Meeting 1600MHz and 2400MHz RAMs on a 1600MHz motherboard

[semrola]

I have a MB: Asus B85M-E
I already have a two module kit plugged in: Corsair Vengeance Green 8GB (2×4GB) 1600MHz CMZ8GX3M2A1600C9G
My question now is: can I plug in a Corsair Vengeance 16GB (2×8GB) 2400MHz CMY16GX3M2A2400C11A?
I am a little concerned about the voltages...do you think both RAMs could meet at 1.5V?

Mixing ram that uses different voltages and timings is a bad idea, as it usually has issues if it even works at all.

Don't all plugged rams adapt to the slowest one?

Frequencies yes. But not voltages. Mixing ram is hit and miss. For the best chance of compatibility you want to try and match the specs as close as possible and even then there could be issues. This is why ram is sold in sets.

Best bet w/ those is to try the 2x8GB setand set up for 1600 at 9-9-9-24 1.5 and see how they do, should prob run fine, then add the 2x4GB set and might need to raise DRAM voltage to 1.55 for the 4 sticks and mixed amounts (2x8GB in slots 1-3 from CPU, 2x4 in 2-4) this will keep the DRAM at 12GB in each channel and dual channel enabled
