Hej załoga,
Potrzebuję pomocy w namierzeniu problemu z lapkiem w tytule z procesorem Intel Xeon W-10855M. Posiada 4 banki pamięci a tylko w banku DIMM B działają kości, nie ważne jakiej pojemności i prędkości, ale tylko w tym jednym banku. Reszta nie działa, dioda baterii wyświetla 2 pomarańczowe, 5 białych mrugnięć. Na cewce od ramu mam 1.2V oporność na poziomie 80Ω z kością, 17Ω z dwoma kościami i 280Ω bez kości. Reset bios poprzez odpięcie bateryjki nic nie dał, aktualizacja bios też bez zmian
Może miał ktoś podobny problem

Hello!

- Start the machine without the RAM memory installed. What error code do you get in this case?

- Use a DDR4 RAM slot LED tester to test all four RAM slots.

NIe posiadam testera. Czy można sprawdzić inaczej? A jeśli zakupię taki tester to jakie odczyty podać ?
