New ContributorCan the Stratix-10 SOC Dev Kit's DDR4 SODIMM memory can be upgraded from 16GB to 32GB?
My question is whether the Stratix-10 SOC Dev Kit's DDR4 SODIMM memory card can be upgraded from 16GB to 32GB?
The Dev Kit currently has a 16GB (x72 w/ ECC) DDR4 SODIMM memory card (Micron MTA18ASF2G72HZ).
From reviewing the board's schematic, it appears that the hardware may support 32GB DDR4 SODIMM cards:
- The 16GB card uses address lines A[0:15]
- The 32GB card uses address lines A[0:16]
- The other addressing signals are the same between both parts.
- The Dev Kit’s schematic shows that A16 is connected from the FPGA to the SODIMM connector, which is promising.
- The EMIF IP would need to be re-configured from 16GB to 32GB.
If the Dev Kit supports 32GB DDR4 SODIMM memory cards, here is one I found:
32GB (x72 w/ ECC) candidate part: Micron MTA18ASF4G72HZ-2G6
The Micron website shows that this part is sampling. I am checking on availability.
Thanks for any information or comments.
Hi Sir,
Yes, it is upgradable since the A[16] is connected to the board. Recently I am also upgrading the DIMM from 16GB to 32GB on the other boards. The changes are only open to the GUI, change the address pin setting, re-generate. Add the location assignment for the A16. The design is work now!
Anyway, please be reminded to review the timing parameter and see if it still the same.
