until i rebooted. cant get it back to 3600 again. but if I leave it at 2666 its fine and works great. im going to start putting the HDDs and stuff on.... wish me luck

Been following this since it happened. Glad you were able to get it sorted out!

if its still a 20k paperweight, i will take it. i have a massive amount of papers that a 5k paperweight simply wont hold down,

Looks like one of the 8x slots will be downgraded to x4 if the DIMM.2 slot is enabled, check it isn't

NVidia hasn't removed SLI from their drivers. It makes no sense for them to do so as the 3090 supports SLI over NVLink.
What motherboard and CPU do you have? What's more likely is that the motherboard or CPU you have doesn't support x8/x8 on the PCIe slots you have it in, or you haven't set it to that in the BIOS.

You were right. I disabled that and rebooted. Got the little notification that SLI is possible

Linus does this and has multiple videos on the topic. Here's the latest. You can probably track the others down from there.
 
 

while i was working on the layout, I mocked up the table: to get a polish on the epoxy, it took going from 180 grit to 3000 grit (not skipping a step, and going wet at 800), then a 3 stage polisher. it took 16 hours of just sanding to get this done. and I didnt get it right the first time.
 
a cool shot I took through the edge of the table (yes, there are bubbles, mistakes were made):

 
after the polish job:

I think it is this:
Ultra-Low Jitter Clock Generator (microchip.com)
 

I just wanted to put this here, for someone that might be googling for this issue/idea.
 
Asus has 3 motherboards that I have gone through for my 3990x processor:
Asus Prime-Pro
Asus Zenith II Extreme
Asus Zentih II Extreme Alpha
 
On the Asus Prime-Pro board, there is an asterisk on the box saying that on a 3990x it will only run RAM at 2666MHz. If you think you can bump that up at all by overclocking or anything, you are wrong. you are stuck at 2666MHz period. end of story.
 
On the Asus Zenith II Extreme, it does not have that asterisk. As a matter of fact there are some people out there who thinks this board is perfectly fine for the 3990x. Not quite. With my 3990x I bough 256GB DDR4 3200MHz GSkill Trident Neo Ram Modules. I was told that this kit was for the 3990x. I popped them all in, and booted unraid. I did not enable DOCP/XMP
 
Then unraid crashed. after some troubleshooting, I found that the RAM was causing it. So i ran 4 sticks at a time through memtest86 for a few days on a different mobo. 0 errors. I then tried running all 8 sticks through memtest on the zenith II Extreme and I noticed that only 192GB showed up. ok, I have a couple sticks that werent seated or something. I then rearranged as many ways as I could to rule it out and it always came back to 192 GB. I then tried to boot with just 4 sticks and it worked perfectly at 2666MHz.
 
on a side note, enabling DOCP caused the mobo to keep rebooting until it went into safe mode. Didnt matter how many sticks I had. 
 
Now I am on the Alpha. it shows 256GB RAM @3200MHz. no issues at all.
 
So, if you have a 3990x and want an ASUS board, get the Alpha.

That cable has the same connector on the other side and was connected to the main backplane. 
 
I pulled everything out and put it up on a test bench to do more troubleshooting. As soon as i hooked it up, it saw all hard drives. I guess someone sprinkled FM dust on it to make it work....

Ordered. Thank you.

final assembly:

went round and round about the layout. knowing that I am going to create some heat, I have a ton of hard drives, and I have 2 complete PCs (one is a server). I will skip past it an show you the final layout

there is a cutout underneath this with a filter in place so as the fans push down it forces air through the hdds to keep them cool.

as that cured, I started working on the leg. Not a whole lot to it, just welded them up, grind it down, and send it off to
 
after grinding this is what it looked like:

Ever since I saw the desk PC that Linus did, I wanted to create one too. One big difference is that I did not want to use MDF as I personally think it looks cheap,  and not very sturdy as a table top. Linus had a piece of glass over his and that served him well. I did not want my forearms on glass anymore and I love the feel of natural wood over glass or acrylic. I also have been dying to be able to do an epoxy/live edge table. So i thought if I can do a river table with clear epoxy in it and put a shelf underneath, it would look real cool. so I started designing.
 
I needed a larger desk than normal as I have a lot of different projects that I work on, and some are physical, so I started with 70 x 40 (all measurements are freedom units  ) table top. I wanted minimalist but sturdy legs so I decided to go with 4x1 square 1/8in steel. Doing some math, that left me with a shelf of 58 x 25 x 8 to put all the computer parts in.
 
so starts the build...
First I looked for a slab that wasnt too expensive, and fit my dimensions. after running through a planer we got a very worn and ugly piece to look like this:
 
 
We decided where to make the cut. Normally on live edge slabs, you cut it long ways then flip it so the live edge in in the center. I cleaned off the rot and bark:

 
we then set up a mold and an area that was free from dust:
 
then the pour started:

 
it took 3 different pours and 10 days to fully cure. 

set everything to the specs on that page and ran a short 10min stress test:

 
half way through this, I noticed that my 2080 ti was running full bore. it is in the same loop just before the CPU. I like these numbers way better. I turned the GPU off and it had no effect on the temps.

during all this time, I created the box that the computers would sit in. this, by far, took the most amount of time. First thing to do was to mock up what it would look like under the desk:

 
then the glue ups (we have dominoes in the joints for added support):
 
then sanding down to 320 grit and finishing (in this pic, you can see the layout starting to take shape):

people said they run hot, due to my cooling design I might have to make some modifications: is this too hot?
