miniITX GOD Box....Blasphemy!

Thanks for the explanation! Did you buy them on ebay, through the forum, or elsewhere?

How did the retail 8180M and 8176M perform in comparison? I assume the ES did not work on your board.

What affected RAM performance? More than just frequency?

It sounds like your build is around $4600+RAM(~$3200?)+SSD's(a lot)+GPU's(many a lots).

Yes, the 8180m were bought / negotiated on eBay
Despite trying several motherboard microcode hacks, I could not get the ES / B0 stepping to work on the asus Sage. However the 8180M QS chips worked flawlessly and consistently gave 200-300 (as a pair) more points in cinebench and better scores in other benchmarks when compared to the retail 8180m chips. So I kept those, returned the retail and all the ES chips.

Ram performance: the Samsung ram just performed better than the hynix and micron. It was also cheaper

This is kind of an evolution of your 2016 build, eh?

Talk to me about mounting the back panel for the GPUs, and cutting slots for the bracket tabs into the case motherboard tray?

Also, how did you mount the PSU on the back?

The SSDs are just screwed into the grill, right?

Also assuming you drilled/tapped a few holes for additional motherboard stand-offs?

Took an 8 slot bracket from a Thermaltake P5 case and measured and screwed it in with Allen screws to the case. I also drilled and Dremmelled every card tab hole into the case side. The PSU is mounted to a steel plate that is also screwed into 4 faces of the case to give rigidity.

I made CNC aluminum plate with mounting holes for all the SSDs. It is mounted to the inner wall of the front of the case. There is no grill. That was cut out to let the SSDs protrude.

I drilled and tapped the additional stand offs for the MB. I also drilled and grommeted the surrounding cable holes

Happy to report that ray Tracing is alive and well in Metro Exodus with my titan Vs

What are you using this rig for? I think I've asked that quetsion before : )

I'm really surprised how good this case looks with EATX Dual CPU Mobo. I got Z10PE-D16-WS and now I'm thinking... .

 

[Venturi]

I use it for fun and games whenever I don’t do school work or bring work home with me.

Isotopes, nuc med, medical imaging, deep learning algorithms (ann cnn), email, papers, spreadsheets, porn surfing on this site...etc

Dang !!!

I have the same MB here, 4x Titan V's gave me some tasty ideas !

Small update

I moved to LRDIMM so the pc now has 768GB of ram

 

[nofearek9]

50 years later....ram minimum requirements : 512gb

I can't wait till we have photon based chips instead of the silicon ones we have now

maybe we will have positronic computers (alla Star Trek data)

I wanted to use the noctua NH-D9 DX-3647 with larger radiator and 120mm fans instead of the 92mm fan noctua units I had.

The NH-D9 DX-3647 extends 1.7cm into thew area occupied by the first video card (I use 4 video cards so I need all slots) There are two sockets on this motherboard (dual cpu) so it requires two NH-D9 DX-3647, so both extend 1.7cm into the space occupied by the first titan V. I need and cannot live without all 4 cards before anyone suggests the video card extractor tool.

After extensive work in augmented reality I was able to do this:






...now, if only noctua fans were not so ugly...

and remember the whole case is only 16 in x 15 in... (417mm x 372mm)

 

[Peanuthead]

The Noctua Redux fans are black and gray.

The Noctua Redux fans are black and gray.

I did not realize that particular model fan was available I black and gray but kept all the same features

 

[nofearek9]

temp dropped?
this is much better setup .even if the radiators had the same size ,the air flow will get you better results.

 

[Venturi]

Cpu temps were low already. With new set up the temp dropped about 5 Co the front cpu but only 2 C on the back cpu due to it getting pre warmed air from the first cpu. Before hand they would level out equal under load - but yes an improvement

The real winner was the ram, which is why I did it to begin with. The LRDIMM 64GB (x12) runs much hotter than the 32GB dimms. With the new configuration the ram dropped 12 C landing about 2C lower than the original dimms



I would have done this sooner, but was not motivated till I got the new ram. The new heatsinks out of the box extended 1.7cm with fan into the video card space

 

[gigatexal]

What about a ram fan? I’ve seen some that hook into the dimm slots and just has a few 40mm fans that blow air directly on the dimms

 

[nofearek9]

or aluminum heatsinks

thanks, I did consider it.

Ram fan conundrum:

A. I like silent and those fans sound like turbines
B. They won’t fit due to proximity of video card slot, I tried a few

I did buy pure copper heatspreaders and 10 packs of the pad minus 8 thermal grizzly.

I don’t like using the included two sided tape because if you reseat it or try to take it off Theresa good chance you’ll just rip chips right off the ram pcb.

And, the tape is not very thermally conductive.

The minus 8 Pad 1mm and very heat conductive and electrically inert. And isn’t sticky.

At 1mm it’s two thick tours on the heat spreaders, so i’m going to run it through a lasagna press and squish it down to .5mm (and doubling the area it would cover. Then it should be a solution.

 

[Venturi]

LRDIMM best heat spreader design I can come up with :


So here is the process I went through to use pure copper heatsinks, no adhesive, and thermal ceramic clay.

6 of these:



wax paper and ceramic clay



lasagna press to reduce 1mm to .5mm and gain more area.








View attachment 11094


and here is the final outcome







Dimm Temps
medium low use / idle temps / checking mail / being on this forum temps:

about 42 C average across 12 LRDIMMs


and this concludes the experiment. some observations:

under load the LRDIMMS still get warm / hot but 13C less than before.

after a workout, the dimm temps stay higher longer due to the amount of mass / heat retention added by the ceramic clay and the copper sandwich.

seems to be an improvement overall.
