You link lists a variety of gigabyte boards. If you want a guarantee it will work, either newegg or crucial's website is the way to go. Most tested ram won't match what you can buy; crucial probably won't charge a restocking fee; newegg sometimes does, but it depends on your problem. DDR3 normally runs at 1.5 volts; if your ram requires more, check the bios settings in the manual before ordering the board; only takes a minute to download.
I am a little new at this and my english ain't anywhere flawless so I am sorry if I misunderstood. Are you saying I can verify the ram compatibility through newegg? My current mobo is GIGABYTE GA-P55A-UD4P. I have seen somebody running the same ram on a GA-P55A-UD3P. The ram is G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 2000 (PC3 16000).
No. What I'm saying is that newegg or crucial may let you exchange the ram for little or no charge. To verify your ram works, you'll need to get lucky and find someone who's using it on your board choice. I've never had a ram compatability problem in 19 years of building. If your ram requires more than 1.5 volts, be sure your motherboard has enough voltage adjustments in the bios, or buy from crucial. Crucial will know your board specs and charge a little more. I just match the motherboard voltage to the ram specs; that's why you should download the board manual before ordering.
