 7. RAM
- OK this is not good at all. For Z77 and modern i5/i7 CPUs, you want DDR3 of 1.5V or lower. The RAM you picked is Enhanced CAS Latency (9-9-9-24) and 1.65V voltage. You don't want this at all.

Hello BlueFalcon, could you explain to me what is the problem with 1.65v for rams?

It is not the first time i see someone to say that is a bad thing. Thanks.
