    Test ATTO N322 network card ROM on Myllenox NIC

    I tried to order the Myllenox model that looked most similar to the ATTO NIC (as the ATTO card [is] a Myllenox NIC with modified ROM). Unfortunately, what looked like (close to) identical board+chip layouts in blurry & stock pictures were slightly different once purchased. Still, as the ATTO has a ROM which lets it get identified by a MacOS ... I wanted to try the ATTO ROM on the Myllenox NIC.

    Any reason [not] to:

    1. Back up the Myllenox ROM
    2. Copy the ATTO ROM

    3. Write ATTO ROM to Myllenox & test if the NIC is recognized by MacOS?
    4. If anything doesn't work, just revert the Myllenox ROM back to factory..?


    Myllenox ConnectX-4 LX CX4121C // MCX4121A-ACAT, Dual Port, SFP28

    ATTO NIC Model: N322, Dual Port, SFP28

    Attached pictures are actual pictures including the (identical) ROMs.

    Both ROMs are: 25Q128JVSQ 2143

    How Can I test PWM DM0365R?
    by chth96
    Hello
    I have power adaptor(220V/input, 12V 1.2A/output) which has symptom of fluctuating output DC voltage between 11.5V-12.2V.
    So I opened its plastic case and when switched it on, I heard constant tik tik sound from inside its PCB.
    I measured DC voltage between negative and positive pin of the largest capacitor(400v 10uf) and it was measured contant 300V.
    I also measured ESR value of all capacitors and I noticed that one of capacitor(KMG 16v 470uf), which located in the secondary side, have high ESR value(10 ohm),So I replaced it with same specification NXH capacitor....

    Samsung UN55JU650DF network/streaming problem
    by howardc64
    Fixed a 9 year old UN55JU650 by replacing backlight. Original backlight LED was still working after 27k! hours but terrible picture of course. Few LEDs were out, 5-6 lens fell off (bright white spots) and another few popped off with slightest force. Surviving LEDs were all slightly blue so picture has a blue tint.

    This TV runs older Tizen OS (updated to latest version, see pic) and have problems with network (wifi or ethernet) connection. The Tizen UI frequently switch to coax input source while changing content sources. . If no good signal (coax not connected, no prior antenna/cable...

    test active pfc power with lamp test
    by khelane
    Hello
    I have a big problem and that is that in some cases when repairing active pfc power supplies I cannot work with a test lamp. I can only get help with 5 volts standby and for starting and starting I have to work without a lamp and this way there is a possibility of parts exploding and other parts being added.
    Sometimes with a multimeter test the problems can be reduced to some extent, but I had several cases that had to be tested on and online and recently two varistors exploded. They had terrible resistance because the power supplies were over 800 watts.
    Is there a way...

    Mats / mods: detected and repaired GPU fault. Cant seem to test after!
    by chronic519
    Hello.

    GPU came in, green lines. Spent lots of time using to get the Mats / mods drive working (found on youtube).
    Found issue with a RAM block
    Replaced, green lines gone.
    Trying to test again, assuming getting the false positive. Originally had over 1K on a single bank. Now getting tosses low between banks.
    Used a good card to test and same results low errors 32+.

    I am just search for some form of command to do a full test on the GPU.
    I just ran the mats command with my good GPU and passed after roughly 40 min.
    The repaired one, ran...

    Home network connection problem
    by davg
    I just bought a new ThinkPad laptop and I need to connect it to my home network. I have several computers on my network and can see each other in File Explorer and the older ones can communicate with each other (even with the new one) but the ThinkPad can see the other computers but can't communicate with them. I get the (network error 0x80070035 The network path not found). I tried several scenarios that I found on line but none of them worked?? Since the other computers on the network can communicate fine I'm assuming the problem is with the setup of the ThinkPad? All computers are running Windows...
