Clevo X170SM-G dual channel problem

[SuperMG]

Hello. I bought a Clevo X170SM-G with 10900KF and RTX 3080 16GB with 32GB of RAM. It has the watercooling 2in1 heatsink.

 

Laptop wasn't posting so I reflashed it with a 1.07.04 stock clean ME bios.

 

Still no boot. So I had to remove the RAM from slot 2/4 and I only used one slot and it worked.

 

The laptop only posts with single channel configuration and it runs at 2133MHz.

 

The previous owner told me that the laptop was working perfectly fine and he didn't use it for a week and the laptop wouldn't post.

 

I cleaned the CPU pads. There were some stains but this didn't help.

 

Is the motherboard dead? Or is the CPU DDR controller dead?

 

All the memory slots are working in single channel.

I try this with 2 slots in single:

 

1x8GB (2666MHz) works at 2133Mhz, boots to OS 

 

2x8GB (2666MHz) works at 2133MHz, boots to OS

 

16GB (3200MHz) + 8GB (2666MHz) works at 2133MHz, boots to OS

 

2x16GB (3200MHz) doesn't work, no boot.

 

1x16 (3200MHz), doesn't work, no boot.

 

Anything in dual channel, no boot.

 

All the RAM sticks get hot in the touch, so they are getting powered.

 

 

Is that a CPU problem?

The processor's memory controller might be faulty, or there could be an issue with one of the RAM slots.

Hello. I'll try with another CPU. Like the 10100F. I have a none bent socket. Found one CPU locally for 35 after taxes
