Dual Channel RAM Causing Problems
« on: 14-April-19, 18:37:46 »

Building a brand new PC:

Motherboard: MSI B450I Gaming Plus AC
CPU: Ryzen 3 2200G
RAM: Patriot Signature Line 8GB (2 x 4GB) 2400MHz
Storage: ADATA SU800 128GB M.2 2280 SATA 3D NAND
Storage: Seagate BarraCuda 2TB SATA HD
PSU: Seasonic S12III 550W
Case: Thermaltake Core V1

Installing both RAM sticks causes the CPU error light to come on and booting halts, then system restarts and stops again with CPU error. When using either single RAM stick in either RAM slot I can get into the BIOS (I haven't installed an OS as I'd like this problem fixed first.)

Things I've tried to fix this:

  • Reseat both RAM sticks, also trying either stick in either RAM slot. System will only continue booting if single RAM stick is installed, no dual-channel.
  • Reseating all plugs into the motherboard (power/cpu power, fans, etc.).
  • Reseating CPU and not tightening CPU fan too much (I'd read it can be the cause of RAM slot issues.) Also checked CPU for bent pins but everything seemed fine there and CPU reseated and locked down just fine.
  • Updated the BIOS, which was only one version behind current (as of this writing, 04/14/19.)
  • Reset CMOS via jumper.

None of these was able to fix the problem. If there's something I haven't yet tried I'm open to suggestions. Otherwise, it's going to have to go back to Amazon.

I'm hoping someone here can help me out. Thanks.

Came installed with BIOS 7A40vA4, I updated to BIOS 7A40vA6 after I initially encountered problems. Didn't fix anything for me.

1/ Unfortunately, VA.60, who adds no more than "support new upcoming AMD CPU", is buggy for current CPUs! Go back to VA.40:
- Plug only 1 RAM stick in DIMMA1.
- Do a clear CMOS:
  . Power off PSU, unplug the power cord and wait that all mobo's leds light off.
  . Either
      . short JBAT1 during at least 20s
        (if you have not a jumper cap, use something like a screwdriver but be cautious to touch only the 2 pins of JBAT1) or
      . remove the battery cell during 15mn.
  . Plug the power cord and power on.
  . You would see a message. Choose to use bios default values.
- Use the tool developped by one forum's administrator: >>Flash tool[1.06] for MSI UEFI BIOS<< to downgrade to >>Bios VA.40<< (E7A40AMS.A40). Don't worry, it is reliable and it can downgrade even when M-Flash or Flash BIOS Button cannot.
2/ If downgrade has not resolved, plug only 1 RAM stick in DIMMA1, enter in bios setup and do a screen copy (press [F12]) of "SETTINGS \ System Information" for the DRAM part. Plug the other RAM stick in DIMMA1 and redo.
Hoping it shall help,
