Any advice on tuning this board for power efficiency? What the best idle power usage people are seeing?

A timely question! If you look back through this thread, this is a very power-efficient board in general. I've been running it with a 5700x, but recently switched to a 5750G APU. The APUs are monolithic die (instead of chiplets) and also PCIe gen3 (instead of gen4), and generally have lower idle power consumption versus their non-iGPU counterparts (likely at the cost of some top-end performance).

My system:
  • Seasonic Focus SGX-500 SFX-L
  • 128 GB ECC RAM (Crucial MTA18ASF4G72AZ-3G2R)
  • 2x SATA SSD, 4x 14TB HDD, 1x NVME
  • TrueNAS 24.10 Electric Eel
  • TrendNet SFP+ 10gbe NIC (AQC100)
  • Two Arctic P8 PWM PST CO fans and two Arctic S8038-7k fans at about 2k RPM
  • Thermalright TL-9015R fan (on CPU heatsink) at about 1500 RPM
  • Coral USB AI accelerator

This is a fairly idle home server. I am running Frigate NVR, which keeps the system lightly loaded.

Using a cheap at-the-wall AC power meter (similar to a Kill-a-Watt), I measured about 71 watts with the 5700x.

Since switching to the 5750G, for the last week, I'm at about 62 watts.

I'm also monitoring the total power draw of this server plus other stuff that is connected to my UPS in Prometheus. Looking at the data in Grafana, I also see a roughly 10 watt drop in total power consumption after switching to the 5750G.

That is actually more power savings than I expected. I think it's partly due to the power efficiency of the silicon itself, but also due to the fact that I can now use the iGPU for more efficient, accelerated decoding of ffmpeg that Frigate uses (previously that was done only in CPU via the 5700x).

Note this is without any meaningful BIOS tweaking. My next step is to put the CPU into a lower power mode via the PBO settings.

Hello
So i have installed a Ryzen 5 Pro 3350G, one stick of RAM in A1 slot and the power source connected.
I have successfully updated the firmware to 12.61.21.
When i try to update de BIOS (currently at F06) i get failed due to update fail.
Also the CPU fan and the power source one doesn't spin at all.
What am i doing wrong?

Wow! Talk about price fluctuation. I looked at this in the beginning of the week and they were €55 each incl cooler from Piospartslap. Today when I finally decided to make an order of two they’d more than doubled the price to €127 each.. I made a price suggestion for €55 and commented that I’d like to buy it for their cheaper earlier price.
It got rejected, oh well..

Then today they’re back at the same low €55 price again.. ‍o_O

Edit: Nope, must’ve been a cached site that showed €55. If I refreshed it went up to €127 again… :confused:

whew just ordered two more for lowly price, in the nick of time, it seems, came last week..

But I'm having some trouble, video output stops after a short while. Sometimes in a few minutes after a boot, and sometimes ten minutes. Happens even in staying in BIOS menu. It's also lost in the BMC H5viewer. I've tried a lot of different things, take pcie cards off, different ram sticks, reconnect psu, checked case power button cables etc. It's a weird thing, as cant thing of much what to try out other than take everything everything apart. Can't think of much, could an empty CR2032 cause this? Only thing in log is
"ID: 7 Unknown sensor of type system_event logged a bios : Timestamp Clock Synch was asserted"

edit: 5600x with 64gb ram

BMC chip overheating ?

just replace batt. and....

yeah I finally got around to replacing it now.. let's see.

Has the BMC overheating been a thing with this? Never heard of it on any machine before.. :oops:

happens every time upon boot, I think. This machine's been under work for a while, I set it already once up and then was carrying it to the rack where it started show symptoms.. maybe I should take a look at updating the bios+bmc software, too. Bios says "To be filled by O.E.M." under project name :D

just a guess because the VGA unit is in the AST2500 BMC chip.
this is not a workstation- it is a serer motherboard, need continous little airflow.

Hello again
I have installed a 3300X CPU
The fans don't spin and i get the same error when i try to update the BIOS
What could be now?

check manual please(RTFM)

Wait i need to connect if to a case and turn it on from there. The case hasn't arrived yet.
I thought that with IPMI you could turn it on just with that.
I need to wait for it to arrive and then check again.
