DUAL 3090 rtx SLI, Dual CPU, 1.5 TB Ram, quiet, compact case

[Frick]

because there isn't a dual epyc/rome workstation with on board sound, and appropriate pcie slots spacing to do the dual 3090
the gigabyte dual epyc/rome board can't do it either
it must be able to function as a workstation and not a rack mount server

External sound card?

Gents.
I use the PC for research, Its my personal PC. My daytime jobs are in administration, medical, nuclear medicine, and IT; however, I'm going to school full time and doing my dissertation on deep learning and NLP NN. The rig pulls double duty. I've had an uber rig since 1998, constantly upgraded. I have also been one of the first to water-cool, 2 way and 4 way SLI, Titan XP SLI (4way). I have kept the passion going and learned a few things along the way. All along every rig pulled double duty. Here are a few of just the early builds. Back then there was a site called "NVNEWS" and 2CPU.com; I used to post there heavily.

Here some early builds. Yes, we had PCs back then.

Push the envelope indeed

Massive thanks for sharing the rigs in the pic above, outstanding

Very unassuming desk space for such a PC .
I'm wondering what it feels like to have that PC blowing hot air at my feet

same thing as a 1kw space heater...

 

[venturi]

same thing as a 1kw space heater...

I have actually never noticed any heat in my workspace, but then again I keep the house at a constant 69-70F. The heat from the back must migrate to the other direction, but its not too tiny a space, so it really wouldn't provide much of an effect.

 

[_UV_]

What is the real purpose of this 30,000$ PC?

Same as it was with personal SGI, SUN or DEC workstation in 90s. Also, prices for "premium" but affordable parts made a circle. Lets say Ryzen 3900+ decent mobo + GTX 3080 + pair of 1TB SSDs will cost you like a decent used car, just like it was around 1990-96 with tech of those days.

I wish I had that much space but I'm on a laptop. The SSD or HD space is very limited, 8tb is enough until SSD prices come down more.

Hi Venturi, I'm a big fan of your builds. Were you able to get SLI working on DX11 games by any chance? I tried a lot of custom profiles but I can not make that work. I sent you an email, thanks!

Amazing the computer power you can cram in a small box these days.

 

[GhostRyder]

So
it has take a few days to perfect. You know..cable management, alignment, SLI profile building, driver selection, and general tweaking.

So the build is:

2x 3090 rtx Founders Edition & SLI bridge
2x 8180M (56/112 cores
1.5 TB ram
Asus c621 Sage Dual socket motherboard
4x Raid Samsung 860 pro (4TB each, 16TB total) data and backups
1x Samsung 860 pro (4TB) data and backups
1x Sabrent 8TB nvme for Apps and Games
1x Sabrent 4TB nvme (OS)
1600W digital power supply
asus PA32UCX-P monitor
Thermaltake P1 micro ATX case (modified..heavily)
MS Windows Data Center 2020 for OS
1x pound of flesh and blood


I already had a lot of custom profiles for my quad SLI rig, so a few edits and I've been able to get SLI to work quite well.

I've moved my 1x 32GB Titan CEO ed and the othre 3x Titans to my wife's pc. Which is also a case mod clone of this machine, because it was my prior build.


So far, ...now that its all buttoned up, it seems quite a decent PC,
It very quiet, almost inaudible at idle, and creepily quite quiet under load..I like that. Provides no audible presence in room.

Temps are nice and cool, under load the cards have yet to get above 67C.
CPU run at about 41C under load, and RAM hovers at 55C under load.
NVME drives run 28C idle and 52C at the end of a full drive copy.

Very interesting build, very cool! I used to be big into SLI/CFX (Previous builds had 3 R9 290X's, 2 HD 6990's, 2 GTX 580's, and some others) but I have fallen out of wanting to do it anymore mostly because game support has dropped and I don't do some of the stuff I used to with them anymore.

May I ask what you do with this build?

 

[Deleted member 50521]

That is like 2 GPU nodes with high RAM config from a HPC cluster right there. Damn nice

 

[Devon68]

So I see many of your previous PC's were water cooled. Any particular reason for going with air cooling this time?

It's a classic... like the Amiga 1000 or the op's computer will be in 10 years.

IMHO
I used to really enjoy overclocking. I'm a dinosaur, in the early days you could make changes to cpu parameters with a conductive pencil mark and changing jumpers on motherboards.
Lately, I've been able to get decent compact builds that run cool without watercooling. Also, I do a lot of tweaking, after its assembled, and the water cooling makes everything a longer and more complicated process. There was a time when cpus were not locked and getting the most out of them was an art. I enjoyed that. However the "unlocked" cpus of modern times are in the same price point of the next chip level above the original unlocked cpu. If I buy the top of the line cpu, I'd use watercooling to go further, but halo cpus are not unlocked. Lastly, overclocking does not yield the relative performance yield in real-time results. Example, folks that overclock the heck out of their video cards to get a high benchmark score - simultaneously the same settings couldn't be used to play 15 hours of gaming without texture flashing, and other issues. A pc should be able to be turned run, and run for 30 days without someone pouring cryogenic liquids on it to get it to work. That stuff is fun just for a dragsters. My pc is my daily driver. So think of it as a practical Lamborghini Urus daily driver, and not a dragster where the engine and tires give their life on the first run.

So I max out the build to provide the most consistent performance and not worry about the liquids, the evaporation, leaks, pump failures, etc.

I can get more performance by enabling sli, dual sockets MBs, ram, drives, and correctly configure the OS to be a tool and not get in the way of what I'm trying to accomplish. Correctly configuring things will often yield better results than a poor configuration and some overclocking.

So Id o like water-cooling/overclocking, but the ROI is not what it used to be I think I was the first person to simultaneously water-cool dual cpus, the chipset, and the GPU at the same time). I actually had to CNC a lot of the blocks. Example, I was the first to water-cool rambus (Rambus would normally run a few degrees over meltdown temperatures).

@venturi , very well done. Again.

 

[phill]

Can't say that, Amiga's are still awesome!!! This build maybe as good as one, but.... It's a bit close to judge for me

@venturi if you ever feel like you'd like to contribute some of that computer power to WCG or FAH for TPU's team, you are definitely more than welcome to join us

 

[owen10578]

I see you have made your uber PC even more uber lol that's a really awesome build! I wish I got a job where I actually need something like this...

 

[terroralpha]

someone is ready for that new AI porn

 

[IbaChiba]

Unreal build, are you able to expense it for business? if so how much of it.

 

[MIRTAZAPINE]

That is one compact beast. Small form factor Pc people would be so proud.

Well, yes. It was more complicated than I had originally thought. But yes. I am going to try and refine the how to and post it.

I really can't expense it for business as this is my personal home pc, but I did expense the other build that is my work workstation.

 

[phanbuey]

i have a softspot for that earlier v1000 tower build, although I do love the size and style of the current.

 

[zenlaserman]

Well, it's a classic example of having to spend money to make money. I'm sure you'll manage to get this rig to pay for itself

Excellent build, and I dig your philosophy. Thanks for sharing your experience!

 

[purecain]

Looks like the OP had a lot of fun with this build. Enjoy!!! I'm still waiting on my 3090 strix oc.
Only another 6months to go. Really though respect, youve had some cool builds through the years.
