i have a gigabyte ud5 r5 mobo and 32 GB of g skill ripjaws x 2133 ram, my motherboard wont let me get it over 1337, ive played with voltages, speeds, everything.

any ideas how i can get it up to at least 1600? higher would be better
 
Solution
Did you check to see if both kits can run stable at 2133?

For 4 modules, make sure each kit is installed in same color slots. You will need to manually set CPU-NB Voltage to stabilize the memory controller. XMP should not be used, it is designed for a single kit of RAM. Typically two separate kits can work at a lower frequency, but there is a chance they can not work together at all, so we'll see. Let us know how it goes.

You don't specify what memory you have. Whether you have a single kit, two kits or four random modules can make a difference. I can tell you the FX CPUs support 1600MHz with two DIMMs per channel and 1866MHz with one DIMM per channel. 2133MHz is for overclocking.

Q:
I want to install more memory, in addition to my existing memory kit. What are my options?

A:
We do not recommend mixing memory kits, regardless of brand or model.

By mixing memory kits together, there may be compatibility issues such as unable to boot or unable to operate at rated specifications.

Each of our memory kit are thoroughly tested to ensure compatibility within each memory kit. And because we have not tested our memory kit with your existing memory kit, we cannot guarantee compatibility when multiple kits are used.

Corsair FAQs:
Which Corsair Memory modules will work with my existing modules?

We strongly recommend matching the module part number as closely as possible in order to ensure the greatest chance of compatibility. Even if you match part numbers properly, we can't make guarantees as to their performance as the modules weren't tested together. Also be aware that when using two kits of memory together, you may need to reduce the speed of the memory due to motherboard chipset limitations.

From the above two memory FAQs, you can see using two kits are not guaranteed to work. Plus your 2133MHz speed is only for overclocked systems. Your chances for getting two kits to work together is not very good.
