IC's
Im not talking about "Sour Onion princles"

Btw... Im suprised by the big difference between single and dualchannel.... This must be due chipset...?
Bachus, do you have a RAM-tester? I imagine Corsair have a few....? Can you please by chance test some IC's on it?

JNL / GTS / JNM / GTR, see if ANY hit 1500mhz+ (DDR3-3000) at CL9-9-9-xx

Thanks,
Marc
