G.Skill Memory Question (NewEgg Special)

So, I'm looking over the following at NewEgg for the Black Friday, and this is very tempting:

• G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-1600C9D-16GXM (Timing 9-9-9, Cas Latency 9) $120
• G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900) Desktop Memory Model F3-1866C9D-16GXM (Timing 9-10-9-28, Cas Latency 9, Voltage 1.5V) $122
• G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2133 (PC3 17000) Desktop Memory Model F3-2133C11D-16GXL (Timing 11-13-13-31, Cas Latency 11, Voltage 1.5V) $125
• G.SKILL Ripjaws X Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 2400 (PC3 19200) Desktop Memory Model F3-2400C11D-16GXM (Timing 11-13-13-31, Cas Latency 11, Voltage 1.65V) $130

This is going into a Gigabyte GA-Z97X-UD5H motherboard. I'm going to get two of these so that I get 32GB. I'm looking at the recommended memory list and only the DDR3 1600 is listed. Any recommendations from those in the field?

Under the specs page you just linked:

3.Support for DDR3 3200(O.C.) / 3100(O.C.) / 3000(O.C.) / 2933(O.C.) / 2800(O.C.) / 2666(O.C.) / 2600(O.C.) / 2500(O.C.) / 2400(O.C.) / 2200(O.C.) / 2133(O.C.) / 2000(O.C.) / 1866(O.C.) / 1800(O.C.) / 1600 / 1333 MHz memory modules

Usually you will have to (overclock them) set the timings to what they are rated at yourself if it is above 1600, that's all.

The motherboard should read the XMP profile, right?

You will not see anything faster than that in a QVL since anything faster is an overclock and your mileage will vary when you overclock your memory controller.

If you enable that in your BIOS/UEFI

I ended up ordering the two DDR2400 kits and using the VISA $25 promo. Then, I realized that I made a slight mistake.

I'm very ashamed of admitting this.... it's a very silly mistake...

Windows 7 Home Premium only supports 16GB.

I got very spoiled when my old workstation at work had 24GB of memory and I could run multiple vitualizations. That's why I wanted 32GB.

Oops.

Now, the good part is that Windows 8 supports 128GB, and it would follow that Windows 10 would have that same feature. Plus, there are always 64-bit Linux builds. So, my machine is ready... for the future!.

Just as an update.... the memory arrived today, and is installed on my system. So far, so good. The UEFI is reading it as DDR2400. As expected, Windows is only reading 16GB. But, then again, Windows 10 will be coming out late 2015, right?
