I recently got an MSI X399 Gaming Pro Carbon motherboard to run my AMD Ryzen Threadripper 1950x, the issue is that it won't start up. I have it properly connected and I have redone my cabling twice. Beyond that I have tested two PSUs I was using both were fine. I can see the power button on the motherboard lit up from ambient power. However, when I hit my power button on both my case and motherboard nothing happens. No LEDs turn on and no fans spin. I have attempted to jump it by hitting my power switch pins with a screwdriver, but I have had no luck as nothing happens again. I have checked the pins on the LGA socket and none of them are missing or bent so I am scratching my head.

My exact parts besides the PSU and GPU:

CPU- AMD Ryzen Threadripper 1950x
RAM- G.Skill DDR4 RAM clocked at 3200 mhz
Motherboard- MSI X399 Gaming Pro Carbon AC

Ok well try removing all but one stick of RAM and test. Test each stick one at a time to see if they work. Unplug all drives and just try getting to bios. If nothing works take the motherboard our of the case and set it up on your motherboard box. This tests if the motherboard is grounding on the case.

Got the same problem when I remove the 230 AC.
Only way to make it start again is to power it off till power is dissipated (takes about 30 sec),
then press for 10 sec the bios reset button at the back next to the usb ports, then turn the AC on again and press the power button, it will start this time.

normally when it indicates that there is power present at the board like the on/off power button lighting up, but won't boot, chances are that its wrong configuration of the RAM. Have you also tried removing all but one of the RAM sticks? Have you made sure that the stick is in the '1st' recommended slot? if you go through the manual you should see which slot is the 'first' slot you should use.

ON RYZEN ONLY USE DUAL CHANNEL NOT 2*SINGLE

ON THREADRIPPR ONLY USE QUAD CHANNEL NOT 2*DUAL


inside ram,(hardware ,IC and pcb )single,dual,quad not same ,completly diffrante ,, many people think = dual =2*single channel ram or quad =4* dual ram



you must use only ram, write on box QUAD for threadripper (dual for ryzen)

if you put wrong ram your system cant start , even if start , hiccops rip in windows, harm your cpu

change your ram to this
gskill ripjaws4 4*8 3200=250$
or
gskil ripjaws4 4*4 2400=150$
