Hi folks,
I have a few R815 servers that I've upgraded from 2 CPUs each to 4 CPUs each. The servers have 256GB of RAM in the form of 16x16GB PC3L 12800R sticks.
After first seeing that message, I concluded that it was likely because I left the 16 sticks in slots A1-A8 and B1-B8, despite now having 4 CPUs. However, after rearranging the sticks to be in A1-A4, B1-B4, C1-C4, and D1-D4, I still get the error on boot.
As a workaround for now, I've disabled the keyboard prompt on the error. But I still assume that something isn't right. The manual that I saw does indicate that A1-A4, B1-B4, C1-C4, and D1-D4 is the proper layout for a 4-CPU system, though the capacities seem dated. (It only lists capacities of up to 8GB per stick)
Is it possible that my sticks need to be configured at 8 sticks per CPU?
Thanks!
