Overclocking ram rated for different frequencies

[drddirty]

Hey guys,

Due to a mistake on my part, I ended up with some ram sticks rated for different frequencies. I have 2 x 8gb of G Skillz Sniper Series 1866mhz and 2 x 8gb of G Skillz Sniper Series 2400mhz. I have done some searching around online and tried a few different things, but I cannot get them to run any higher than 1333. Any help would be greatly appreciated, thanks.

What motherboard and CPU?

That may be all they are capable of when paired together, it's not a good idea to mix RAM sticks that weren't sold in the same kit. Especially an 1866mhz and 2400mhz DDR3 kit, im sure they are using different IC's. Also using 4 sticks on a dual channel board can greatly impact what RAM speeds you are able to achieve.

I would set timings to that of the stick with the highest timings. Then slowly start to increase speed.
