Asus PA32UCG-K monitor, TT SFF case, MS Data Center 2022 & Ubuntu
 
The build:
CPU run at about 41C under load, and RAM hovers at 55C under load.
NVME drives run 28C idle and 49C at the end of a full drive copy.
 
I'm using 1.5TB of ram, LRDIMMS
upgraded to 2x intel Xeon 8280L processors, the L have higher memory management
Dual 4090 RTX FE
The motherboard is revision 2.1x
Bios 9904 with Resizable Bar
C drive is a Sabrent TLC Rocket 4 plus 8TB
D drive is 4 Micron 9300 Max 12.8TB each (51.2 TB volume) using the U.2 connectors - Using VROC premium key
I have built in (hidden in the case) backup of 4x Samsung 860pro 4TB, as well as a network backup to a NAS in the house
Using VROC premium key, direct raid control and paths - please see pics of the WRITE speed of the internal array

Running MS Data Center 2022 as the OS and Ubuntu
 
To make it all work and have that in place it took a complete redesign just to have it look similar to what I had before but a lot of base design was changed.
The dual 4090 FE RTXs sit several centimeters above the board compared to where cards normally rest. This required changing all the mounting points and supports for the cards. The video cards needed a custom bracket to hold them stable as they are several centimeters above the board.
This allowed for 4x u.2 connections for the micron 9300 nvme drives in raid to fit to the board 4x u.2 plugs

The C drive now has a large pure copper heatsink on it as well, under load it only reaches 40C, idle is 26C.

The 4090 FE RTXs also operate about 29C in idle. Under load they really don't go past 51C (so far)
ever, most game play hover around 41-47C, application DL/ML may run the cards at max around 51C.
 
The decrease in temperature is from the additional air channel between the video cards (3.3Cm) and the motherboard. Other temp decreases were inn the CPU, Ram and chipset.

Machine runs very quietly.
Most fans ( including the GPUs) turn off at stable temps (auto settings from motherboard control other fans. CPUs at idle run about 23C (73F) in a 21C house (69-70). Under load they may reach as high as 44C, but not often.
To accommodate the 12.8 TB each 9300 nvme drives, I had to install two cooling fans internally to the design so as to have a quiet airflow over the 4 drives. (see pics) This keeps the 51.2 TB nvme drives drives at around 39-41C under load and 33C at idle. The fans are quiet and invisible to the outside but I will also include a picture of that design.

There is a picture of a Macrium backup report showing the READ speed of the C drive (Sabrent rocket 4 plus) to WRITE the backup to the NVME raid (Micron 9300 4x) at 50.6 Gb/s

PC runs very silently, nice and cool, on average components under load are basically at body temp (feels organic when described as such).
I hope this answers core questions here is a benchmark post to show some of the capability -still first on leaderboard

Sick rig. Does auti diff SLi allow dx12 games to work in sli?

yes.... but there's a lot of pain

+1 awesome rig
 
Pretty sure the enclosure is for your NVME drives right?  do you mind providing a link to that NVME enclosure?  Very cool

That's a BEAST!

Lets see some cyberpunk 2077 benchmark numbers then with everything maxed out without dlss. 😁

Sir… you wound me. I would never use DLSS.  
But I will post some maxed out cyberpunk scores when I get home

Lets see some cyberpunk 2077 benchmark numbers then with everything maxed out without dlss. 😁

First, I never use DLSS.
 
Second, I did optimize the setup, config, and system, but there was nothing I could really do to get near 60 fps with max settings.
RTX psycho setting is just over the top tough and not viable.
 
So here are 2 runs at 3840x2160:
1st run set on medium RTX, second run set on psycho RTX
 
Max eye candy except: no motion blur, no vignetting, no DLSS, no dynamic scaling, no chromatic aberration, no film grain, no depth of field, no to anything that lessens visuals
Psycho setting whenever possible:
 
first run, here are screenshots of the settings:
 



Result 1

 
 
 
2nd run, upping the RTX to psycho has a huge impact:
 

Result 2:

 
 
so obviously, I'm not going to use RTX psycho setting, and stick with medium
 
Honestly I was disappointed, I really thought I could get past 60 fps, going to quietly admit defeat.
 

hi, what is "ssr"?

Screen space reflections

sir, screen space reflections was on and set to psycho, see above post picture ^

I was just answering what SSR was, I didn't ask you to do anything.  Sajin asked you to put SSR on Ultra.

my apologize sir, I was back on my phone and thought I was replying to same user, no disrespect was meant.

Yes, could you please rerun the bench with ssr on ultra, and raytracing on ultra? Thanks.

Oh, wow. Ok. Thanks for posting your results.

Sure, same settings as JayVenturi. But only 1 4090

P.S. Sajin, saw you @ #15 on the Time Spy Hall of Fame .  Good going .

Thanks.

Hey Jay how is the build going, any new changes yet? Or were you able to optimize it a bit more?

Awesome! I am so glad I do not need that level of insanity anymore haha. 

Yeah CP 2077 is the new crysis, its why I won't go over 3440x1440. I like staying at around 70+ FPS on average with DLAA, RT OD"Path Tracing", FG, and everything else cranked up to Psycho/Max-Ultra.
