Does it mean, that i have to bought MEM-2900-512U2.5GB, such kit, to upgrade my memory of 2921 to 2.5Gb?

And how can i use only- MEM-2900-2Gb?

Thanks:)

Nobody knows how to upgrade 2921 to 2.5Gb RAM?

Are you adding the 2Gig to your existing 512 to make it 2.5Gig or repacing it to have a total of 2Gig.

try it both ways.

Dmitri Popkov · ‎11-21-2012

Yea, i'm adding 2Gb to existing 512, i cant replace 512Mb, cause 512Mb is integrated in motherboard of 2921...

Still cant add 2Gb memory...

filiberto.aguirre · ‎12-04-2013

Hi Dmitri,

Did you clear this issue?

I got similar message;

%SPD info: DIMM0: Invalid DIMM type (only UDIMMs are supported)

%Dump of SPD info for DIMM0:

I tried to installed a DIMM 512 in 2911 router in order to have 1GB in DRAM. This DRAM was installed in 3945 and works fine but in 2911 the error message is displayed.
