EPYC 7003 Single Socket 16DIMMS

[Harmony]

Currently using H11SSW-NT the obvious choice is H12SSFF-AN6 but they are too expensive.

I've come across ASUS KNPA-U16 SP3 but the reviews don't seem to be too good, they seem just a bit too cheap to me for some reason . I don't need all the NVMe via SlimSAS ports the Supermicro have what other good options are there?

Gigabyte mentioned a way (BMCwebGUI and RBU file) to flash rev. 1.0 to rev. 3.0

If you read reviews on Geizhals this upgrade might not be easy to perform and can lead to some problems

3 reviews....
the problems mentioned also existed before the update. You should be able to flash the BIOS with the BMCwebGUI, the BMC with socflash is more difficult, but you always have that, not only when upgrading to 3.0

Where is this guide? Also how do these perform with Supermicro no BMC issues like with ASRock?

if you have the MZ32 and the serial, contact Gigabyte support, download the tools form they're FTP server and follow the instructions.
gigabyte knows what to do thought.

don't, its gigabyte not supermicro.

don't, its gigabyte not supermicro.

Confused with this, the motherboard works OK in a Supermicro 825/826 for example? All sensor readings.

supermicro chassis supports supermicro motherboards only.

supermicro chassis supports supermicro motherboards only.

There are adapters to connect the Supermicro front panel althrough i have never used then and dont know the specifics
If you have PMbus capable PSU you can readings from power supply
Is there any feature you would miss if you would used non-supermicro mobo in SM chassis?

to be correct: supermicro uses SMBus

I was under impression PMBus is standard since not just Supermicro makes PSU with it

 

[RolloZ170]

sure. supermicro mboard will work with SM-PSU PMBus.
but if you have issues and ask supermicro they will say
"supermicro chassis supports supermicro motherboards only."

which PMBus version ?
its possible Asrock and or Gigabyte does the fault (i do not say they do)

sorry. I didn't know what chassis you have. and not you want to keep.
why for example ?
have you Supermicro 825/826 ???

I am open to other chassis that support ASRock Rack X570D4U and Gigabyte MZ32. I got Supermicro as I normally use Supermicro motherboards + they are cheap and always available on Ebay.

Please make some suggestions

 

[rtech]

I have found Asrock support matrix maybe it will help
You could also contact Gigabyte support

you can try with your supermicro PSU first:
maybe gigabyte is more compatible, but read this
