ISR G2's -- support generic "approved" DRAM?

[aaron.storey]

Topic says it all.  We purchased some third party modules and our 2921's don't like them.  I'm trying to figure out if Cisco has changed their policy to not allow third-party upgrades, or if the modules are bad/wrong  type.  The error I get at bootup is:

%SPD info: DIMM0: Checksum validation failed

%Dump of SPD info for DIMM0:

Bring it to the module vendor, if they sell parts supposed to be compatible, they have to be.

Often el-cheapo DRAM's SPD isn't correct, but as Paolo notes, if vendor claims the module is "approved" then you shouldn't be seeing this error.
