DDR3 2000 problem

Hola. Tengo un problema con una memoria KHX2000C9D3T1K3/6GX DDR3 2000 mhz y una placa ASUS P6T WS Profesional chipset x58 y Core I7 975, he colocado los 6 módulos de 12 GB profile X.M.P 1 de 2000 mhz volt 1.66 y qpi/dram core volt 1.7 en automático y me da problemas. Me sale la pantalla azul muchas veces, siempre lo coloco todo en automático en la Bios de 1333 mhz DDR3.
¿Cómo puedo subir la la velocidad de forma manual?
¿La memoria es compatible con la placa P6T WS Profesional? ¿Hay otra que sea más aconsejable?

Hi. I've got a problem with a KHX2000C9D3T1K3/6GX DDR3 2000 mhz memmory and a ASUS P6T WS Profesional,Core I7 975 board. I put six 12GB solts rofile X.M.P 1 de 2000 mhz volt 1.66 and qpi/dram core volt 1.7 in automatic, and it gives me problems. The screen turns in blue every time, I always put every thing in automatic in the Bios 1333 mhz DDR3. ¿How can I get more speed in a manual way? ¿Memory is compatible with P6T WS Profesional board?

Officially the i7 processor only supports 1333 MHz memory @ 1.65V MAX. Using faster ram is not guaranteed to work especially when you fill all 6 slots.

It's asking a lot of the processor's memory controller to run 12GB at DDR3-2000. If you're going to run 12GB I'd suggest lowering the memory speed to DDR3-1600 and loosening the timings to something like 7-7-7 or 8-8-8. I'd set all voltages manually rather than using XMP profiles.
