C2621XM 'sh ver' shows less memory then installed

[apartyka]

Hi,

After upgading RAM from 128 MB to 256 MB on 2621XM commands: 'sh ver' + 'sh mem stat' show only 128 MB. 'Sh c2600' shows 2x128MB.

What's the problem and does the router use all the available memory. I enclose output from these commands.Thanks for help.

Hi,

it seems so that the second module is not seated correctly. You should reinstall the DRAM again. In the moment the router works with 128 MB DRAM.

Thanks for reply.

We have ugraded +20 routers, everyone behaves the same way.

Don't you think 'sh c2600' shows that DIMMs were installed properly?

Hi Adam,

yes, i thinks thats possible that the DIMM was installed wrong. Perhaps try to change the slots and last but not leat, the module is defect.

May be a bug in the "show vers" for this router although I couldn't find anything on the bug database. What does "show mem" give you?

Currently the maximum memory used by Cisco IOS® Software is 128 MB. Some future Cisco IOS Software releases will use more than 128 MB of memory and will require this new ROMmon support to provide access to memory between 128 MB and 256 MB. Cisco IOS Software usage of more than 128 MB of SDRAM (in specific software images) is scheduled for
