Hi, that memory will be fine and highly recommended but it depends, do you use your processors integrated graphics or dedicated graphics? If you are using the processors integrated graphics then you will get better gaming performance if you use DDR3 1866 memory, that is if you are using your PC for gaming as well
I will Be using the IGPU..
I would like to get the 1866 BUT some other benches and feed back that it will only boot 1600 MHz
According to the following http://www.gigabyte.com/products/product-page.aspx?pid=... DDR3 1866 is natively supported. You will always read reviews and feed backs on how one person can run certain memory at lets say 1866 on your board and the other cant, it really depends on the brand of memory, memory timings, motherboard bios features etc. you are using. Even if it does not want to run at it's native frequency you can always just manually set it to run at DDR3 1600 speeds. If it's more or less the same price go for the DDR3 1866's for better future proofing. As for the brands, Ripjaws/Ares both would suffice but I'd recommend the Ripjaws.
EDIT: What APU/Processor are you using?
Also having the latest bios will increase compatibility with all memory configurations and other hardware.
Well that settles about my RAM
My CPU is AMD A8-6600K Richland 3.9GHz
another question for my future overclocking, since your xpert in Mobo.
I'm confuse on my gigabyte motherboard;
Should i pare it with GIGABYTE GA-F2A75M-D3H
(there is no 85xD3H chip set in my country) ( should i go for A85X chip set since its not D3H?)
