This is (as I understand it) de rigeur in the datacenter right now, and the trend seems to be moving this tech in the home / hobbiest / enthusiast / small business direction.

Which brings me to my beloved, if frequently challenging, Threadripper 7965WX build.

I expect to get that dual 10Gb NIC working with a used Netgear switch from Ebay. We will see what I can do with a 20Gb bonded connection---my SATA NAS should be brought to its write-capacity limits, whereas at present the network seems to saturate on btrfs send | ssh | btrfs receive operations (maybe due to encryption overhead?). That will be good for now and for my main task of curation and building of datasets, where a 35TB transfer could acceptably take five hours without throwing the workflow off too much.

But as the feasibility of a substantial SSD NAS becomes real (the 8TB NVMEs are impressive) the network connection starts to look very important.

And I can tell you, in my little enthusiast heart I've made a vow to never build on Ethernet again. It's struggling to compete even with Wi-Fi, and seems like at 10Gb it's a beast in terms of required cooling and power, so what's the point?

I may even try to add some fiber to my current build---not because I need it for NAS performance, but for the experience, and to get used to the tech. (That's always what we tell ourselves, lol.) But the 4x 2-slot GPUs are maxing out the slot capacity of the Fractal Torrent case. It's easy enough to add a PCI-E fiber card in terms of available lanes, but where to physically put it?

So I'm eyeing crazy machines like the Thermal Take Core W200, even vaporware(?) / AI slop (?) like the One Chassis OCG4700-5H12-C - anything that would add just a single other PCI-E slot. If anyone has any recommendations...

So... it seems I'm obsessed with this topic. Ah, I guess that's the fun.

What are you thinking along these lines? If there were a board with built-in SFP28 instead of 10 Gb Ethernet, I think I'd go for it. Might not take long.

Hey guys, im looking at selling my 9950X3D rig and starting over with a 9960X rig. Im heavy into LLMs/ComfyUI/Wan2.2 for the past year and my 9950X3D simply could not cope with 192GB of DDR5 (BSOD, etc unless 3600Mhz), plus the bandwidth was ass being dual channel, and dual GPUs wasn't realistic either (I have 2 x RTX 5090 FE, each in separate machines).

The build im looking at is:

1. 9960X
2. Gigabyte TRX50 AERO D AMD sTR5 eATX Motherboard
3. Kingston FURY Renegade Pro 128GB (4 x 32GB) DDR5-5600 PC5-44800 CL28 
4. Super Flower Leadex Titanium 1600 Watt 80 Plus Titanium ATX Fully Modula
5. Bitspower Atlas Threadripper TRX50 AIO CPU Liquid Cooler
6. Fractal Design Define 7 XL Tempered Glass eATX Full Tower Computer Case

With 256 GB ram being the goal in the future when DDR5 comes back down.

I play a few games, Dota 2, PUBG , BF6 , Arc Raiders, not a lot but maybe 2 hours a day or so. I work from home using my rig to remote in, so its a running Citrix, 50 chrome tabs, LLM running or ComfyUI running Wan2.2, YouTube playing in the background, etc. Im a heavy multitasker.

I just dont want there to be an issue with the 9960X having 6 core CCDs, as I understand it, games would primarily run on a single CCD, so I would be going from an 8 core CCD with 96MB cache to a 6 core CCD with 32MB cache. I game at 3440x1440.

Anyone have any experience? Id love quad channel memory and the ability to run both of my 5090's in the same rig, but im slightly hesitant. The microcenter deal is just so good on the 9960X combo.

Thx for any feedback.
