    GA-6VXDC7 v1.0 Mobo

    I've decided to use this as a DNS cache.
    I intend to recap the VRM and other caps on this board

    On the I/P side of the VRM, there are;
    5 of Choyo 6.3V 1200uF.
    This is obviously a +5.0V CPU VRM
    These will be replaced with;
    2 of 1500uF 10V, 3 of 1000uF 10V Pana FM.

    Looking at the VRM, on the O/P side CPU1 has;
    1 of 1500uF 6.3V Choyo
    2 of 1200uF 6.3V Choyo

    And CPU-2 has;
    1 of 1500uF 6.3V Choyo
    1 of 1200uF 6.3V Choyo
    The via for the other 1200uF is present but is empty.

    I intend to replace the O/P with;
    1 of 560uF 4.0V Sanyo OSCON SEPC
    1 of 2200uF 6.3V Pana FM
    1 of 1500uF 6.3V Pana FM
    Of course, being there is two CPU, each CPU will get the same.
    This is 300uF or so above what is in place.
    Should'nt be a problem.

    The rest of this board is sprinkled with a number of Choyo
    6.3V 1200uF and G-Luxon LD 330uF 25V as well
    as four GSC 10V 1000uF.

    Suprisingly, the G-Luxon cans are larger than the Choyo. Odd!
    Can't find the series to chk ESR, ripple and endurance.

    Going on past experience, it may prove better to replace these anyway
    as will be the case with the Choyo and GSC.

    I intend to install a pair of AcceleRAID 170s in this mobo to
    mate with the SCSI HDDs.

    I will replace the 330uF 25V G-Luxon with Pana FM 16V 470uF.
    The FM cans are smaller even so. It may be the case, these
    are fake. I'll crack open a can (not because it Xmas!), you never
    know, there may be a suprise inside such as;

    what i went through dealing with my mobo with dead onboard sound!
    by ChaosLegionnaire
    so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!

    i had to blow some dust off the board and heatsinks with the datavac as i didnt clean it up before putting it in storage. after finishing...

    Mobo MSI B550-A PRO password popup
    by Cerberuska
    Hello guys,
    I have interesting problem. My MoBo MSI running on Ryzen 7 w/o graphics just good. I swapped to Ryzen 5 5600G and on the boot I stuck with screen on picture. Enter Password. I checked BIOS setting with Ryzen 7, no security is enabled, BIOS password or TPM.
    BIOS I updated to last one.
    any suggestions?
    And same thing for two different 5600G, and yes, MoBo supposed to support it.
    Thank you...

    Dell G3 17 3779 - no display after mobo replacement
    by mrsith
    Hi guys,

    I have a friend's Dell 3779 that came to me with severely shorted mobo. Did not manage to isolate the cause, most likely that was a bga shorted. Went for a replacement motherboard. Got one from China, apparently it's been tested prior to shipping. The mobo starts up normally but I am getting no display whatsoever.

    Tried using external monitor, but being blind I am not sure if laptops goes as far as booting to Windows, a d without it I cannot get hdmi to work. Can't see boot menu options to make sure it boots to Windows. Went ahead and did a blind bios update,...

    Corsair cx600 psu & ASRock B450Pro4 mobo wont start
    by Ibod
    HI I have a PC using a Corsair cx600 psu & ASRock B450 Pro4 mother board that won't power on after a shutdown (replaced a dead drive in a raid array) Not the boot drive.

    With most things unplugged, including the 24 pin ATX connector, but not the ATX12v to cpu, I have +5.01V on the +5vsb pin 9 from the PSU. When I plug the 24 pin back in to the mobo, the +5vsb fluctuates between 1.1v & 1.9v.

    Not sure where to go from here ?

    Is the PSU at fault or is the mobo causing the problem

    Look forward to any help :-)

    If I plug the 24...

    Dell Inspiron 14-5448 - fan turns off and mobo keeps running
    by Felipe_Serra_83
    Hi, everyone. First post of an actual repair. I'm a technician but a complete newbie with laptops.

    So I got this Dell Inspiron to play with.

    No charger, so I connected to my bench PSU.

    The laptop also didn't include: hard disk (I added one of my own for testing, see below) and wireless PCB (but I doubt this could have anything to do with this particular failure).


    ------What it did (and didn't do)------

    1) I turned it on and it powered on. Powered down in 2 seconds by itself.

    2) Removed RAM, changed slot. Same...
