Mixing RAM dual channels

[oldtimerZA]

I currently have a Dual Channel kit of Geil BlackDragon 1866Mhz RAM installed on my MSI G43 Z77A mother board with a Core i5 IvyBridge processor.
My question is :

I want to get another 8Gb of RAM ,But I can no longer find Geil's BlackDragon 1866 RAM anywhere. So I was looking at the Kingston HyperX Fury red C10 1866 RAM (4Gbx2) kit.

Speed:
both are 1866Mhz

Timings:
Geil Black Dragon: DDR3-1866 CL10-10-10-32 @1.5V
Kingston HyperX: DDR3-1866 CL10-11-10 @1.5V

I noticed that the timings are different, would this cause a major problem? or could I just lower the timings of the one kit to match the other ( note they will be dual channeled in these slots :BlackDragon 1/3 , HyperX 2/4 ).
Would these Ram modules be compatible on my motherboard ?

Thanks for the help.

It shouldnt be a problem.


But rule of thumb is to use an even number of RAM slots.

The motherboard will drop the timings, so that they match. Usually, it's no problem but sometimes, depending on the RAM, you may get issues.

Sounds Good, Thanks for the help. I'll test the BlackDragon RAM on the new timings first, I'll go ahead and order the RAM then. (the sticks are virtually identical in timings and speed , so I'll hold thumbs).

AFAIK, if the speeds are the same, then it doesn't matter what brand names you use. Take it from someone using both Kingston and Transcend RAM
