RAM: Can I mix CORSAIR memory kits?

We strongly recommend that you do NOT combine multiple kits of CORSAIR memory in your system. This is because our memory kits are only validated for their rated performance when only using the modules included in that specific kit (DIMMs sold in the same box).

If you combine multiple kits, even if they are rated with the same speed, you risk causing compatibility issues such as system stability problems, the overclock profile being prevented from enabling, or even your system being unable to boot.
