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 (1 and 2) 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

So single channel works in slot 1 and 2.

 

When I try single channel for slot 3 or 4. It doesn't boot.

 

CPU socket pins, everything looks clean. Nothing is broken or missing.

 

Used an air blower and a brush to clean the socket, still the dual channel doesn't work.

 

Is that a motherboard issue or a CPU issue?

I have the 170cm model as well. It’s equipped with an i9-10900K CPU, 32GB of RAM, and an RTX 3080 GPU. I haven't encountered an issue like this. The latest XMG BIOS version is installed. Your RAM slots might be faulty; either slot 3 or 4—or both—could be the problem.

So the motherboard is dead?

I'll buy an i7 10700K since it's an 8 cores CPU.

 

If dual channel doesn't work then the motherboard is dead. I hope it's not the case. The motherboard costs more than the I9.

 

Dead motherboard: It means that the ram traces are probably broken or a faulty PCH.

 

I didn't see any suspicious liquid damage on the board

 

CPU: It means the DRAM controller is dead.
