How to disable prefetcher in Atom N2600 processor

I am trying to disable hardware prefetching in my system with Atom processor.

I am following the method as per the link How do I programatically disable hardware prefetching in core2duo ?

I am able to execute,

./rdmsr 0x1a4  
366b52488

however, this gives error message

./wrmsr -p0 0x1a0 0x366d52688
wrmsr: Cpu 0 can't set msr from 0x1a0 to 0x366d52688

How can I disable prefetcher in Atom processor ? thank you in advance.
