Thanks for the link.  Looks like ASRock knocked it out of the park again.

 

Mother nature intervened over the weekend with a fair bit of snow, and I was without power (except for the essentials on the generator) for a few days.  Hoping to get the new system up and running over the next couple of days.

Hey @J7SC_Orionwhat motherboard do you have?

 

I still have the 2nd CCD boosting problem, I am wondering if a new board would fix it, I also might be able to run 8000mhz RAM instead of 7600.

 

If the fiancee agrees to it.. lol. And thanks.

Not sure if I'll make a thread, but heatsinks are prepped and installed for watercooling the memory on  my new workstation/daily rig. 

 

 

Nothing spectacular on the RAM yet, due to the subpar Micron IC's and the temp issues I was running into.  Current RAM clocks below.  Overall speed/throughput is not bad so far, considering I only spent $700 for 192GB.  Just working on tuning primary timings down from the JEDEC 6000 I started at as a baseline.  Running at 6200mclk/2067fclk, which is where I hope to stay, after I get all the primaries and secondaries tuned down to their fastest stable timings.   CMD rate is at 1T, need to tweak the script a bit more to parse out the correct CMD rate. 

 

      

A few pics on the bench, which is in a state of disarray.  Too many projects and too little time.
Currently everything on the bench is on air, so I won't really be able to dial everything in to max clocks until it goes under water.  Running CPU at board/platform max PBO+CO for testing, but ultimately it will be running at a static OC.  PBO+CO overclock would leave some performance on the table. due to the artificial max boost limit.  CPU is always at >50% load, so a static OC will give the best overall performance.

Hey you two, can you help me out here? I have a 9950x now and it runs my memory at 7600MHZ just fine, but I am aiming for 8000MHz.

 

It made it almost all the way through the test and then I got this with no errors afterward:

 

 

 

That was the only error. What should I do? Raise voltage or a particular timing? I did have the flag --max_errors 1 but it kept going. Is this something minor that is safe to ignore, or should I not run my system at 8000MHz ram? (Orion, I am still using your timings and running the sticks at 1.435v)

Never posted the final specs/pics of my updated ThreadRipper workstation.

 

2600W in 44L is fun.  Pulls about 2200-2300W with CPU and GPUs running all out.

 

Case: Lian Li 011 AIR MINI

CPU: AMD Threadripper 7960X

Memory: 192GB Micron DDR5-5600 RDIMM @ 6200 MHz

GPUs: Asrock AQUA 7900xtx, 2x Radeon VII

Drives: 2x Samsung 990 Pro 4TB (OS), Seagate FireCuda 530 2TB (misc data and VMs/containers), 2x Micron 5200 PRO 3840GB (backup), SanDisk Extreme Pro 480GB (zram backing device) 

PSUs: Super Flower Leadex Titanium 1600W, EVGA SuperNova G3 1000W

Cooling: MO-RA IV 600

Damn, that's a beast. Where are you passing through the tube for the MORA?

[tictoc]

Tubes for the MORA go through the second PCIe slot below the top GPU.

I *love* that you crammed three water cooled GPUs and a Threadripper into such a tiny case! It looks awesome and it must perform awesome too.

 

What are the Radeon VIIs for? Do you fold on this machine or something?

 

EDIT: the copper and black theme reminds me of Steampunk or something. Nice choice in using what looks like matte black tubing instead of clear with a color or shiny black.

Right now the Radeon VIIs are just running a BOINC project (Einstein@Home), but their primary purpose is running some physics simulations and also serving as test devices for building and running the latest ROCm stack.  I will be pulling one of the Radeon VIIs shortly and swapping it out for a 9070XT.

 

The matte black tubing is 10mm/16mm EPDM, and in addition to being better suited to 24/7 operation, it has the added benefit of being able to turn a tight radius without kinking.
