Be happy :) . This is a low-end AMD Ryzen Motherboard.And depends what you want to do with 2x25 gbps.

You suggested 2x25GbE cards on x4 electrical, which doesn't make any sense if you truly want to utilize the network, not just to say its attached to the motherboard.

Yeah theoretically, but I think only x4x4x4x4 is supported ...

As you've seen, reading the manual doesn't always lets you think correctly ... the board supports x8x4x4, along with few other things, missing from the manual, as stated in the thread.

EDIT 1: you will NEVER be able to achieve 25GBe speeds anyway. I assumed you meant 25gbe ;) .

Since it seems you want to nit-pick things - its 25GbE - I am sure you can check the manuals about that one too :)

You can get up to 32gbps so 25gbps is a possibility. Do you want to route 25gbps from one Port to the Other ?

Furthermore the Mellanox ConnectX-4 LX is a 2x25gbps NIC which can often be bought 2nd hand for less than the Intel X710-DA2 which is only 2x10gbps. Just saying ;) .

Sure, buried in one of the many Pages :D. Suppliers and Manufacturers also lie. Nothing new there unfortunately :rolleyes:.

I always use gbps but OK if you think a Byte (B) is the same as a bit (b) that's up to you ;).

Here are some items I ordered in the past
Click to expand...
I got a couple of the PCIe X16 to X8X4X4 Adapter that you suggested, to see if I can at some Point make a use out of it :D .

I'm curious how you managed to use that X8 Slot however.

Do you have a Chassis where the PCIe Cards are installed in a transversal Manner ?

Otherwise it might be possible to "displace" it with something along the Lines of

But then I would have to insulate the existing (unpopulated) SLOT4 and place this Adapter PCIe Socket on top of it. But then the NIC would probably stick 1-2 cm too tall for the 2U or similar Chassis :( . And Nope, I don't have any PCIe Slots that are outside of the Motherboard and the only transversal one on the Silverstone ML03 is on the wrong Side and already blocked once the CPU Cooler is installed anyway.

A low profile card in the x8 slot has the same height as a normal full height card.
The screw hole does not line up perfectly unless you got a card with both notches in the bracket tho (low/full profile has screw holes in different positions).

I got these adapters with 2x 25gbe cards on the x8 slot for all my ryzen builds.

OK, so it's not a 90° Adapter actually, the other Card (NIC in your Case) goes in straight from the Top ?

Then it's even MUCH WORSE. It's will stick 4cm out of the Chassis if I do that :rolleyes: .

EDIT 1: Maybe that works well for a Low-Profile Card when used in a Full-Height Chassis/Case with a Full-Profile Bracket. But to stay within 2U that simply will NOT work :( .

EDIT 2: Example with Intel X710-DA2: with the Low-Profile Adapter it's already flush with the PCB
1743929752664.png

If you raise the Base (which is going to be the X8 Slot from the Adapter) by 4cm, that goes 4cm out of the Case/Chassis ...

EDIT 1: yeah, I re-read what you wrote. The Low-Profile Card becomes Full-Profile Card. So you need a 4U (not sure if 3U fits 12cm, maybe very tight ?) or bigger Chassis basically :( .

Any idea for some cheap and good NVMe Storage ?

I was actually planning SATA SSD since I have many of them .... BUT then the SSD Hot Swap Bay Cost will probably end up being quite expensive. These Icy Dock 4x2.5 in 5.25'' Adapters have more than doubled in Price since a few Years back :( .

I saw some Good Deals for Consumer Samsung 980 for 1TB/50 EUR or so.

This also looks interesting but seems WAY too good to be true for an enterprise NVMe Drive. I smell scam but he sold 315 of them ...

I will try to use 3 of these boards as a storage cluster training environment:

1. OS (Debian or Alma) will be installed on cheap SATA SSD connected via internal USB3 adapter to SATA. I guess you could use internal USB3 connector for unRAID as well.
2. PCIe x16 split with 8x4x4x - bifurcation card I still have around with x8 used for dual-port ConnectX-3 Pro for internal IB cluster and data transfer and 2x Optane 1600x (58GB) as read/write cache.
3. PCIe x8 used with M.2 -> SATA 3.0 card for 6x SATA HDD's. Speed should be kind of ok with x4 electrical speed only.


Not clear about cpu as I need ECC for sure.

exactly as Cruzader mentionned, a low profile X710 in the upper X16 (mechanical, X8 electrical) slot of the riser, and indeed the low profile brackets, more or less match with a bit of trial and error into a full height pcie of the case

So a 2U system would become 4U essentially. Not a Problem if you already planned to use a Midi ATX Tower / 4U Chassis of course. But I'm coming from the Opposite Angle and if I need to go from 2U / Silverstone ML03 to 4U / Midi ATX Tower Form Factor, it's also another Volume that the Case Occupies :( .

I expected the same to happend with this as the mc12-le0, their remaining stock is bought up by resellers that then take over the market.
I was tempted at making a 15€/ea offer for a few hundread boards myself.

The alpha38 account now listing single boards at a higher cost is the same seller tho.

Few hundreds :eek: ? WHAT are you doing exactly ? Reselling them or ?

I'm curious what you are running on those Compute Nodes you mentioned previously ;). Some Kubernetes Cluster ? But with that kind of Power it seems more like a Hosting Farm or something like that :oops:.

I assembled my second board with 5700X in SilverStone RM23-502-MINI with Dynatron A47 cooler.
Rear USB works, VGA output works with default settings (CSM = enabled, video Oprom policy = legacy only, boot mode=legacy)

I used ECC RAM. dmidecode did show Total Width greater than Data Width, but did not show "Error Correction Type: Multi-bit ECC" for memory.
I will have to investigate further.

That's actually a quite nice Case. If it wasn't double the Price of the Silverstone ML03 I might have considered it.

And Multi-Bit ECC I think is only supported with REGISTERED Memory, isn't it ? Or at least that was my Impression in the Past. This memory here is unbuffered.

However, looking at Supermicro Website for the X10SLM+-F they state:


Error Detection
  • Corrects single-bit errors
  • Detects double-bit errors (using ECC memory)


A Motherboard Supporting Registered Memory such as the X10SRL-F state the same:

Error Detection
  • Corrects single-bit errors
  • Detects double-bit errors (using ECC memory)

So I guess it depends if you mean "Single Bit" Correction vs "Multi Bit" Detection.

My Output for dmidecode shows Multi-bit ECC only for the L3 Cache at least (on Supermicro X10SLM+-F).

It seems "Error Correction Type: Multi-bit ECC" might be only with registered RAM.
On a E3 1230 v3 system using unbuffered ECC DDR3 is see in the "Physical Memory Array" section:
"Error Correction Type: Single-bit ECC"

However with my 5700X I have at the moment:
"Error Correction Type: None"

Very weird. Are you sure you are in the right Memory "Section" (32GB or 64GB depending on what you have installed) ? Although I guess also the L2 and L3 should have some kind of ECC (like mine shows).

This is from an ASUS ROG STRIX B550-A GAMING Consumer Motherboard with AMD 5950X and 4x32GB ECC Kingston RAM.
Not sure why I have multi-bit ECC though:

There are ECC settings in the bios:
Advanced -> AMD CBS -> UMC Common Options -> DDR4 Common Options -> Common RAS -> ECC Configuration

"ECC Enable" is set by default to "Auto".
I will test later if setting it to "Enable" activates ECC for Linux.

Just for clarification that these mysterious - V1LQ5 boards are nothing other then normal V1L boards. No M.2, no PCIe-Slot4 and so on. Why you guys keep separating them?
