HUAWEI Matebook D15 Bom-WDQ9 - faulty onboard RAM

[JarzabekPZ]

I have a Huawei Matebook D15, MB DAH98PMBAB0 REV. B with faulty onboard RAM. Laptop starts but when loading Windows instantly gets BSOD's. Passmark Memtest shows multpile faults on test 11. Memory is itentified as 2 modules Samsung M471A5244CB0-CWE, which are available as standard so-dimm. Is it possible to desolder memory from such module and solder it on the MB? How to identyfiy which one on the MB is faulty?

Yes you can use them from standard so-dimm`s. The free version of Passmark Memtest won`t tell you which one is faulty. If one is getting hotter than the other that`s the bad one, you can test it for shorts with a multimeter after you`ve desoldered it.

I just checked under thermovision and half of them is getting slightly hotter when I run the test. Any tips what temp to set on hotair while desoldering RAM from so-dimm? Never did that and I don't want to burn them.

I replaced the whole RAM chips and still get the same fault. Anyone knows what can be the reason? Bad CPU? Maybe CPU reflow will help?
