1866 MHZ CL10 vs. 1600 MHZ CL9

[Aubtin]

I'm looking at these two options:

1. http://www.amazon.com/Crucial-Ballistix-PC3-12800-BLS2KIT4G3D1609DS1S00-BLS2CP4G3D1609DS1S00/dp/B006WAGGUK/ref=pd_bxgy_147_img_y#Ask

2. http://www.amazon.com/Crucial-Ballistix-PC3-12800-BLS2KIT4G3D1609DS1S00-BLS2CP4G3D1609DS1S00/dp/B006WAGGUK/ref=pd_bxgy_147_img_y

They are both about the same price, and my motherboard only supports 1600 MHz..
Motherboard specs: http://www.gigabyte.com/products/product-page.aspx?pid=4713#sp

Does the HyperX Fury downscale the timing to CL9 when it goes down to 1600 MHz? If not, should I go for the Crucial, or stick with the Fury for possible future use at the 1866 MHz?

Thanks!

Take your pick.
The 1600 is just a speed at which the motherboard will boot.
You can then set the speed to 1866 in the bios.
From a real app performance point of view, or fps, there is virtually no difference in effectiveness.

Always buy RAM rated at the speed you're going to use it. If they're binning them at 1600 you may have issues setting the XMP profile higher

The 1866/10 will show slightly better performance than the 1600/9. With the Fury it will use PnP to set itself up to the highest data rate it can run, which in part will depend on the CPU used and the BIOS. From there you can make manual adjustments
