Question PC won't boot with dual RAM

[keith_kool]

Hi hardware fanatics,

After upgrading my PC it won't boot with dual ram anymore. I've been working on this issue for quite a while now but still haven't been able to solve it. I'm really running out of options.

hardware:
Aorus x570 Elite (latest BIOS version)
5950X
6800XT
4x G.Skill 16GB

So far I've tested (CPU without cooler just to check the boot process - CMOS reset before).
aorus elite X570 +

• 3900x & single RAM - boots (tested all RAM modules individually - all work on single RAM)
  • Test 1 - A1/A2 - 1x G.Skill 16GB
  • Test 2 - A1/A2 - 1x Corsair Vengeance 8GB
• 3900x & dual RAM - won't boot
  • Test 1 - A1+B1/A2+B2 - 2x G.Skill 16GB
  • Test 2 - A1+B1/A2+B2 - 2x Corsair Vengeance 8GB
• 5950x & single RAM - boots
  • Test 1 - A1/A2 - 1x G.Skill 16GB
  • Test 2 - A1/A2 - 1x Corsair Vengeance 8GB
• 5950x & dual RAM - won't boot
  • Test 1 - A1+B1/A2+B2 - 2x G.Skill 16GB
  • Test 2 - A1+B1/A2+B2 - 2x Corsair Vengeance 8GB

MSI X570 tordepo +

• 3900x & 5950x boots as normal with dual RAM
  • Test 1 - 2x G.Skill 16GB
  • Test 2 - 2x Corsair Vengeance 8GB

With the results of the above tests I thought the motherboard was the faulty component here. I'm still within guarantee and so I sent it for check&repair. After some weeks the answer I got was that the motherboard was ok and below testing has been done.

aorus elite X570 +
Ryzen 5 5600G & Ryzen 5 3600
Corsair Dominator 32GB kit
Crucial 16GB 3200 kit
A1+B1 post ok
A2+B2 post ok
A1+B1+A2+B2 post ok

Their comment: De memory controller is on this CPU, this might causes these problems. Weird because the CPUs I've tested work 100% on another motherboard.

What I don't understand is that they say the post is ok but they don't tell me the PC actually boots into bios. Is that the same post / booting into bios?

Now I'm really to the end of my options. Anyone here got any suggestions?

Thanks

As you've sorted out, it might be an IMC issue. you've done EVERY possible way and that was a good information for you. so yeah i would say that your IMC might be weak to use 4 rams on dual channel (cause 5600G and 3600 could do 4 ram dual channel no probs).
