You need minimum low density DDR3 1066 x64 modules up to 4GB each.
CL9/ DDR3 1333 modules can run CL7 @ 1066 and are a very good idea.
DDR3 CL11 @ 1600 will probably run CL7 @ 1066 also. You don't need L modules.
Those both look good. The CL11 1600 modules will be a little more future proof. But they will both run CL7 @ 1066 on that machine.

Well I bought the cl11 model and my pc stuck every 3 weeks. Freezing..

Now I hope they will agree to change the already used memory set.

I think the speed is over what I the motherboard can handle.
