It'll say pretty clearly under the Details tab on Newegg and on the manufacture's web site what voltage it's rated for. If it's not, it'll just fall back to whatever the nearest JEDEC recommended settings are (1333 usually).
So, if i buy a RAM with 1600MHz and 1,5V I could just pick a RAM with 1333MHz? If thats true, then these is the part I have come up with:
Case: CM Storm Scout Midi Tower
PSU: Corsair TX V2 650W PSU
DVD writer: Sony Optiarc DVD RW Writer, AD-5280S
RAM: Kingston ValueR. DDR3 1333MHz 8GB, CL9
Hard drive 3.5": Seagate Barracuda 1TB (SATA 6GB/s (SATA 3.0), 64 MB Chache, 7200RPM, 3.5")
Hard drive 2.5": Crucial m4 SSD 2.5" 64GB
Graphic card: Sapphire Radeon HD 6950 1GB GDDR5
Processor: Intel Core i5-2500K (w/ fan)
Motherboard: MSI P67A-GD65 B3, Socket-1155
Monitor: HP x2301 23" Micro thin LED
Operative system: Windows 7 Pro
If there is any more parts that it is smart to change please tell me.
Is the PSU fan noisy?
Is the SSD and HDD and the motherboard good?
Sorry if I ask alot, but I want to get a good computer=)
