Min Required Flash Memory & DRAM

[admin_2]

I have Cisco 2821. With IOS version:c2800nm-ipbase-mz.123-8.T8.bin

Cisco 2821 (revision 53.51) with 253952K/8192K bytes of memory.

DRAM configuration is 64 bits wide with parity enabled.

239K bytes of non-volatile configuration memory.

62720K bytes of ATA CompactFlash (Read/Write)

can anybody tell me can i upgrade latest IOS 12.4 on my router? or I need additional flash memory & DRAM hardware before for this ios upgrade.??

Please advise.

You can use the feature navigator to determine mem/flash requirements for your desired image:

but I think 64 MB Flash and 256 MB RAM should be enough for the latest 12.4 releases.

You can go ahead with this image c2800nm-ipbase-mz.124-11.T1.bin which requires 64mb flash and 256 mb dram.
