Use the proper options:
Code:
$ stress --cpu X --vm 1 --vm-bytes=Y

where Y is the number of your cpus, and Y the amount of memory you want to be used. For example, for a 4 cpu system with 6GB free memory, you could use:
Code:
$ stress --cpu 4 --vm 1 --vm-bytes=5G

Or use Prime95: Free Software - GIMPS, which is more stressing.

To test the ram from inside the OS, you can use memtester: memtester version 4

NAME

       cpu - A tool for user and group administration

SYNOPSIS

       cpu [OPTIONS]

DESCRIPTION

       CPU is a tool for user administration, that was initially based on FreeBSD's pw(8). This tool will allow you to administer users and groups

       tion, or help improve the man page.

OPTIONS

       There are two kinds of options; options for CPU and options for CPU modules.  There are only four options for CPU, they are as follows:

       -C configfile, --config configfile
	      The configuration file to be used by CPU. The options in this file are used for CPU modules.

       -h, --help
	      Display help for CPU. If specified in conjunction with the -m option the help for that particular module is displayed.

       -M method, --method=method
	      This  is	the method of administration. Current options are ldap or passwd (passwd is not yet working). This can be specified in the
	      configuration file.

       -V, --version
	      Display the version of the software.
