There's also the Radxa Rock 5 series. I previously looked into this (about 6 months ago), and the ITX version was on the pricey side, and upstreaming linux kernel support was a work in progress.

If the server supports acpi and uefi it should be relatively simple to get anything booted, as long as drivers are upstreamed. If not, the server's devicetree needs to be added to the kernel and you'll need to figure out how to get the bootloader going. It's more work to upstream, but it...

Ahh interesting.. so the 8000 series has integrated IO vs IOD for 7000/9000 series. Ok that could explain quite a bit...

With 'IO die on non-G CPUs' I am guessing you mean to say that the 8600G only has 16 PCIe lanes exposed vs 24 for non-G regular desktop CPUs. If not, please be more specific. While these additional 8 PCIe lanes are not exposed, they are used to drive the onboard graphics which is a much larger...

The Asrock rack Am5d4id doesn't have a chipset and works fine for PCIe and Ryzen 9000 CPUs.

Here some first-hand experience: * Xeon-D (at least Ice Lake) has a relatively high idle power consumption (at least my 4C x12sdv does) * On the AMD side, my 7950X has much higher idle draw than my 8600G. Maybe it's due to the infinity fabric of the multi-chiplet design, maybe the 8600G is using...

Trim or over provisioning - the need to run the various housekeeping tasks remains. The question is how the drive's deep sleep prevents/affects this exactly. I'd love a ssd firmware engineer to chime in on this perceived issue, to confirm it or to put it to rest...

My understanding is the reverse - the garbage collection is only really effective with trim, as the drive doesn't know otherwise which blocks have become freed up by the operating system. Once this is known (by issuing TRIM), the drive can run housekeeping tasks to move data to these freed up...

You'd be surprised then. Here's one manufacturer telling you not to let the drive enter deep sleep modes for this exact reason: My SSD Used To Be So Much Faster But Has Recently Slowed Down ... What Happened? I bet other drives work similarly.

The point I was trying to make (probably should have been clearer): It's essential that after a trim, the ssd drive can run various housekeeping processes that help to maintain the drive's long term health and performance - executed when the drive is idle in order not to negatively impact...

How do aspm and other deep sleep capabilities affect the various background processes that maintain ssd drive performance and health over time, such as garbage collection after trim during idle? It was my understanding that the deepest power saving modes can prevent these from working properly...

why would the picoPSU be limited in 12V output? Naively I'd expect it to only be rated for 5V, 3.3V and -5V output, and pass 12V straight through from the external AC-DC block. Is there a relay to only pass through 12V when the machine is on, and is that limited to 120W ? Btw anecdotally, I...

Is it the dual chiplet interconnect? My system with 8600G idles at 10-11W at the wall and that's without the Asrock BIOS supporting C6 state and with the ssd, usb and ethernet controllers not using ASPM. 40W sounds like a major issue somewhere...

with the DMM it looks like pins 1-5 could be COM and 6-9 as +12V. Pin 10 is not obvious to me. Some remarks after watching the video from the Japanese user: * It was bought from a seller in the Kanagawa prefecture (not from US as OP or UK like mine). * Quite different S/N from mine, I'd say...

update: just received the board. The 40G MAC is definitely for infiniband; there's a jumper labeled as such. I'm wondering why the second 25G interface isn't present on the X10SDV-CIBF-AM041 because I'd assume it has the same Mellanox ConnectX-4 lx controller. The Japanese user also...

I bought this board from a seller in the UK. It was advertised as in working condition and with a Xeon D-1581. Will keep you informed on my progress to get it up and running once I receive it. From the photos in the listing, it looks like the power connector closely resembles HP backpane 10-pin...

This refurbished board catches my interest due to the very affordable price. Can anyone tell me if the DC_IN1 connector is optional? I.E. can I power the board with only a 12V power supply comnected to P12V_AUX1 - like is possible on many SuperMicro MITX boards?

the bolded part interests me; I'm trying to revive/refresh my A1SAi-2750F, and I got a Samsung 970 Pro 512GB inteded as data storage for ESXi, inserted on a 1U PCIe M2 M-slot adapter. However, nothing gets detected in the BIOS and in ESXi 7. lspci doesn't show anything. I've updated the BIOS...

Ziptie was the original plan, but the heatsink unexpectedly is flat at the top. This means no air will pass between the heatsink fins when forced from above, and I fear very poor cooling performance. I haven't seen this type of heatsink before on supermicro boards, and the review of the 16 core...
