Hi,
First of all, you are hijacking this thread but since it's so old I'll respond. It needs to be closed.
If you went to your motherboard website you'd notice it lists up to 1866MHz RAM. Let's be clear, ANY DDR3 RAM will work in general, more specifically:
1. The motherboard BIOS contains PROFILES for RAM. Ideally what you do is go into the BIOS and set the profile to "XMP" or whatever and the proper timings and frequency will be applied. Compare these to the values listed for your RAM.
2. You can purchase higher frequency than what you motherboard supports but that's really a waste of money. It will work likely, though. Although, I have seen 2133MHz DDR3 work in motherboards listed to 1866MHz so I'm not sure what's up with that.
3. For best compatibility purchase RAM that is on the LIST of approved RAM for your motherboard. Your support site should have a list. It may not be up to date though.
4. I believe you can overclock the RAM beyond the top limit. In general, I don't recommend that. Use the "XMP" profile for best compatibility
Other tips:
1. 8GB is ideal for gaming. More is a waste (needed only for video editing and similar tasks).
2. In some cases 2133MHz is better than 1600MHz for gaming but that's rare. You'll also need a fast CPU similar to an i5-3570K to take advantage. If in doubt spend a little more on 1866 or 2133MHz RAM. To be clear, 2133MHz vs 1600MHz MAY provide a benefit in some games depending on the game and your other hardware whereas 16GB vs 8GB will provide ZERO BENEFIT. ZERO.
3. Don't forget to flash your BIOS to the latest as well as your important motherboard drivers (Intel can even scan and recommend updated drivers but in general go to your motherboard support site).
4. run MEMTEST ( www.memtest.org ). Errors indicate either bad RAM or incorrect settings (hence using the profile). Most errors pop up in one minute. You should run a two-hour test at least once. If you see any errors, test your RAM one stick at a time. See your motherboard manual as you can't choose just any slot (same goes for two stick).
5. If you use 8GB, use two slots. If you use 16GB it doesn't matter too much, however 4GB modules may be cheaper than 8GB modules (again 16GB is overkill for gaming only).
