IMac eventually crashing after memory upgrade

I have an iMac (21.5-inch, Mid 2010) running on two pairs of brand new VALUESELECT Corsair memories – 4 slots, 4GB each.

OSX (both Mountain Lion and Yosemite) is detecting available memory accordingly – 16 GB 1333 MHz DDR3. But it will suddenly crash, with no explicit link with an app or activity. Returned the old 2GB memories, it works just fine again.

– I wonder if anyone can point me a direction on how could I solve this thing.

So there goes the crash log:
