Bulfinch Posted April 8, 2020 Share #1 Posted April 8, 2020 (edited) I added memory to my baremetal setup and was unable to boot afterwards. The boot process hangs after the 1.04 boot selection screen. "Happy hacking" I went from 1x8gb UDIMM to 4x 8gb UDIMM. When I reduced the number to 2x8GB UDIMMs I could boot. I believe the memory is good. I can see it in the BIOS. I also tried moving sticks around and mixing and matching to no effect. The system is a Dell Poweredge T30 with 6x 4TB WD HDD The memory is DDR4-2666MHz PC4-21300 ECC UDIMM 2Rx8 1.2V Unbuffered I'm using the 1.04b loader with the DSM_DS918+_23739 pat. I couldn't really find others having this problem. Thoughs? edit: clarify problem Edited April 8, 2020 by Bulfinch Quote Link to comment Share on other sites More sharing options...

Bulfinch Posted April 8, 2020 Author Share #3 Posted April 8, 2020 Thanks for the reply, they are all the same. The memory I'm attempting to use came as a pack of 4. I've removed the original UDIMM. Quote Link to comment Share on other sites More sharing options...
smoothmove Posted April 20, 2020 Share #4 Posted April 20, 2020 I have the same issue using a 918+ Jun's 1.04b on a Supermicro 1150 board. It won't boot unless you boot it with the amount of memory that the OS was installed with. I tried going from 16GB to 32GB (for no reason) and it won't boot. Removed the ram and it booted without issue. You aren't the only one, but only workaround it is install the DSM with the configuration that won't change. 1 Quote Link to comment Share on other sites More sharing options...
