DDR4 Topology support Intel Xeon E-2276ME

Hello Sir/Mam

Does Intel Xeon E-2276ME support 1R(single rank) clamshell topology? Can we map 2G X8 DDR4 in this topology?

Another Query if we are using 32 Bits out of 64 Bits of DDR4 . Does ECC work in this case if yes where should it be mapped last 8 bit or in between?

Gentle reminder for the same

Hello @Pkaur,

Thank you for contacting Intel Embedded Community.

Clamshell topology for memories are not supported, you can use Memory Down, UDIMM or SoDIMM. Please check section #570805 - CFL EDS Vol1, section 2.

Processor's architecture is 64 bits. When ECC is used, it assigns some portion of the memory to it, you don't have to worry much about it.

You may check document #572062 - Design In, page 79, you have the Memory Configuration for ECC.

Best regards,
