Your the only one using as much hardware in there system as me and you have no issues yet im struggling …i gotta figure this out…

hi, Devinkb, thank you for your information, could you please provide me with more detailed information on this cooling solution?

The AI stuff I’m doing is mostly hobbyist understanding of all AI modalities and model training for each - code, voice, video, text, image, music generation. Just trying to stay on top of my developer game. CAD stuff is for car projects and 3d printing. I built and programmed a digital gauge cluster in my car and built the top air intake portion of my car’s engine in a 3D printed high-heat and chemical-resistant thermo plastic. Also designed and built a large 3d printer.

I have the same issue with 2 different asus wrx90 boards and 2 seperate processors. I now have a new powrer grid…all gpus and everything are fresh and new. Why is this happening …

My power situation is 1000% better now…its so crazy…we had a 12 bracker box with 20 amps breakers plugged into wires rated only for 15 amps. Scary stuff. Thats all behind us now.

This at least happens to have a matching driver version as the RTX 6000s and lets both cards run well. Some of the other driver versions for either the RTX 6000s or the 4090s are not compatible between both.

The rest of the fittings and solid tubing was from bitspower. I am in the US and highly recommend purchasing through their Taiwan online shop. Their shipping and response time was way faster than purchasing through the US storefront.

Here is the display driver I’m using that is working for both the 4090s and the RTX 6000 ADAs: GeForce Game Ready Driver | 551.52 | Windows 10 64-bit, Windows 11 | NVIDIA

The embody chair is good. At first purchase you realize that no matter how much money you spend on a chair, it’s still just a chair. You also realize that you can have bad posture no matter what chair you sit in, so just because you buy a nice chair doesn’t mean you suddenly sit up straighter. I do like it though. It does feel comfortable. I’ve had this chair for 13 years now, and it still feels nearly brand new, so I think its durability is the feature that most impresses me.

To be honest, I haven’t run it at full load yet. The AI stuff I’ve done on it so far doesn’t stress the GPUs all the way, and I’ve been spending so much time reinstalling windows and trying to figure out other build-related gotchas (like SSD write speed issues with multiple monitors hooked up, see my other thread, also mostly resolved now) that I just haven’t had time to put it fully to use. Also, the multi-gpu benchmarks I was running in cinebench happen so fast that the GPUs barely spin all the way up before the test is over.

On the power side, I have a 30A 240V outlet, plugged into a 240V 5000W Eaton UPS, which then feeds pure sine wave power to 3 Seasonic 1600W PSUs. So the power should be exceptionally clean in that regard. I’ve noticed you have a lot of hardware in your office from the video you posted. Have you checked your AC power voltage? The more power you draw the lower the voltage sags. If you sag too low it can shut off your computer (just trying to think of ideas of things that have happened to me in the past).

The waterblocks for the 4090s were some rack style blocks from ekwb that were only compatible with the zotac 4090s. It got it down to a single slot. Most 4090 waterblocks are dual slot.

As far as my computer is concerned i am still restarting…i really don’t get it. The computer is defintely performing better. I am getting about a 40-60% frame increase in any game i run just to test 3d excelleration and it just generally feels better.

So just with the CPU and GPUs I’m pushing 2900 watts, which is awfully close to the max of two 1600W PSUs. The third PSU gives me some room. I would have done two PSUs if some of the PSUs announced at CES this year were released already (There was one PSU that had 4 12VHPWR outputs for example).

Heat will be no problem for the computer with the giant radiator and 18 fans on it, but yes, office will be a little bit warmer (it’s a big office).

In short, a single BIOS change to Disable USB4 enabled my ASUS WRX90e to POST with more than 4 GPUs and it boots fine into Ubuntu Server and nvidia-smi reports all GPUs as expected.

Other than that, it’s pretty standard setup other than it not automatically detecting and activating my displays. I’m just running Windows 11 Pro on it.

The issues that I was having was just getting it to recognize hardware and turn on. But no instability while it’s running (except for the physically unplugging and replugging displays).

This post saved my sanity! Thank you to original poster and all contributors for crisp thinking and explanation on this topic.

I hope ASUS updates the BIOS to handle this better (current is 0404), either by fixing USB4 resources or providing an alert or error message.

I am currently running my studio out of my childhood home and the power setup was abysmal. We just did a pretty substatial upgrade today actually that was spurred on by all of my computer troubles.

Glad that my post was helpful! And glad to hear that your power situation is improving. Hopefully that fixes your issues.

Here are some photos! Eventually I’ll post a video - I recorded the build process, GPU teardowns, etc. IMG_16271920×2560 500 KB IMG_16241920×1440 418 KB IMG_16251920×1440 311 KB

We need to rewire some things in the home but the studio power is now as isolated as it can be without me spending another arm and leg. The main thing was to make this space workable and stable and most importantly SAFE , until i get my own place.

Regarding your PC issues… I don’t know. If it were me, I’d start removing one piece at a time until it stops happening, and then start adding one piece at a time until it starts happening again. It sounds like it could be anything from power, bad hard drive, bad memory, bad video card memory, or motherboard i/o related. Definitely seems like something weird with your combo of parts, and maybe a BIOS update will fix it. I check for a BIOS update everyday (as I’m sure you do, too).

I can’t think of anything else that’s out of the ordinary on my end worth noting. I hope you can figure it out! Will check out your other threads and see if I can offer anything else potentially useful.

Though I will say that upon my very first startup of the machine with just a single 4090 in it and one monitor connected via displayport, I couldn’t get it to bios - nothing would display on screen. I eventually grabbed a 3090 and used an HDMI cable, and it finally POSTed and I was able to get into BIOS. I’m not sure what was going on - if it was the video card, the cable, HDMI vs. Displayport, etc… but that’s what I did on my very first startup. After that it started posting normally with just the 4090. At this point I hadn’t started doing any sort of dance for the computer gods to get things working. That came much later

New electrical box , and i have 2 dedicated 120V 20A lines ran to my studio space of which the computer has claim to one and all the other devices have claim to the other. We will see if this helps things. The power in this house…my goodness i cannot stress enough how poor it was.

The distribution center behind the rubber hoses is fairly complicated and required two alphacool distro plates. It travels through the CPU first, then the memory, then all four RTX6000s in parallel, then the 2 4090s in series, and then back out of the case to the radiator. Since I wanted to do a mix of hard and soft tubing, it made the setup pretty complicated (and expensive).

Hey Lailai - sorry for the delay. Haven’t been hanging out here as much lately. Here’s the information on the watercooling setup:

With the dual water pumps on max, I push about 2.6liters per minute through the system even though it has to travel through quite a bit of equipment. The memory and video cards never get above 50 C under full load that I’ve seen so far. The CPU at 800W can still hit the thermal throttling point eventually even with the fans on full blast. (I have an all core 5GHZ overclock).
