4 slots of DDR3 SODIMM modules

Jump to solution

Is it possible to connect 4 SoDIMM slots to a Kintex7 FPGA, to a single DDR (MIG 7) controller? And if so, how?

Hello @goychman,

I'll follow up and suggest moving on to an UltraScale based design since DDR4 supports much higher densities where even 128GB is possible for a single RDIMM.  For 7-Series you would have to use two controllers with dual slot 16GB SODIMMs to achieve this density.  Maybe there's a way to split the traffic/buffers between two cores?

I need 64G memory (4*16G) to be connected to the FPGA for a new project :)
