Unmatched ram question

[Tripnologist]

I have 2x2GB Corsair PC6400 and 1x2GB OCZ Plat r2 PC6400 kits. Other than an increased chance of my CPU overclock becoming unstable, would I be alright to use them together or should I just use the 4GB kit?
The timings and voltages for both kits are the same.

Using all 4 ram slots will just add more work to the northbridge, that and lessor overclocks (sometimes, not allways) but apart from that there is no reason not to use them all. Aslong as u know that stuff before hand.

Thanks for that. Your answer is what I was expecting, just wanted to make sure.
