Arria 10 GX Development Kit -- DRAM Revisions?

Hello,

Looking for help with an Arria 10 GX Development kit (OPN#: DK-DEV-10AX115S-A), if anyone from Intel FPGA can please help out.

Pin Height for Replacement Modules are different?

We appear to have different versions of the kit...or modules... where while attempting to replace one kit's DRAM module, it does not appear to slot into properly into the board. Looking further, it was noticed that the pin height for a previously working module is different than a newly ordered module. The newly ordered modules, MFG PN: HLDC-DDR4-A. These DRAM modules appear specific for the Arria 10 GX development kit. Is there something we can do to ensure that we get replacement DRAM modules that are correct for our development kit? What can we do about the kit we have currently?

 

Memory Chip Used is different?

It appears that the memory chip for older DRAM modules were MT40A256M16GE-062E and that current modules are MT40A512M16LY-075; both modules significantly different in specifications. Is there a way we can ensure that we are getting replacements for *-062E instead? We have a design working for *-062E and want to continue to use *-062E, but don't want to have to constantly change replacement suspected failing modules.

Regards,
Kris
