Configure Failover on ASA 5505 with different RAM

[chhayheng]

Dear Expert,

Can I configure Failover on ASA 5505 with different RAM:
ASA-1 = 512MB
ASA-2 = 256MB

Beside of that problem is correctly.

Having different amounts of RAM on both ASAs is not supported. This is from the config-guide:

Hardware Requirements 

The two units in a failover configuration must be the same model, have the same number and types of interfaces, and the same SSMs installed (if any). Both units must have the same amount of RAM memory installed.

I think so. Some of them said and advice me to take a higher RAM size is active and Lower size is standby. That why I wonder.
Do you have any idea ?
