WebJan 5, 2016 · 2. In the paper Compiler Transformations Meet CPU Clock Modulation and Power Capping 2016, it was mentioned on their slides that you should write a specific value to IA32 CLOCK MODULATION (0x19a) MSR, so the correct register to change the frequency is 0x19a. When I write a value like this: sudo wrmsr 0x19a 0x12. WebJan 20, 2009 · asm volatile ("RDMSR;":"=a" (eax),"=d" (edx):"c" (ecx)); and see if eax/edx are still 0. If that's still the case, try using MSR (ecx = 0x1B), or another well-known MSR. ECX = 0x227 and using your code still returns 0. However, ecx = 0x1B returns edx = 0 and eax = 0xfee00900 (both using your code and mine - which should rule out pointer troubles) st richard gwyn catholic high school staff
