You won't find it capable of doing much in the gaming realm -- it's pretty much what you'd expect of an entry-level, $300-350 system.  
May I know if it's possible to change the clockspeed of ram in bios setup of Dell Inspiron 3581. I installed two 8gb RAM 2400mhz in my laptop but the reflected mhz in system.is 2133mhz only. Can someone give a step by step procedure in doing this. Thank you.
