Corsair Ram for iMac late 2013

Hi,

I got a new iMac 27" late 2013, and bought 32GB Ram somewhere else. It's 4x8GB Corsair Mac Memory DDR3 1600MHz PC3 12800 (CMSA16GX3M2A1600C11).

I got several Kernel Panics, but only with the Corsair Ram. Everything seems to work fine if I use the original 8GB hynix.

Memtest shows no problems with the Corsair Rams at all...

My questions: Am I right to suggest that the Corsair Ram is causing the Problem, altough memtest shows no problems? If yes, should I return the faulty RAMs and get the same as replacement or would you suggest different RAMs? If yes, which ones? 🙂

Here's the Diagnostic Report from after the last Kernel Panic:
