Got an automatic offer for 70euros from ebay. Maybe seller will accept it.
Are you sure the offer was for the B565?

Canceled my initial order, offered 70, but in ran out.
Got an automatic one for 75 today, but realized afterwards, that it was for the B450... No I have to cancel again...

Ok, I am embarrassed. I am sorry I screwed up. The offer was for the B565 but it was 75 not 70. I deeply apologize for that :-(

Got everything (other then the case.... which will take another 1-2 weeks) setup today.


Findings so far:

2x16GB GSkill Trident 3600mhz ram is only working at 2133mhz (as far as I remember, i had issues with that kit in the past because of missing SDP entry.
Just ordered 4x16GB 2400mhz ECC UDIMMs

Regarding PCIe:

Looks like PCIE6 (the first one) is a full x16 slot, the B550 variant is only x8 according to its manual:
Code:
LnkCap: Port #0, Speed 16GT/s, Width x16, ASPM L0s L1, Exit Latency L0s <64ns, L1 <1us
                        ClockPM- Surprise- LLActRep- BwNot- ASPMOptComp+
                LnkCtl: ASPM Disabled; RCB 64 bytes, LnkDisable- CommClk+
                        ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt-
                LnkSta: Speed 16GT/s, Width x16
                        TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt-
BIOS offers 8x8x, 8x4x4x and 4x4x4x4 bifurication options

PCIE5 (top blue slot) should be x4, not tested yet (can't access because of the GPU, will switch slots later)

PCIE3 (bottom blue slot) is x4 as expected from inspecting the mainboard.
Code:
LnkCap: Port #0, Speed 8GT/s, Width x8, ASPM L0s L1, Exit Latency L0s <4us, L1 <64us
                        ClockPM+ Surprise- LLActRep- BwNot- ASPMOptComp+
                LnkCtl: ASPM L1 Enabled; LnkDisable- CommClk+
                        ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt-
                LnkSta: Speed 8GT/s, Width x4 (downgraded)
                        TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt-
Tested with a ASM2812 based 2xNVME to x8 card (with a single NVME disk installed, have to find another one for testing).



Is there an easy way, to list all PCIe slots including their width, even the empty ones?

Hello,
my B565D4-V1L finally POST with Kingston 16gb RAM and Ryzen 5700X,
my BIOS is L.031 so it is time to update BIOS anybody can provide URL/place for download?

Has anyone gotten this board to work with 4 DIMMs? I'm pulling my hair out over this. What I have tried until now:

I have four 16GB ECC UDIMMs @ 2666. With my R9 5950x, exactly one DIMM works, as soon as I populate the second channel, I get code 00 on the Dr. Debug LEDs and no post. Note, that this is INDEPENDENT of the channel, so Channel A and B both work if only one is used.

Then, I also tested the board with a Rzyen 5 5600 and got a different picture: now, dual channel works, so that can't be the fundamental issue. Three DIMMs also work (and are all recognized in the BIOS), however when populating the last slot I'm back to the 00 debug code and no post.
The BIOS does not seem to have any settings for RAM speed and voltages, so I'm at my wits end.

Any help is welcome...

EDIT: Both the 5600 and 5950x can handle four dimms in a different board, so I'm fairly certain it's not the memory controllers that are acting up. Also, I am on BIOS version L.034.

Can't cheer you up a lot, because :
I had similar case with X470D4U. Tried different CPUs, different memories, different configuration - just refuses to boot with 2 DIMMs. So I gave up.
I just assumed the board is buggy (its technically not DOA, as it was working) and moved on to X570D4U.

Its still hard for me to trace what could go wrong - apart of bad power/mosfet control (not being able to power up more than one DIMM at a time) or bad BIOS (which I dont see how can affect different RAM slots), I don't see what can cause this issue as the RAM is directly connected to the CPU and does not "talk" to any other parts of the MB

a deal for those who have DDR4 and CPU already right?
CPU might not be that bad to get 2nd Hand here in Denmark, approx. 50-60 EUR for a 3600 or so (not the best but "OK").

As for the RAM ... I just discovered I forgot like 20 x 16GB unbuffered ECC DIMMs on a Shelf :D .

For that price I would just buy a new Ryzen 5 5500 (but no ECC).
I'd rather pay a bit more and use the ECC RAM I already have.

Not interested in spending 100 EUR / 16GB DIMM or whatever the current Price is, since I already have the ECC Unbuffered one.

How is the idle power with using these boards? I am currently fine with the computational power from a n150 cpu for my Proxmox self hosting needs. That one uses 35 watt on full load. But the extra IO on these boards seems very nice to have. I already have 5 sticks of ECC udimm. So this seems like a very cheap way for me to create a 2 way cluster.

Bellow 30 watts seems fine to me. What cpu are you using? I am fine with the BMC using 5 watts since I will not have to buy a dedicated gpu. Have I understood this thread correctly that the BMC does not provide IPMI so for the first set up I will have to find a VGA monitor?

The under load condition is not a work load that currently worries me. But thank you for offering to test that for me!
