    The Infamous Mikrotik CRS354-48P-4S+2Q+ Thread

    Thank you for your feedback tenos, this input show the randomness of the issue. (3 / 9 affected..) At our side we have tested SwOS in a setup where it was only passing IPMI traffic over 4 differnt vlans and we still got the issue. Did you order them all at the same time or do you have different...

    The Infamous Mikrotik CRS354-48P-4S+2Q+ Thread

    This is some very interesting feedback as it show that some models are running fine in some use cases... At our side we also had them in datacenter, simple configuration, no changes and got the port freezes on all devices quite quickly. We had one unit that kept running smooth for 12 month and...

    The Infamous Mikrotik CRS354-48P-4S+2Q+ Thread

    Regarding the noise, as long as you do not have all ports plugged it is reasonable... but if you choose to get this switch, be prepared to get only 40 copper ports available at best and globally a crippled device. Then yes it's cheap and reliability is sometimes random but we are here at a...

    The Infamous Mikrotik CRS354-48P-4S+2Q+ Thread

    Hi everyone, I wanted to create a thread regarding this particular switch from Mikrotik, namely the CRS354-48P-4S+2Q+. While this looked like a dream of a switch, packing 48 copper 1G ports, 4 SFP+ Cages and 2 QSFP+ and dual PSU for less thant 500$, it turned out to be a nightmare and an...

    Asrockrack X470D4U and zen3 / Ryzen 5900X support

    Follow up : I updated with bios 4.02J and it boots ok with Ryzen 5900X but IPMI is behaving strange, power state is not correctly asserted and systems seems to freeze randomly, lots of " FRB3/Processor Startup/Initialization failure - Asserted " errors in the ipmi log. Reverting back to...

    Asrockrack X470D4U and zen3 / Ryzen 5900X support

    Hello I was convinced that I read somewhere that a lab bios was available for the X470D4U to support Zen3 CPU and more specifically the Ryzen 5900X. I can't find it anywhere. I know the X570D4U has had one as we have some of them aldready running zen3 cpu but did I dreamt the X470D4U had one too ?

    1U Heatsink for AM4 and X470D4U?

    Here is the pic, finally it's a X570D4U board but this is nearly the same, you get a little bit more space for the pipes on the left of the CPU.

    ASRock Rack X570D4U

    Hello I have updated my board with the "lab" bios available from their site and BMC remains available and functional, sounds like RMA is indeed your only option.

    1U Heatsink for AM4 and X470D4U?

    A bit late to the party here but we also built 1U servers with X470D4U and after much testing / cpuburning we have settled for the Dynatron L3 watercooling. We use it with Ryzen 3950X and no fan based system could cope with the speed at which it heats up. Now with the L3's, even under heavy...
