There's a siliconlabs c8051f342 on it, you can find chinese dongles with similar chips really cheap. Maybe i can find one with the same haven't done alot of digging yet. Cracking it open wasn't needed, it has a clear case and fancy LEDs on it, like you would expect from any development tools 
That looks great but a threadripper 2990wx board requires 2 150 watt 8 pins plus a 4 pin of 24 pin power supply 50 watts plus beefy vrms to clock so more realistic is probably 3.4 g and as low voltage you can prime with or switch to half cores 3.8 or 4g 1.35 volts I think.but this is only going to help community as Rome probably will drop in and party will begin. Mine are retail will play with them as soon as I'm off nero.thankyou for your effort hope bios is useful for us.
I got a little update from a reddit user who seems to have found a way to use zenstates with dual CPU setups.
I also did a lot of probing on my USB005 yesterday and read my way into the world of MCUs. I ordered everything i need to build my own version and a chinese dev board with a similar chip for testing. I paid another 30€ for all parts including a debug-adapter/flasher for 8051 chips. A custom version of the usb to i2c tool should be around 15€ if everything works out.

Was looking at a gigabyte single socket board with 2 8 pin power but if I can get the dual supermicro up be cool. I was 7666 with one cpu clocked to all core 3ghz and other on performance boost at 3gh-2.5 all core.this will help for sure.figured it must be an affinity thing.thanks again for digging it up.
Had the same problem like the other modded bios versions had. It posts but has a blackscreen during that process, so i can't access the bios menu. I'm still trying to figure out if it's maybe a problem with my PCiE graphicscard. I have a vga monitor now to test it with the onboard gpu, but i also got a lot of other stuff to do with my VRM watercooling right now.
It's another problem with the modded bios. With a stock bios everything works fine if I do a small edit with ami bcp.
It's a direct chat, can't post it.
2 threads, some deburring+cleaning and it's ready for a test run.
(no I'm not trying to cool the chokes, it was just easier to mill it like that)

Hello
So about multiple CPUs configuration you just need to start AsusZenstates as usual,click on apply in order to apply your custom pstates settings to CPU0.
-Once is done go in task manager,find AsusZsSrv.exe (not AsusZenStates.exe) then click on define affinity.
-After you'll change Group 0 to group 1,check "use all core" and click Ok.
-Now you're able to modify the CPU1 pstates by clicking on apply in AsusZenstates app.
In order to revert to CPU0 just change group 0 and don't forget to check "use all core" in define affinity .
Each time you reboot the computer you'll need to apply this process.
If you get an "access denied" error when you want to change the cpu affinity just kill the process and restart it .
I also contacted supermicro in order to ask for a custom bios but they didn't approve my request unless you pay at least 500 motherboard/BIOS...

I hope everything is clear for you
Thank you
