 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.

sandy/ivy bridge chipsets and the ddr3 ram spec are designed and call for 1.5v running above this may shorten lifespan of motherboard/ram and the added heat does not help. it also reduces your ability to OC the ram where you may use higher voltage to add stability. some motherboard manufactures may not honor warranty if they find you using ram over 1.5v as they normally ask for model number … intel also asks for this information  but i have never heard of them declining a RMA for this issue
