Issue #598 has been updated by Dawid Wrobel. I flashed the stock BIOS and the system boots just fine. dmidecode shows: ``` Handle 0x003C, DMI type 17, 40 bytes Memory Device Array Handle: 0x003B Error Information Handle: Not Provided Total Width: 64 bits Data Width: 64 bits Size: 32 GB Form Factor: SODIMM Set: None Locator: ChannelA-DIMM0 Bank Locator: BANK 0 Type: DDR4 Type Detail: Synchronous Speed: 3200 MT/s Manufacturer: Micron Serial Number: EB37855C Asset Tag: 9876543210 Part Number: CT32G4SFD832A.M16FF Rank: 2 Configured Memory Speed: 2400 MT/s Minimum Voltage: 1.2 V Maximum Voltage: 1.2 V Configured Voltage: 1.2 V Handle 0x003D, DMI type 17, 40 bytes Memory Device Array Handle: 0x003B Error Information Handle: Not Provided Total Width: 64 bits Data Width: 64 bits Size: 32 GB Form Factor: SODIMM Set: None Locator: ChannelB-DIMM0 Bank Locator: BANK 2 Type: DDR4 Type Detail: Synchronous Speed: 3200 MT/s Manufacturer: Micron Serial Number: EB3779C4 Asset Tag: 9876543210 Part Number: CT32G4SFD832A.M16FF Rank: 2 Configured Memory Speed: 2400 MT/s Minimum Voltage: 1.2 V Maximum Voltage: 1.2 V Configured Voltage: 1.2 V ``` ---------------------------------------- Bug #598: Lenovo m920x RAM compatibility issue https://ticket.coreboot.org/issues/598#change-2106 * Author: Dawid Wrobel * Status: New * Priority: Normal * Target version: none * Start date: 2025-06-04 * Affected versions: main ---------------------------------------- Hi there, I recently flashed my m902x with coreboot (25.03-643-g69a067a9d62c-dirty). Everything seemed to work fine until I tried upgrading the memory from a single 8GB stick to 2 x 32GB (Crucial CT2K32G4SFD832A, https://eu.crucial.com/memory/ddr4/CT2K32G4SFD832A). The system won't boot in any configuration (a single stick in either slot or both). I get no display out, the system stays on and stuck, apparently, with high CPU usage causing fans to kick in. I have no serial port in this system at the moment (backordered an extension module), but am wondering if it will be of any help and if there's any other way to debug it? Do note that the system *is* capable of running 64GB memory, as it was reported already, so I wonder if this is a matter of some SPD misconfiguration? Crucial lists the 2x16GB modules as compatible with this system (https://eu.crucial.com/compatible-upgrade-for/lenovo/thinkcentre-m920x-tiny#memory) and they have seemingly identical specs as the 2x32GB ones. -- You have received this notification because you have either subscribed to it, or are involved in it.
