Hello. I built my first gaming pc yesterday after having a prebuilt for 2 years. After a lot of troubleshooting, I have came to the conclusion that the 3rd and 4th ram slot seems to cause the pc to get the dram light and not boot. Any configuration works, as long as they are not in 3 and 4 (1,2, or 1 and 2). Is there a fix for this, or am I gonna have to get a replacement board? 

 

I have tried reinserting the cpu, trying different ram sticks, clearing the CMOS, loosening the cpu cooler, updating bios, moving the ram sticks around, and unplugging and plugging everything back in.

 

Specs:

MSI b550 Tomahawk

Ryzen 7 5800X

GeForce RTX 3070

G.Skill Trident Z RGB 16gb (2x8) 3600

Master Cooler 650w Gold Rated PSU

 

Thanks

I just had this issue today with the MSI MPG x570 motherboard.  Had Ryz9 3900x, upgraded to Ryz5 5600x.  After which, I couldn't boot with my 4 sticks of Gskill Ram.  Only could boot with 1 stick in slot 1.  Then put ram in slot 2 (leaving 1 in), boot, shutdown.  Put ram into slot 3 (leaving in 1+2), boot, shutdown.  Then the same with ram in slot 4.  I spent hours not being able to use slot 3 and 4, but I was putting both in at the same time.  every single stick needs to be put in one slot at a time, in slot order.  It's the only way I got it to work.  

 

In total, I spent 8 hours reseating and switching back and forth with CPU's.  Once the problem began, had same problem with both CPU's.  Tried clearing cmos a couple dozen times, cleaned cpu socket, checked pins, yelled at my cat, smacked my grandmother, cried, but finally tried what I said above and it worked.
