Upgrade compatibility question

[Shouvanik Sengupta]

I currently have gigabyte b75-md3h motherboard and have 8gb corsair vengeance ddr3 1600mhz ram with cas latency of 9 and 9-9-9-24 timing. I want to upgrade to 16gb. Can I get ram from different brands for the next two slots as long as those two sticks are identical? Can I go for corsair vengeance c10 which has 10 cas latency and different timing but same speed? Or do I have to get exact same sticks again i.e. 1600c9 ddr3 from corsair vengeance series?

All of those ideas might not work. Those ideas are not guaranteed to work by memory manufacturers. You may end up having to run the memory at a slower speed if it works at all.

This is a 16GB kit.
