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.

 

[SuperMG]

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?

Anakart arızalı mı yani?

Maybe you make test

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.

8 çekirdekli bir işlemci olduğu için i7 10700K alacağım.

 

Çift kanal çalışmıyorsa anakart arızalıdır. Umarım öyle değildir. Anakartın fiyatı i9 işlemciden daha yüksek.

 

Anakart arızalı: Bu, RAM yollarının muhtemelen kırıldığı veya PCH'nin arızalı olduğu anlamına gelir.

 

Panoda şüpheli bir sıvı hasarı görmedim.

 

CPU: Bu, DRAM denetleyicisinin arızalı olduğu anlamına gelir.

I think you should have it checked by a specialist who can repair motherboards; you might not need to replace the motherboard after all.

No one helps where I live. They say they only repair certified brands, like what the heck.

 

I hope it's a CPU issue. An "ebay" repair job is like 300-400€ lol and we aren't sure if they can repair.

 

I'll try and see if one of my connections knows someone for repairs

Alright the motherboard is faulty...  I tried with an i3 10100F known for working with dual channel memory. Same issues as before.

 

For some reasons it booted with 1x16 3200MHz at 2666MHz and 2x16 3200Mhz at 2666MHz in single.

 

It also means the I9 10900KF is half faulty. It couldn't run a single 16 nor 2x16gb. Can only run 2666MHz sticks at 2133MHz

Yes the 10900kf  is faulty

Can you try re update bios and ec

I did update the BIOS with ch341A.

 

I erased the entire BIOS chip and flashed a stock 1.07.04 clean BIOS.

 

EC seems to be working. The EC doesn't control the RAM. EC is 1.07.zT.

 

The laptop is a zTecPC variant and I can't find the 1.07.04zT bios for it (Prema)

 

Laptop works only in single-channel.

 

Tried to adjust the LGA bracket pressure, cleaned the socket. Can't get it to work with dual channel.

[SuperMG]

The whole laptop is glitching now. It was working before. I didn't use it for a day.

 

No it's not a faulty GPU. No error 43 or BSOD. No artifacts just doing some screen flashing flickers

 

The screen flickers crazily and the laptop always goes to sleep mode after 10 seconds.

 

Dead PCH? Dead motherboard.

 

Waiting for the 300USD KM-G motherboard replacement and my custom 2 in 1 heatsink with watercooling for GTX 9XXM and RTX 40XX MXM

Dizüstü bilgisayarın tamamı şu anda arızalı. Daha önce çalışıyordu. Bir gündür kullanmadım.

 

Hayır, arızalı bir GPU değil. Hata 43 veya BSOD yok. Görüntüde herhangi bir bozulma yok, sadece ekranda ara sıra titremeler oluyor.

 

Ekran çılgınca titriyor ve dizüstü bilgisayar her zaman 10 saniye sonra uyku moduna geçiyor.

 

PCH arızalı mı? Anakart arızalı mı?

 

300 USD'lik KM-G anakart değişimi ve GTX 9XXM ve RTX 40XX MXM için özel yapım 2'si 1 arada sıvı soğutmalı soğutucumun gelmesini bekliyorum.

I'm sorry to hear about the problem you're experiencing. Buying a new motherboard makes the most sense. I hope everything goes well.

At least I found a KM motherboard that's like 2.5 times cheaper than on AliExpress. The dual channel and the rest work. This sm motherboard has too many issues, new ones appearing each day. No idea if that i9 10900KF got defective because of that motherboard or it's just an unlucky chip.

En azından AliExpress'teki fiyatından 2,5 kat daha ucuz bir KM anakart buldum. Çift kanal ve diğer özellikleri çalışıyor. Bu SM anakartın çok fazla sorunu var, her gün yenileri çıkıyor. i9 10900KF'nin bu anakart yüzünden mi arızalandığını yoksa sadece şanssız bir çip mi olduğunu bilmiyorum.

ben sm cihazında benzer bir sorun yaşamadım. sen biraz sansızdin yada orjinalinin gerçekten arızalı

It supports 10th and 11th gen. No 9th gen support.

Okay i know 10th and 11th gen same socket but asking about the bios cpu support

Only sm can't support 11th, only supports 10th
