Spent tons of time to figure this out: in /etc/sysconfig/memcached edit options

OPTIONS="-l 127.0.0.1 -I 3m"

then systemctl restart memcached to take effect.

Would recommend option -l 127.0.0.1 it secures to localhost usage only and -I 3m increases the limit as described above.

With Centos 7 I had no luck with these paths /etc/memcached.conf /etc/default/memcached

You can change the limit quickly by edit the configuration file [/etc/memcached.conf] adding: 

# Increase limit 
-I 128M

Or if you have trouble with SO config run it with command line directly 

memcached -I 128M

If you are using Memcache >= 1.4.2, this is now configurable. Here is an example of how to set this in your init script for starting Memcache on CentOS: http://www.alphadevx.com/a/387-Changing-the-maximum-item-size-allowed-by-Memcache

You can compile memcached and change the memory allocation setting to use POWER_BLOCK's, in the slabs.c file (or you can recompile and user malloc/free, but that is the greater of the evils).

http://code.google.com/p/memcached/wiki/FAQ#Why_are_items_limited_to_1_megabyte_in_size?

I would seriously consider what you are caching and how it can be more modular, > 1MB in active memory is large.
