help with gigabyte MZ73-lm0 motherboard and genoa-x 2x 9684x help

[Venturi]

ok, Corsair changed that default later. but worth to mention thought.

It is indeed, the older software (not the bloatware iCUE) makes it easy to manage. Also "SIV" can manage the ax1600i without having to install any software. The 2050w is by default built as single rail, negating that background thought the corsair can poke at you.

Additionally, for 2050w one needs to plug it into a 240v or it will only do 1650w on 120v. I have mine in the 240v socket.

UPDATE

I have received a new Bios (F30) and new BMC software. In combination, the dual 9684x are recognized and behave as expected (or as hoped).

There a few minor issues on the F30 bios but, all are manageable.
Gigabyte also added in the resizable bar I had requested.

so, progress

nothing to write home about but here it is running fast, cool and quiet:

looks like ASRock (Rack) BIOS stuff LOL.
have got a new CPLD Firmware ?

Hi, I didn't look to see if the CPLD firmware had changed, I'll have to go look through old screenshots and compare

normaly you get a file for each, BIOS,BMC,CPLD

So far, I have only received the F30 Bios and the new BMC firmware

ok thanks, could have been...

 

[Venturi]

thank you for ALL the help. Its been an official month since I got it going with the collaborative F30 bios and the new BMC.

I also cloned the unit for my CNN and RCNN endeavor, and K space reconstruction in MRI and SNR.

The home PC is normally my protype platform

build... more or less complete:

Just wanted to say thank you.

I've learned a lot along the way so if any one needs help on

dual 7773x and MZ72-HB0

or

dual 9684x and MZ73-LM0

please ask

finished about 5 weeks ago, it runs cool and quiet, even under full load its a pleasant fan sound, but definitly not loud. At idle, you would not find it if you were blindfolded in the room.

had to edit/change the heatsinks to be better, a lot of bending, cutting, and modifying

those coolers are on revision 4, going on 5 and work well, especially with some of the threaded algorithms I use, hammered at all core the temps have been manageable and no issues. Don’t let the outside fool you. The base plate of the heatsinks is now all copper, nickel clad frame, the fins have been individually placed on the heat-pipes, pasted, and been mindful of full contact. and has increased in thickness to 5mm, the the 6 heat pipes are pressure grabbed and have Metal based TIM in the micro gap areas to improve contact, the fans can spool from 450 to 3050rpm, the BMC fan curve has then at 100% at 75C, but according to the BMC logs that has yet to ever occur even under an all core load.

Here is the fin protype and base that is going on next. I have increased fin density as well:

The dan gigabit chip / heat-sink is like a live waffle iron


so had to move to home made all copper

before final cleanup up and deburring




slight acid pre-dip to increase porosity and surface area (not just from 5x more fins in copper) and then
need to color match of course, so this works on copper :



was clear in color, reaction taking place:


final product, new gigabit chip heatsink, 30x more surface area:



The result , from using another TIM, moving to copper, increasing fins and surface area:
now 52C (down from 90C),

mission accomplished

 

[Venturi]

final result, of better TIM, better fans, bettering the CPU heatsinks, better video card placement (the 4090s are upside down and blow warm air away from CPUs and motherboard) and even the gigabit chip cooler:


room at 71-72F

....some of us hardcore folks may find this collaboration BIOS version (F30) very interesting:

So next on the to do list is to replace the other cheesy lightweight short small heatsinks for the Mosfet / voltage regulators etc that came with the board. This time I was able to find them halfway across the globe and specific to this board:

 

[Venturi]

so I added the upgraded heatsinks, overall result nothing too spectacular, those components are running 7-12C cooler, so I think it was worth the effort:



combined with the edited/improved cpu coolers, the cpu heatsinks have a a full copper plate to completely cover the supersized 9684x's footprint

The copper plate is 5mm thick

heatpipes and fin adhesion was improved

more fins were added to the full 120mm

combine with 350-3000 rpm phanteks t30

and outcome (quiet silent and cool running, even under load its not obtrusive)

 

[RolloZ170]

overall result nothing too spectacular, those components are running 7-12C cooler,

what most people don't know: the power stages are soldered on the PCB and dissipate more heat to it than the top.

True, indeed

but the additional (rated 16) thermal pads and that much conductive metal, did drop temps significantly enough (depending on which ones 7-12C) compared to factory heatsinks. The greatest drop was the center set which was consistently a 12 C drop. Now everything is running at less than body temperature

this is server board. server chassis FANs blow strong airflow over and UNDER the PCB. Big Heatsinks will disturb the airflow.
if you put the board in a WS case you have no other chance than what you have done.

 

[Venturi]

this is true, and for the record, the back of the board is exposed to a skeletonized area that has internally 2 fans and 2 blower fans moving the air, even the drives have extake fans, all low rpm and quiet/silent, but keeping everything serene
