R7515 does not post when all memory slots occupied
Hi,
I have 16 x 3200mts ddr4 16 gb rdimms from nemix ram. All sticks are identical. When only white slots are occupied (A1 to A8), the server boots up just fine. When all 16 slots are filled, the server is stuck at the system initializing screen. Each stick of memory has been tested to work in the machine, the R7515 just doesn’t finish boot when black (A9 to A16) slots are occupied.
help!

Hello,
please can you give me the details about memory ranking? Or any other details about the DIMM? Are DIMMS bought with server?
Thanks

Hi Marco,
Please find attached the specs of the memory kit. I purchased 2 of these kits from Nemix, which are supposed to be compatible with all major brand servers (Dell included).
Thanks,
Ken

I just read the R7515 manual at:
https://www.dell.com/support/manuals/en-us/poweredge-r7515/per7515_ism_pub/system-memory-guidelines?guid=guid-0534e253-8b5d-4116-b27d-78b133fdd07a&lang=en-us
Table 2 says that 8 GB rdimms are allowed for rank-1 type, but says nothing about GB.
16 GB is officially supported for rank-2 in the table. Could the problem be that the 16 sticks of 16 GB rdimm are all rank-1 and not rank-2?

As you are using third part DIMM's, we can not guarantee that it will work as it is not a supported oncifguraton hence not validated.
R7515 support below two 16GB DIMM. Both are dual rank
M04W6 - DIMM,16GB,3200,2RX8,8G,DDR4,R
YP9M5 - DIMM,16G,3200,2RX8,DDR4,M04W6
